Finding p2pool networks.py values for new altcoins

[Hyacin]

I've recently tried to port p2pool to some newer alt coins and have been hitting a brick wall. I'm pretty sure this going beyond basic network.py values but I wanted to get some opinions.

I've tried setting this up for grandcoin, lottocoin, luckycoin and earthcoin. The one I'm most interested in getting to work is earthcoin, so let's take that one for example. This is the error I receive when running it.

<snip>

Now, what I noticed is in the pack.py file, the functions
<snip>
is where the error is being thrown. The pos is always 1 character bigger then len(data) when the error is thrown. So setting the ignore_trailing=True eliminates the error, but when testing it against earthcoin, we hashed overnight and found a few blocks. However, none of them were actually committed to the blockchain and nothing was paid out. So I assume that is messing with the blocks submitted and they're not valid.

If you don't change that variable, the error that was mentioned is thrown for a while. Eventually it will connect to the wallet daemon, and you can actually hash in the pool, however the connection to the wallet will go unstable and the errors will start again. The connection to the wallet never really stabilizes.

Just for reference  here are my earthcoin network.py values.
<snip>

If anyone that has better python skills than me, and a better knowledge of how p2pool works cares to help, I'd greatly appreciate it. Like I said, I don't think this is isolated to earthcoin as I've seen this behavior with several new alt coins. Also, I've posted a bug report on the official p2pool github in case anyone wants to contribute.

Anyone have any updates/more information on this?  The bug report hasn't been updated in quite a while it appears.  I recall reading somewhere (probably this thread) that it has something to do with transaction comments in some coins.  I tried setting ignore_trailing to True as mentioned above, and that resolves my "Error getting work from bitcoind" errors, and p2pool will accept and work on block with transactions, but when they're solved it is unable to submit them ...

It retries a few times and then gives up.  I've switched back to solo mining right off the wallet (so, no merged  ) until I can figure this out, but I don't know where to begin, and half a day of reading everything I could find online hasn't yielded a solution

ok, I think I've got it looking for a comment now by modifying the transaction stuff in p2pool/data.py and p2pool/bitcoin/data.py, but now I'm getting EarlyEnd, I'm guessing when there isn't a comment present -

This I am not sure how to deal with.  If there are any python ninjas out there that could point me in the right direction that would be great.

I won't be around much for the weekend so a summary of my efforts so far in case anyone stumbles upon this and wants to have a crack at it or is already working on it -

p2pool/networks.py -

Code:

    grandcoin=math.Object(
        PARENT=networks.nets['grandcoin'],
        SHARE_PERIOD=15, # seconds
        CHAIN_LENGTH=24*60*60//10, # shares

        P2P_PORT=12377,
        MIN_TARGET=0,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=False,
        WORKER_PORT=19327,
        BOOTSTRAP_ADDRS=''.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-alt',
        VERSION_CHECK=lambda v: True,
    ),

p2pool/bitcoin/networks.py -

Code:

    grandcoin=math.Object(
        P2P_PREFIX='fdc1a5db'.decode('hex'),
        P2P_PORT=12377,
        ADDRESS_VERSION=97,
        RPC_PORT=12378,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'grandcoinaddress' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: 1000*100000000 >> (height + 1)//700800,
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        BLOCK_PERIOD=45, # s
        SYMBOL='GDC',
        CONF_FILE_FUNC=lambda: os.path.join(os.path.join(os.environ['APPDATA'], 'Grandcoin') if platform.system() == 'Windows' else os.path.expanduser('~/Library/Application Support/Grandcoin/') if platform.system() == 'Darwin' else os.path.expanduser('~/.grandcoin'), 'grandcoin.conf'),

        DUMB_SCRYPT_DIFF=2**16,
        DUST_THRESHOLD=1e8,
    ),

This alone of course yields LateEnd errors anytime work comes in with transactions due to the extra field (tx comment).


