MAX COIN POOL BOUNTY (help fix stratum-mining) and start new pools!

[cryptomind]

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!

[cryptomind]

Yea it is

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

Code:

        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 ***************************

       rem_host: 210.86.28.6

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

Looking at you RocketPool!

ypool drop support for MaxCoin, lol: https://twitter.com/ypool_net/statuses/432179313102696450

[cryptomind]

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.

[cryptomind]

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

DEBUG mining # cryptomind.be (0, 0, True, False, 1391880117) 1500.00% work_id(40f) job_id(17) diff(16.000000)

Taking a look at it  

EDIT : Damn, it's python!

do this in ruby

[maxcoinproject]

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.

[Surgun]

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

[cryptomind]

Deploying https://github.com/Crypto-Expert/stratum-mining/tree/maxcoin rite now. Will let you guys know how it works.

Probably a single step away from solution:

Any thoughts?

[cryptomind]

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

[Surgun]

maxcoin. tk is up.

[cryptomind]

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!

[Alphi]

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

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

[Hashturbater]

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...

2014-02-28 10:44:01,542 ERROR template_registry # [Failure instance: Traceback: <type 'exceptions.NameError'>: global name 'sha3_256' is not defined

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?
