Have any of your heard the Buzz about Stealth Coin? I'm still a staunch supporter of Boolberry, and am holding and mining the coin, but I'd like to get the communities opinion about what I've read over on the Stealth coin forum. Here is what there saying about Boolberry and Monero.


"StealthCoin will implement (Sublinear signatures) "Chandran Signatures"  - this is ring signatures WITHOUT the block chain bloat                                                        
Ring signatures provide TRUE anoniminity - there is no doubt about that - but they suffer from bloating the block chain - this is why sublinear signatures are a good way to do anon - but wihout the bloat. Ring Signature coins (Crypto Note Coins) are not feasible for high volume transactions - the chain would grow to large to fast if people started using it like bitcoin or litecoin is used - Stealthcoin wont have this problem - which means stealthcoin could handle VISA or Mastercard type volume without being bloated out to butt fuck no where                                                        

Chandran signatures are square root in size - so it means that a 36KB ring signature now becomes a 4KB Chandran signature - means less space eaten on the block chain (faster synch times etc.) Crypto Note coins are impractical due to the large space requirements - this is why stealth will utilize "Sub linear Signatures" or "Chandran signatures" and be immune to the bloat - it allows to handle bitcoin volume like transactions. Chandran signatures (sublinear signatures) were conceptualized at UCLA (they are a real thing that DOES work) - stealth coin will be the FIRST coin to implant such thing                                                        
                                                        
BBR (Boolberry) was close to solving the bloat problem by pruning and expiring signatures - but this is not the optimal way to do it - "Chandran" SubLinear signatures is the PROPER and optimal way to do it - by means that the signatures themselves will no consume near the space - so no need to prune                                                    

AND THAT'S WHY XST WILL SEE AT LEAST A 10m MARKETCAP. THIS IS JUST THE BEGINING.




What does this mean? I'd love to hear your options on this?HuhHuh

At first, as i know, "Chandran signatures" will be slower(algorithmically) than CryptoNote ring signatures, so it's hard to talk about visa or mastercard volume.

Second, as i also read - there need trusted setup.(common reference string model,  http://research.microsoft.com/en-us/um/people/nichandr/ringsignaturessublinear.pdf)

Third even if they have less size RS - it's still not the same as zero size of pruned RS in Boolberry blockchain.


Anyway, i think this is interested project and will keep watching progress.

Hey guys, have a problem. I have the latest wallet and i'm missing coins!
This is my address:  1Ha56YSPtSDjSiMMG1LxTV8VAX4z8Qz8xe3LSZc7eEgThCo11jQGYrqGN29QSSvdMCCgKjDAKKBkAX5 6taXwH2TVSHjZwv5

This is what the wallet is showing: Balance: 2.999998000000 Unlocked: 1.999999000000

I had 1000 BBR back at the end of may. In June it shows I added 104 more BBR. I haven't touched my wallet or made any transactions since then and now i'm down to 2.99 BBR as my balance? What happened?
I tried restoring the wallet and opening it up on another computer but that didn't help.
Any ideas?

Do you see that transfers in history?
What wallet version you have?

I wasn't really trying to troll (I guess it's just in my nature Tongue ), but I've never seen BitCrea post anything or chat on IRC. Just checked and saw that he/she is listed in the op, along with btc-mike (still). Also, I do own some bbr. Sorry for commenting and bumping the thread, please return to your regularly scheduled circle jerk.

I could understand why you think so.
But Bitcrea's work is not related in posting here, we talk in skype almost every day (i prefer skype to irc) and he is pretty active in our project, and i guess tifozi could confirm it since he also often in our skype chat.

Clintar, thank you for understanding, atm i moved your pool to last position in pool's list. Let's see how it's going. Another move that we can do - is to exclude you from list for few days to spread hashrate around other pools, only in case if you don't mind.


Nope, I don't mind. How do you like my proposal for the round robin dns idea? Downside is it having to be maintained by you. I guess pools could host their own with their own server as priority, too, in case someone wants to mine at a certain pool and have failover.

I like it much(exept thing that i have to maintain it Smiley), good idea, and it definitely some new approach. Since you seems to be trusted person for me and for community, i would be happy to see you as maintainer of this, what you think ?  I really have a lot of stuff last days, even have not enough time to code.

btw: i wrote you in irc, did you saw it ?

Nice, looks good. Sounds like I should change some diffs, then, too .Smiley

http://cncoin.farm/

Network
 Hash Rate: 7.29 GH/sec
 Block Found: 2 minutes ago

Our Pool
 Hash Rate: 3.51 GH/sec
 Block Found: 2 minutes ago

Right now BBR is getting itself into a bad situation for multiple reasons.. Besides the 51% attack, a DDOS attack @ http://cncoin.farm/ and mining BBR becomes *extremely* profitable for an attacker.