That error points to the unpack function in p2pool/util/pack.py where as already discussed in this thread, we can set ignore_trailing to True.  If we do that in both places it is set to False, p2pool will accept and work on blocks with transactions, but fails when trying to submit the solved block with -

I played around in helper.py with the submit function to no avail, so instead I went after the transaction format (realizing full well that this might break coins that do not have a transaction comment, including possibly the merged coins I am working on, but if I can get it working *with* comments, I can then figure out how to make it deal with stuff without comments) -

p2pool/data.py (search for lock_time) -

Code:

        gentx = dict(
            version=1,
            tx_ins=[dict(
                previous_output=None,
                sequence=None,
                script=share_data['coinbase'],
            )],
            tx_outs=[dict(value=amounts[script], script=script) for script in dests if amounts[script] or script == DONATION_SCRIPT] + [dict(
                value=0,
                script='\x6a\x28' + cls.get_ref_hash(net, share_info, ref_merkle_link) + pack.IntType(64).pack(last_txout_nonce),
            )],
            lock_time=0,
            txcomment=0,
        )

p2pool/bitcoin/data.py (search again for lock_time) -

Code:

tx_type = pack.ComposedType([
    ('version', pack.IntType(32)),
    ('tx_ins', pack.ListType(pack.ComposedType([
        ('previous_output', pack.PossiblyNoneType(dict(hash=0, index=2**32 - 1), pack.ComposedType([
            ('hash', pack.IntType(256)),
            ('index', pack.IntType(32)),
        ]))),
        ('script', pack.VarStrType()),
        ('sequence', pack.PossiblyNoneType(2**32 - 1, pack.IntType(32))),
    ]))),
    ('tx_outs', pack.ListType(pack.ComposedType([
        ('value', pack.IntType(64)),
        ('script', pack.VarStrType()),
    ]))),
    ('lock_time', pack.IntType(32)),
    ('txcomment', pack.IntType(256),
])

and this of lead me to the EarlyEnd in my previous post.  I also tried ('txcomment', pack.PossiblyNoneType(2**32 - 1, pack.IntType(256))), which lead to the same.

I did try a varstrtype for txcomment but that lead to some strange errors -

I realize it's a string in the grandcoin code, but I'm guessing and hoping it's converted to something else before it's sent over, if it's not I may be barking up the wrong tree though.  I also tried PossiblyNoneType/VarStrType and got the same AssertionError.

Any help, tips, pointers, code, genie wishes used towards this, online python tutorials, or anything else that could be of use would be GREATLY appreciated!

Hi,

I am trying to set up p2pool mining for the new crypto money called CrimeaCoin.
I tried connecting miners (CGMiner and SGminer) from my local computer and I am getting these error messages:

Hi all!  I am trying to start a p2pool for GPUCoin, got a lot father that i thought i might on the first night!  self teaching and doing this on a linux vps.

I am getting this error when launching the run_p2pool.py:

Would love to figure out what i am doing wrong. Thanks for the help!

You need to get the vertcoin p2pool code. Sorry I'm on mobile or I would post a link. Google will get you to the proper github fork for scrypt-n p2pool. Also, I'm pretty sure that fork already has settings for gpucoin. Good luck.

I'm getting this error when trying to start the DigitalCoin P2pool node:
Bitcoin version too old! Upgrade to v0.5 or newer!

Any ideas?

How do you create new sharechain for a coin?  I am trying to make a second chain for execoin (partially to learn how and partially to see if I can make it more friendly toward high intensity settings); however, from what I can tell, it is having issues because I don't have share chain (I am trying to run this inbetween two vm's) for either p2pool to connect to.  The code I am trying to use is:

Code:

execoin2=math.Object(
        PARENT=networks.nets['execoin'],
        SHARE_PERIOD=22, # seconds
        CHAIN_LENGTH=24*60*60//10, # shares
        REAL_CHAIN_LENGTH=24*60*60//10, # shares
        TARGET_LOOKBEHIND=200, # shares
        SPREAD=55, # blocks
        IDENTIFIER='657865636f696e65'.decode('hex'),
        PREFIX='65657865636f696e'.decode('hex'),
        P2P_PORT=25000,
        MIN_TARGET=4,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=True,
        WORKER_PORT=9173,
        BOOTSTRAP_ADDRS='216.249.119.195'.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-exe2',
        VERSION_CHECK=lambda v: True,
    ),

What are your thoughts?

