Title: [ANN] official NovaCoin thread - the original PoS+scrypt coin. --POOL LIST--
Post by: xorxor on February 11, 2013, 10:37:40 AM
NovaCoin was the first PPC fork, but not a clone!
new versions ale coded standalone, not from new ver. of PPC.
 
major changes:

1. Scrypt chashing!
2. initial reward of 100 not 10000
3. slower reward drop
PPCoin cuts a half from reward for every 16x diff adjustment.
NovaCoin cuts a half from reward for every 64x diff adjustment.
4. POW difficulty adjusted for scrypt
5. POS difficulty adjusted for 100 times less coins.
6. ROI for POS changed to 0.05 coin per 1 coinyear [dynamic from 4.1]

Its based on the broken version of PPCoin then? He didn't even wait for the fix before cloning it?

SCAM COIN - DO NOT USE

This is a SCAM coin. Here's why:

> Over 200k has being premined secretly by the developer. Every single premined cryptocurrency has died - the only currently surviving ones are those that are NOT premined

> 110k of the premined coins have being given to BTC-e as a bribe for them to accept this worthless coin.

> BTC-e censors chat, removes all negative criticism of NovaScam.

> Balthazar is still trying to deny that the premined coin exists, claiming a 60k premined figure, but BTC-e admitted that they got 100k NovaScam premined coins!  ;D

SCAM COIN - DO NOT USE

1) Fast checkpointing is still active.
2) PoS isn't active for now, because there are no coins with 30 day age
3) Fixes can be merged after upstream update.

So, there are no reasons to wait.  :)

Is proof of work really only there as a way to distribute coins initially, or does it also rely on it for timing the blocks, that is, to try to make average time between blocks meet some target duration? I am wondering whether one could turn off proof of work entirely to make a purely proof of stake coin and use some other method of distributing coins initially. (Even maybe something as simple as getting a hundred or few hundred people lined up as initial stakeholders and dividing the total number of coins to them as initial stakeholders right from the start.)

According to Gavin, PoS-only system can be easily DoS'ed by generating huge amount of invalid PoS blocks.


Title: Re: NovaCoin - balthazar's PPC scrypt fork
Post by: markm on February 11, 2013, 12:41:30 PM
Hmm if there is a minimum stake level though, maybe adjusted like difficulty, the maximum number of proof of stake blocks that could be generated would be however many times that minimum the total number of coins existing happens to be at that time.

For example if there are 21 million coins and minimum stake of 21, the clients could refuse to relay any blocks containing less than 21 stake thus would not have to deal with more than one million proof of stake block candidates in any one block-timespan.

If stake takes time to be useable, like generated coins, then you also get to divide again by say 120 if its 120 blocks, or the 500 or whatever that PPCoin makes stake wait before being unusable.

coin price is crashing can not mine on the network because getwork takes 30s and the difficulty won't adjust fast enough because balthazar set it at a max of 1% per block...  this is especially bad for the pool which is getting stales above 50%.  the coin is basically dead in the water hours after its release.

So we have another coin where the source code is not readily available.

Are people really downloading and installing these daemons blindly? Anybody installing these "mystery" coins ever hear the term "Trojan Horse"?

The only files available on the source forge site are compiled installers.


If somebody could point us to the source code, perhaps the coin could be taken more seriously.

No, I am not going to run the installer to get the source code, as with the other legitimate coins, the source should be readily available.


Perhaps the link to the source code should be in the OP.

Thank you for the link Sunny.

Yep, I deserved that, I just let my concern over the sourceless (last I read) RUcoin get the best of me. I just wanted people to be careful about what they install, especially in the realm of cryptocurrencies.

A strange thing to do, release a coin that cannot be mined right now and have it available on the exchange.

If it is unminable then how does BTC-E have Novacoins then?

How did they mine or get them?

Does this sound like a way to make people spend their Bitcoins buying them as they cannot be mined?

This are just questions and I have no opinion either way, just speculation.

Balthazar released it yesterday on the network during which time some russians mined 200,000 or so coins, then today when it was added to BTC-e everyone started trying to mine it.  Because of the retarget algorithm stale rate even solo mining right now is extremely high (getwork takes forever, so a lot of people's hashes are useless).

see this thread https://bitcointalk.org/index.php?topic=114712.0

Right now it's a lot of solo miners fighting amongst each other to get as many blocks before the difficulty heads into the double digit range.  People are still getting blocks, but only those with massive hash rates because getwork takes so long.  It's the same problem with every alt coin release that doesn't have a suitable difficulty adjustment algorithm.

Sadly what is happening right now is basically a premine amongst the parties who have the greatest hash rates, since the probability is that they will obtain the majority of the blocks

The russians have it right

LOL right NVC was announced ahead of time right? Which means no premine? Don't make me laugh.

Oh and you think this is trolling? LOL...I haven't even started little boy.

You still haven't shown why I would be butt hurt. I think it's humorous that NVC was added before PPC to the BTC-e exchange even based on broken code lol.

This is the equivalent of bankers scratching politician's backs in the real world. It's not what you know, it is who you know. Obviously you are good friends with the owners of btc-e. Good for you.

It doesnt remove the joke of NVC added before PPC and NVC not having a publicly available launch date prior to starting the chain...which equal premine lol...

So fail...lol so fail...  :D :D :D

There are only one "problem" - difficulty is high and growing.

I believe it is the only problem for You . I have great ISP, I'm close to Russia, i have a lot of hashpower.
impossible to mine.
 even 20 hours ago, with lower diff and 9 connections, i was finding blocks one by one, but all rejected for no reason, not stales.

I have no idea why only in russia blocks are not rejected.


Looks like it either has problem with cgminer, or it has problem with getwork for solo mining. Blocks are being rejected due to wrong hash submitted via getwork. Balthazar, are you sure that getwork is properly supported? Have you tested with cgminer?

I think that it's result of 120s expire time, which is default value for cgminer and hard-coded value for reaper. I seen people which mined it at 4-8 mh/s... Of course, they got stales, but stales rate not so dramatic. There is no magic. :)

P.S. Tested it with reaper at diff 0.0004, got almost 100% of stales... Then I switched to cgminer with -E 1 and got "only" 55% stales at this difficulty.
P.P.S. Target is 6 blocks per hour (like PPC and Bitcoin), so situation will normalize in near future.

For blkmon, I use:

Code:
#!/usr/bin/env python
from jsonrpc.authproxy import AuthServiceProxy
import sys
import os

access = AuthServiceProxy("http://RPCUSER:RPCPASS@127.0.0.1:8332")
blockcount = access.getblockcount()

while(True):

        if newcount > blockcount:
                os.system("killall -s SIGUSR1 pushpoold")
                sys.stdout.write("B")
                sys.stdout.flush()
                blockcount = newcount
                sleep(1)
        else:

Good idea. Are you adding it to both the SHA256 and scrypt sides?

How about also adding merged mining? On the scrypt side that would be a first, and people would have something to merged-mine alongside litecoin. Though personally I am more interested in the merging with the SHA256 side.

Hm... By the "SHA256 side" you mean PPCoin?

Oh never mind I was thinking of RUCoin - both types of hashing. All you Russian coins look alike hahahahah. But adding it to PPCoin as well would be nice, sure.

Novacoin suffers the same issue as PPCoin did with the base58.h file.

My commit merged into the PPCoin official development Tree allows Vanitygen private addresses to be imported. This also corrects the Base58 private key version the daemon produces when dumping a private key.

https://github.com/Hartland/ppcoin

The patch file should work exactly the same in Novacoin, with no changes needed. I can fork and request a pull, or the Novacoin developers can just patch it themselves, either way is OK with me.


Vanitygen will need  -X 08 switch to produce Novacoin addresses. First digit of the pattern must be "4".

I figured it out.


I think even with correct algo, with solo mining you see no stale rate until a block is found,
and perhaps network connection is all the time equivalent to 90% stales and there is only
very small chance to get the block. No way to know it.

So, pool are a necessary middleman.

Of course, if you can find valid block every 10 minutes... ;D

It's funny how NVC gets added to the exchange before PPC.

Funny  haha? I think it's seriously odd that a fork of PPC would be added before PPC itself.

+1 let's add the broken code from the fork...not the original. Sounds like a great idea! Let's do it!

I think we can also assume the hardware mining the initial 110k did not just "switch off" after the 110k.

I'd be willing to bet closer to 200k is in the same person(s) hands - so about 74% of the currency (currently).

Im going to put up a proofofstake.com page with NVC metrics later, this should indicate all of the above.

It seems that you forget --scrypt option.

110k of 273k is not "more than 50%". Also, don't forget about mining... Now network creates approximately 2000 new coins per day, for example.

I did solo mining Feb 11 - Feb 12 and all was done. I found more than 130 blocks with 24,49 - 20,37 reward. (9 Mh/sec)
But since Feb 13 it was rejects only.
Now mining is working fine with coinotron.com (less then 1% rejects) (I also tried http://novapool.zapto.org/ but got 50% rejects on February 13, but pool is alive and working now)

No, it's too slow. You can get ~250-270 khash/s.

Are you increasing the intensity? (g>i>select device>enter intensity value) when cgminer launches it's going to be low by default unless you set the parameter in your config.

Maybe when you are solo mining your mining software doesn't stop working on a block if a new one is found? I think this feature is called "long poll." I'm not an expert Bitcoin miner, so I hope someone will verify this for me.

I think stratum is a bidirectional protocol so it's built to do this even better. Long polling is a bit of a hack of the Bitcoin client RPC interface. Stratum is a fresh start and designing the protocol to be more appropriate for what Bitcoin has become. RPC was fine when Bitcoin started but its no longer appropriate.

I'd suggest moving to Bitcoin mining temporarily because you aren't going to be able to mine NVC efficiently enough for it to be worth it. You can still mine TRC, PPC and FRC with p2pool IIRC all of these have p2pool set up and are not dependant on coinotron.

24 over the target ? wait waaat? do you have any idea what hashpower is needed to mine 24blocks a day with current difficulty over 11 ? I think you ment rejects below target.

Ah well good to know then.  I thought there was a problem and brought all of my rigs down.  I'll get 'em running again.  And each block contains roughly 16.75 NVC?

By the way, how can you see  what the current difficulty is? I don't see a debug menu to type: getmininginfo

Edit: Also, what is an under target reject? Never seen that before when solo mining other coins.

you can see in in the miner window , cgminer shows about 65k*diff which is about 720k right now, dont know why and I heard BFGminer shows it correctly. also i missed one zero :( , so its more like  2000kh/s .

 recejts like this are ok :
rejected 39f92hac93 diff 620k/720k  gpu 0 pool 0  [difficulty below target]

this is a real find:
BLOCK! 39f92hac93 diff 1.23M/720k gpu 0 pool 0

and this a a bad reject i can't explain
rejected  39f92hac93 diff 1.23M/720k gpu 0 pool 0

ant thit is a stale:
rejected  39f92hac93 diff 1.23M/720k gpu 0 pool 0 [unknown work  - stale]

all of the top of my head so migh be a little wrong but you should get the point.

Working on p2pool compatibility, so some fixes released in 0.2.4 build.

1) https://github.com/CryptoManiac/novacoin/commit/440991a0f8dbdd6147e56ec55e3423429cee6e90

Adds new RPC call, which allows you to generate new public keys.

2) https://github.com/CryptoManiac/novacoin/commit/3b2f04b998fca87c3f5e57b6fbb78f01da699a34

Adds incompatible changes in blocks signing, in order to make this transparent and decentralized. You need upgrade your client to new version before February 24.

The disclosure of problem:

Quote
Each miner in p2pool has his own output in coinbase. If there are N users, there will be N+2 outputs. Each of N outputs pays to miners according to their PPLNS work, and vout[N+1] pays donation % for developers of p2pool. The last output pays nothing and contains service information.

Even if we modify p2pool to force it make vout[0] owned by winning share submitter, it's not a solution, it's only workaround. This will remove possibility of block construction by other users (not a miners of winning share).

I.e. only block founder will be able to submit winning share into cryptocurrency network. Because only miner of winning share has corresponding private key for vout[0].

If submission of block by winning share miner fails, nobody will be able to replace him, and block will be lost. Even if other p2pool nodes received all block data through p2pool network.

This problem can be solved with my patch, this allow users to sign block by using any private key, if this key corresponds with one of vout[N].

You can download binaries for linux x86_64/x86 and win32 here: https://sourceforge.net/projects/novacoin/files/

Working on p2pool compatibility, so some fixes released in 0.2.4 build.

1) https://github.com/CryptoManiac/novacoin/commit/440991a0f8dbdd6147e56ec55e3423429cee6e90

Adds new RPC call, which allows you to generate new public keys.

2) https://github.com/CryptoManiac/novacoin/commit/3b2f04b998fca87c3f5e57b6fbb78f01da699a34

Adds incompatible changes in blocks signing, to make it decentralized. You need upgrade your client to new version before February 24.

https://sourceforge.net/projects/novacoin/files/

Good job!  :)

Several other things to take note:

1) Each coinbase output must have value >= 0.01 coin, p2pool needs to be aware of it otherwise block could get rejected.
2) If coinbase size is greater than 1KB then it needs to pay 0.01 fee per additional KB, otherwise block could get rejected.
3) Make sure all the transaction timestamps not to exceed block timestamp (throw out those tx with larger timestamps) or block could get rejected.

Already thought about it, PPC/NVC p2pool will destruct 0.01 coin per each block by sending it to non-redeemable script. To satisfy the protocol.

I love the misconceptions on this forum:

1. If you speak the truth you are labeled a TROLL.

2. If you speak the truth and shove the truth into people's faces you are labeled as BUTTHURT.


I'm going to make my own misconception attempt here on Balthazar:

Balthazar, because you insist on making yourself out to be someone who tries to side step every accusation concerning the SHADY release of NovaScam in an effort to be viewed as INNOCENT, you are nothing but a RealSolid wanna-be gay momma's boy pansy that runs around your front yard with a tutu twirling in circles to rid yourself of the shame you have bestowed upon yourself in releasing a "NEW" coin based on broken PPC code.

Yay! Be proud, RealSolidly gay too!

Both parties would have their coins held up for half a year.

If you're so sure NVC is a short-term scam, put your money where your mouth is and pony up some more attractive odds.

Offering coin flip probability isn't a very impressive offer, nor does it do much to convince people you truly believe what you're saying.

It's actually an argument in favor of NovaCoin, because most AltCoins don't make it that long!   ;D

PPCoin DEVELOPED the PoS protocol.
And so, they don't use it? Just developed to forget about it? :D You need to fix your logic, I think.

Especially for you:

1) PoS is the protocol, just a terms and conditions.
2) PPCoin is the reference protocol implementation, and follows this terms and conditions. It uses the PoS protocol.

-------

0.3.0 binaries:

https://sourceforge.net/projects/novacoin/files/?

Repository:

https://github.com/CryptoManiac/novacoin/

-------

Changes list:

1) Merge with v0.3, without time conditions for protocol switching, because there are no PoS blocks yet (we support 0.3 protocol only).
2) Add new RPC calls.

PPCoin DEVELOPED the PoS protocol. You ripped it off.

Come back when you developed something of your own  ;D ;D ;D

Im not defending nvc now, but you are a retard. lol, google: wiki open source
plus search in the forum for sunny king's posts

Uh forgot, you got a contract for ltc @ 700usd

By your mind, LTC ripped of the bitcoin code, AND the scrypt too
There is a difference between building on someone's code versus stealing something and giving the impression that you actually created something with a worth  :D :D

Did anyone take up on the btc bet?

Hey Balthazar,

When you open up your IDE and scratch your ear, thinking about innovative cryptocurrency ideas, and actually write code rather than just merging and "Find and Replace: PPCoin NovaCoin", come back ;D ;D ;D

1. Why did you create a cyrptocurrency with security vulnerabilities that is already known?

2. Why did you premine?

3. Why did you post this to your Russian friends before letting the whole world know about it? See question #2.

4. Why are you not willing to bet on novacoin actually being used?
 
5. Why did you not even bother changing the readme file? "Requests to reopen closed pull requests and/or issues can be submitted to QA@BitcoinTesting.org. "

Answer those 5 questions please.

Answer those 5 questions please.

Why in current world, there're so many men behaving like women?

Answer: because in current world, people are more independent and seek freedom/freewill. So if there're no outside force, people will enjoy their pure nature. So some women-like men can behave what they like & what they really are.

This also answer your questions, this is a free world, people can do as they wish or they like or they feel safe or they feel satisfied. If you don't like it, can't you ignore it. Just like I don't like men having female behavior, but this is freedom although I don't like them but I have no ability to force them be like man, so I ignore too.