I was wondering what I can do about that. Probably need miners to fail-over at least. If pools had standard ports, I was wondering if a round-robin dns with all of them listed would work out ok. Otherwise I guess I can set a really high fee to get people to switch when it's so high, but I'd sure look greedy doing that with so much of the network.

Clintar, thank you for understanding, atm i moved your pool to last position in pool's list. Let's see how it's going. Another move that we can do - is to exclude you from list for few days to spread hashrate around other pools, only in case if you don't mind.

MBK's Boolberry Mining Pool

I've spend a lot of time optimizing OpenCL miner so later I looked at how pools work too. Clintar fixed the problems so pools work much better now if updated. Anyway I have some ideas how to tune the pool to get more blocks on the same hardware. I tested it for a week with my GPU farm, rented a decent server and now you can give my pool a try.

http://bbr.mbkpool.info

Usage with my OpenCL miner:
Windows
Code:
minerd.exe -a wildkeccak_ocl -o stratum+tcp://bbr.mbkpool.info:7777 -u YOUR_WALLET_ADDRESS -p x -k http://bbr.mbkpool.info/scratchpad.bin -l scratchpad.bin 
Linux
Code:
minerd -a wildkeccak_ocl -o stratum+tcp://bbr.mbkpool.info:7777 -u YOUR_WALLET_ADDRESS -p x -k http://bbr.mbkpool.info/scratchpad.bin -l ~/scratchpad.bin 

Changes:
  • 100ms boolbd daemon polling interval - to get new blocks as soon as possible (later I could make it even less)
  • 1 minute difficulty targeting - it's better to make shares rarer and more valuable in current miner implementation (starting diff is 150 millions on port 9999 for multi-GPUs)

Options to try:
-i x (intensity) - default value is 18, try lower values if it doesn't lower your hashrate as it will improve efficiency (we cannot exit GPU calculation cycle so the shorter cycle means less time we lose when new block arrives)

I'm not talking about large improvement but the miners should be close to 100% efficiency. You can try it and make decision yourself. Look at miner's output and compare. In the real example below the miner calculates 1112 kh/s and every hash works to make a share on the pool.
Code:
[2014-09-10 21:56:40.175] eff: 100% @ 1112 kh/s, accepted: 1251/1251 (100.00%), 1101 kh/s at diff 76695845 (yay!!!)

Added! Thank you!

The spending of the multisig output is the point at which the funds become spent by the group and respendable by the new owner.
how to determine that someone has spent a transaction? apart from a transaction itself being spend, is it possible to determine if a transaction was spent by a specific address viewing only the blockchain? or can it only be understood that the tx has not been respent yet, which can require the forced mixin?

aside, can the chain be parsed in order to determine only that a transaction has been spent, when another transaction attempting to mixin with it is completed. if someone mixed with a previous multisig tx, is it possible to determine that that multisig tx was spent, ie: invalid for mixing?

.....

I'm not sure if i understand your post corret, i only want to point that you can't see addresses in blockchain, and you can't say on which address was sent transaction (except in the case when you have tracking key of recipient address), since CN blockchain don't have addresses in it.

TY, Dr!

This makes a lot of sense Cheesy

Are you thinking about using multisig?

Yes, i'm thinking about this, but it's pretty questionable if it really usable ? Bytecoin implemented it, and seems that didn't get much attention or usage.

What do you think ?

It's important, but the version with no ring sigs is a disappointment. Some cryptography improvements are needed to do it right.


Can you clarify ? with something more than vague phrases

Another great addition should be a database. Are there plans of implementing that yet?

Yes sure, database is important milestone.
I was actually curiouse if Monero devs finally gona release it? Because it's pretty boring work, and i'm not really want to do it myself:)
433  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [BBR] Boolberry: Privacy and Security - Guaranteed[Bittrex/Poloniex]GPU Released on: September 09, 2014, 08:55:57 PM

This won't affect mixing since we will still have ring signatures above this block going forward correct?
You can mixin with transactions that is as under checkoint as after checkpoin - no difference, it's not affect. Any of them still could be usen for mixin.


Can it be detected that they were mixins from the part of the blockchain that was pruned or no? Do you have more detailed information about your transaction structure?

I can't make much information from your nice powerpoints, sorry.

Transactions that lay before checkpoins and have pruned ring signatures could be spent, or could be not spent yet. No matter.
I have very similar transaction structure, and it refferes to other transaction's outputs with the same way as any CN - amount + index. So you know exactly from wich transaction your input's selected for mixins.
So answering to your question - yes, it may be detected, and there is no difference since both part of blockchain contatin as spent transactions, as unspent.

This is great work! 

