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

[Luke-Jr]

I will help in the development of eloipool, but I do not know python very well (and certainly not as good as Luke) , for now  I can help in testing

is it ok that stratum server reports different  difficult than client? i have send You PM with detailed description of this issue.

Some clients display truncated bdiff (what bitcoin uses) instead of pdiff (what mining pools traditionally use). Pdiff 1 is about 0.9999 bdiff (and similar for higher difficulties), so truncating as bdiff will show 1 less than the actual difficulty.

BFGMiner uses truncated pdiff, so it will show these correctly.

Is the TrackerAddr a valid Bitcoin address.
Do 25 BTC of a solved block go on that address?

Ok, i'm trying to get eloipool with litecoin, and i'm getting this error:

How did you fix this?  I am getting the same error.  Thanks.

Eloipool doesn't support scamcoins like Litecoin.

If you're still getting the error anyway, it looks like it's probably from some ancient version of Python.
As the README clearly states, you need Python 3. To be more specific, I test under 3.1.

When I start ./eloipool.py I get the error that the jsonrpc module isn't found.

That means the bitcoinrpc module isn't installed correctly.

[tomaszsz]

this error still appears , just after starting the program,

is it a problem with configuration ? i use the same settings in the  previous version .

Check that all your option lists (especially TemplateSources, TemplateChecks, and BlockSubmissions) have commas after every element (including the last!).

that is true, a have add commas, and now

Probably your bitcoind is missing BIP 23 Proposal support.
There is a pull request for bitcoind here. It's also included in the 0.6.0.eligius and 0.8.0.eligius miner releases of bitcoind.
Alternatively, it should be safe to use Eloipool without any TemplateChecks. This is only used to guard against unknown bugs in block creation.

[tomaszsz]

everything look ok  now ( after comment TemplateChecks or  use  0.8.0.eligius  bitcoind branch )  but sometimes this message appears

Happens sometimes. bitcoind has found a new block, so is reporting our proposal stale. I'm assuming it's followed very quickly with a new block notification?

probably you dont have midstate module (compile this from source file midstate.so needed )
and no sql libs pymysql etc (install python modules)

You need to install the python3 psycopg2 module.

sudo apt-get install python3-psycopg2

or

sudo aptitude install python3-psycopg2

As this is the - interesting - open source backend.. Is there also an open source frontend based on this pool software and php / mysql ?

[Inaba]

Nope

lend me yours ;-)

ok i'll put something up when i got time...
