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

[SpeedDemon13]

Will there be a mining pool any time soon? The difficulty is just too high to solo mine.

due to the changes that have been made it makes it hard for the pool server software to work out of the box its needs a new proof of work module for the Blake algorithm (done but not fully tested) and any sha256d hashing the pool server software uses needs to be replaced with Blake e.g sha256(sha256(data)) is now blake256(data), feeleep has been working on it but think that most of the others pool operators are waiting for p2pool for Blakecoin to be released or they want me to do it for them 

I did not premine and I am quite a small miner 20 cpu core and 2 FPGA's and the pool operators are unlikely to offer any donations for working on the problem even though they may charge you a % for mining with them so I am unsure how much work I want to put into getting their software working, I think that once p2pool is released that will solve the pool issue but I might help feeleep get a pool working as he has shown some effort to work on the problem unlike most others who expect me to solve it for them 

so my todo list looks like this:

1. p2pool
2. fix any small bugs and help feeleep
3. GPU miner

I have been working non stop past week so I am trying to get it done in a timely manner

maybe I should have done a pure clone coin would have been much less work 

sorry if I sound a little grumpy about pool stuff but got a lot of pm's demanding work from me which is unfair and I have not had much sleep past week or so 

No rush. Hope you get more people with the right skills to help you. I wish I could help out, but my only computer skills is Cisco Networking, computer troubleshooting and other IT networking related skills. This is pretty original, last type that is original is Scrypt-Jane.

thanks for kind words it always helps with motivation 

funny thing is that my degree is in Computer network management but due to lack of work in that area in UK I have mostly been working as a freelance games developer or network analyst   

Blakecoin is part of my hobbies as I enjoy working with electronics and c programs in my spare time 

I took a 6 class program in Cisco at my college that focused on WANs, LANs, Switches, Topologies of Network types (STP, OSPF, RIP2, etc) and more....I only have network certificate, but working on getting a BS in IT Networking, focusing on either Wireless or Security. I do freelance computer repairs, network setups and anything that I have a skill for in the field....

my advice is to move into doing Devops as pure networking is a dying industry with the pressure from cloud and visualization, Java/C/C#/PHP and other common programming languages are always worth getting the basics done it has helped me quite a bit having these skills 

you can get quite a few freelance jobs doing network security but expect things to be broken or already hacked by the time you get called in

Originally I was going to do more of the hardware aspect of networking, but security, wifi and virtualization is the future of networking industry. So, I made a switch towards that. I need to pick up my Java, PHP and C++ programming skills. I hear the nightmare of doing network security jobs. Previously admins purposely messing up the network before leaving and/or putting security holes to get back at their old company if they got fired.

I need the windows mining fpga app,this link is the code..

nope please look again its Python miner and works on windows
https://github.com/kramble/FPGA-Blakecoin-Miner/tree/master/MiningSoftware

I've just pushed up a new version of blakeminer.py which fixes a (minor) bug when running under windows (at least I think it does as I'm only testing on linux, but the script runs OK on windows now).

You need to install python version 2.7 from http://www.python.org/download (I'm using 2.7.3 on windows but the most recent 2.7.5 should be OK) , then install the dependencies as described in https://github.com/kramble/FPGA-Blakecoin-Miner/blob/master/MiningSoftware/README.txt and you should be good to go. Just check you set the correct COM port in blakeminer.py (and the username, password details), open a windows DOS prompt in the MiningSoftware folder (shift-right-click on it and select Open Command Window Here), then type "python blakeminer.py" (you may need the full path to the python executable, I'm not sure if the installer sets it in your PATH by default).

Best of luck

PS I did a 16 core build overnight, but the FMAX is only 21MHz so it will actually hash slower than the 12 core version (Xilinx ISE can be a real PITA to work with, it may days/weeks of trying different options to get a good result).

using python 2.7.4 here and python path is added was running just not any accepted yet will try the new version and report any issues but was running on windows 7 x64 without much fuss

Great, cheers. The bugfix just affected the checkblake call, which is just an info ... having lost a whole night's run a couple of days back due to using the wrong version of the script (ie without midstate), I added this as confirmation that the returned hash was valid (though it will usually be rejected by blakecoind since its a fixed diff=256 share). Anyway I've just done another push (was too hasty with the original bugfix, though this is an even more minor fix).

Got four blocks running overnight the lower diff helped enormously, back up to 85k now though

And try to get some sleep

no mining pro like the cg?

I have 4557 but keeping a close eye on it

confirmed sending Blakecoin is working correctly and is confirming fine. The difficulty is 186 atm and current block is 4577 so it all looks good

just make sure you update to 0.8.6 before sending any Blakecoin's

any issues with sync rebuild your block chain data (backup your wallet first just in case)

[Vorksholk]

0.8.6 seems to be working great.

On another note... difficulty above equivalent 120000 for pre-0.8.6 difficulty calculation. :O

[UMP-45]

Are you going to release a GPU mining software soon?

[Vorksholk]

I wonder how much mtrlt would charge to do a Blakecoin version of reaper....

[dna_gym]

What's the point of this coin? It is neither asic-resistant nor gpu-resistant.
Is the strength of this coin an efficient cryptographic hashing function?
I wonder if an inflational fork will succeed in the future.

[BlueDragon747]

Are you going to release a GPU mining software soon?

yes the OpenCL is on my Github but just need some time to work on the miner, but finishing p2pool first

my todo list looks like this:

1. p2pool
2. fix any small bugs and help feeleep
3. GPU miner
4. try and fix any build issues on Linux and Windows

Blakecoin is fast and efficient and more on par with Bitcoin than any other Alt coin yet

1. No current SHA-256d Asic will work with Blakecoin so it is resistant it that sense, you would need to develop a new Blake-256 ASIC and as I have said before you are best off with FPGA if you wanted power efficiency. FPGA's also have a resale value as they are re-programmable! 
2. Why would you want to be GPU resistant did it work for Litecoin?
3. The strength of the Blake-256 hashing function is far more than needed 2^192 at least, it is also more efficient than SHA-256 

I think a small amount of inflation like what Blakecoin uses will help miner's who invest by buying or using equipment to mine Blakecoin so that over a period of time you can get your ROI, I see no good coming from cutting the subsidy it only makes it harder to plan a return on your investment. Also atm the inflation is so small it might be some years before it significantly adds to the base subsidy

Note that the inflation in Blakecoin is not fixed it is directly related to block height and the current difficulty 

[Aalesund]

GPU miner and p2pool will come soon?
For me it's impossible solo mining with CPU.

[BlueDragon747]

GPU miner and p2pool will come soon?
For me it's impossible solo mining with CPU.

p2pool has build issues on window atm and on Linux have only just started testing and is not fit for release yet, will continue to work on it once I get a few nodes working and shares paid I will do a release 

on the GPU miner side of things I have only had a brief look but would like to add it to bfgminer but if I get any build issues I will just extend the CPU miner to use OpenCL and the blake256.cl kernel, I could also mod poclbm to use blake256.cl but I am not so sure about reaper does not look that good 

will get something done this week for sure 

[bronan]

Well after 6 days (almost 7 days now) mining with 3 x 8 core cpu's i give up with 0,0000000000 blocks found

My i7 3770k + amd fx8320 and my E5-2690 have not found 1 accepted single block

Yes i got many unconfirmed but all of them disappeared

Its ammazing that i see almost every 10 minutes a new block being found, however non are being found by anyone other then those special people getting them all

I still have the enormous amount of 12.5 coins which i got from the give aways

I try not to think how much the price in electra it has cost me, but it will not be pretty
