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

[BlueDragon747]

on win7 x64 it shows as "USB Serial Port" and in details its a FTDI device

"direct usb" is from the newer cgminer version 3.2+ so is not relevant it is a FTDI chip on the board

I use something like this for the cm1 dont use it for Lancelot as I prefer the python miner super stable for me
cgminer --disable-gpu --icarus-timing 2.45 -S \\.\COM7

Yep this is mine on linux (passwords redacted)

./cgminer -T --cainsmore-clock 195 --icarus-timing 1.0=20 -S /dev/ttyUSB0 --verbose --url stratum+tcp://eu1.blakecoin.com:3334 --userpass user.worker:password --failover-only --url localhost:8772 --userpass user:password 2>log.txt &

The -T runs it in "text" mode which I use since it's running as a background job. You may find you need this on windows too as this version of cgminer sometimes crashes with a curses error on startup.

--cainsmore-clock 195 sets the clock speed. You'll need to use this to get the best performance else it runs very slowly by default. Leave it out for now though as finding the right value takes some time.

The failover is for solo mining. You may want to put another pool in there.

As blue said, the python miner works well but it is a bit more difficult to set up (you need to install python, plus pyserial and json), then edit the blakeminer.py script to set your pool details. It only works with getwork though. It may be worth trying this if you can't get cgminer working.

I got it working at last with cgminer and thanks for the mcs file, makes it alot easier for me.

Couldnt find a donation adress but thanks for your hard work and support!

Great. Be sure to play with the --cainsmore-clock parameter to find the best speed (it only boots up to 50MHz). You'll probably be able to get between 180 and 200MHz before it starts giving HW errors. I see around 750MHash/sec poolside with 195.

Donations are welcome at BYEE2FvGv4L3yt5aEr8BQ73oWzXMu59Fwz (I really ought to put it in my sig I suppose). No need for anything up front, try it for a while then decide what you'd like to contribute.

I made an experimental change to the JTAG clock on the X6500, it may not work at all, but if it does then I'll see just how fast I can push it ...

https://www.dropbox.com/s/kft0qtlmdzr61f7/X6500-Robust-v07-t2-2core-155MHz-fmax-160MHz.bit

If it does work, then this one should overclock to 200MHz or more (the default clock is 155MHz).

fforforest: This one is not for the lancelot, so don't try it (it won't work and might damage it).

Hi just to share my mining experience:
mining with the CGminer 3.11 mod and a R9 290 GPU . Speed is about 2.8Gh/s. win 8.1 64 bit, 8Gb RAM, CPU (dualcore Celeron G1610) is running 50%
pool is eu1.blakecoin.com where now after many hours(due to the 140 Round Earnings confims needed) about every 3 hours > 10 Blakecoins start to drip into the 0.890 wallet.
so about 90 BLC per day.seems working smooth and GPU cool(due to the low 13 intensity?) .
R9 290 can run with Intensity 20 but CGminer 3.11 mod crasht when setting the intensity above the default 13 (which is more a 7950/7970 setting)

After an overnight run I see clock speeds of 150 and 166MHz. Pool side hashrate reads 480MHs.

I can obtain far higher hashrates and clock speeds, but MPBM clocks down the chips due to temperature. Even at the current low clock rates temps are at 34C.

Thanks for the report. The poolside hash is a bit disappointing, you should be getting 600 and 664MHash/s for those clock speeds. It's possible my interface code is dropping some hashes (I took the FIFO out when I did the initial build a few months back), but it shouldn't be that drastic a drop. I'll see if I can put it back in.

34C is nothing to worry about, the FPGAs will be fine up to 60C (heatsink temperature) which is about as hot as you can comfortably touch (as a quick check). It may be worth trying the X6500 mine.py as that lets you set the clock speed manually. I'd like to know how fast it will go before we get HW errors.

I love to try this coin mining.

Anyone has instruction how to compile miner on BAMT/SMOS distro?

I don't think anyone has ported Blake-256 to BAMT/SMOS distro yet 

You are welcome to be the first

I would love to be if I am able to.

I will keep visiting this thread in case someone decided to help. I love BAMT/SMOS because if I mess something up, I can quickly make another USB and my mining machine will be up again within few minutes instead of going through all the setup hassles again.

I keep on seeing BlakeCoin touted as Bitcoin 2.0 in some places. But why? It has been out for quite some time and would the average investor understand whats better? Could someone please explain to me what advantages it has and why it could be a darkhorse to rival bitcoin soon.

read this for an Introduction about Blakecoin

The Blake-256 algorithim is faster and same security than SHA-256D while using 3% less power and compared with Scrypt based coins is 14% less power on GPU, It is also on the FPGA thanks to the efforts of kramble and is 2x faster than SHA-256D without using any extra power and to put a cherry on top it is going to be merged mined at a pool level with other Blake-256 coins (pool can mine multi coins at same time e.g like BTC/NMC)

If Blake-256 had an ASIC built it would use less silicon space compared with SHA-256D ~40-50% and thus power so the chips would be cheaper to produce in volume making the ASIC based mining devices cheap not more expensive like you can see with Scrypt ASICs while using less power/silicon space at same manufacturing process (currently no ASIC has been made for the 8 round Blake-256)

The reward structure is also a more normal economic based system that should keep mining for a long time see here for some graphs thanks to Calhil

Also worth noting is the the higher the network hash rate the better the average block find time is on average this is due to the law of large numbers as the difficulty is set based on past random event (block find)

"rival bitcoin soon"
that is a very vague term a new technology can take 1-2 years to mature correctly and establish itself in the market

Interesting, can you elaborate on this?

The win wallet GUI sometimes says it's unsynced, why is that... you know with the green bar at the bottom which says "0 hours"?!

[BlueDragon747]

I am bit busy atm sry  

@Lyddite
Merge mining = like BTC/NMC

@rupy
QT Wallet losing sync = Boost Library issue fixed by using boost 1.55 for build (0.9.0 will use boost 1.55)

I'd love to mine BLC on my nvidia card with some sort of cudaminer. For us with nvidia cards, cgminer does not yield acceptable results.
Is it even possible to mine BLC with CUDA? Because if not, that might be the reason why no cudaminer exists yet...