You fail to realize that even if I new Russian, I would not have known to look in the Russian subforum for a coin launch.

Also you fail to realize that Hawaiian isn't as useless as you think. Japanese is much more useful yes, but you also failed to acknowledge that.

Why does cgminer show difficulty at 960k ? lol

From the CGMiner FAQ:

Code:
Q: Why do the scrypt diffs not match with the current difficulty target?
A: The current scrypt block difficulty is expressed in terms of how many
multiples of the BTC difficulty it currently is (eg 28) whereas the shares of
"difficulty 1" are actually 65536 times smaller than the BTC ones. The diff
expressed by cgminer is as multiples of difficulty 1 shares.

You fail to realize that even if I new Russian, I would not have known to look in the Russian subforum for a coin launch.

If you "new Russian" you would have been able to read the posts about NovaCoin when they appeared in the unread posts/recent posts lists.  And you'd be more likely to visit the Rus sub too.

You are free to launch an AlohaCoin on the Hawaiian sub, so stop hating and being so jelly.

What does me being from Hawaii have to do with me acting like an emo chick on her period?

You fail to realize that even if I new Russian, I would not have known to look in the Russian subforum for a coin launch.

If you "new Russian" you would have been able to read the posts about NovaCoin when they appeared in the unread posts/recent posts lists.  And you'd be more likely to visit the Rus sub too.

You are free to launch an AlohaCoin on the Hawaiian sub, so stop hating and being so jelly.

Take your lithium, Midol, and Prozac, you silly haole!   :-*

Does not matter, NovaScam has being premined, which means that it is a scam coin just like Solidcoin.

So, I have setup nvc for solo mining w/ cgminer.
Running novacoin-qt -server with these settings:
rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcport=9332
daemon=1
server=1
gen=0


Cgminer says its connected to 127.0.0.1 diff 1M without LP as user username

I have -E 1 specified in cgminer...

Is this correct?! the 1M part?!

Very amusing. I'll believe you can actually write in Hawaiian when you come up with anything that didn't come from google pages about swearing in Hawaiian.

You were funny when you were trolling Coinhunter but those days are long gone now. Now you just troll anyone who isn't strongly pro-LTC. It's ridiculous. With the upstart and pre-mined NVC being worth 4 times more than your precious LTC the free market has abandoned you.

LOL yeah I surely googled "Ku kai pa'a"...unlike you I am Hawaiian and grew up with the language. You can assume I googled the statements I made or you can accept the fact that you had to google your petty little "fuck off" statement to make a point.

What is ironic about your last statement is that even Coinhuner and his minions touted how awesome solidcoin was because its price was 0.02btc to 0.04btc. Now where are those fools? Oh and also where is the price of solidcoin? oh right...sub 0.001 btc.

The term "troll" is used with little or no meaning now days. If you disagree with someone, you're a "troll".


FREE-MARKET? NVC is controlled by a handful of people who premine the fuck out NVC. Much like FRC and PPC and TRC and RUC....NVC is no different.

No such thing as FREE-MARKET buddy when it comes to NVC if a select few hold 90% of all the NVC.

Good luck with that logic.

I’ve lived on this island for ten years, ten years! Every July and part of August.

Nature abhors equitable distributions.  That's why the Pareto Principle (AKA law of the vital few) exists.

It's perfectly natural for about 20% of the people to hold about 80% of the *coins.

Early *coin adapters are always rewarded for being innovative, informed, and active.

You're just grasping at straws, in desperation to find something, anything to use against your hated rival scryptchain.

Novacoin is innovative in that it is the first altcoin to combine proof-of-stake with scrypt.

Any other dumb questions, Mr. Fresh Off The Cruise Ship?   :)

Litecoin is dropping like a brick.  It's gone below $0.07/LTC and there's little support to prevent it from falling to $0.01.

Maybe you shouldn't have traded all your silver for LTC?  Smooth move smoothy!!!   ;D

Maybe you shouldn't have traded all your silver for LTC?  Smooth move smoothy!!!   ;D



iCEBREAKER given you appear to be in special ed your whole life let's get some facts out in the open:

Fact #1: The definition of the word INNOVATIVE by GOOGLE says "featuring new methods, advanced, and original."
Innovative /ˈinəˌvātiv/ Adjective (of a product, idea, etc.) Featuring new methods; advanced and original.

        a. NVC does not feature any NEW methods. Just reuses other people's methods via copy and paste.
        b. NVC is not advanced. Broken code (PPC) + Working code (LTC) = Broken Code
        c. NVC is only original in the sense like a kindergartener cuts out magazine pictures, glues them to construction paper then calls it a "masterpiece".

Fact #2: You presume I am fresh off the boat, despite any proof. In FACT this was your attempt to change the direction of the conversation after being proven like a bitch that you can't read Japanese nor Hawaiian without googling it.

        My perception of our conversation:

                 You: I know I can paint better than Michelangelo in his sixteenth chapel.
                 Me: Dumbass it is the "Sistine Chapel".
                 You: Hey Mr. Fresh through the doors of the Catholic Church your LTC investment is tanking.
                 Me: Wrong! Divert more bitch! LOL  :D :D :D


Fact #3: Litecoin has been around for 16 months. No premine. No bullshit. Its price in terms of fiat has risen 1400% in the last year. So no it's not dropping like a rock. lol

Fact #4: Yes it has gone below $0.07 but I disagree that there is not much support all the way to $0.01/LTC. Wanna bet? Let's see how big of a pussy you are. I bet you that Litecoin will not stay at $0.0100/LTC or lower for longer than 24 hours in 2013. Now show me how big of a pussy you are to back pedal on your statement above and not back it with your money. Care to make a wager? LOL

Fact #5: Sold my silver when spot was $32.25 and litecoin was at $0.055. Two things you are wrong on: 1) I didn't sell all my silver. 2) My investment is still profitable. 3) I didn't convert all of my BTC I got to LTC when selling silver. Keep assuming more dipshit lol.

You are really showing everyone how PRESUMPTUOUS you are and how when proven to be a dumbass who doesn't know what he is talking about, you simply...change the subject lol. Yeah nice try RealSolid wanna-be.

 :D :D :D

Tell that foo, uncle! Representin' LTC to the fullest. When they talk shit, we wanna make sure we mash their asses. LGOD!

This is funny. :)

I don't really understand the hostility from either side. The fact that NVC is taking miners from LTC is fine with me. LTC has shown a much stabler price over the long run and the lower difficulty is fine by me.  8)

LTC also has more sites / merchants / everything so I don't see NVC out performing it long term unless NVC catches up from that aspect. Right now I just see it as the hip new coin everyone wants a piece of... once that wears off I think the price will crash because no one will want to actually use it... everyone is buying hoping to capitalize on an upswing. IMO.

Proportional payout system, payout after 10 confirmations, UI without support of language switching.

P.S. I forgot to say, the pool fee is 5%.

all pools are dead / scam? / frozen


WARNING  

nvcpool.ru IS A SCAM

WARNING



pool is operating few days now, was up to 50Mh for last days, and zero blocks, there is a chance of bad luck like this, but kinda equal to finding 3 btc blocks in 1 hour on a cpu.


i might be wrong, somebody on btc-e chat confirmed that pool newer paid anything.
now hethead says it was paying at the beginning so it might be simply dead, not scam.

Some new commits in repository:

1) Actual gettransaction implementation merged from bitcoin, you will be able to get information about any transaction, not only yours.
2) The getblock/getblockbynumber functions output improved, now it can provide the full information about transactions, which was included into block.
3) Checkpoint at block #8700 was added.

P.S. The nvcpool.ru switched to PPLNS, as I can see. They had some serious bugs due to this, but it's fixed now.

I can confirm now, nvcpool.ru working like a charm , no stales! [99,8% eff.]

any information for how long pool was not counting shares? how much nvc was lost ?  are they taken by the pool or lost?

All prop blocks were paid.
After that, all blocks pplns paid.
You can see it on your transactions.
And see a chart mining per day.
I mine with 600kh and I:
27 --- 6.07 nvc
28 --- 4.95 nvc
1   --- 5.79 nvc
2   --- 4.84 nvc
3   --- 6.28 nvc
It is more than other pools.
And you can ask other users.
This lucky pool.
Failures was not.
Or you can try again.
Pool pay very quickly.
See balance and withdraw NVC.
I do not think that such questions should appear until the pool is present fortune. And the fastest possible output.

Testing p2pool in mainnet now.

https://github.com/CryptoManiac/p2pool

A lot of deads and stales now. It's because of too low startup shares difficulty and it will become to normal later. ::)

P.S. The NVC P2Pool target shares rate is 1 share per 30 seconds. Also don't forget to update your NVC client to 0.3.2. It's required for p2pool.

Nobody gives a shit about NVC anymore. It's dying, price is falling, this Pump 'n Dump is over. Let it go.

I thought mokes were supposed to be mellow people, living simple lives consisting primarily of pleasant activities such as fishing, bird watching, surfing, BBQ, orchid collecting, and being racist towards white people.

The funny thing you missed is that you stereotyped me. Good job at being ignorant in that manner. I bet you now think we have monkeys in Hawaii and we live in grass shacks eh?

Your comments keep digging you deeper showing how truly ignorant you are. So hows the translation of my 3 sentences to you?

You keep avoiding it? Why oh why? lol...i think we both know why.

Troll harder, this is getting boring lol

 :D

P.S. - My scam accusations, if you ask the majority of the alt crypto community, have done the needed damage to novascam. It has been outed as what it is. Ask the majority of the community, you will find they agree very strongly with me. Once again you failed. Good luck next time. Come again and play. Also bring the translation of what I said to you (now going on 2 weeks)...still waiting...lol  ;)

You need to disable stratum (--no-stratum for bfgminer or --fix-protocol for cgminer), and this error will go away. I'll try to find the reason later. I think this happening because of difference between NVC/PPC and BTC transaction formats.

P.S. updated code in git, commented out X-Stratum header setup to disable Stratum support by default. Win32 build (https://sourceforge.net/projects/novacoin/files/) is also updated.

Updated to add support for compressed public keys. So, now it displays generation txns destinations correctly (demo here (http://novacoin.ru/block/00000000058a5a667478fcbe08653c5daccd4a6a660cf4c0d5c324230cd93570)).

ABE database rebuild is required after applying this update.

P2Pool was updated. It's neccessary to apply this update after majority of hashing power upgraded. It fixes coinbase size calculation inaccuracy, which caused generation of invalid blocks in some cases.

More than 51% of p2pool hashing power covered by the new version. If you are not updated yet, it's highly recommended to apply this update immediately.

I don't see

        help='generate payouts to this address (default: <address requested from bitcoind>)',
        type=str, action='store', default=None, dest='address')


Why we can't set external novacoin address as default payout address?
Why you disabled this nice feature?


Title: Re: [ANN] NovaCoin - Balthazar's PPC + scrypt fork, pool list
Post by: Balthazar on March 24, 2013, 06:49:29 PM
It was removed due to NovaCoin's protocol limitations. For each block the NVC network requires digital signature from the owner of one of the destinations in coinbase transaction. Thus, the generation is possible only with addresses that belongs to miner. You are able to specify custom public key by editing cached_payout_pubkey file, but it's not recommended. It's risky due to possibility of invalid blocks generation.

v0.3.3 released. This release fixes entropy bit calculation problem (https://github.com/CryptoManiac/novacoin/pull/2), which was discovered yesterday.

Sources: https://github.com/CryptoManiac/novacoin/
Binary builds: https://sourceforge.net/projects/novacoin/files/

You need to update your nodes as soon as possible, otherwise you risk to be affected by blockchain fork which will happen soon (deadline is approximately ~30.03.2013) for unfixed clients.

P.S. Thanks to SunnyKing for help with investigating this issue.  :)

I sent 1 nvc to that address as a test and it didn't show up. any ideas?
If it was unconfirmed transaction, try to force unconfirmed transactions re-broadcasting:

Code:
novacoind resendtx

I think that it will appear soon, but we can check it. Can you publish the txid?

If it's confirmed transaction, it will appear during block chain sync.

v0.3.3 released. This release fixes entropy bit calculation problem (https://github.com/CryptoManiac/novacoin/pull/2), which was discovered yesterday.

Sources: https://github.com/CryptoManiac/novacoin/
Binary builds: https://sourceforge.net/projects/novacoin/files/

You need to update your nodes as soon as possible, otherwise you risk to be affected by blockchain fork which will happen soon (deadline is approximately ~30.03.2013) for unfixed clients.

P.S. Thanks to SunnyKing for help with investigating this issue.  :)

Thanks to both Sunny and Balthazar for the quick warning and fix :)
We are re-downloading the blockchain now with the newest client.

It will be more easy to find stakes by using listtransactions RPC. They listed as "immature" and "generate" transactions.

Is there NovaCoin testnet online?  if yes, is Novacoin-Qt with "testnet=1" expected to connect there automatically? 


Thank you!

It has testnet support, but there are no nodes online yet. You can start 2 clients with -testnet option and it will create "testnet" for you.

EDIT: Created 2 testnet nodes, so you can start mining testnet blocks or another testing.

0.3.4 hotfix build is ready. It adds new hardened checkpoint at block #13560.

If you don't have problem, which is described below, you can ignore this. But anyway, it's recommended to apply this update, especially if you running mining pool or another service. It will prevent downtime possibility.

If you see "Invalid checkpoint found" message and your client switches to safe mode, you need to install this update and re-download the blockchain. By the way, with win32 client you don't need sync og the whole blockchain, you can use files from the blockchain snapshot.

Hello Everybody  :)

I'm looking into NVC because I find it intriguing and am fed up with the gov-s.

Any recommendations on a pool selection and miner?

I currently use cgminer with 4x7950-s and am getting 2.6Mhash/s.

There are a lot of people out there who think NVC is a scam due to the circumstances when launched but I see it as a bold move.

Either way, I've always been drawn to the east side  ;)

Mad props, Balthazar!

The reason of situation is the fast difficulty grow up. I didn't expect that so many people will come into the network soon. I thought that we have some time to generate enough coins for this PoS difficulty.

Ah, what do we have here..
We have failed scammer, who known as TradeFortress.

Without exaggeration, I know more than you ever will be able to know. It obvious that you have no chances in the real discussion with me, because your conversation abilities are limited with simple trolling. So I don't want to waste my time.

But you need to know that the person who is so careful that he never makes a mistake is unlikely to achieve anything of real value. If you don't know how to do something, have a go, don't be afraid of being wrong. If you are not prepared to make mistake, you will never come up with anything useful.

Have a nice day :D

Simple p2pool guide for windows users:

Hi,

Is there somewhere a detailed guide on how to use p2pool with nvc?

The readme file attached was not helpful to me at all using the precomplied .exe.

Thanks,
balu
It's quite simple.

1) You need to run novacoin client in server mode, just like in case of solo mining. Create file novacoin.conf in

C:\Users\Your user name\AppData\Roaming\NovaCoin

with contents like this:

Quote
rpcuser=user
rpcpassword=password
server=1

2) Start client and wait for syncronization proccess
3) Double-click on run_p2pool.exe, wait until shares chain download will be completed
3) Point your miners to http://any_user:any_password@127.0.0.1:8336/

But remember that you need enough hashing power to get at least 0.01 coin in PPLNS reward, because NVC/PPC has no support for outpoints volume less than 0.01 coin. It's serious limitation, I'm agree.

P.S. Binaries download page: https://sourceforge.net/projects/novacoin/files/

NVC implementation of P2Pool uses PPLNS with N=2880 (shares spacing is 30 seconds approximately, so 2880 shares is 1 day), but minimal payment is 0.01 coin. It will pay you for each block found by pool, according to proportion in last 2880 shares.

Quote

You can see your estimated reward at the statistics page, it's available at http://127.0.0.1:8336/static/

If you want a profit calculator, you can use this one http://nvc.khore.org/calc

Quote
what is the expected payment cycle with around 2Mhash
With the current pool hash rate average round time is 10 minutes.

If you have no such hash rate to get enough proportion in last 2880 shares, you can mine at http://nvc.khore.org. It has no payment limits and mined coins are available after 10 confirmations. But it's centralized...  ;)

The NVC & PPC transaction minimum outpoint value is 0.01 coin, this protocol limitation was introduced in order to prevent high amounts of unspendable "dust" creation. It's simply impossible to create valid block with such transaction.

I'm still working on it. It isn't quite simple due to decentralized nature of p2pool. Maybe the replace of rewarding system with variant of CPPSRB will be better and simplier solution. ::)
As temporary solution we can split nvc p2pool by launching more networks, one or two in addition to current. I'll start two additional p2pool networks tomorrow, I think.

I must ask, what kind of hashrate do you have if there is no shares coming in?

