Title: MAX COIN POOL BOUNTY (help fix stratum-mining) and start new pools!
Post by: cryptomind on February 08, 2014, 04:57:31 PM

Hello,

I started a new MaxCoin Pool (pool.max-coin.net) and everything is ready except one small issue.

All work done by miners is not counted in. The error in the shares table in the database says:

-> Share is above target. Hash: %s

All client shares sent to my stratum are not being accepted.

In a spirit of sharing, and helping us all get more MaxCoin pools for a healthier network, here are the full instructions on how I got the stratum-mining-maxcoin to actually work: http://pastebin.com/NZSKV0vQ

Can someone PLEASE assist.

I think one needs to replace ECDSA with Schnorr signing and use secp256r1 curve over secp256k1 (something I read somewhere on line) - alas I would not know where to begin.

THERE'S A BOUNTY FOR THIS from HashFaster: http://hashfaster.com/maxcoin-stratum-bounty-1-btc/

1BTC to anyone who gets a working public REPO on Git for this.

Please assist!

Thank you!

Taking a look at it ;)

EDIT : Damn, it's python!

Yea it is :)

Here's what I've done to get the stratum-mining-maxcoin actually running on Ubuntu 12.04:

Code:

 
# setting up the environment
        apt-get update
        apt-get upgrade
        apt-get install install git build-essential memcached libmemcached-dev mysql-client python-twisted python-mysqldb python-dev python-setuptools python-memcache python-simplejson python-setuptools postfix

        cd ../../ # <— exit back to  stratum-mining-maxcoin path
       
        cp conf/config_sample.py conf/config.py
       
        # edit the config file and change some settings
        nano conf/config.py

        twistd -ny launcher.tac # <— if debugging
        or
        twistd -y launcher.tac # <— if demonized (production)

Alas - the errors when I look at shares DB in the database show this:

Code:

*************************** 593. row ***************************
             id: 593
       rem_host: 210.86.28.6
       username: user.worker2

       solution: 0
     difficulty: 16
           time: 2014-02-08 03:56:37

It seems that a good number of other pools figured this out, however, none of them are sharing any info...

Looking at you RocketPool!

I started back my stratum server.

If you want to try sending work to it just to test, please just do the following:

minerd -a keccak -o stratum+tcp://stratum01.max-coin.net:3333 -u cryptomind.cloud -p 1 -t1

From the client I get:

Code:

People with wrong settings on cudaminer get a huge hashrate, but actually the miner is not mining (GPU load below 20%). Resulting on a pool with millions of invalid shares, Ddosing the db. If a botnet does that or multiple uisers the pools goesdown on I/o put through ---- my humble conclusion.

I am cpu mining in that example, cpu is being used, however, the shares are getting rejected...

We've heard from the guys with pools up & running that they have pushed their source to: https://github.com/Crypto-Expert/stratum-mining/tree/maxcoin. Hopefully you guys can use this to get some more online.

Title: Re: MAX COIN POOL BOUNTY (help fix stratum-mining) and start new pools!
Post by: Surgun on February 08, 2014, 05:46:26 PM

for right stratum do this:
git clone https://github.com/Crypto-Expert/stratum-mining.git
cd stratum-mining
git checkout maxcoin
update_submodules
cd externals/maxcoin-hash-python
python setup.py install
cd ../stratum
python setup.py install

OK, i I manually added these files (https://github.com/Crypto-Expert/stratum-mining/pull/239) and it works without an error too.

If you guys have miners - please join... I'm getting some hashes now! :)

Thanks

Post by: cryptomind on February 08, 2014, 10:48:30 PM

The only issues left now are:

1) Find a first block, so we know things are working correctly
2) Fix the hash rate display - people are mining at "supposedly" 400GH/s...

If anyone knows what's going on - please share :)

Thanks!

i tried both methods... this one and copying only the modified files... still no luck

I get the following from cgminer 3.7.2 for maxcoin

Rejected 01a3dc72 Diff 1/64 GPU 0 (global name 'sha256' is not

any ideas?

EDIT NVM I found it...

need to update from 'keccak' to

COINDAEMON_ALGO = 'max'

in config.py

I've tried doing...
---------------------------------------------------------
cd ~
git clone https://github.com/Crypto-Expert/stratum-mining.git stratum-mining-max
cd stratum-mining-max
git checkout maxcoin
./update_submodules
cd externals/maxcoin-hash-python
python setup.py install
cd ../stratum
python setup.py install

update the "autobahn.twisted.websocket import" line

cp sample config and edit it, using coin daemon as "max", wallet addy, rpc items, etc.

then running, twistd -ny launcher.tac from ~/stratum-mining-max
---------------------------------------------------------

but I'm getting the following...

Did you ever figure out the sha3_256 error? I'm getting the exact same thing. I've tried clean installs, different git repos, nothing.

Anyone else have a solution for the sha3_256 not defined error?