I checked the blockchain file size before I updated and after. This trimmed 4.075977% off of the blockchain on my computer.  It was actually more because I hadn't synced for a day or two before I updated and resynced the blockchain.  BBR already synced faster than the other CN coins and this will just make it that much faster and more usable.  I can't wait to see what future developments you come up with crypto_zoidberg.  Advances in the implementation of the Cryptonote technology like this are the reason that BBR IS the BEST Cryptonote coin.  You have made more significant changes to the original codebase than any other implementation of CN.  It's only a matter of time before that becomes a well known fact within the crypto community and BBR takes its rightful place as the leader among Cryptonote coins. 

You deserve some kind of recognition for your hard work so I'm donating another 500 BBR to your dev fund.  BBR transaction# 682e5ea5c373bc8f877189d3b0632c580a384135f8818fd53d6ca5fab417db4c

Keep up the good work!


Blockchain with release "bbr-win-x64-v0.2.0.37(ceecfdf)":




Blockchain after updating to version "bbr-win-x64-v0.3.0.38(109f49c)":



I feel that i need to clarify a little here.
First - as i said before - pruning transactions will make significant effect for those part of blockchain that have pretty much transactions in it. Early blockchain consist mostly from coinbase transactions that is not affected(coinbase transaction doesn't have ring signatures). But anyway, there more that 8000 usual transactions in first 70000 blocks.

Second, blockchain.bin is not simple blockchain. When daemon receive blocks with transactions it build from this data special database in memory, there tons of helpful information that is used to verify blocks and transactions and to handle currency rules: global outputs index (that is used to refering in transactions inputs ), transactions database, some information related with each block(such as cumulative difficulty, scratchpad offeset, block cumulative size, emitted coins, etc), blocks by id database, spent keyimages, finally scratchpad. 
All this information is serizlised (dumped)  into this file (blockchain.bin), so it is obvious that there some huge data overhead. So actually summary blocks + transactions size is not so big, hard to say exact numbers, x times less. And this is another reason why you see not much difference - since ringsignatures is actually ballast it is not used in other data model, and after pruning it data model stay almost the same.

Main benefit from this feature is decrease traffic usage(actuall data amount that transfered between syncronizing nodes under checkpoints get significant decrease), and some times (when synchronizing reduced by bandwidth) - speed up synchronyzing.



435  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [BBR] Boolberry: Privacy and Security - Guaranteed[Bittrex/Poloniex]GPU Released on: September 09, 2014, 08:05:53 PM
So with pruning the ring signatures below block 70000 this will keep the size of the blockchain smaller?
Blockchain will be smaller, but mostly it will be seen on those parts of blockchain that contain more transactions, early blockchain consist mostly from coinbase transactions that are not affected.

This won't affect mixing since we will still have ring signatures above this block going forward correct?
You can mixin with transactions that is as under checkoint as after checkpoin - no difference, it's not affect. Any of them still could be usen for mixin.

So in the future will pruning be done again? If so is there going to be some type of schedule like every 70k blocks?
I hope I'm understanding this correctly. Please correct me if I'm not.

Frankly, i was thinking to start pruning transactions after first year of currecy live, since it's not really significant effect from this feature for early blockchain where most of transactions is coinbase. But few my friends suggested me that some people think that our features is fake and it would be better to demonstrate it in real work. So enabled this feature and it's seems to be working now.
I think i'll be doing pruning every 6 mounth.

Good news!

We have a new build v0.3.0.38(109f49c), where we finally started to prune ring signatures.

What is going on ?
New build prune ring signatures in all transactions that lay under height 70000 (new checkpoint).
When you launch new version, you could see that message(numbers would be little different):



How does it work:

1. When new version (v0.3.x, build 38 and older ) load blockchain from drive, it prune signatures from transactions under chekpoints after storage loaded from drive and before core start work.
2. When new version (v0.3.x, build 38 and older ) download blockchain via network from older clients (v0.2.x, build 37 and younger) it downloads full blockchain and prune transactions locally before put it into the storage.
3. When new version (v0.3.x, build 38 and older ) download blockchain via network from the clients with version v0.3.x it downloads blockchain with pruned ring signatures.
4. When old version (v0.2.x, build 37 and younger) will try to sync with client (v0.3.x) starting from height higher then 70000 (less than ~17 days ago) it will successfully synchronized
5. When old version (v0.2.x, build 37 and younger) will try to fully download blockchain from scratch from new clients (v0.3.x) they fail to do it, so you need to use new client. Or manually download scratchpad from website.
6. On handshake both peers figure out what checkoint height has other party, and consider it to figure out if synchronization is possible. If you see such messages in logs that also means that you have old version and should update your client. But it still work's properly.