About 1000 kH/s. Currently it should take about an hour to find a share. I found a few shares since I wrote that but yesterday it took only 15 minutes or so to find one. Mining is profitable right now and it is very tempting to build some more rigs but electricity is expensive here and it might not be profitable for very long.

I only have ~2000 kH/s pointed here and it is literally flooding accepted shares in. Can the difference of finding shares be that big with such a "small" difference in hashrate?

I don't think splitting up the p2pool will only be a positive thing, wouldn't it bring some drawbacks too?
It will allow users with small hashrate to join another newly grown network with lower shares difficulty. I think that it's safe enough to try. :)

Do I understand correctly that if the difficulty of P2Pool shares is high enough people don't have a change to find a share with too low hashrate? If so, is there any way to know what would be the lowest working hashrate for a given P2Pool shares difficulty?

I wonder if we are talking about the same shares? I mean the ones within the p2pool network, not those that are reported by cgminer or reaper.

Oh, this is slightly more complex than I first thought. I must have had some intense lucky strike earlier because of the continues incoming spam on my wallet. So those shares reported by the miner are not directly the shares you are paid for, atleast they don't seem to add to the "Current payout" in regular basis?

I see the P2Pool program is reporting "Expected time to share", is this what increases the "Current payout" once I get the share from P2Pool?

Shares in two places, hard to know what is what  ???

Anyone mining NVC at nvc.khore.org? If so, what is your invalid percentage? I just started tonight. Seems stable enough, but my invalid percentage is ~8%. When mining LTC at ozcoin using the same setup, cgminer flags, etc I had less than 1% invalids. Thoughts?

Also, is there a dedicated thread for nvc.khore.org? I searched and did not find anything.

I'm pretty sure that you would be better off mining at p2pool. I've noticed that even miners with huge hashrates tend to use pools. They wouldn't do that if solomining were more profitable.

It seems that llvm-g++ can't understand AT&T assembler properly. You can try gcc, this may be helpful in your case.

Title: Re: [ANN] NovaCoin - Balthazar's PPC + scrypt fork, pool list
Post by: Balthazar on April 07, 2013, 07:25:37 PM
DOA shares are not paid. Orphaned shares are partially paid in the p2pool, in case when orphaned share generates a block. So, you need to enable --submit-stale feature in your miner to prevent lost of the valid blocks.

Hmmm...

I try to use but qt-client crash many times...

So P2Pool lost conection, than mining are useless...

There is a fix? I using Windows 7 and Windows 2003 Server.
We trying to debug it now.
I've received message from kha0s, he successfully created the crashdump and we will analyze it 2-3 hours later. More info will be available later.

Title: Re: [ANN] NovaCoin - Balthazar's PPC + scrypt fork, pool list
Post by: Balthazar on April 07, 2013, 10:51:44 PM
Stratum is unavailable for NVC and PPC yet. It's because we use different transaction format and current mining software can't handle this correctly.

We have a plan to release modified stratum server for NVC and PPC, and stratum-mining-proxy with new transactions format support.

codegnome, it's just estimation. Real payments can differ from this value, and users are often receive payments while p2pool displays zero.

Host 127.0.0.1 and port 8336 for p2pool.

Simple p2pool guide for windows users:

Hi,

Is there somewhere a detailed guide on how to use p2pool with nvc?

The readme file attached was not helpful to me at all using the precomplied .exe.

Thanks,
balu
It's quite simple.

1) You need to run novacoin client in server mode, just like in case of solo mining. Create file novacoin.conf in

C:\Users\Your user name\AppData\Roaming\NovaCoin

with contents like this:

Quote
rpcuser=user
rpcpassword=password
server=1

2) Start client and wait for syncronization proccess
3) Double-click on run_p2pool.exe, wait until shares chain download will be completed
3) Point your miners to http://any_user:any_password@127.0.0.1:8336/

You are right, it does not. However no other gcc I could get my hands on could do this under mac osx.

Fortunately there is a solution and I was abale to compile it just fine. Use https://github.com/iongchun/cpuminer/blob/cpumine/nomacro.pl to expand the macros.

sudo perl nomacro.pl scrypt-x86_64.S

Already deployed new versions at khore pool.
After around 30 minutes runing:

- Decrease in Load Avg (from 0.5 to  ~ 0.25)
- Decrese in used memory (from 21 to 15%)
- And the best part: novacoind is now much more responsive when abusing from RPC calls  ;D

Will leave it under surveillance a couple of hours more, but from what I've seen: great work!

hi Balth,
you promiseed new p2pool somehwere like 2 weeks ago. We're still waiting:(

current p2p is too bigo for epople even with 7970 to earn ANYTHING and khorne has weird income calculation that looks like 40% tax:/

I would love to mine, but there is no way to do so!

It's because there are only ~240k coins available for operations. Emission is very slow.

Hi Balthazar what is the total number of unit that will be produced, i'm fairly new but understand proof of stake and proof of work also Scrypt, I'd like to help with market penetration I'm interested in NVC.

I noticed that NVC had a few haters on this forum , I just read the whole 21 pages.

I find NVC very interesting have you decided on a Symbol for it yet?

I come from that sort of background , i'd like to help , could we all try to develop one if this has not been done already?

Maximum coins volume is 2 billion, but real cap is non-deterministic.

I don't suppose someone knows how to fix this? I restarted my pc and went to fire up p2pool again and get this. I tried redownloading the block chain and deleted p2pool and tried a clean version and nothing is helping.

Looks okay to me. See where it says "Expected time to share: 2.0 hours"? You need to let it run for about 2 hours (on average) until you find a share and then you'll get paid.

The coin makes no sense, why is the difficulty so absurdly high with scrypt? Litecoin has yet to do 500. If it's because of Proof of Stake, how the heck do you even get coins with mining at this diff?

EDIT:Darn it, I was stupid. Looks like I was looking at "moneysupply" : 380696.09848900, and not the difficulty field...

Yes, you can. But first you need to unlock your wallet. You can't run p2pool or solo mining while your wallet is locked.

Run this command using RPC console:

Code:
walletpassphrase "password" 86400 true

This command will unlock mining for 24h, for example.

P.S. Are you sure you want solo mine at diff 96?  ???

I agree with Balthazar, 96 (scrypt) difficulty is much to high to solo with a couple of GPU.

If one was running a few rigs (Like myself), you would want to run a private Pushpool if soloing.

I run between 3-4 M/H for scrypt based coins, and my cutoff (My opinion of course.. :P) is low to mid teens for difficulty.

Find a good PPS pool, for whichever coin you want to mine.You will get the benefit of a definite payback, instead of risking getting nothing except a high electric bill when the difficulty is at the current level.

Is there a setting to unlock the wallet in the conf file, for mining via rpc for unlimited time? Also, I don't feel comfortable typing in the passphrase at the command line, and the OS also keeps a history of commands used.

Does novacoin-qt or novacoind support long poll? My cgminer returns "No suitable long poll found".

I guess I can use a liteoin hash calculator to estimate the expected time to find a block? I will use p2pool eventually. I am testing my setup for now.

I like Novacoin combing the advantages of LTC and PPC. Good job.

Thank you.

No, it doesn't supported yet, but maybe I'll add it soon. Anyway, you can set -s 10 -E 10 and everything will be OK.

Yes, also you can calculate it manually, using such formula:

Code:
T = Diff * 4.295 * 10 ^ 9 / HashesPerSecond

It will give you average block search time in seconds.

You can keep Linux from recording a command history by prepending one or more spaces  in front of the command.

Code:
./novacoind walletpassphrase iamapassword 100000

Would be recorded in the bash history.

Code:
    ./novacoind walletpassphrase iamapassword 100000

Would not be recorded in the bash history.

If you are using QT gui, you can use integrated console, it's safe enough.

Only if you have set HISTCONTROL with "ignorespace" which is not the default.

Edit: this is assuming you use bash and not another shell (I don't know others well enough).

Hmm, strange as it always appears to be the default to me.

For example from my current VM bash.rc file:

Code:
# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000

Ahh well, it is easy enough to test for:

Code:
robert@vm:/$ echo "This is normal"
This is normal
robert@vm:/$ echo "This is normal"
This is normal
robert@vm:/$    echo "This is hidden"
This is hidden
robert@vm:/$ echo "This is normal"

Well, anyway I believe this particular poster would feel much safer mining to a separate wallet (encrypted or otherwise) and just transferring the coins to his real wallet every day/hour whatever.  :D

Also:

Balthazar....what the heck did you do to bury the dam address version setting in your fork of ABE?

I have been trying all afternoon to get it set up and on CCE . I have tried all the normal places where the address version is declared, however no matter where I place (\x08 or 08..same in Dec as Hex) the addresses are wrong, everything else is right.

You just don't want anybody else to have a NVC explorer up....DO you?    :D :D

On that note: The newest version of ABE has some interesting new features you might want to check out. All the explorers except for NVC on CCE are using it. I did not feel like reinventing the wheel by converting your NVC fork to the latest ABE client.

Hopefully, I will have NVC up on CCE tonite, everything is set and ready except for the address version issue...thing...roadblock... :P

I'll try to merge it with latest code, if it's necessary. Will check it tomorrow. ::)

P.S. I seen strange glitch... It forces bitcoin address version while browsing orphaned blocks.
P.P.S. Don't use integrated web server, it's too slow. It is recommended to use apache2-mpm-event + fcgid + ABE running in fastcgi mode. It will be more reliable solution.

I changed over to Fastcgi the weekend of the big coin rally a month..two months ago??? I had been wanting to convert all the explorers to Cherry.py, but during that rally felt I did not have the luxury of time to do it. I went ahead and converted everything to Fastcgi, and believe me, it can have its own set of problems... :D

But yes, it is a 110% improvement over pythons built in server.

*It will neutralize benefit of early adopters, and will make system even more stable against dump attempts.

There is no re-target interval. So, it's very hard to predict the difficulty in the future, if hashrate is unknown. You can only estimate difficulty for the next block.

Hi all. I asked my friends to publish 0.4.1 and 0.4.1 builds while I'm at hospital.

I'll publish the full changelog later, important changes are listed below.

  • Dynamic PoS interest. Now it's a function of PoS difficulty, nRewardCoinYear = 1 / (posdiff ^ 1/6). It can have values from 100% to 1%;
  • Checkpoints ignore option added, disabled by default;
  • Bug fix for coinstake transactions display in QT client;
  • Bug fix for AvailableCoins function, prevents immature coins usage;
  • Mac OS X compatibility issues resolved, from now we publishing official Mac OS X 64 bit builds also;
  • New genesis block for testnet.

Update should be performed before 20 June 2013.

Minimal PoS difficulty is hard coded to 0.001. So, at 0.025 PoS difficulty you will get 1 / (0.025/0.001) ^ 1/6 = 0.59 coins per coin-year, i.e. 59% year interest.

Hi all. I asked my friends to publish 0.4.1 and 0.4.1 builds while I'm at hospital.

I'll publish the full changelog later, important changes are listed below.

  • Dynamic PoS interest. Now it's a function of PoS difficulty, nRewardCoinYear = 1 / (posdiff ^ 1/6). It can have values from 100% to 1%;
  • Checkpoints ignore option added, disabled by default;
  • Bug fix for coinstake transactions display in QT client;
  • Bug fix for AvailableCoins function, prevents immature coins usage;
  • Mac OS X compatibility issues resolved, from now we publishing official Mac OS X 64 bit builds also;
  • New genesis block for testnet.

Update should be performed before 20 June 2013.

So the expected reward will go down to 1.83% a year based on 0.025 PoS difficulty?
Minimal PoS difficulty is hard coded to 0.001. So, at 0.025 PoS difficulty you will get 1 / (0.025/0.001) ^ 1/6 = 0.59 coins per coin-year, i.e. 59% year interest.


I like it.  :)
When will this change go into effect? As soon as I upgrade to 0.4.1, or when more than 50% of clients have upgraded to 0.4.1, or on 20 June 2013?

Change will get power on 20 June 2013. When 50% of clients will be updated, old client users will receive warning. If they ignore it, they will stay on forked chain.

How can I find out how many coins I've mined through proof of stake? All I've seen is that some of my coins where moved to stake and then back to my balance after a while. I think this should be reported better now that there's some significant interest to be gained from PoS.

Mined coins volume displayed on transactions list page, something like this:

03.05.2013 06:14 Mined [unknown] [+3.14]

P.S. You need 0.4.1 client to see this. Also I think about "stakegeneration" field addition to getinfo rpc call result.

Yes, if it will be required to make system more reliable. Dynamic interest adjustment is better than static interest, and it has economical sense.

0.4.2 update is ready and will be published in next 24h.

It includes a few changes in addition to new PoS ROI calculation algorithm, which was implemented in 0.4.1:

  • Fix for lk_max_locks exhaustion problem, more info is available here (http://bitcoin.org/may15.html). It will become active since 20 Aug 2013;
  • 27 bits PoS target limit will become active since 20 Jul 2013.

Whats the difference between a fork and a clone?

A fork happens when substantial changes are made to the source code that make the new version incompatible with the old one. A clone is when somebody takes the source code and makes little or no modifications and starts a new coin with it.

Repository updated, builds published.

Builds: https://sourceforge.net/projects/novacoin/files
Source: https://github.com/CryptoManiac/novacoin

Protocol update conditions:

0.4.1 and 0.4.2 will be compatible with 0.3.5/0.4.0 until 20 June 2013.
0.4.2 will be compatible with 0.4.1 until 20 July 2013.

An optimal way is update to 0.4.2 before 20 June 2013.

Forked from TheSeven's repository and added nvc-specific changes. It should work, but wasn't tested yet.

It works for own p2pool nodes, but there is no support for cooperative mining nodes yet. The fix is quite simple, but actually, we prefer the network of many "small" p2pool nodes instead of the big one.

Anyway, it seems that we have no choice, because some users already need it. :) So, new p2pool version will be published as soon as work under StratumServer will be completed.

Changes list announce:

  • Shares difficulty selection, by using difficulty ratio as password;
  • New blocks version schema support;
  • Cooperative mining nodes support.

How is NovaCoin PoS different from PPCoin?
(sorry, but I generally find so little info on both PoS)
Actually, there are not so many differences. The main differences are dynamic ROI calculation and another entropy bit source.

3. Novacoin will give me aids and kill all my family..

I've been mining russianmafiacoin steadily for a few weeks now and will continue to do so.  If you really pay attention to coinchoose.com it is actually the most stable and consistently profitable coin with a reasonable difficulty (not like litecoin or bitcoin).  I was chasing around the newest/most profitable coins for a while but I think it is a waste of time and hashes.

0.4.3 minor release planned for this weekend. Changes announce:

  • GBT speedup up to 10 times, to make stratum pools more reliable under high tx/s rates;
  • Stake generation statistics (available coins amount, current stake generation power) will be available through RPC;
  • Coinstake inputs adding policy will be a little more aggressive for some cases.

0.4.3 will be compatible with 0.4.2 in terms of database format and protocol rules.

Way to go! That sounds like it will make Proof of Stake mining more like "real" mining. Adjustable difficulty means that the difficulty will go up and down and therefore a PoS miner would like to be able to control when to release his coins for mining. Is this what you mean?

The fee is set at 0.01 per KB. So probably your transaction has many inputs and therefore costs more to process.

According to currently online peer stats, 25% of online nodes upgraded to 0.4.2. Mining and stake nodes are almost all already running 0.4.2 (~100%). So, there is no chain fork possibility. :)

But if you are <=0.4.1 user, you need to apply the latest version update before dates, which are listed below.

  • 18 days remaining to PoS ROI calculation switch. Starting from 20 June 2013 clients older than 0.4.1 no longer will be compatible with the main network.

According to currently online peer stats, 25% of online nodes upgraded to 0.4.2. Mining and stake nodes are almost all already running 0.4.2 (~100%). So, there is no chain fork possibility. :)

But if you are <=0.4.1 user, you need to apply the latest version update before dates, which are listed below.

  • 18 days remaining to PoS ROI calculation switch. Starting from 20 June 2013 clients older than 0.4.1 no longer will be compatible with the main network.
  • 48 days remaining to PoW spacing switch. Starting from 20 July 2013 clients older than 0.4.2 no longer will be compatible with the main network.


I just got the latest client -

are you basically just saying update the client ?

also with the nvc.khore.org pool , does the payout come all in a bunch - most other pools i've been on when they find a block you get a fraction - i've been on it for hours with 0 in the account ?

yet i'm there on the pool stats - @ 7th in rank. on #.

Yes, I'm talking about upgrade. There is nothing to do if you are already on 0.4.2.

nvc.khore.org uses PPLNS system, it pays only from found blocks.

