[BBR] Boolberry: Privacy and Security - Guaranteed Since 2014

[crypto_zoidberg]

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.

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!

[crypto_zoidberg]

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

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.

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 ), 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 ?

not sure how to change intensity. thanks.

[clintar]

not sure how to change intensity. thanks.

It's just -i 18 on his gpu miner.

when will be add to bter?

I can push for it, but last I heard people wanted this to be delayed for a while

bter people? i think it wouldn't harm to have some more exchanges
push it

I cant believe BBR value only 1219BTC on the coinmarketcap

I cant believe BBR value only 1219BTC on the coinmarketcap

Just another transient market irrationality  . Most folks in this coin are not as vocal as say some others and good, honest true leaders need to shape the direction and marketing for the continued awareness of this great coin. There is now such a fine line between 1) good marketing and 2) "shilling". For a coin to succeed the first must occur naturally and second must be bare minimum. BBR seems to get the second one right. The first needs some help and it does look like there are new entrants which is always good.

@James, what is your personal opinion on new markets at this stage?

What? Who said that? I think BBR on Bter is a great idea. In fact, I am looking to build a chinese marketing team soon. So Bter is an important step in that.

If there is actually a sensible reason for this I'd love to know it. If we want to wait to make a coordinating marketing campaign around it that's one thing, but BBR needs more on exchange exposure, and I haven't heard about any coordinated marketing campaigns to promote the Bter addition, so I am a little confused as to why someone would be against it.

There will be updates to this very soon. We would love you and any others to be involved in future marketing projects.

Agreed.  I think that at this point, BBR would benefit from another big market -- if nothing else, because it might trigger additional volume from people taking advantage of arbitrage opportunities, both within BBR and across other currency pairs (by which I mostly mean the BBR/XMR ratio).  Nice coin.  Deserves some more love -- particularly after C_Z's most recent build that enables ring signature pruning.

That one alone should be trumpeted from the rooftops a bit.  Very solid technical progress.

btc-mike quit team, this doesnt look good anymore + messy thread and no real GPU info

Things have never been better here in BBR land.

Come back in a week and find out

If btc-mike quit the team, then it's not even a team anymore, right? Can you have a one-person team? That just sounds unfair (since a team implies competing versus other teams, who would presumably have more than one member).