Now, when new clients download blockchain via network from versions v0.3.x it looks like this:




Important: If you have version v0.2.x and by some reasons can't/don't want to update it to v0.3.x, and have to synchronize your client from height under 70000, you better to pre-download blockchain from website:
Windows blockchain: http://boolberry.com/downloads/windows/blockchain.bin
Linux blockchain: http://boolberry.com/downloads/linux/blockchain.bin

Well, we tested it, but it's still possible to have bugs, so i won't push update alerts for next few hours to collect feedback.
Let me know is something is going wrong.


Good luck!

Can't send the coins, it shows "failed to send transactions : transaction was rejected by daemon". It works fine a few days ago and I already updated to 0.2.0.37 and deleted the boolb folder in roaming folder


Please, send me logs from daemon and wallet (if you use CLI) or logs from qt-boolb.log if you use GUI to crypto.zoidberg($)gmail.com

For me it doen't looks like a developers's driven project. If developers was just hired to create technology, than they are not responsible for... say ..strange marketing ? Isn't it ? Questionable.
It's just my guess.

Sorry but why are you defending a 82% pre-mined fake blockchain like its an innocent marketing mistake, were the crippled miners too? I doubt the guys behind the CN (genius work) had to put up with incompetent market leadership and were "forced" to launch such DOA coin.

I'm not defending anyone. I've just said that i guess that developers are usually hired people that paid for doing the work.

I'm defending technology.

439  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 07, 2014, 04:09:05 AM
....

- I understand it is hard to swallow my text. Perhaps it was too harsh. I try to tone down. I've had a lot of stress lately.

- I admire the CN team's work. The implementation of the world's first functioning anonymous coin tech is a marvellous achievement.

- Now comes the sad part. I think most of the team participated in a scam, and that's why I call them scammers. The BCN coin was said to be 2 years old, but that is a lie. Whoever says that but knows better is a liar. Not good. I am not buying coins from liars or scammers.

For me it doen't looks like a developers's driven project. If developers was just hired to create technology, than they are not responsible for... say ..strange marketing ? Isn't it ? Questionable.
It's just my guess.

All i want to say is that technology and way it is used are two different things.

Technology is opened and transparent. It's not messy - all you need is strong exprience with modern C++ design, passion and maybe little different attitude to it. (not you personally sure Smiley
It's not only my opinion - for example i have another dev who was helped me with some core patches (difficulty adjustment from 64 to 128 bit to be more concrete) - he also gave good feedback about codebase. And also it said dga (Dave Andersen) if i'm not mistaken (correct me if i wrong).


But still - lack of comments in code is a problem for thirdparty developers. I would like to fix this issue but for me is faster to write in C++ than in English language Smiley I guess it's obvious.

....
- I believe now would be a time for a great reconciliation. CryptoNote tech is better than the alternatives, and having someone from the original team working on Monero would be great. It is just that all evil things, scams, malice etc. must be left behind.


Totaly agree with you.


440  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency (mandatory upgrade) on: September 07, 2014, 12:32:02 AM
W h a t   a   g r o s s   i r o n y that the most legitimate and economic initial distribution of any cryptocoin existing (and therefore the most potential #2 coin in the months and years to come) happens to be a coin with an unbelievably messy codebase, intentionally made scammy, buggy, unoptimized, crippled and obfuscated by the (B)CN scamdevs.


It's not irony. It's misunderstanding.
You probably was confused when someone convinced you to invest money into CN-based project(or you decided it by yourself) - this is not bitcoin-fork with mature life cycle, this is brand new, developed from scrach software that has a lot of work ahead. Every one who at least little familiar with software development should realize what does it mean, esspecially for software related with security. The problem is that you've missed this fact.

And after an about half year of public run there was found first critical bug that was unfortunately used to exploit with Monero network... (and this is sad, i could understand stress that was felt by all involved in xmr people), but this quality indicator many many times higher than bitcoin development has.
Yeah, it's yet enother good chance to blame CryptoNote devs, but i really doubt that any of XMR devs had done their own cryptocurrency, written from scratch and worked fine. (okay, almost fine  Wink ).

The only problem of CryptoNote codebase is that it's undocumented and don't have comments in code... well, that's true. But this is very different from "unbelievably messy codebase intentionally made scammy, buggy, unoptimized". (And don't take into account CryptoNight PoW hash function since it was really suspicious code, and i also agree about C-code, never understood why people use "C" when this is potentialy buggy language? ).

Compared Bitcoin-based projects and CryptoNote technology it's the same as compare say "ford focus", that is good well-known car, and Tesla-prototype, that has bright ideas, a lot of work behind it, but still not perfect, without instructions and documentations, with a lot of work ahead and unfortunaley with some new bugs there.

So it is not a CN fail, it was just your own choice. That i believe is good choice.


PS: I didn't meant that current Tesla is buggy and without instructions and documentation - i used it jusе as an example of something new.


Just my 2 satosi. Sorry for late post.