NVC P2Pool currently has no support for cooperative nodes, all payments will be performed only to your wallet. To prevent obvious questions you need to stop your node before there are any payouts done. New P2Pool with cooperative nodes support will be started two days later from the "fresh list", with the new shares chain.

By coincidence, I implemented mining to worker's address just a couple of days before (with your p2pool code). It has been running fine for 2 or 3 days in Bitbar network (which is NVC clone), finding blocks and paying out to miners. The patch is about 20 lines of awful hack-shit-code, but it works! To mine on a public node running this code, miner has to specify NVC public key (not an address!) as its username. Changes go down to this:

Protocol update: Preconditions and prospects.

Just like PPCoin, NovaCoin uses ChainTrust score instead of ChainWork (used by BTC, LTC and another PoW-based systems).

We decided to implement the new chain trust score calculation algorithm. It will prevent pure PoS double-spend attacks even without broadcasted checkpoints. Now I'll try to describe, how it works in comparison with an old algorithm.

Old chain trust score calculation algorithm basics:

1) PoW block always adds 1 to current chain trust score;
2) PoS block adds (CBigNum(1)<<256) / (bnTarget+1) to chain trust score.

Result: we have dictatorship, stakeholders are Gods here.

Benefits: It's impossible to perform PoW-based double-spend or DoS attack.
Flaws:

  • Owner of enough stake weight (25% of total weight or more) able to perform PoS-based double-spend or DoS.
  • Double-spend could be prevented by broadcasted checkpointing.

New chain trust score calculation algorithm will be more complicated. Here is the concept (1/3 and 2/3 are parts of example, final ratio values can differ from this):

1) PoS block adds (CBigNum(1)<<256) / (bnTarget+1) to the total chain trust score only if it has PoW block as parent;
2) PoS block adds only 1/3 of "usual" PoS block trust score if it has PoS block as parent;
3) PoW block adds (CBigNum(1)<<256) / (bnPrevBlockTarget+1) to the total chain trust score, if it has PoS block as parent;
4) PoW block adds 2/3 of previous block trust score to the total chain trust score, if it has PoW block as parent.

Result: Hybrid chain always has higher trust score than pure PoW or pure PoS chain.

Benefits: It's impossible to perform pure PoW or PoS-based double-spend. DoS-like attack scenario is also impossible in such cases. Attacker must combine enough PoW & PoS generation power to get success.

Flaws:
  • System will become slightly less energy efficient. But still more efficient than PoW-based system.
  • ???

According to release plan, new algorithm will be introduced in 0.4.3, but will be inactive on the main network until 20 Sep 2013.  ::)

I should note that it's highly recommended to set fee if you are running the public p2pool node (see --fee parameter description). Zero fee at public node introduces a chance to generate invalid block.

Update: Yep - followed the same steps as I do for PPC and it unlocked for minting...

Make a .bat in your daemon folder. Name it novacoind.bat Paste this text save and close.

@echo off
@echo Enter Novacoin password...
SET /P variable=Password :
novacoind walletpassphrase %variable% 9999999 true

Start up your encrypted wallet and run the .bat.

Enter your password, Window will pause then exit. Your wallet in now unlocked.

EDIT: Ahh i see you got it. Maybe this will help someone else with the same question.

Netstakeweight is an estimation of total active stakeholders weight (in coin*day units), stakepower is your own stake weight. Stakepower field will be renamed to stakeweight in 0.4.4.

Also, where's the proof-of-stake difficulty?
getdifficulty RPC call returns an object

It contains PoW and PoS difficulty fields. But I think that this also should be added to getmininginfo output. ::)

You can see here how many times the clients have been downloaded:

http://sourceforge.net/projects/novacoin/files/

That's probably the best estimate about how many users there are.

Novacoin is the perfect coin for hoarders because it pays interest. I wouldn't dream of tipping novacoins just like I wouldn't tip gold coins.  ;D

Unfortunately, we can't see statistics for removed files (old releases). ::)

Currently the most part of users are investors, miners and some merchants owned by enthusiasts. Because there are not so many coins generated yet. But this will change when the mined volume will grow enough to allow higher capitalization.

Have you checked that page? I only see 300 downloads on it.

What do you think the real number is? NVC is the most mysterious out of all the coins... it's high value, it's stability, it's general lack of interest on here. Weird.

Thank you Balthazar for your work on NVC, with the time im slowly moving to NVC, since p2pool+nvc work well its the time to move 24x 1GH, sorry pool operator but no thx i will not mine for you.

P2Pool currently works well, that's true. But there is a plan to restart p2pool shares chain after 20 Sep 2013.

New NVC protocol changes will be activated since this date, allowing us to remove ECDSA signatures for PoW blocks and 0.01 coin lower bound for coinbase outputs. So, P2Pool diff with upstream will become significantly smaller than diff of current P2Pool implementation. Also it will provide an opportunity to run public nodes without current limitations.

Hi all. I asked my friends to publish 0.4.1 and 0.4.1 builds while I'm at hospital.

I'll publish the full changelog later, important changes are listed below.

  • Dynamic PoS interest. Now it's a function of PoS difficulty, nRewardCoinYear = 1 / (posdiff ^ 1/6). It can have values from 100% to 1%;
  • Checkpoints ignore option added, disabled by default;
  • Bug fix for coinstake transactions display in QT client;
  • Bug fix for AvailableCoins function, prevents immature coins usage;
  • Mac OS X compatibility issues resolved, from now we publishing official Mac OS X 64 bit builds also;
  • New genesis block for testnet.

Update should be performed before 20 June 2013.

So the expected reward will go down to 1.83% a year based on 0.025 PoS difficulty?
Minimal PoS difficulty is hard coded to 0.001. So, at 0.025 PoS difficulty you will get 1 / (0.025/0.001) ^ 1/6 = 0.59 coins per coin-year, i.e. 59% year interest.

Yes, it's high at the moment but I think it will go down fairly quickly as the difficulty rises.

Yes, it's high at the moment but I think it will go down fairly quickly as the difficulty rises.

Not really.. if the difficulty shot up from 0.04 all the way to say 40 then the interest rate would still be:

1 / (40/0.001) ^ 1/6 = 17.09%

It depends on what a reasonable range for d is.. but the 1/6 power really keeps the changes slow.


Title: Re: [ANN] NovaCoin - Balthazar's PPC + scrypt fork, pool list
Post by: Balthazar on June 29, 2013, 02:09:48 PM
PoS emission will cause the slow raising of total network stake weight. Higher network stake weight will cause higher difficulty and lower interest. But maybe we will change power to 1/4 before protocol freeze, will see later.

P.S. Current PoS difficulty is 3.8 in PPCoin, for example.

It's impossible to predict with certainty what will happen to the difficulty. Having said that, I don't think that the difficulty will rise linearly. My guess is that it will rise exponentially, but I could be wrong!

I think it scales with the number of users who are mining on full nodes (and the amount of stake they are mining with). It may not scale that fast and as the hardware demands of running a full node increase it may even start to drop at some point.

Payouts every half hour, seems fair and no problems so far.

Could be best for new/small miners

Is there a lending website for NVC or place that pays savers

How do I use a P-O-S?  Does it require any special actions?

Hello!

To generate blocks with POS, you must have inputs bigger than 1 NVC and older than 30 days. Probability of block generation (per second) is
Code:
Sum_coins * (Age_days - 30) / (2^32 * POS_diff)

Reward per coinyear is
Code:
(0.03125 / POS_diff)^(1/6) coins

Note that when calculating reward, the coinage is rounded to integer coinyears. That means that if you have input of 10 coins and find a block on 35th day of its age, you will be rewarded for 0.96 coinyears, which rounds to zero.

Hi there, if i have 10 NVC for a week, then i constantly mine a few and send them (only whats mined) to another wallet for two months, will those first 10 blocks count towards POS generation during that time?

Yes, if this transactions will be more than 30 days old. Only transactions with age greater than 30 days could be used for proof-of-stake blocks generation.

P.S. Mac OS X build published, need some testing.

minweight - weight of inputs aged from 30 to 90 days;
maxweight - weight of inputs which are more than 90 days old;
passiveweight - weight of inputs which has age lower than 30 days.

Quote
There also seems to be a bug because my client reports this
It's not a bug, it's a real value (1 coin per coin*year now). This caused by two events:

  • Minimum PoS difficulty was changed to 0.031 in v0.4.2 client;
  • BTC-e burned available coindays in their wallets by sending all deposits to local address, and switched off the stakes generation feature. We asked BTC-e to perform this action, in order to make network more decentralized. As the result, PoS difficulty went down.

This will be normalized in a next few months.

P.S. 0.4.4pre seems quite stable, so release scheduled for this sunday. In addition to published changes it also will include upper limit for coinstake reward (will be calculated using linear function of PoW reward).

That's a good idea, but you must tell us what the upper limit is (not everybody is a programmer).

Sorry, it still doesn't make sense to me. Please explain the meaning of stakeinterest.
The stakeinterest field represents reward for 365 coin*days in satoshi units. I.e. 1000000  value means that you can get 1 NVC (1000000 of satoshis) reward in case if you have

  • 1 NVC output with 365 days age
  • 10 NVC output with 36.5 days age
  • etc

That's a good idea, but you must tell us what the upper limit is (not everybody is a programmer).
It's not ready yet, that's why there is no full explanation at the moment, but it's quite simple. Just one example, if you have two options:

  • 1000 coins input
  • 10 x 100 coins inputs

there will be no difference in profitability, which is wrong.

Smaller inputs should be prioritized, because it's significantly better for the network, that's why we need this upper limit for the reward. To make sure that there will be no malicious stakeholders, which are able to manipulate by PoS difficulty through using larger inputs instead of smaller ones.

Important addition: if you are using win32 installer then make sure that 0.4.4pre was removed before 0.4.4 release installation. It's required because installer will not update 0.4.4pre files automatically.

From this release we'll apply new version numbering scheme in order to prevent such problems in the future.

X.Y.Z

  • Odd value for Y and Z reserved for unstable branches/releases;
  • Even values means stable branches/releases.

E.g. 0.5.x will be unstable branch, 0.4.5 will be experimental release.

nTimeWeight calculation

Originally it was planned to start nTimeWeight from zero at the 30-day min age. This should increase active coins participating the hash and provide additional security when proof-of-stake difficulty is low.

Anyway, this feature is disabled for now and needs some discussion.

v0.4.4.1

  • DNS seeding is enabled now;
  • Timestamp field added into checkpoints table;
  • Skip header signature checking while connecting a block (it's safe because ProcessBlock still performs signatures checking);
  • Skip PoW header ECDSA signatures validation since block #9689 until the last checkpoint.

This should make synchronization process slightly faster.

** You can use -derivationmethod option to choose which method will be used for wallet encryption keys generation.

Possible values:

  • sha512 - default value, compatible with bitcoin;
  • scrypt+sha512 - selects scrypt derivation function.

Please note that this option only allows you to select default method for the new encrypted keys. If you are already using encrypted wallet then suitable derivation method will be selected automatically.

Currently we are working on LevelDB support, source tree will be updated soon. Testing snapshot is quite unstable, but syncronizes well enough.

LevelDB minimizes memory usage and makes syncronization faster, but there is also some Proof-of-Stake related side effects. E.g. validation of PoS block requires additional LevelDB transactions. As the result, performance benefits are lower than it would be for pure PoW based system. ::)

// UPDATE: merged (https://github.com/CryptoManiac/novacoin/commit/adb8391acdf671640adb1e8be564e68b254fca69) into the main tree. Testers are welcome. :)
// UPDATE2: memory leak found, thanks for the report

Hi everyone.

KHORE pool is now running on a brand new server. We more than doubled the resources available to pool, so expect extra performance! :)
Due to the downtime caused by the switch to new server, I'm offering 48 hours with 0% fee.

Minor client update is available.

v0.4.4.4

  • Google's LevelDB support is implemented, and used as transaction storage by default*;
  • The -nosynccheckpoints option is replaced with the new -cppolicy=mode option**;
  • RPC: blocktrust and chaintrust fields added into block dump function;
  • Many minor fixes and optimizations.

*) LevelDB is a low-latency data storage, optimized for multiple write operations. DB engine works in a separate thread, this also could improve wallet performance.

**) Possible values:

  • strict - default mode, verify blocks to satisfy syncronized checkpoints, and reject if necessary;
  • advisory - verify blocks to satisfy syncronized checkpoints, and display warning if necessary;
  • permissive - don't perform any checkings.

That's a good idea, but you must tell us what the upper limit is (not everybody is a programmer).
It's not ready yet, that's why there is no full explanation at the moment, but it's quite simple. Just one example, if you have two options:

  • 1000 coins input
  • 10 x 100 coins inputs

there will be no difference in profitability, which is wrong.

Smaller inputs should be prioritized, because it's significantly better for the network, that's why we need this upper limit for the reward. To make sure that there will be no malicious stakeholders, which are able to manipulate by PoS difficulty through using larger inputs instead of smaller ones.

Have you decided yet what the upper limit is?

Have you decided yet what the upper limit is?
This limit is set to 10 coins, but inactive until 20 Oct 2013. According to result of our analysis (and independent results too), it's an optimal value.

But we are also working on alternate solution. It's a dynamic computation of the reward limit, based on PoW difficulty. Maybe this function will replace a static limit in the future, but I don't think so.

People need to wake up and realize zerocoin implementation will invite increased legal scrutiny, especially from the US.  And that there is a chance some businesses, and most likely in the financial services industry, will close their doors to a digital currency with full anonymity.  Zerocoin is not all a good thing.  There are risks...

Absolutely, but it's a matter of principle. Anonymity should have been built into Bitcoin from the very beginning, just like e-mail should have been encrypted from the very beginning. I'm not a criminal, I just don't want everybody to be able to read my emails and scrutinize my finances. Criminals already know how to maintain their anonymity with cryptocoins, and the biggest of them even use the banking system to launder their money. Anonymity should be the norm, a human right, not something to be afraid about. If ZeroCoin scares you then sell your NVC.

People need to wake up and realize zerocoin implementation will invite increased legal scrutiny, especially from the US.  And that there is a chance some businesses, and most likely in the financial services industry, will close their doors to a digital currency with full anonymity.  Zerocoin is not all a good thing.  There are risks...

yes, I agree.  What I'm saying is those institutions imposing the regulatory measures won't just go down without a fight...the first coin to implement zerocoin could very well end up being the sacrificial lamb.  This is what I meant when I said there are risks.  I think the Bitcoin Foundation knows this and that's why they've not made zerocoin implementation a priority.

It's not a priority for us too. Just another feature, which planned to be implemented. I don't think that ZeroCoin will be available in the production network at this year, it needs the prolonged testing on the testnet. Because it's too new technology for implementing in the production network. By the way, I already found and fixed some small issues in the original libzerocoin code.

9 days remaining to protocol switch (20.09.2013).

The following limitations will be removed:

  • PoW blocks ECDSA signature;
  • 0.01 NVC outpoint value limit for coinbase transaction;
  • Stake rewards truncation, caused by integer division.

You only need to put your coins in your wallet and wait that they mature 30 days there. For a PoS block generation your wallet must be running and unlocked (after the 30 days).
Don't use an exchange wallet. No exchange will reward you with PoS (at least that I know off).

But from October 20 the maximum PoS block reward will be 10 coins. I.e. inputs like this (http://nvc.cryptocoinexplorer.com/block/61072434afc597a029719ea9e63cdd0bdec36a01ac984f5b9daf71115564bf5d) will generate 10 coins instead of 100+.

Rewards are calculated from inputs size, not from the wallet balance. You can have the same sum using completely different inputs set, 1x600/2x300/4x100+1x200/etc. Inputs could be listed using listunspent RPC command.

http://s019.radikal.ru/i627/1309/f6/de11912caa11.png

If you have one 600 coins input, then you can split it into into inputs set by sending it to multiple local addresses. Just create some addresses and send your coins to them.

You shouldn't do any thing to "set up" PoS mining, because it works by default and there is no option to disable it. Except for encryption of wallet or reservebalance option in the config file.

MinWG64 adapted branch published:

https://github.com/CryptoManiac/novacoin/commits/novacoin-win64

There are some OutputDebugStringF related warnings yet, will deal with it later.

P.S. Thinking about the ZeroCoin integration.  ::)

That's cool. We are too. But are you aware of the technical issues here? If you wish a "anonymizer" in your chainblock. Wee're working on another "anonymizer" implementation as well. This will not require changes to the chainblock, but would require all users to download a updated wallet. If you would like to discuss it more please PM me.


DigitalHermit did a great job highlighting the biggest flaw with the implementations yet.

FYI:

how far is your zerocoin implementation?

Was just coming here to ask the same thing. Any updates?