How do you create new sharechain for a coin?

Change IDENTIFIER & PREFIX and delete the data directory. Although not necessary consider changing the P2P_PORT as well. Change persist to false(?).

I followed a guide on here to mine solo with an S1, it works perfect for BTC but when trying to mine another sha coin (frc) it returns the following:

"Couldn't link returned work's merkle root with its handler. This should only happen if this process was recently restarted!"

what would cause it?

Ok, I've changed the identifier to IDENTIFIER='657865636fe89f61'.decode('hex'), PREFIX='656578656398ed71'.decode('hex'), I've already changed the p2pool port (default is 9986).  I would like to have the share chain persist if possible.  Does it matter if I use a different announce channel or would it be beneficial if I used the default announce channel (#p2pool-exe)?  I also removed my execoin2 data directory, I am still getting code like this when I point a miner at one of the pools (if no miners are on the pool it looks fine, except that is doesn't display an entry for pool stats or shares)...

@CartmanSPC and everybody else

I am happy to say I got the exechain to work.  I am not yet 100% sure why it wasn't working before, but am planning to dig into it.  I was first using the zen2pool version of p2pool and am now using donSchoe's version of it.  I started the chain on a fresh vm and then connected to it with my other systems and it worked without a hitch (first vm started with persistant set to false and then added the others with true (not sure if this matters, but that is what I did)).

The code I used

Code:

execoin2=math.Object(
        PARENT=networks.nets['execoin'],
        SHARE_PERIOD=22, # seconds
        CHAIN_LENGTH=24*60*60//10, # shares
        REAL_CHAIN_LENGTH=24*60*60//10, # shares
        TARGET_LOOKBEHIND=200, # shares
        SPREAD=55, # blocks
        IDENTIFIER='657865636fe89f61'.decode('hex'),
        PREFIX='656578656398ed71'.decode('hex'),
        P2P_PORT=25000,
        MIN_TARGET=4,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=True,
        WORKER_PORT=9173,
        BOOTSTRAP_ADDRS='216.249.119.195 216.249.119.194 216.249.119.112'.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-exe2',
        VERSION_CHECK=lambda v: True,
    ),

I will report back later on how the results fair after I've had some more time to test it.  Your welcome to test it for your selves to see if the longer block time works better for your gpu's.  You can connect to any of my nodes (current bootstrap_addrs's) or make your own.

CartmanSPC, do you have an EXE address?

Thanks Doom4535. No need to send me anything...happy to help.

hey cartmanspc or anyone else who may be able to help. there is a 200k fuelcoin bounty out to help with the p2pool for fuel. i currently have the sharechain bootsrapped and am the only node for p2pool. so i would like to get everything working properly before more people start hopping on.

Hi all...

I'm the dev for 1Credit and YACCoin.  Started fooling around with hosting p2pools for each last night and it was pretty straight forward.  Thought everything was fine when I left at 3am - pools were hashing, 99.5% credits were being paid out (0.5% to the author), etc.

Looking at the web interface, I would see a single user - me, which was as I expected.

Per my coin log, around 7am this morning, while I was soundly asleep, something changed.  Instead of receiving 99.5% of the coins, I started ONLY receiving the 0.5% associated with discovering a block. The rest was going to a valid, but totally unknown, coin address.  I checked the /users webpage and for this:

http://puu.sh/acBhT/aed46ecb76.png


Those all appear to be valid YACCoin addresses, although I don't see any of them hashing in the p2pool log.  I have also not publicly advertised the pool (until now) nor the connection port, so am surprised by this.

Any thoughts?

FYI:  ADDRESS_VERSION is set to 31, which is correct for my coin, and matches the leading digit in those in the link above.

Possibly related:  I failed to find definitions for IDENTIFER and PREFIX and left those the same as in the litecoin.py?  Should I have randomized those to avoid coin conflicts?

Unrelated:  Can someone tell me what PERSIST does?  I had to set it to False to get things hashing...

Thanks in advance!
