You really think he'll get that 10m onto an exchange before everybody panic sells and the price drops to 0 because he moved it? lol


I'm sure that he is more afraid of us to move the coins! because I think he know that he he moves 1 AUR everyone will panic sell!

I'm pretty sure that by now there are a few geeks that are monitoring all the addresses he made public and at his first try to move a coin every pool will stop mining so his transaction won't get  processed and panic sell will begin!

The delusions....



If you are really curious you should read the first 20 pages or so of this thread.  It's all been covered, people have raised the same questions you have and OP spent days early on answering.  Could he try to sell the pre-mine?  sure.  He might be able to get a few bitcoins in profit before someone noticed.  The wallets holding the premine are all listed in the OP.  Did you see what happened to PANDA when wolong started emptying the premine wallets?  Same thing *would* happen here.  Total up the standing buy orders on Cryptorush.  If you had just 2000 AUR to dump you'd take the price down to the .005 range and net about 11k USD.  As soon as coins start moving from the premine wallets everyone would know the airdrop was off and the coin value goes to 2 satoshis, just like PANDA.

My experiences mining this and other coins.


I have had mixed experiences mining with the various pools on this and other coins. This coin has suffered from quite a lot of DDOS attacks on the major pools which has been annoying. In fact it had become so irritating that I decided to go the P2Pool route instead. Again that proved a bit hit and miss with poor up time on various nodes and quite high latency at times.

I finally concluded that the best approach for me was to create my own personal P2Pool node - and wow has that made a difference. Payouts have been good, mining has been completely uninterrupted and by manually setting the diff for my miners I am making maximum use of their capacity.

My conclusion now is that for any new coin, even for first hour mining, I will simply setup and use my own P2Pool node and mine against that with my various miners.

I won't get in to the actual nuts and bolts on how to do it in this post, but here are a few tips I have picked up.

1. I subscribed to AWS and use their free tier virtual server to run my P2Pool node(s). Zero cost, quite low latency and excellent uptime.
2. I use Ubuntu ( any version will work).
3. To get it to work just download and compile the daemon version of the coin wallet you are mining
4. I used the detailed instructions available on setting up P2Pool for Dogecoin (lots of Google links) and just modified it for blackcoin.
5. One slightly technical tip - i did need to download the miniunpnp application to get the wallet to compile.

Hope this is of interest. Just to show you that you can escape reliance on pools and their frees with just a minimal amount of effort


yeah but how much hash power do you have?


Very modest hash power. Just 2 mh/s  - and even at that amount I find P2Pool works ok. But like many posts say, it does take about 24 hours for payouts to ramp up to full amount. It does not reward pool hopping - but then if you have your own node, why would you need to hop anywhere.

So you are basically solo mining through a local p2pool, right?  What is the advantage over just solo mining?

No not exactly. I am the only person connected to my P2Pool node but I am contributing the overall P2Pool hash rate for the coin. All the nodes combine together to form the overall pool. You can connect to any node in the pool and continue to receive your payouts.

The reason I start first hour mining in a P2Pool node is one of laziness really. In that first hour the overall pool hash rate might consist of just myself a few other miners - so in that sense  the rewards are similar to solo mining. However the difficulty quickly increases with new coins and my 2 mh/s would soon stop making enough coins to be profitable. But because I am already in a distributed pool the combined hash rate quickly increases as more P2Pool nodes join and more miners join those nodes. My rewards decrease of course but in a more gradual way without having the change pool and with no interruption to mining.

Thanks for writing that all out.  I'll have to test setting this up on another coin when there's no time crunch to see how it works first hand.

I don't understand.

Won't the airdrop of 10mAUR just crash the price? Currently AUR is trading for $25 with an AVAILABLE supply of what 100k?

so.. 100k /10.1m = .01

$25 x .01 = .25cents .... Huh?

Won't the airdrop just act as the fed printing money devalueing the current money supply?
Maybe somewhat.  They will be going to mostly crypto newbs though.  I guess it depends how many immediately sign up for an exchange and dump them.  If most get held it won't impact the trading on exchanges much.  It's a fascinating experiment, I can't wait to see how it turns out.

What do people think the airdrop claim rate needs to be to indicate success?  I'm thinking as low as 5% the first 30 days will be a positive sign it's getting traction.

Just bought in @888.

Thanks everybody!

Nice, I was aiming a little lower and missed out.  It bounced hard!

I still cant tell if proof of stake is working or not. I do not have a terribly huge amount of coins. The only thing I can seem to find is errors that say there was a duplicate proof of stake or that it failed on the proof of stake.

IE:

ERROR: CheckProofOfStake() : INFO: check kernel failed on coinstake 579b01ed6a8b44865af03f2329d84b851701468ec9ecfac8b8cdc73ea08424f2, hashProof=23dda075004ed2dfecfcf3000281757d8d35674bf03984ef9e14c6cfb9cbeb23

or

I can't tell if this is normal processing for PoS or if there is something wrong with the compile of the wallet.
Any clarification would be much appreciated.

did you search for "ThreadStakeMinter" ?
there should be a line in the debug.log which you appear to have open that says
Code:
ThreadStakeMinter started

yes, I'm looking more for an explanation of the errors. The duplicate I understand, but the kernal fail seems a little more serious. Considering outside of the stakminterstarted and these continuous errors there is no other mention to proof of stake in the debug log I'm wondering despite the stake minter running if there is an issue with the wallet compile.

i think it's ok.  it's flagged as an INFO type error which should be normal.  Searching kernel.cpp I found this:

Code:
return tx.DoS(1, error("CheckProofOfStake() : INFO: check kernel failed on coinstake %s, hashProof=%s", tx.GetHash().ToString().c_str(), 
hashProofOfStake.ToString().c_str())); // may occur during initial download or if behind on block chain sync

Left a fuckton of coins in the site wallet. I fucking hate my life.