It's still in an early stage. The first part will be implementing the early alpha of Zerocoin into the Anoncoin testnet, then comes the testing to discover bugs within Zerocoin itself that the Zerocoin devs will be working on. I would not expect a fully working zerocoin implementation until the end of the year at best. If it works flawlessly the first time around (personally I believe there's a ~1% chance of that happening) it would probably be complete during november.

Are you integrating the Zerocoin v1 library as is or do you have plans to deal with the two major flaws in Zerocoin first, before releasing it for use against the "production" AnonCoin blockchain?

Flaw #1: Zerocoin v1 is highly inefficient (not production ready).

https://github.com/Zerocoin/libzerocoin/wiki/Frequently-asked-questions
Quote
The current implementation of Zerocoin has two efficiency problems. First, the 'coin spend' zero knowledge proofs are somewhat large (>25 KB). We intend for these proofs to reside in the block chain, but their large size makes this challenging. As a result it may be necessary to distribute them via some other mechanism such as a Distributed Hash Table.

Additionally, Zerocoin spend proofs are somewhat time consuming to verify, at least as compared to ECDSA signatures (they take a larger fraction of a second). This creates problems with latency when all nodes verify them, though we are hopeful that there are engineering solutions to this problem.

We are currently working on improvements to the Zerocoin cryptography that we hope will bring smaller and faster proofs. At this point we will release a 'Zerocoin v2' protocol and users will have to decide if they want to deploy this protocol in their networks.

Flaw #2: Zerocoin as currently implemented requires configuration with a trusted non-secret integer of 1,026 bits in length generated by multiplying together two factors p and q. That means you need a "trusted party" to configure Zerocoin; more importantly, if this trusted party decides to hold on to the p and q factors they used (rather than destroying them) or shares them with anybody, then they will be able to double spend any zerocoins. This is a fatal flaw if we wish Zerocoin to operate in a zero-trust manner.

https://github.com/Zerocoin/libzerocoin/wiki/Generating-Zerocoin-parameters

Quote
Security Warning: It is critical that the modulus N be generated properly and that the factors p, q and all related information be destroyed. These factors are not needed in the protocol. Moreover, any party who learns these factors will be able to double-spend zerocoins. Note however that knowledge of p, q does not jeopardize the anonymity of Zerocoin.

...

A second project (not currently planned) is to implement distributed multiparty generation of the modulus N. Some protocols exist in the literature to do this. We are not aware of any that have been implemented.

If you plan on integrating Zerocoin as is, that's fine. I just hope you realize that by doing so you'll be turning the AnonCoin blockchain into more of a test/research blockchain that may not scale well (due to Flaw 1) and can't be fully trusted (due to Flaw 2).

Hey!

I really believe in NVC and try to get our mining pool at coinEX running.
We have found 5 blocks already, but we still need more hash. We would be glad if someone could join us and help us.
I have all my rigs pointed to this pool for the next months, so together we can do it  :P

https://coinex.pw/mining/pools/NVC

I will pay the next 5 blockfinders an extra nvc  ;)

That's correct, ZeroCoin isn't ready for production yet. That's why it will be available for the testnet only.

It's not a serious problem for the real-life scenario. Nobody will hold such information, it's too risky for health. Especially if you are a public person, like me. Destroying is a preferred solution, in terms of safety. There is no thing which could be used to pay for p and q holding related risks.

Ok  :) And you're aware of that the 'coin spend' zero knowledge proofs are somewhat large (>25 KB). That means it's too large for the block chain itself, and the client must have a DHT network or something in that area as well for distributing those. Have you found any good libraries?  :)

I'm on the hunt myself!

DHT usage is too risky option, because it adds a point of failure into the system.

In my tests resulting proof sizes vary from 23 to 26kb. This could be handled by using the following approach:

1) Introduce the 520 blocks maturity window for coinspend transactions;
2) Include ZeroCoin transactions into Proof-of-Work blocks only;
3) Implement spent outpoints removal option (similar to "Ultraprune" branch, which merged into bitcoin 0.8.x);
3) Use gzip/bzip2/lzma/whatever in-memory binary compression in combination with standard 0.01/1kb fee.

But we still got a problem since the zerocoin library isn't a fully implementation of the zerocoin extension AFAIK.

Yes, but available functionality is enough for transactions validation. There are only a few issues with accumulatorblockhash/transactionhash, which implemented in the constructors, but actually not used by the library.

New p2pool release is planned for this weekend. It will start an independent shares chain due to some incompatible changes.

  • Fee for coinbase isn't required since 20 Sep 2013, so this code will be removed;
  • ECDSA signature isn't required for PoW blocks since 20 Sep 2013. This allows us to remove a few serious limitations, such as requirements for public node fee and wallet unlocking;
  • -a option support, wallet address as worker name support;
  • No truncation for rewards lower than 0.01 coin;
  • 15s shares target spacing.

After 30 days you have A LOT of coindays, but still no stake power, it just started building up. With 1k coins input it shouldn't be to long.
Run your client after few days, unlock the wallet, and you should get a block quite quickly.

nTimeWeight calculation

Originally it was planned to start nTimeWeight from zero at the 30-day min age. This should increase active coins participating the hash and provide additional security when proof-of-stake difficulty is low.

Anyway, this feature is disabled for now and needs some discussion.

https://github.com/CryptoManiac/novacoin/commit/b9289ef1acf9c6c6146c573955443f555abb9351

It's planned to enable this since 1 Jan 2014 if there will be no negative effects discovered.

Hi Balthazar,
I would like to congratulate you on a the implementation of the coin control Feature,
I think it's what was missing, and even though I did not yet use it for creating an actual Transaction,
I played around with it a bit, and yep... that's what we have needed :-)

regarding the nTimeWeight changes I talked to a few People who are dedicated fans of NovaCoin (as I too have become) and the Consensus is quite clear: we think it's a bad idea.
I would probably do something along These lines if it were activated:
Put Money into a wallet, and then take it offline for half a year or longer before taking it back online for PoS Generation, to not "risk" having a PoS after 40 days for which you get only paid for 10 days, i.e. only 25% of the actual Holding time.

I'm Aware that this is not in the interest of the network, so I'm heavily against it - imo the strength in NVC is for storing value with inbuilt hedge against coin Devaluation thanks to PoS. And the recent strength (in NVC/USD) during the recent Price rise in btc/usd Shows this quite well, seeing how most other coins took heavy losses in that time.

Kind regards
Mike

Rewards are calculated from actual age and there are no plans to change it. nTimeWeight isn't used for rewards calculation, this variable is used for kernel hashes target calculation only and doesn't affect rewards.

Congratulations from me too, but it's still a little buggy. I did create a transaction and I noticed that the actual fee was half than what Coin Control said it would be.
Coin Control is experimental feature and isn't quite ready for production yet... 0.4.4.5 will be released in the next few weeks, this release will include some serious CC fixes.

Kernel hash checking is performed using this condition:

hash(kernel) <= bnTarget * nValue * nTimeWeight

If nTimeWeight starts from zero, then immediate block generation will be prevented even with extremely low difficulty.

This feature is active from being of time startup of chain, but the TimeWeight is limited by 60 days (https://github.com/CryptoManiac/novacoin/blob/master/src/kernel.cpp#L297), which is wrong. This will be fixed since 1 January 2014 (https://github.com/CryptoManiac/novacoin/blob/master/src/kernel.cpp#L292).

Thanks for the Explanation - now I can also see it in the source :-)
So nTimeweight would be higher than now from coin-age day 90 on onwards, so basically smaller amounts of NVC that took more than 90 days before the change would generate PoS faster, right? (assuming same PoS difficulty as right now, I guess it might adjust a bit after the switch)

Thanks!

Hi,

is there some way to create a printable passphrase-protected private key like you can do on http://www.bit2factor.org/ for Bitcoin private keys?
That site refuses a novacoin private key as Input, not sure if just patching out a check would work but would prefer having a better solution than that :-)
Then I could have it printed on, say, a coffee mug that I Keep in the Office in case my flat burns down to the grounds :-)

Thanks!
Mike

I was using a recent cgminer with fsb p2pool. One of the nice things of the recent developments (post 3.6.6) in git with cgminer was the stats were revamped to work correctly with low share difficulty, so that I was finally seeing shares greater than 0. Then some changes were done in the 3.7 line so that I was getting 100% false positive HW errors. I filed a bug report in the cgminer thread here only to be told by Con Kolivas that GPU and Scrypt support was being dropped from cgminer.  :-[ Needless to say I was irritated, but arguing with BitCoin fanboys was futile; the git tree was quickly updated to remove all support for GPU and Scrypt.

I am quite disappointed, but wanted to know if there are any better alternatives for mining Novacoin? I hear that reaper is no longer maintained.

Explorers at novacoin.ru & novacoin.su will be shut down in the near future, because we don't need so much explorers. We already have http://nvc.cryptocoinexplorer.com and http://explorer.novaco.in, I guess that's enough for our purposes.

http://nvc.cryptocoinexplorer.com is currently stuck at block 55673.

Only http://novacoin.ru/ appears to be working at the moment and is already at block 55756. Maybe it's a good idea to have more than two block explorers?  ::)

It seems that CCE explorer has a problem with syncronization, I guess their daemon is currently down. In the meantime, novaco.in explorer engine is currently under active development, so it still has some issues with database, I think this will be fixed soon.

So, maybe you are right and we need to keep "standard" ABE explorer at novacoin.ru for this time. ::)

You can get it from novacoind with the getmininginfo call. It currently returns 710000 satoshis per year for one NVC, which is 71%. Alternatively you can use this formula: 1 / (0.08658/0.031) ^ 1/3 = 0.71 which also means 71%. In this formula 0.08658 is the current PoS difficulty.

Anyone know the answer to this :  does encrypting your wallet (putting a passphrase on it) end all your PoS minting irretrievably?

Like say hypothetically some guy was trying to mint pos blocks, and he waited 20 days with nvc in his wallet, then he put a password on the wallet, is all the minting contributions / pos work lost?  I -- errhhh--- I mean some guy were to remove the password immediately after putting it on his wallet, would it just resume where it left of regarding PoS minting, or would all the work be lost ?

when you open wallet without password after 30 days you will mine POS block - dont worry. Now you should focus how to unlock your wallet.

There's no 'work', the client just tries different hashes until one of them satisfies the target. It's more like regular mining.
So you only need to unlock your wallet and wait until the block is found.

nvc.cryptocoinexplorer.com is back in sync. One of the issues I have run into over the time I have been running cryptocoinexplorer.com are coin daemon crashes. This is not just a Novacoin issue, but seems to plague all the coin daemons. ABE itself has no real way to detect if a daemon has crashed and attempt to restart it.
I will be attempting to instill this ability in CCE3. However, I have having an issue with DB connections vs. user threads in the web server that needs to be addressed first. The database loader is working perfectly now and I will probably add the ability to check/restart coins daemons in that module.

Dumb people have been saying this since it came out, yes it was pre-mined, but it's actively developed and has been consistently more profitable to mine than Litecoin. Only recently has Litecoin been much more profitable, and that just changed with the bump in NVC price.

Bitch and complain all you want about it being a scam coin, but if you put an identical amount of hash power on LTC and NVC 6 months ago, your pile of NVC will be a lot bigger and worth a lot more.

Novacoin has some good fundamentals. I thought it was much undervalued last week. It always traditionally was around 0.02 or at least more than LTC so glad to see it come back to it's position.  Though ya, the spike and height it has reached from the recent boom is certainly surprising.  I was guessing more along the lines of 10-15$ but hey, the market wants lots of Novacoins.

Novacoin has no fundamentals. It has no market, no volume, no demand. It offers no innovation. The only thing it has going for it is that the half dozen Russians that premined it own 95% of all the coins and collude to control the price. If you're not one of them and you choose to own this coin, then you're a fool.

And the market does not want lots of Novacoins. The order books are completely bare. The scammers just sell the coins to themselves making it look like there's demand to sucker in the noobs.

Wrong again. Novacoin has low volume because most people mine it for proof-of-stake instead of trying to make money by trading it. The recent price rise is because people want to diversify out of Bitcoin. Most altcoins have risen and Novacoin is no exception.

Where you going for sarcasm here ? I'd be surprised if it was by pure accident or not any knowing better that each point you made is incorrect.

1)NVC has a market cap of over $11 million now.
2) NVC has a normal volume traded considering it is a savings-encouraging coin.
3) There is demand for it. If you think the owner of BTC-E is buying his own NVC at increasingly higher rates to increase the price, well, your gonna need some sort of evidence beyond just your idle speculation.  Are you also ignoring that NVC is traded on 6 exchanges? Sure most of the volume is on BTC-E, but do you think Vircurex and Crypsty are in this Novacoin conspiracy?
4) NVC is an innovative mix of scrypt/pos/pow. It is one of the older, more original alt's. NVC has itself been copied hasn't it, into Bitbar (don't quote me on that).  
4) Premined coins were destroyed. 95% is wildly inaccurate.
5) I've been mining NVC for many months with my remaining 2 gpu's I kept and bought a couple dozen NVC when it was 3.50.  Am I a fool?  
6) You can not seriously suppose that 'scammers' are doing all the trading with themselves, driving the prices, that is silly. And hey sure may even a big pump and dump right now going from 5 to 20. But people trade coins in the open market and the market is liking NvC, and that is why it is at the price it is, simple as that.

Sorry guys,  guess I shouldn't feed the trolls....

No there are sadly dozens of altcoins with that combination, though NVC is probably the first, this hardly count as innovation; these features are taken from other altcoins.

Here's my humble opinion: I like to think of Novacoin as Bitcoin, Litecoin and PPcoin done right. Each of those coins does something right, but only Novacoin does everything right.  :D

The only thing I see is the half dozen kids suffering from extreme butt hurt, and nothing more.

By the way, the uncovering of own nationality would be logical. Of course, if this really matters for you.

The scammers just sell the coins to themselves making it look like there's demand to sucker in the noobs.
Try again better, and may be you'll be able to buy some cheap NVC. If I am wrong here and you are not a dump scammer but truly believer, then try to join the Flat Earth Society. It is obvious that your joining request would be accepted without any problem, they glad to see any new conspiracy supporters.

The scrypt usage is not innovation (that's why Litecoin offers no innovation, unlike TBX).

Actually we are not pretending to develop something innovative. We are using bitcoin 0.7 with the transparent leveldb layer implementation as the codebase for our project, and trying to

1) promote the proof-of-stake/proof-of-work hybrid design;
2) implement the rewarding system which would be able to maintain the long-term proof-of-stake system stability through the self-regulation;
3) bypass some PPCoin flaws in our proof-of-stake implementation, in order to make it truly decentralized hybrid design.

And I presume that we are succeeded in this. We are also using checkpoints, for example, but that's really not necessary. Network is able to provide enough security without this subsystem.

What do you mean? The repeated small orders? They've always been there. It's probably somebody playing with a trading bot.

I'd like to see proof of that if you have it.  I don't believe that Novacoin has been to $20USD before.  Am I missing something?  How would you have seen those open orders to say such a thing?

If there was no pre-mine then BTC-e isn't currently sitting on $2.5mil USD in novacoin for which they created the value... amirite?

Or BTC-e is lying about Novacoin developers bribing them to offer NVC on the exchange.

Novacoin hasn't been to $20 before, this is correct. I didn't mean that those orders were in the book before today. What I meant is that somebody uses a trading bot to create those orders on the fly (they would be very tedious to enter manually). He's been doing it for a long time and I don't think anybody pays much attention to it, I certainly don't. It's the big orders that move the market.

I'm currently only invested in btc/ltc but was looking at some of the other altcoins to see if any looked attractive. I noticed NVC has been trading around $5 or so for a long time, and then yesterday it randomly shot up to $20+. Just curious what's going on with this coin as it seems really unstable if this is just due to technical trading, or if there was a real event that caused the value to jump?

I cannot answer what's the benefit of this trading strategy, but I've seen it quite frequently, often on cryptsy and mcxnow. Lots of These mini orders, and in many cases also twin mini orders (two orders right next to each other with the same tiny amount. Someone mentioned this is a trading bot called "jew bot" but I couldn't find anything on that.
My assumption is that These mini orders placed between larger orders are possibly supposed to "hide" an upcoming wall for the "Manual" Trader. But that's just a theory.
So sorry that I cannot provide a definitive answer other than that I frequently see this type of orders, it's not specific to NVC.

Kind regards
Mike

I just recommend any new comers to Novacoin, or to alt-coin trading in general, to do at least do 1 hour research into NVC before saying the old tired stuff.

Do you know what my first post about  Novacoin was, 8 months ago?  It was something along the lines of "Is NVC just the newest scam lol, what a joke" -- or something to that effect, check my post record if you don't believe me, maybe it was my 30th post (complete guess).

