[ANN] Eloipool - FAST Python3 pool server software - GBT/stratum/dyntarget/proxy

[hodedowe]

For fun and as a soundboard I'll start posting my progress here. If anyone feels froggy please jump in, though I know this isn't that type of thread (support).

Moving on, it seems like the latest writeups all call for the process to be called "eloipool.py", but on my systems - and I've gone through several at this point trying to get it working - but all my systems run the process as "python3" so the killall scripts don't operate correctly.


As for errors, this one pops up all the time on the commandline after running : eloipool.py: no process found. I discovered this is due to newblock.sh trying to kill the process by calling it eloipool.py instead of python3. Fixed.

Now I'm still getting this error with the merklemaker:

Code:

And if I downgrade using the command in my previous post I get thousands of stale, bad, or discarded shares on the miner (see pic). So I'm back to going through this and trying to get it running. I'll post if I come up with a solution.


Got Stale? Check that "Rejected" vs "Accepted" - Ouch!

ALso, if someone has a copy of midstate.so and wouldn't mind sharing the code (cut,paste) I'd sure appreciate it as Gitorious is dead and not serving it anymore.

Running on Bitcoin testnet I keep getting this error when a test block is found

Code:

    raise RuntimeError('Failed to create usable template')
RuntimeError: Failed to create usable template

I believe it has to do with the difference in Test coins vs real coins. Trying to figure it out now...

[hodedowe]

Ok, successfully mined a test coin, but it failed to show up at the target address.
Good thing I'm on the test net and not shooting myself for missing 25 btc! 

[hodedowe]

In frustration I completely removed my eloipool installation and started from scratch using a different build and I'll be darned if it isn't working now. A few stales from time to time, but difficulty rises quickly and the bad shares are all gone. It's running fast and easy.

I'll continue testing this weekend. If all goes well I'll have a downloadable point-and-click version ready soon. Entirely n00b friendly.

[hodedowe]

Note: After mining several test blocks successfully it seems that the coinbaser address doesn't work, nor does the mining to the miner's address. The only address that receives coins is the TrackerAddr address in the config.py file.

[hodedowe]

I got a working version put together. I started a new thread here for support etc.

Good luck to anyone else looking to try to figure this out. It took me a while but it was worth it. All knowledge is priceless

[panyiqiang]

If TrackerAddr is not defined, will the bitcoind provide a generation address?How to estimate the current hashrate of the pool?

Segregated witness and SegNet are now supported in the "segwit" branch.