Frontend seems overloaded, I am able to see it now but my auto-pay hasn't gone out yet.

How many can I mine per day with 750KH/s Huh

0,5 and less,difficulty goes up to sky !

Thanks. There's a boat I missed - I was under the impression that it would launch when they dropped them from the sky  Cheesy

People are saying that they will be dumped massively when the Icelanders get there share, but I don't see why. Many won't even be bothered to do anything at all with them. All that will happen is that the local geeks may try to buy a few of their neighbours.

I can see people using them for a lot of person to person exchanges.  Like I owe you $50 from last year, or one guy picks up the check at lunch and the rest each throw them an AUR.  Perfect for craigslist type transactions too.  Getting setup to turn the free AUR into actually currency is going to seem like a pain for the average person, I suspect a lot of them just circulate.

Guys how do we unlock the wallet?  Grin

Position the qt wallet near the middle of your screen.
Take a house key (car key may be too big)
Push your key into the lock icon near the bottom right of the wallet, may take significant pressure.
Once it's all the way in turn it 90 degrees to the left to unlock, to the right to relock.

HTH, feel free to tip  Grin

edit: sry, thought you were joking.  Johnny crypto posted the help below.

i dont actually know how to complile a wallet :-/

if you are on windows and concerned it's not 'staking' open up the debug.log and search for "stakeminting".  the file should be in the same folder as the wallet.dat and as long as you see that "ThreadStakeMinter started" line in the log you should be good I think.
52  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BlackCoin (BC) | on exchanges | scrypt | PoS | No premine on: February 28, 2014, 03:02:02 PM
not a aingle pos overnight  Huh   Embarrassed


My wallet is exactly like yours. I think the PoS generation only begins if you leave ALL balances UNTOUCHED for a minimum of 8 hours. If you transfer ANY coins in and out of the wallet, it resets the PoS 8 hour minimum count. I have been mining BC from day and have yet to receive any stake because I have been continuing to transfer coins in from mining. Even after the balance has remained untouched for at least 8 hours, the PoS generation is random and does not start right away.

Don't worry about transactions, my little stake showed up less than an hour after getting an autopayout from mining.

Also, I compiled a fresh copy of the wallet on a 2nd pc this moning and noticed theres now an icon that indicates if you are stake mining or not.  Little green arrow next to the network bars icon.  when I mouse over it says "Staking. Your weight is 0" (since there are no coins in this wallet.)

really mine says nothing like that...

I just grabbed the source off github maybe 45min ago.  getinfo returns this for version:
"version" : "v1.0.1-10-g9e563a0-dirty",

also, you can double check the debug.log for the StakeMinter output,

Code:
grep StakeMinter ./*
./debug.log:ThreadStakeMinter started

 got a link to the github one?

https://github.com/rat4/blackcoin

if you compiled with a 'git clone' to start for your current wallet you can just cd to the same directory, do

Code:
git stash
git pull
qmake
make

It'll remember the repo to use :-)  I always make a backup of the wallet while it's recompiling just in case it decides to overwite the original one.

http://bc.scryptominers.com/index.php - wtf is with this pool?

A whole lotta fuck up and no response.

Knowing Scryptominers it'll be solved eventually.
Did switch my owns systems to http://bc.hashfever.com/ however Smiley, just to be sure.

Double checck you account page on hashfever, I had tried to do a manual payout there yesterday and it never went.  Tried again today and my wallet address had been blanked out.  Filled it back in and got my BC right away.
57  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BlackCoin (BC) | Launched | scrypt | PoS | No premine on: February 28, 2014, 12:00:46 AM
I wish the dev would outline the PoS part in more detail.  As I understand  it the larger your wallet the higher your chances of hitting a PoS block?  Can those who post that they've received stake BC also mention how much they have in their wallets that are 8+ hrs old?  Who has the lowest amount but has received a stake reward?  11k here and no stake yet, on current wallet not encrypted so I think I'm all ready....
58  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BlackCoin (BC) | Launched | scrypt | PoS | No premine on: February 27, 2014, 04:12:17 PM
I tried greekpool, dedicated, scryptominers, coinz, all of them lose connection, and hash.so never failed me, 3 short disconnects since january. so, hash.so FTW

Trying hash.so now.  It seems like the majority of the total network hash is coming from outside the known pools.  I think the small miners would stand a better chance if we pour into a single pool and try to get a couple gh/s combined in one place.
59  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BlackCoin (BC) | Launched | scrypt | PoS | No premine on: February 27, 2014, 03:57:37 PM
Trying to mine this at the moment is brutal, nearly 50 GH/s , diff 400 and none of the 5 pools I'm trying to use seems to be all that stable.

Anyone know what I have to do to lower my invalid shares? Undecided Undecided

You can add --no-submit-stale in cgminer, I usually don't since they can get accepted as valid and the invalid shares don't really matter unless they are high enough to get your worker banned from the pool.  How bad is your invalid rate?  I think it has more to do with latency to the pool you are using than your local settings so it might be better to try a different one.