But you know what? I jumped the gun like many others and accepted the prevailing bad press about Novacoin. This is in part because of all the scam/dumb coins that do exist, which makes people defensive, understandably. Novacoin is not one of those.  I read up on it, Balt himself patiently addressed my own ridicule of the coin back then, and now 8 months later I can say come around 100%. I was wrong in my initial poor judgement NVC, and this changed after learning more about it.  

Just asking people politely to please read the facts (and not so much the press) and make your own judgement if you are new to NVC.  

Also consider the possibility that at least some of the people telling you it is such a bad coin could also just be trying to keep the price down for themselves.

edit: here's the link to my own post. Just want to show how much I came around from my initial impression to my sincere liking of the design of this coin:

The novacoin-qt client shows a 0 coin balance. When I repair the wallet the coins show up, all 4.09 of them. But as soon as I try to send the coins I get an error message saying: "Error: The transaction was rejected. This might happen if some of the coins in your wallet were already spent, such as if you used a copy of a wallet.dat and coins were spent in the copy but not marked as spent here." I have tried importing the private key to a different wallet with no success, it brings up the same error message. Any help that could be offered would be appreciated.

Edit: After 3 weeks of trying to process this transaction, 5 minutes after I posted this it cleared. Thanks anyway.

Today was the first time I've seen Novacoin mentioned in a major newspaper:

Quote
Novacoin

Yet another peer-to-peer digital cryptocurrency, Novacoin differs from most of the other altcoins by integrating protection schemes within the core of the currency, which deters abuse by mining groups.

Novacoin also has a technical cap of 2bn coins, a much larger number than most of the other digital currencies which top out in the millions, rather than billions of coins. The cap could also be increased if it was ever reached, giving novacoin a theoretical dynamic inflation.

http://www.theguardian.com/technology/2013/nov/28/bitcoin-alternatives-future-currency-investments

Is it really a good selling point to mention the 2bn cap but fail to mention that it may never be reached and that Novacoin is in fact one of the altcoins with the fewest coins in existence?

Novacoin has, in my opinion, the best design of all the coins. Sadly most people don't bother to do their own research and simply don't know how good it is. I think we should do some serious brainstorming and improve our marketing materials.

Here are the major selling points that come to my mind:

  • Great design: Combines the best qualities of Bitcoin, Litecoin and Peercoin with its own improvements
  • Very secure: Hybrid PoW/PoS design, attacker would need more than 50% of each to do double spending
  • Fairness: Most coins are mined by PoS and go to those who own NVC, not to those who have cheap electricity
  • Profitable: Considerable interest can be earned from PoS mining

Coins limit theoretically could be reached only in the very distant future, but another part of statement is correct enough. There are 3 basic factors which makes contribution into the resulting inflation rate:

  • PoW block reward (depends on the PoW difficulty);
  • CoinDays monetizing process (depends on the PoS difficulty && active inputs sum value);
  • Coins destruction through the network fees (depends on the market activity).

So, we theoretically have a dynamic inflation rate which depends on the audience size and the market capitalization.

P.S. Some rules may vary in the protocol updates (e.g. txfee per 1kb, see BTC or LTC for the real-life examples), but it has only a little effect on the final result.

As you know, SeaCraft game is on a straight path to Steam early access, where publishing is scheduled for January 30th.
 
And soon, December 18th, a big game update will come out. After this, the game testing will go in continuous mode, so Founders and Early Buyers will be most directly involved.
 
For those, who wants to buy Game Packs, Steam earlier game access or plans to buy a game after release, we have interesting news.
 
HG developers team always supports new technologies. That’s why we decided to accept cryptocurrencies – a gaining popularity way to make a payment. Bitcoin is the first and the most famous of them. But we are going to accept several cryptocurrencies. Below you can find a list. Since now, you are able to make a payment  with this cryptocurrencies:
 
  
Bitcoin, Litecoin, Terracoin, Novacoin
 
Commissions are low, and current price is determine by exchange rate of https://btc-e.com/
List can be extended, but reduction is not planned.
In February 2014 making payment may become automatic.
To buy a Pack with cryptocurrency now, please contact Titanium Beard with PM.
This would be our small contribution to modern technologies and progress.

Features planned for 0.4.4.6+

  • Deterministic wallets, i.e. keychains generation from seed (user supplied or automatically generated, see Electrum for example);
  • Separated databases for keys and transactions, instead of wallet.dat;
  • Add support for free transactions and decrease the price for 1kb (i.e. bitcoin-like fees scheme);
  • Remove lower output value limit for user and coinstake transaction types;
  • Add maxtxfee configuration option and RPC call;
  • Include PoW block txfees into the PoW block reward (like bitcoin does, to make transactions handling more profitable in comparison with empty PoW block generation).

Legenda:
Supported by users, investors and developers;
Questionable at the moment.

I think that PoS reward shouldn't include any fees, to maintain a deflationary component of emission process. Average rate of PoS blocks is 2/3 of total blocks rate, so ~2/3 of transaction fees will be destroyed by stake holders. However, a compromise is possible. For example, it's possible to include only a half of the fees, but for the both block types. But it technically complicates the system, so there is a lot of things to think about. That's why this idea was marked with the red color.

Average rate of PoS blocks is 2/3 of total blocks rate, so ~2/3 of transaction fees will be destroyed by stake holders.

I don't see why this would be a problem? I'm sure that many PoW miners are also PoS miners. One feature of PoS mining is that your inputs get approximately halved every time a block is found. Here's a hypothetical example:

You send 100NVC to your wallet. After 33 days you find a block and get 10NVC reward. Your 100NVC input gets split into two 55NVC inputs. 35 days later it splits into four 30NVC inputs and so on. After a year or so your inputs will be pretty small and it will take longer and longer to find a block. At the same time the difficulty is going up because of all these extra blocks. At this point one could start over and send the coins to a new address but that would most likely destroy a lot of coindays that would earn interest otherwise.

If you include transaction fees in PoS block rewards then this will offset some of the disadvantages that I have described, at least over the long term (transaction fees are minimal at the moment).

That's correct, for p2pool miners especially. :)

One feature of PoS mining is that your inputs get approximately halved every time a block is found.
Split is performed only if input has age lower than 90 days. Otherwise it's possible to get something like this:

Anyway, I admit that there is a sense in your proposal. Because even without fees destruction the system is able to maintain a deflation due to lost wallets and accidentally destroyed coins, for example. ::)

That's quite interesting news. I have been able to reduce proof size by 30-40% only. Will see... Although the 20-30kb proof size is not a serious problem, there are a lot of transactions with even higher size (something like 100kb) due to many inputs usage. This could be handled by regular fees.

Deterministic wallets, i.e. keychains generation from seed (user supplied or automatically generated, see Electrum for example);

First test of hierarchical keys generation algorithm. :)

1. Creation of public & private key trees using seed (unlocked wallet emulation):

2. Creation of public keys tree using master public key and master chain code (locked wallet emulation):

You need to register a new account, create worker and then point your miner to URL which provided by pool. You can use cgminer, bfgminer or reaper with stratum-mining-proxy.

Settings will depend on your hardware. Here is an example for Radeon HD 7950:

Code:
cgminer --scrypt -I 18 -g 1 -w 256 --thread-concurrency 21712 --gpu-engine 1070 --gpu-memclock 1400 --gpu-vddc 1.089 --temp-target 80 --auto-fan -o stratum+tcp://coinpool.ru:3333 -u username -p password

P.S. I heard that the new versions of cgminer has no GPU mining support, so you have to use bfgminer or previous versions of cgminer.

Hi. First of all, congratulations with starting up. :)

But I should warn you that NVC uses own block format, that's why unmodified mining software can't work properly. Make sure that you are using an appropriate snapshot of StratumServer. Otherwise you'll lose mined blocks silently.

You need this to mine NovaCoin:

Post by: glendall on December 26, 2013, 08:25:02 PM
Hey if any super-knowledgeable person could help me out with this PoS question that'd be great.

So I have 2 nova wallets on 2 separate PCs. Both had balances transferred to them on the same day. About 30+ days later, one of the wallets generates a PoS block while the other does not.

1) Is this pretty normal? Is it correct to think that finding a PoS block is unpredictable, the chance increases as time increases ? Or in this scenario should they find blocks at the same time / same day?

The only difference between the two wallets is that the wallet that has not found a PoS block has been receiving a few coins from my mining. But I used a seperate address in the wallet for that, so that should not affect the coin-age of the balance that was already there, is my understanding. Is this correct?

2) After my first PoS block matures, should I transfer the new balance to another address in my wallet to restart the PoS process, or is it just as effective if I just leave it as is. Will a new PoS block eventually be found if I just leave it alone, once the new 'stake coins' return to my balance, without having to move the coins to a new address?

Thanks if anyone has the answers to these.

1) It's a mining, just like with PoW. Block generation is a stochastic process, you can calculate average generation time but you can't predict the exact time.

There is no influence from incoming transactions, even if those transactions are sent to the same address. And you are right, block generation chances are growing in time.

2) No, you don't have to do anything. Age is calculated since input creation time and it doesn't matter how those inputs are created.

Title: Feature Request
Post by: KleinMatthias on December 27, 2013, 09:59:18 PM
Hi,

Since not all users of this coin are as active as you are, may I ask for a feature in a future wallet version?

Please implement one of the following features:
1) an autoupdate feature which automatically keeps the QT updated without the user doing anything (or with the user just clicking an "update" button which only appears when new updates are available - but where the entire update process is done automatically)
2) a notification feature where the user can enter his eMail address into the wallet and the wallet sends him an eMail when a new version is available? That requires - of course - that the wallet has a way to check for updates. But since Microsoft/Apple/Adobe/andalltheothers can do it, so can you :-)
3) (for those who don't even run their QT all the time) a notification feature where the user can enter his eMail address into the wallet and the wallet sends that eMail address plus its own version information to a central server of yours which then sends out an eMail when a new software version is available. And which sends a warning eMail when a mantatory update has to be performed.

Naturally, as of today, the Cryptocurrency-community has been very active but with the price explosion of the Bitcoin last month, more and more "normal users" will enter the market.
They will not keep their wallet running all the time.
They will not check the forum all the time.
But they might spend hard cash on buying this coin at an exchange and then send it over to their wallet. As a community, we even need that kind of passive user - and we need their money buying this coin.
And when they find ways to spend or donate the coin, they will. And for that purpose they will open their wallets - but not in between.

Having said this, I personally prefer feature (3) because it has a few advantage over the other 2:

  • It keeps even those "passive" users in the loop that do not run their wallet regularily.
  • That way, if a really important change has to be made (e.g. a new blockchain), even those users won't lose their money because they get a notification. Think of the bad publicity when "normal users" start losing their money because they simply ignored their wallets for months only to find them not working anymore because weeks before, a new blockchain or equally invasive measure was introduced without them knowing.
  • That feature can be extended for marketing purposes: add a checkmark "the makers of this coin are allowed to send me exciting news about this coin yaddayaddaya" - and voila you get yourself a free marketing database with tons of eMail addresses that you can use to keep engaging your users. Notify them of new shops where they can pay with this currency. Notify them of faucets. Notify them of exchanges that trade this coin. Notify them of the rise in value of that coin. And so on. Just keep engaging even the passive users - because to make a currency successful, you need every hand and every dollar you can get.

You guys and all the other professionals or those that have privacy concerns won't use that feature - and should never be required to do so. But the regular passive user will get that fuzzy feeling that he will be informed of important stuff without him spending much time checking bitcointalk or their wallets. And that will give him extra confidence when it comes to him spending the coin or buying the coin with his FIAT.

Just a few additional remarks:

  • Naturally, the best possible combination would be (3) with (1) where the users gets a "move your ass and update your wallet or else..." eMail (friendly version, of course) - and then he opens the wallet and clicks on the "update" button and that's it for him.
  • May be the required serverside portion (the thing that collects all version information and the eMail addresses and which also allows for sending out mass eMails to all users in that database) could be written in a generic way so that other virtual currencies can implement that feature, too?
  • May be, future wallets should have a default setting that causes them to run in the background as a service whenever the computer starts. That way, even many passive users will contribute to the P2P network without them even knowing. But that was just a sideline remark and describes a completely different feature request. But then again, while you are at it... :-)

Don't know. What do you guys think about that feature request?
Does anyone second that request?
Does anyone have a better idea how to solve the above mentioned challenges that this new species of regular, passive users will introduce in the weeks and months to come?

Thanks
Matt

Actually there is no reason to worry, incompatible client will be rejected by the rest of the network, and then user will see the update notification.

There are no crypto currencies with automatic software update, and that's not a matter of privacy. It's a matter of security, an act of centralized distribution of malware is able to crash the entire P2P network.

http://techblog.avira.com/2013/06/27/opera-com-hacked-distributed-malware-signed-with-their-certificate-to-probably-thousand-of-users/en/

There's no way to guarantee that automatic update server won't be hacked or something like that.

https://github.com/CryptoManiac/novacoin/commit/def6e8bd0d036ba0c41d1d38654bb2b454b5e296

For somebody who like to perform experiments. :)

Quote
Implements a basic support for deterministic keys generation.

Please note that this feature is very experimental for now. This code is incompatible with old wallet.dat format, don't try to run it in production or without backups.

This commit provides some new RPC commands:

* createroot [seed] - create a new root node from supplied or random seed
* dumpnode <novacoinaddress> - dump node into serialized data
* importnode <seriaizednode> [label] - create a new node using supplied serialized data
* getchildof <novacoinaddress> [fPrivate=false] [label] - get new child for supplied node
* listroot - list root nodes available
* listchild <novacoinaddress> - list a child nodes for a supplied address
* listorphan - list orphaned nodes, i.e. addresses without parent nodes
* listrandom - list randomly generated addresses
* rescan - similar to -rescan key

Removed RPC commands:

* keypoolrefill [n] - there is no keypool anymore, so we don't need this
* getnewpubkey [label]
* validatepubkey

Updated RPC commands:

* getnewaddress [label] - now creates a new child address for a public root instead of getting it from key pool
* getaccountaddress <account> - similar to getnewaddress
* dumpwallet <filename> - now able to dump HD nodes
* importwallet <filename> - now able to import HD nodes from file
No builds available yet, win32 and linux builds will be available later. Please read a commit description before trying to use it.

TODO:

1. Public key trees generation without unlocking of wallet;
2. Split wallet.dat into local transactions database and keystore;
3. Automatic recovery of key trees in case of database failure;
4. <...>

Win32 / Win64 build: http://sourceforge.net/projects/novacoin/files/experimental/novacoin-nosetup-0.4.4.7-test-windows.zip/download

Some examples of usage.

http://pastebin.com/vCjj8Ya6

  • Key tree navigation (get a list of root nodes, move down from root to grand-grandchild);
  • Node addition using a public and private derivation functions.

http://pastebin.com/zdBhmyHm

  • Get a list of root nodes, create a new one using radom seed and validate it;
  • Create 3 child nodes with private derivation function;
  • Create  3 grandchild nodes using a public derivation.

http://pastebin.com/REf2pgTQ

Similar but using ultrasecure passphrase for root generation  :D

http://pastebin.com/Sy4qMwk0

Create new addresses and then get a child list for parent address.

Hi Balthazar,

I like your support and the new features being added and would like to support that, but I see you don't have a Novacoin address in your footer (shame on you!! :-) ), so I'll wait and see whether you add one..

Kind regards
Mike

P.S.: Nice giving us the deterministic wallet feature - will there be included a feature into the client to print it out in a nice, good-readable way with basic instructions on what it is, plus a GUIey way to add it to the wallet? With more non-techy people entering into crypto, I think we need more user-friendliness than just a Text console somewhere in the menus.

This feature is very experimental for the moment and presented in a separate branch only. This client has no key pool and only way to generate new addresses is CKD function usage. "Create new address" button uses the CKD function too.

BTW, if everything will be fine with my network today, then I'll publish 0.4.4.6 update soon... This update should include optimized block index code.  :)

Testing results on celeron 880 with fully syncronized blockchain:

0.4.4.5 - block index load takes 126 seconds;
0.4.4.6 - block index load takes 7.26 seconds only.

Cache scrypt hashes on disk
instead of recalculating every time. This policy is able to give us 10-20x startng speed up. User can disable caching with -fastindex=0 option.

Note that this commit makes blockindex code incompatible with old blockchain database files. You need to remove old blockchain files and syncronize with the network again.

Another changes:

1. Stake pooled keys are removed.

Happy new year, guys and ladies! :)

P.S. Builds will be published tomorrow.

Serious issue was found with 0.4.4.6 installation packages, those installers could function improperly on some systems. So, installation packages were replaced with corrected ones.

