[ANN][BLC] Blakecoin Blake-256 for GPU/FPGA With Merged Mined Pools Stable Net

[SpeedDemon13]

I'm still getting 100% stales at 1.034GH/s with 0% GPU errors. Haven't got anything yet with the HD 5870.

because the diff is large

[mogrith]

I havn't gotten a new block in the past 6 hrs oddly my last 3 blocks have not yet completely confirmed either no change in the number of conformations in the last 2 hrs

[SpeedDemon13]

Finally mined 25 BLC @ 99.32% stale @ 1.097GH/s on the 5870.

Thanks I didn't make the miner however, I just paid smolen to cover the time it would take him to do it.

For the sake of exact wording of your offer and for the sake of russian tax laws! Not a big difference, the kernel is yours, but it was rather "copyright transfer", not "work for hire". BTW, in the software world, if you pay not for result but for time spent that time tend to become infinite

If the coin is a true sha256 you could in fact do with memory as low as 300 Mhz.

It's not sha256 but is very similar, the memory is almost unused.

Ok, I'll use 8227 as stated in the OP. I'm assuming that the stale are because of the getwork network, right?

High stales count was caused by my paranoia I made miner skip target filtering and submit every 1-diff share. Next release will filter  shares properly.

EDIT:
Disregard the line "(c) 2013, smolen" in blakecoin-reaper.cl, it should be "(c) Vorksholk" or whatever Vorksholk decide it to be. For my excuse, I still take all that crypto stuff as a hobby, not as a business

Ok, sounds great. Are you still developing the Quark miner also?

[smolen]

Ok, sounds great. Are you still developing the Quark miner also?

Yes, Smelter is in the work. With current rate and approaching end of Quark generation there is no much sense to improve Quark kernel, next release will come with minor kernel tweaks, reduced royalty rate and improved (I hope) host code. I'm hunting for Primecoin and want everything to be ready for release when that thing finally start work
Back to the topic - Blakecoin will not be put into Smelter or be included sometime very, very later w/o mining royalty. Potential conflict of interest and lack of time

XPM needs a good miner. Guess the problem with it is sieving is too fast with the current one. Blakecoin really needs a mining pool to offset the high diff, then mining will be better then solo. You might as well include Blakecoin with Smelter, just put an announcement that it has royalty fees in it.

yp - pool will help the coin. That's interesting: usually first pool appears faster than gpu\fpga miner for new hashing algorithms (correct me if I'm wrong  )

[SpeedDemon13]

So, is this the mining pool that is being worked on?

http://blc.coinmine.pl/index.php

[3dcgminer]

After another 24000 shares I got 2 blocks, 1 in 12000 shares at a difficulty between 2000 and 5000.
CPU load was 2%, GPU load was 99%.

We really need a pool, solo mining sucks.

[mogrith]

Got a block after 9 hrs aaannnnndddd it's an orphan 

Got a new 11hrs later we'll see

[Vorksholk]

Friendly reminder, when mining, you can get great stability with higher clockrates than you can with Litecoin/other Scrypt coins. Bump up that core +10% or +15% if you card can handle it, and bring down the memory clock to save electricity. For now, the higher hash rate is likely better (as coins are very cheap right now as far as computing power goes) but as time wears on, remember to reset to default clocks and undervolt if you are able to to conserve power and pay less per GH.

On another, similar note, difficulty seems to be scaling nicely. Has anyone else noticed that it tends to pick up particular values though?

[SpeedDemon13]

3 blocks in 24 hours, guess it's ok for the 5870. A mining pool would really help...lol

[atavacron]

I'm throwing 15GH/s at it and getting an average of 1 - 2 blocks and hour.  Oddly, between 8 - 9am every morning I get the most blocks.

My friends ( aka CryptoNewbs ) have various GPUs from 5xxx to 7xxx and are excited to find a couple of blocks a day.  It will be nice to eventually have BLC on an exchange for them to trade.

Go BLC!

[akabane]

Sometimes the wallet go to another chain (even with like 30 connected peers) and all found blocks get orphaned.
The only way to fix that is to restart the wallet.
Never have this kind of problem with other coins.

Does this issues is known ?

By the way: great job with blakecoin, I really enjoy the work which is done here

[SpeedDemon13]

I have been working on and have finished the Blakecoin wallet and Cpu miner.

http://www.blakecoin.org

Released yesterday but due the site being down I was not able to post on here until now:
https://forum.litecoin.net/index.php/topic,6280.0.html

Forked from Bitcoin reference wallet 0.8.5

Blakecoin Wallet is on Github
https://github.com/BlueDragon747/Blakecoin

Blake-256(optimized) faster than Scrypt and faster than SHA-256 in Sphlib C code

The algorithm was written as a candidate for SHA-3, Based on round one candidate code from the Sphlib 2.1 library and reduced the round function to 8 rounds.

Tweaks:
Removed some of the double hashing from the wallet relating to proof of work, No changes to the wallet ecdsa public/private key function that has proven to be secure for Bitcoin.

Block reward is 25 coin + inflation (square root of (difficulty + block height))
No halfing of reward after x blocks
Cap in place to reduce the difficulty jumps upwards
Block target time is 3 minutes and retargets every hour
7 Billion coins
Block maturity 120

The Cpu miner is on Github
https://github.com/BlueDragon747/cpuminer

CPU Miner Binaries:
Windows Intel compiled for core2+

blakecoin.conf example:

listen=1
gen=0
rpcallowip=127.0.0.1
rpcuser=username
rpcpassword=password
rpcport=8772
server=1
daemon=1
addnode=162.243.133.80
addnode=162.243.14.130
addnode=146.185.135.24
addnode=184.171.247.23

you can set gen to 1 or use the command: setgenerate true if you wanted to use build in mining(bit slower than minerd)

minerd command example:

minerd -o 127.0.0.1:8772 -O username:password -a blake -q -s 2 --no-longpoll --no-stratum

Happy mining  

Update:
Thanks to the efforts of kramble, Blakecoin has been successfully ported to the FPGA (early development)

FPGA-Blakecoin-Miner by kramble
https://github.com/kramble/FPGA-Blakecoin-Miner

For information an FPGA is not a SHA-256d Asic it is a re-programmable hardware device e.g a software defined hardware device used for hardware development and high speed custom logic.

Thanks to the efforts of Vorksholk and smolen, Blakecoin has been successfully ported to OpenCL on the GPU

http://blakecoinmining.com

Any update on the mining pool? Will you start having products and/or services connected to BLC? Will BLC be on a trading market any time soon? I suggest that everyone supporting BLC send support tickets to Cryptsy to get it on the trade market.

[Vorksholk]

24 GH/s seems to be averaging 1.3 blocks per hour.

[atavacron]

Yeah, it's definitely getting harder to find a block.  From 3:30am to 8:30am, I found nothing.

GPU 4.35GH/s, shares: 98094|4|98090, stale 100%, GPU errors: 0%, ~2.5847e+006 kH/s, 163002s