---

64-bit installer replaced, sha1 sum of the correct file is 8a8eac4c2abd70e94520014dfe67faa63945e2c3
32-bit installer replaced, sha1 sum of the correct file is ae600c0df9f5367787ff1ba9a401e3858005ee70

You can verify sha1sum of your file using QuickHash utility:

https://sourceforge.net/projects/quickhash/

If you have downloaded a new installation package recently then it's highly recommended to check your client version (see Help -> Debug window). If it's 0.4.4.6 then you can ignore this message, otherwise you need to download a corrected package and install it as usual.

P.S. Don't forget to remove the old blockchain database files while upgrading to 0.4.4.6 version.

---

Advice #1: Always back up your wallet.dat to make sure that your money are safe.
Advice #2: Always use encrypted containers for your backups. For any sensitive data, not only wallet.dat.

Attention to all users of novacoin.

Chain fork happened due to fee calculation issue with block #65873. The following short FAQ should be helpful in order to resolve this problem.

-------

Q: I've got an alert message from my Novacoin client. Is this right thread?

A: Yes, that's right thread.

Q: What's happened?

A: Some clients has this block (http://nvc.cryptocoinexplorer.com/block/aab5ad74039e711b3afb52127c0ea6eaac5bc756c41d76ca0460ea29d0ec85f2) rejected while the most part of nodes accepted that without any problem. That's caused a chain fork which couldn't be resolved automatically.

Q: What should I do?

A: You need to install 0.4.4.5 or 0.4.4.6 update, these versions are not affected by this issue.

Q: Why I'm getting runaway exception while trying to start 0.4.4.6 client?

A: That's normal, it's happened because 0.4.4.6 update makes blockindex code incompatible with previous versions. You need to remove old blockchain files and resyncronize with a rest of the network.

Q: How to remove the old blockchain database files?

A: You need to remove everything except wallet.dat from your client data directory. Data directory is located at

Windows Vista/7/8/2008 Server: C:\Users\<UserName>\AppData\Roaming\NovaCoin
Windows 2000/XP: C:\Documents and Settings\<UserName>\Application Data\NovaCoin
Linux/*BSD: ~/.novacoin

Q: Where I can find update packages or source code?

A: Binary updates could be downloaded here (https://sourceforge.net/projects/novacoin/files/). Source code is available at github (https://github.com/novacoin-project/novacoin/).

Q: Is there any affected versions list?

A: All clients with protocolversion value lower than 60010 are affected by this issue. You can check your protocolversion value using getinfo command. If you are using a binary builds prior 0.4.4.5 then it's necessary to apply update.

Q: How to shut up this alert message?

A: You can apply 0.4.4.6 update and warning will disappear. You can also ignore it or wait until alert will be cancelled.

Q: Is there any list of unaffected resources?

A: It's confirmed that novacoin.ru/novacoin.su/explorer.novaco.in, nvc.khore.org, coinpool.ru, virpool.com and btc-e.com are on the right chain.

Hi Slipknot79, that's correct.  ::)

It's a notification, which was sent as a warning. Please verify your syncronization status and install update if it's necessary. Or just install an update without checking. :)

Heymdale

How you got this 15 coins in the wrong chain?  ::) BTC-e follows the right chain originally. There is no PoS or PoW difficulty (http://charts.novaco.in/#difficulty) drop happened, so the most pools and holders did the same... Maybe somebody sent you this coins and then spent it again in the right chain? Like somebody did (https://bitcointalk.org/index.php?topic=152348.0) against OKPay at the spring... :(

Of course you are free to choose but the fork is happened due to bug in the old clients, not because of any feature. By following fork you are following a buggy version. ::)

Wrong chain contains 20 blocks since #65873, while the right chain has 370 blocks length and 520 blocks maturity window will be reached tomorrow. I really can't see the reason why this 370 valid blocks should be wasted in order to restore 20 invalid blocks from the wrong chain.

P.S. PM sent.


OK I understood, it was funny, thanks for joke. :D

=============

Proof-of-stake difficulty 0.1 is finally reached!

Changes planned for 0.4.4.8:

  • Separate databases for private keys and transactions, instead of wallet.dat;
  • Moving the public data to separate folder (e.g. move blockchain database to AppData\Local\Novacoin on Windows);
  • Switching to UTXO storage (similar to used in the Bitcoin, but with extended metadata) instead of the current full transaction logs approach;
  • Switching to deterministic keys, and possibly withdrawal of the keypool approach;
  • Withdrawal of the Berkeley DB support (LevelDB is used by default for a long time).

This changes will be implemented in the 0.4.4.7 testing branch, the 0.4.4.7 binaries will be rebuilt and published sometimes, just for testing purposes.

Parts of this functionality are already available for testing.


Title: Re: [ANN] official NovaCoin thread - the original PoS+scrypt coin. --POOL LIST--
Post by: yonillasky on January 08, 2014, 12:01:01 AM
I have a question/proposal regarding the PoS minting process.

After some cursory analysis, I have realized that the rate in which PoS blocks are generated implies a certain upper bound on how many different chunks of coin there can be, before the relatively smaller ones would start taking more than 90 days on average to hit the PoS "jackpot".

This is a bit of a problem as it means getting into NVC and enjoying a roughly equal footing requires a certain coin amount, which limits the rate of adoption for this coin. I haven't done exact calculations, but it seems that it may start being a significant problem for wallets with around 10**-5 of total NVC (so ~5 NVC right now). It might become a non trivial amount if NVC were to appreciate in monetary value. It limits us to a few thousand users that could use PoS to full effectiveness, right?

Am I missing something here?

If not, fixes that come to mind are,

1) faster blocks (a pretty huge change that may be out of the question for an established coin)
2) somehow have multiple PoS minting transactions per block, though keeping the interest generated the same as it is now.

I am not aware of the low-level/implementation details of PoS minting so I don't know if (2) is a reasonable option either

Just an idea

There are several factors that weren't taken into account.

1. Old inputs has an ability to recombinate into the larger one. So, inputs count would regulate itself depending on the difficulty and sum.

2. Proof-of-Stake system is not an enrichment tool, it's just a network protection mechanism. It doesn't matter how much time would take the specific block generation. All that matters is how many blocks created by a whole network, with an established difficulty factor.

3. We have no thin clients implemented yet, but I guess that the most part of users would prefer these because they don't need a full database for payments processing. So, a few thousands of mining nodes that's quite enough to provide an acceptable level of decentralization.

4. Nobody forces user to participate in mining, but if he wish to participate then it's required to accept and follow the rules and restrictions. Just like a PoW miner accepts the PoW difficulty. But unlike PoW mining, everybody has a chances here, because Proof-of-Stake mining consumes almost zero resources amount.

Regarding item (2), in general I agree with that, but so long as it pays significant interest, it cannot be dismissed as merely an infrastructure component. Once the stake interest drop to a few %/yr it won't be a problem, but right now it does have some drawbacks,

1) constantly dilutes small holders, or those who would keep some or all of their balance at an exchange, at least until someone opens an exchange that pays some or all stake rewards to its clients - there's an idea, but I doubt anyone will bother, sadly
2) it works as a disincentive to actually use the coin (you know, transact with it) as that resets coin age.

That's correct, but we are still at the initial emission stage. :) It's only a matter of time when a proof-of-stake reward will be dropped enough.

This would be mean that formation of the initial stakeholders community was done successfully. Then we can dedicate some time to think about adjusting a minimum level of the proof-of-work difficulty, if it would be required to make an adoption easier. Such decision could be made with block versions voting, like we already did (https://github.com/CryptoManiac/novacoin/commit/65abc2081496fed54e01b6f3b43db2df6d52a665#commitcomment-2884046) before. Time will tell.

I didn't know this. Under what circumstances will small inputs recombine into a larger one? Can you show us a transaction where this has already happened?

It happens when inputs has age greater than 90 days.

But there are some limitations:

  • Only inputs with an equal destination are combined;
  • Maximum sum of combined input is defined as a linear function of the proof-of-work block reward (PoW/3).

Hi guys. :)

This message is just a notification which was used to send users read the FAQ in this thread.

Check your client version, if you are running 0.4.4.5 or higher then it's safe to ignore this message.

Q: Why I'm getting runaway exception while trying to start 0.4.4.6 client?

A: That's normal, it's happened because 0.4.4.6 update makes blockindex code incompatible with previous versions. You need to remove old blockchain files and resyncronize with a rest of the network.

Q: How to remove the old blockchain database files?

A: You need to remove everything except wallet.dat from your client data directory. Data directory is located at

Windows Vista/7/8/2008 Server: C:\Users\<UserName>\AppData\Roaming\NovaCoin
Windows 2000/XP: C:\Documents and Settings\<UserName>\Application Data\NovaCoin
Linux/*BSD: ~/.novacoin

You can continue using 0.4.4.5 like btc-e does, but it's better to apply 0.4.4.6 because it works much faster and ignores the current notification.

P.S. "Much faster" is up to 20x speed up on a slow CPUs like Intel Atom or ARMv6.

Just a little piece of info...

As far we know, some payment processors and users accepts 0/unconfirmed transactions. But this solution is not secure, because it's possible to create two transactions with the same inputs, but different outputs.

http://eprint.iacr.org/2012/248.pdf

Attacker is able to send a first transaction directly to victim, and then broadcast a second transaction over the network. This couldn't be prevented using the proof-of-work design, but it's possible to fight with such manipulations through using an extension for our proof-of-stake system, and we even don't need a chain fork to implement this.

Block candidates submission concept

This would allow user to check that his unconfirmed transaction is accepted into the specific stakeholder's memory pool.

It doesn't provide guarantee of fast confirmation, but it makes a double spending of 0/unconfirmed transactions much harder. It will be required to use some stake in order to perform such type of double spend attack.

How this could work?

1. We have a blockchain, so we can get a full list of stakeholders with suitable inputs weight (i.e. users who are able to generate proof-of-stake blocks and allowed to submit the block candidates);
2. We can check a signature of received block candidate;
3. As a result, we have a proof that specific stakeholder has a declared list of transactions in the own memory pool. Or seen those transactions, at least.

How is this supposed to work?

Stakeholder will be allowed to send proof-of-stake candidates over the network. Candidate is required to satisfy a difficulty, which would be set separately from the main chain. And then there are few different approaches could be used to handle this.

  • Block candidates map;
  • Temporary pseuso-chain for block candidates;

Maybe we'll think about implementing this in the future version... ::)

Both of these will require resource allocation at each (?) wallet. Do you have estimation of how much that could be?
It might be reasonable to only let some of the nodes do this kind of work. Presumably, whoever handles payments will run more or less a dedicated node with enough resources.

Post by: Balthazar on January 09, 2014, 09:26:31 PM
We need candidates for the current prevhash only... It's not necessary to store old candidates, we are free to drop all of them immediately if prevhash was changed (i.e. new block was found). It would require something like 10 megabytes of additional RAM, I guess.

You are right, not everybody need such functionality. But for some purposes (e.g. payments for fastfood) it's almost equal to immediate confirmations, so I presume this would be useful. ::)

I am curious of opinions from the community about mining Novacoin VS. pointing my miners at the currently most profitable coin and then buying novacoins with the earnings.  Mining on Novacoin will be better for the network, but buying it on BTC-e with earnings from one of these multi-pools will get more NVC in the end, and in theory will raise it's mining profitability attracting more hash power.  Which do you think would be most beneficial to the coin?

Another thing that I would like to comment on and is somewhat related is the ramifications that scrypt FPGAs will have on the NVC block reward  ;D

When the more powerful ASICs really started hitting the pools, PPC hash rate would spike every time BTC difficulty adjusted which in turn pushed the block reward down.  It seems many miners took an interest in PPC after these profitability spikes happened.  This appears to have benefitted PPC greatly regarding the market price.  Many thought PPC would be super plentiful, because people didn't imagine how much the block reward would change.

I think it is safe to say that there are currently scrypt FPGAs in the wild or at least a dump truck full of new GPUs mining scrypt from profits of the past months.  As these FPGAs start to ship out, the NVC difficulty will more than likely increase which will make the block reward smaller.  Anyone else think we will see < 1 NVC PoW block reward in 2014?  Talk about a rare coin!

Novacoin, it's like gold bullion bars to Bitcoin's 1oz round

Switch to unspent coins approach

This commit replaces old transactions index with unspent coins database
which contains a basic metadata like heights, amounts, coinstake/coinbase
flags and timestamps.

We still need access to blockchain for proof-of-stake blocks validation.
Currently CheckProofOfStake() uses the coin database to find the block height,
and then scans that block to find the dependency of coinstake kernel.


Batch block connection during initial block download

This reduces the load on the database engine, as subsequent blocks often
update an earlier block's transaction already.


As a result we've got a significantly smaller (~30% drop of size) and faster database.

Windows binaries will be published soon.

I am completely new to NVC... downloaded the latest win client v0.4.4.6 and getting the following error on launch:

Any ideas? Thanks!

Q: Why I'm getting runaway exception while trying to start 0.4.4.6 client?

A: That's normal, it's happened because 0.4.4.6 update makes blockindex code incompatible with previous versions. You need to remove old blockchain files and resyncronize with a rest of the network.

Q: How to remove the old blockchain database files?

A: You need to remove everything except wallet.dat from your client data directory. Data directory is located at

Windows Vista/7/8/2008 Server: C:\Users\<UserName>\AppData\Roaming\NovaCoin
Windows 2000/XP: C:\Documents and Settings\<UserName>\Application Data\NovaCoin

It doesn't matter if you haven't specified data directory path manually. It tries to load transactions database from %UserProfile%\AppData\Roaming\NovaCoin folder. ::)

Testing builds were updated.

Changes list:

  • Refactoring of Proof-of-Stake checkings code;
  • Remove some redundant messages from debug.log output;
  • Make stake related DoS checkings harder;
  • Database code is updated, direct CCoins links approach is implemented to decrease count of worthless flush and copy events;
  • Initial block download optimization, transaction hashes are cached now to make blocks validation faster;
  • Multiple CChainDB instantiations were replaced with a single CBlockTreeDB instance;
  • CCoinsDB and CBlockTreeDB are updated to use LevelDB storage;
  • gettxout and gettxoutsetinfo RPC calls added;
  • getblock and getblockbynumber RPC calls are now providing generator public key for proof-of-stake blocks.

Additional notes:

  • This builds should be considered as pre-release, i.e. it could be used for a new release if there will be no new critical issues;
  • If you see zero balance after updating then execute repairwallet command using RPC console and restart your client.

Rebuilt and uploaded.

Changes list is pretty small:

  • Changes done by repairwallet RPC command now applied on the fly, so it's not required to restart client after integrity checkings;
  • Block and transaction timestamps were added to gettxout RPC command output.

Deterministic wallets status.

WD wallets support is already implemented in the novacoin-hdkeys testing branch and works pretty well. So it's planned for integration into upcoming 0.4.4.8 release, but with one little change

According to testing results we shouldn't abandon the keypool approach. Instead of this we have to implement a separate and deterministic key pools for required purposes (receive, mining and change addresses).

As a result we've got this:

  • Winsock related compiler warnings are fixed;
  • You don't need repairwallet after upgrading anymore, wallet consistency being restored automatically during initial download process.

I guess that it's a last testing build and v0.4.4.7 will be released at monday.

Is the p2pool software incompatible with the current version of novacoin or something?

Running the p2pool gives me this:

Nope, there are no incompatible changes. I see that it happens sometimes with p2pool for different cryptocurrencies. Is the 7777 port available for connection?

By the way, new p2pool is coming soon.

Thanks for the quick reply!

I found the issue - it is that p2pool doesn't like the max connections setting...
I have it connecting to a local novacoin-qt now with the following novacoin.conf

Code:
rpcuser=bitcoinrpc
rpcpassword=IUSESOMETHINGELSE
daemon=1
server=1
[b]# maxconnections=16[/b]   <-- hangs p2pool, don't use

Hm... I have no idea why you've added this setting. It's P2P connections limit. :)

Quote
rpcuser=bitcoinrpc
rpcpassword=IUSESOMETHINGELSE

I recommend you to set a random RPC username/password and make sure that your 8344 port isn't available for incoming connections from the internet. We have enough skiddies who scans the novacoin network and trying to find p2pool users with opened RPC port.

You can see the getblocks looping, i.e. going up to 68859, then starting again at 65859. Since unfortunately it doesn't log IP I cannot see if it's always the same node requesting this.
When stopping & restarting the node , it stays normal for several days until I start seeing this again(happened about 5 times so far). Otherwise, the node seems to remain functional, i.e. forwarding blocks etc.
Anyone else seen this behaviour?

Hey everyone,

Just wanted to share some love regarding Novacoin.  I've been creeping these forums for months and there are very few that deserve a "pat on the back".  Many of you on here have given some great opinions regarding the coin and it's future and have helped me through some doubts.  In hindsight, I'm glad I've supported this coin and it's devs.

Keep up the great work guys.

I seen that many times on my cubie and I see this now on my VDS.

I don't think that it's the same node, I think this requests are coming from buggy nodes (< 0.4.4.5). The buggy client is able to see that network is on the longer chain currently, but unable to accept this blocks. That's why it tries to sync again and again with a randomly chosen node, bans it and then tries to sync from another one. This can cause some traffic or CPU overhead on normal node, but overall, it's harmless.

We'll add a special condition for incoming connections initiated from versions prior to 0.4.4.5. ::)

You can use a small patch to resolve this by yourself:

P2Pool is updated to support connections with v0.4.4.7 nodes.

sources (https://github.com/CryptoManiac/p2pool) | Win32 py2exe (http://sourceforge.net/projects/novacoin/files/p2pool_win32_p2pool-11.4.4.zip/download)

Older versions won't be able to establish P2P connection with v0.4.4.7 client due to obsolete protocol version. So, if you are switching NVC client to 0.4.4.7 then you need p2pool update as well.

It seems that you have mined some blocks for the wrong (https://bitcointalk.org/index.php?topic=143221.msg4310529#msg4310529) chain. That's not a problem for stake blocks, because those inputs were recovered during synchronization process. With this recovered inputs you are able to find some valid blocks again. :)

Hello group!

I was hoping you could help me make contact with the creator of NOVAcoin?

We are hosting The Crypto Currency Convention in NYC on April 9th. We would like them to speak and promote NOVAcoin.

Our mission is to bring awareness and acceptance to all Crypto Currency and not just bitcoin.

Education and exposure is the only way we all win.

We are expert marketers and expect 1500-2000 attendees.

If you could please forward a message or somehow make an introduction, it would be greatly appreciated and productive.

Thanks!

That´s why you have to keep your NVC client updated. PoS mining is cheap and easy, but it does require a minimum of supervision and maintenance. If you had kept an eye on your miner then you would have noticed earlier that something is wrong.

Serious issue with stake modifier calculation was found right now at block #72810. If you are using 64 bit windows version of 0.4.4.7 client, please shut it down and use 0.4.4.7 32 bit or 0.4.4.6 / 0.4.4.5 instead, until this issue will be investigated.

We are sorry for inconvenience. :(

P.S. If you've decided to switch from 64 bit to 32 bit build then you need to download a fresh copy blockchain. That's necessary because old one could contain the wrong checksums created by buggy build.

Post by: glendall on February 04, 2014, 11:49:41 PM
Aw crap think that might have might have been a problem that I had with the 4.4.7 64 bits Windows. From both of my wallets on two separate boxes they had POS stakes generated for only 40% / 55% of the wallets balance, whereas before it has been POS block proportional to 100% of the balance. Was that the issue? I'm still a bit new to how POS blocks and how they are calculated.

Actually no I forgot, one of my wallet boxes is running Debian linux 0.4.4.7 beta, not Win 64,  so I guess what happened wasn't a bug.

Anyways, will keep updating to newest release.

Post by: Balthazar on February 04, 2014, 11:53:07 PM
It's a floating issue. Sometimes it happens, sometimes doesn't. So it's possible to have windows 64 bit build working correctly. ::)

If you have no synchronization issues (i.e. your wallet is on a top of the best chain), then it's generally OK. But you can get modifier checksums for some blocks and compare it with values you've got from another client... Some values, for example:

# 72837  "modifierchecksum" : "8378242b",
# 72834  "modifierchecksum" : "0816d578",
# 72830  "modifierchecksum" : "cafd1f98",
# 72810  "modifierchecksum" : "aab46337",

If your values are different then there is a problem. Use getblockbynumber RPC command, it's quite helpful for such cases. :)

I think that we'll find a reason in the next few days.

Some users reported syncronization issue with linux builds too. So, it was decided to remove 0.4.4.7 version from repository and send alert notification over the network. Downgrade to 0.4.4.6 or 0.4.4.5 is required to keep your wallet stable, the main repository is downgraded too. If you are using 0.4.4.5/0.4.4.6 releases then it's safe to ignore this notification.


There were more than 10 testing builds with 482 downloads and nobody seen this issue before. We are sorry for inconvenience. :(

Ok switched to the 0.4.4.6. Deleted my Novacoin %appdata% directory (after backing up my wallet of course).  Started novacoin-qt to d/l block chain and still getting the message about there being a sync issue and to downgrade to 0.4.4.6.

I'm using the recommended version (I think)  v0.4.4.6-nvc-dirty-beta .

0.4.4.6 and 0.4.4.7 are using the same protocol version 60011, that's why 0.4.4.6 users see this message too. But it's safe to ignore for 0.4.4.6 users.

I think it syncronizing, but you can't see the progress bar if there are any alerts active. You can check a syncronization progress in the debug window (help -> debug window).

Yep, that's crazy  :o I wonder what would happen with proof-of-stake difficulty if this (http://explorer.novaco.in/address/4PcqmSFpXBabcZXW77MYK4ALN9kVG9yhG1) holder will open his wallet.

P.S. It's planned to remove JSON-RPC interface support in the next p2pool update. So, next p2pool release will be stratum-only. Postponed to a future release.

P2Pool was updated to 13.4-25. It's recommended to apply this update because it fixes an issue with block header timestamp. This issue could cause generation of invalid blocks.

By the way... From this day I'm starting to divide some coins between active p2pool miners once per 24 hours. :)

If somebody want to do the same, it's quite simple.

There are a few examples:

1) Distribute 1 coin proportionally between active miners:

Code:
novacoind sendmany "" "$(wget -O- http://IP_P2POOL_SERVER:8336/patron_sendmany/1)"

2) Distribute 1 coin per 24 hours automatically:

Code:
0 0 * * * novacoind sendmany "" "$(wget -O- http://IP_P2POOL_SERVER:8336/patron_sendmany/1)"

3) If you have no experience with linux or cron you can distribute some coins manually. Just open http://IP_P2POOL_SERVER:8336/patron_sendmany/N in your browser, copy the output and execute the following command using your RPC console:

Code:
sendmany "" 'OUTPUT'

Have fun :)

Well... It seems that current 0.4.4.7 testing branch runs pretty stable for now. This branch is available here for public testing:

https://github.com/novacoin-project/novacoin/tree/current

Basic list of changes:

1) Pruned transactions serialization support.

Pruned transaction records are now saved into coinsDB. These records are composed of 13-14 bytes of metadata (block height, coinbase/coinstake flags, block and transaction timestamp). This resolves all syncronization issues. Though currently there is no lifetime limit for such records, cleanup for old records will be implemented in the future versions of NVC client (this cleanup will be performed after reaching the 520-blocks maturity window, I guess).

2) Conflicted transactions handling.

Just wanted to say great work on this coin, I have been scooping these up as they slide for some unknown reason.

Also I recently updated my coin(fork for NVC) to be ready to QT5. I would be more then happy to issue the same PR for NVC if you would find it useful.

Thank you and good luck.

Yep, I seen it. :) Actually we are working on Qt5 too but it's not published due to recent issues with 0.4.4.7.

By the way, 0.4.4.7 branch seems pretty stable so builds are scheduled for publishing. :)

Also we'll update reference stratum server code to add vardiff support.

Protocol update: preconditions and prospects.

A new proposal for Proof-of-Work signing protocol is currently under development. It would provide stakeholders an ability to vote for Proof-of-Work blocks they've received. What is interesting, it's possible to implement without breaking a compatibility with nodes that doesn't support this protocol.

A main idea is quite simple:

1. Proof-of-Work miner submits a new block over the network;
2. New block is accepted as a "candidate" (score = 1);
3. Each node builds a deterministic list of stake generators from the past (64 items, for example);
4. Stake holder appends own signature to vchBlockSig field (currently it's not used) and then submits signed block over the network;
5. Once enough signatures collected (16 of 64, for example) new block is accepted into block chain as a "full value" block (score is equal with provided by the current proof-of-work score policy).

This process would be able to prevent malicious miner from creating a secretly pre-mined chain in order to perform 51%+ attack even if he has 99% of hashing power and significant stake volume. Because he can't collect enough signatures while keeping his chain secret.

Hello,

In this commit: https://github.com/novacoin-project/novacoin/commit/b9c711308fc96540c0a22c7aba0707d90460c0a1

It seems that line 394 in wallet.cpp, (CWallet::WalletUpdateSpent):

Code:
NotifyTransactionChanged(this, hash, CT_UPDATED);

Is not needed as it causes a warning:

Code:
02/22/14 08:29:22 Warning: updateWallet: Got CT_NEW, but transaction is already
in model

When returned back to CWallet::AddToWallet  and the next line try to notify transaction as new.

At least I think that is why. I commented out the new Notify and no such warning and still received notification in wallet of new block found.

That's quite interesting news. I have been able to reduce proof size by 30-40% only. Will see... Although the 20-30kb proof size is not a serious problem, there are a lot of transactions with even higher size (something like 100kb) due to many inputs usage. This could be handled by regular fees.

You are right about energy efficiency but there are a some problems:

  • AUX PoW is cost-free for a miner;
  • There are a few big mining pools which will be able to introduce a centralization into PoW mining.

These things are serious problem because one or two big LTC pools will take a major part of PoW emission for free. I presume that we shouldn't introduce a possibility of this scenario, especially if the pool operator decides to keep mined coins for himself instead of distribution. Because it allows somebody to get a significant part of stake for free, which contradicts to the network security model. ::)

Post by: Bitinvestor on February 26, 2014, 07:29:38 PM
AUX PoW is cost-free for a miner

Yes, and that means we could reduce the PoW reward from currently about 10NVC to maybe 1NVC or so. That would restrict the supply of new coins and help lift the price.

If significant extra income can be achieved from merge-mining NVC then miners will naturally choose the pools that will pay it to them.

I believe that if this is done right it could give Novacoin a much needed boost.

Post by: Balthazar on February 27, 2014, 03:21:00 PM
Maybe you are right but it couldn't be added without an appropriate discussion... I've already thought about a separate AUX PoW block type with own difficulty and reward ~6-7 months ago but this proposal was rejected... ::)

The main argument is that balanced (proof-of-stake + proof-of-work) system is self-sufficient while (proof-of-stake + auxiliar proof-of-work) doesn't provide a self-sufficiency because it depends on stability of auxiliar chain. So we have to keep a support for native proof-of-work along with auxiliar proof-of-work to keep self-sufficiency.

This solution sounds simple but it's impossible to implement a sustainable proof-of-stake + native & auxiliar proof-of-work system. It's impossible due to self-competition between native & auxiliar proof-of-work miners.

Why self-competition isn't a good thing? It's quite simple, just one example:

PoS -> PoS -> PoS -> PoW -> PoS -> PoS -> PoW -> PoS

vs.

Which chain should be preferred? It's obvious that auxiliar proof-of-work difficulty will be higher than native proof-of-work difficulty, so the last chain will be selected. But this solution is flawed because it makes native proof-of-work blocks less secure in comparison with auxiliar proof-of-work blocks i.e. malicious auxiliar miner will be able to fork native blocks out of the main chain*.

There is no way to calculate correct trust for so heterogenious chain. We can calculate a trust score for proof-of-work and native/auxiliar proof-of-stake blocks, but we can't make a correct difference between native and auxiliar proof-of-work.

Of course, we can fix a trust of auxiliar proof-of-work blocks at 1 or use another value but it makes no sense. Because such blocks wouldn't be able to provide any security into the block chain and native proof-of-work miner will be able to fork auxiliar blocks out of the main chain (direct opposite for * scenario).

So, we can't implement a sustainable PoS + PoW + AUX PoW system with separate aux and native difficulties. We have to use equal difficulties or remove native PoW to make PoS + AUX PoW design reliable. ::)

P.S. I guess that beta implementation of coin mixing protocol will be ready for testing in the near future.

The main argument is that balanced (proof-of-stake + proof-of-work) system is self-sufficient while (proof-of-stake + auxiliar proof-of-work) doesn't provide a self-sufficiency because it depends on stability of auxiliar chain. So we have to keep a support for native proof-of-work along with auxiliar proof-of-work to keep self-sufficiency.

I'm not convinced that we need to be self-sufficient. Look at the link I posted yesterday:

Quote
Basically here you mine one of the 5 main chain coins (LTC, DOGE, POT, CAT or DGC), and then get the other 4 (PTC, USC, ORG and HUC) for free, without loosing any performance. Furthermore, even if you are only mining LTC, you will get also DOGE, POT, CAT and DGC, just because the pool shares the ones that the others are mining with you. If you are mining at 1250Khash/s, it would look like this:

PesetaCoin: you are mining it at full speed, 1250Khash/s
UnitedScryptCoin: you are mining it at full speed, 1250Khash/s
OrgCoin: you are mining it at full speed, 1250Khash/s
HunterCoin: you are mining it at full speed, 1250Khash/s
LiteCoin: You are mining it at 250Khash/s (1250 / 5), even if the main coin you chose to main was other
DogeCoin: You are mining it at 250Khash/s (1250 / 5), even if the main coin you chose to main was other
CatCoin: You are mining it at 250Khash/s (1250 / 5), even if the main coin you chose to main was other
DigitalCoin: You are mining it at 250Khash/s (1250 / 5), even if the main coin you chose to main was other
PotCoin: You are mining it at 250Khash/s (1250 / 5), even if the main coin you chose to main was other

I haven't tried this, but it looks to me like the merge-mined coins do not rely on any particular main chain. If somebody can take down all of those coins at the same time then they can take NVC down as well, self-sufficient or not.

Self-sufficiency is nice, I agree, but it is expensive. I would like to be self-sufficient in food but it would be a fulltime job to achieve that. I'll rather buy my food at the supermarket and accept the small risk of starvation when all the supermarkets are closed.

Merge-mined coins do not rely on any particular main chain, it's true:

The child coin needs to be programmed to work with a SPECIFIC PARENT.  In this case USC (child) merge mines with LTC (parent) because that is the way USC was programmed.

I don't believe this to be true. USC does not care if a parent block comes from LTC or a similar copycat (with ChainID != 1, the only coin with ChainID == 1, is USC, other coins wanting to merge mined, should choose another ChainID). The reason is: USC does not know the genesis block of LTC, so it can't know if a block belongs to LTC. If no-one steps up to experiment, I will try to generate a block against an LTC clone.

The git repository contains the branch merged-mining. This branch is LTC + merged mining (starting at block INT_MAX, ChainID == 0). It can be a starting point for other developers to adopt merged mining as secondary chain.

Hmm that is a good point.  I hadn't considered that but looking both at USC code and NMC code I believe you are right it was an incorrect assumption on my part.  Since all SHA-256 coins use Bitcoin as parent I assumed that was encoded but it looks like it was not.  Would be interesting way to gain hashpower from many chains.   Obviously LTC is the biggest bang for the buck (10% of LTC network is worth a lot more than anyone else) but it may it does mean the coin isn't limited to the success of the parent as it can switch to whatever parent(s) are viable at the current time.  Thanks you helped me learn something today.

Another interesting idea (and it would be a little more complex probably requiring two different difficulty values) would be to create a coin which can use either hashing algorithm and support merge mining against chains with either algorithm.

Of course, but it depends on infrastructure of parent chain, which is used currently. DDoS attack or hacking against the parent chain mining pools is able to harm merged chains too.

Proof-of-work is required to be costly, that's why it's used in our design. We need a costly proof-of-work at the bootstrap stages, but that's not necessary in the long-term and it won't be required when the network will mature enough. Over time and the growth of the network, the role of proof-of-work will decrease... And once day it will become negligibly small on the proof-of-stake background. That's why we shouldn't care about energy-inefficient component of our system. ::)

EDIT: By the way, we are able to speed up the reaching of this point by increasing proof-of-work emission rate. I don't think that it's necessary but there is a proposal of proof-of-work target spacing change in order to simplify calculation of trust score and make confirmations faster.

P.S. Currently we are working on new block signing protocol approach, which is able to provide an additional security. This (https://bitcointalk.org/index.php?topic=143221.msg5254880#msg5254880) approach could be extended to handle proof-of-stake blocks as well as proof-of-work blocks. :)

every time i check the debug window the block numbers are not matching and it seems like the wallet is out of sync

when i restart it, it downloads the remaining blocks it seems like the wallet is not keeping up with the blocks

Good morning,

Looking at the charts on http://charts.novaco.in/ - Specifically the difficulty chart and the PoS difficulty...

It looks like PoS for NVC was "stable" prior to 5th of Feb, but now there is a major increase in d
