Finding p2pool networks.py values for new altcoins

[sheinsha]

hi again ... ok i am trying to setup a fastcoin pool ....  here are my settings..

Code:

fastcoin=math.Object(
        PARENT=networks.nets['fastcoin'],

        IDENTIFIER=''.decode('hex'),
        PREFIX=''.decode('hex'),
        P2P_PORT=50010,

        BOOTSTRAP_ADDRS=''.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-alt',
        VERSION_CHECK=lambda v: True,
    ),

Code:

        P2P_PREFIX='fbc0b6db'.decode('hex'),
        P2P_PORT=9526,
        ADDRESS_VERSION=96,
        RPC_PORT=9527,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'fastcoinaddress' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: 32*100000000 >> (height + 1)//2592000,
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        BLOCK_PERIOD=150,
        SYMBOL='FSC',
        CONF_FILE_FUNC=lambda: os.path.join(os.path.join(os.environ['APPDATA'], 'Fastcoin') if platform.system() == 'Windows' else os.path.expanduser('~/Library/Application Support/fastcoin/') if platform.system() == 'Darwin' else os.path.expanduser('~/.fastcoin'), 'fastcoin.conf'),

but i always get this error when i try to run on python

i hav setted up the pass and username. on python running code. but i always get this one

any ideas ?

Hi napoleon, have you got it to work? Im having the same errors...
Thanks!

[markm]

A lot of coins lately do not work out the block reward by simply dividing an original reward by a number of blocks, or like in bitcoin halve if every four years, so i expect for example the coins that use hashes of previous blocks to "randomly' decide the block reward (superblocks, lucky blocks, golden blocks) the python function for determining the block reward would need to do that exact same pseudorandom number calculations to match correctly the rewards the coin actually gives out?

Has that led to the coins that have lucky blocks being less likely to have p2pool pools due to p2pool coders maybe not wanting to correctly figure out those "random" rewards in python?

or maybe even has it led to p2pool pools for such coins tending to not figure out rewards correctly?

It doesn't address your errors but I noticed that you use for Fastcoin symbol FSC; it should be FST from my point of view.

https://bitcointalk.org/index.php?topic=218852.0

SYMBOL='FST',

Block period is 12s, isn't it?

BLOCK_PERIOD=12,

Your subsidy is not correct, it is not critical...

SUBSIDY_FUNC=lambda height: 32*100000000 >> (height)//2592000,

And this is not correct and could be troublemaker:

IDENTIFIER=''.decode('hex'),
PREFIX=''.decode('hex'),

Exactly, i think coins with random blocks must have their SUBSIDY_FUNC with same algorithm that the coind uses. But i cannot calculate the random part with p2pool, because it wont be the same (obviously) as the value calculated by the function in coind. So i can set it to always the normal block subsidy, but thats not correct.
Anyone know how luckycoin p2pool addresses this?? Ive seen the code, and lambda function states a fixed amount..

And this is not correct and could be troublemaker:

I was able to track down that error, and  made some progress setting the identifiers to something other than '', something like:
        IDENTIFIER='adc586a5dc685cad'.decode('hex'),
        PREFIX='ef39ae959feaf397'.decode('hex'),
These are random chars.. but now the error is gone, and the node seems to work fine. I dont know if this is the same issue you have and im pretty sure this identifiers will make this p2pool node unreachable to other nodes.. Im solo mining with this for my farm, so it wont bother to me. On another coin not fastcoin though..

Hope this helps !

this Block Explorer does not exist anymore and the new one does not provide Addresses and Blocks are in another format.
my p2pool runs on http://www.guugll.eu:10327/static/ but no payout - i am not p2pool pro/guru but i have the feeling none of the mined shares/blocks are submitted to the block chain - how could they and thus i get no payout - otherewise it would work like it did for Ahmed when the original Block Explorer was in place...

Please could any p2pool pro/guru correct me if i am wrong or help in case i am right... (we need the Block Explorer back)

[minerapia]

p2pool does not need a blockchain explorer for anything, its just used to create links to the p2pools webpage.
Cosmoscoin seems to have some sort of modified scrypt algo, so you need to customize the powhash fuction (make module for it) and prolly alter tx creation procedures, so its not so easy task (as modifiying network.py(s))

[guugll]

thx minerapia

this clarifies also the other errors i get and that was something related to tx message data not beeing handled well.

i am not able to do this mod so i will wait and learn...

[napoleon2121]

i hav lost my deticated for a month now couse of the costs. i will be back on the post in a few days i will add some more coins to github when i come also ty for the corrections on my scrypts

[guugll]

trying again PoS/PoW coin and again loosing...

using Baltazars p2pool: https://github.com/CryptoManiac/p2pool

the result looks like this: http://www.guugll.eu:15327/static/

if i mine with normal ORB address it does not look like its mining for me.
if i mine with hashed address then it look like its mining for me but i do not get anything(no payout).
after some time i get into error - to many open files on server and need to kill python(on server ubuntu 12.04).
i still not made any mods to the litecoin_scrypt but i tryed to make the newtork files again... (maybe this is the issue like in CMC case...above)

i used all info from this thread but still missing something, apart the posibility that the issues is in the litecoin_scrypt.
i am not able to compile new litecoin_scrypt :-(

ok Subsidy still wrong

so we have now this:

i am looking into this - had the same error before. but not sure how to fix it.

[guugll]

so this is not working SUBSIDY_FUNC=lambda height: .25*31000000 >> (height + 1)//1051200,
reward is 0.25
total should be 31000000
the nSubsidy from coin source is 1051200

and we need to make it work with this:

def get_subsidy(nCap, nMaxSubsidy, bnTarget):
    bnLowerBound = 0.01
    bnUpperBound = bnSubsidyLimit = nMaxSubsidy
    bnTargetLimit = 0x00000fffff000000000000000000000000000000000000000000000000000000

    while bnLowerBound + 0.01 <= bnUpperBound:
        bnMidValue = (bnLowerBound + bnUpperBound) / 2
        if pow(bnMidValue, nCap) * bnTargetLimit > pow(bnSubsidyLimit, nCap) * bnTarget:
            bnUpperBound = bnMidValue
        else:
            bnLowerBound = bnMidValue

    nSubsidy = round(bnMidValue, 2)

    if nSubsidy > bnMidValue:
        nSubsidy = nSubsidy - 0.01

    return int(nSubsidy * 1000000)

using this:

SUBSIDY_FUNC=lambda target: get_subsidy(6, 100, target),

or i need a sleep?

[minerapia]

SUBSIDY_FUNC=lambda height: 0.25*1000000 >> (height + 1)//1051200,
                                  so its  'block reward' * 'satoshies' >> (height + 1)//'height where block halves'.
                                                  

you only need get_subsudy func is theres some special way how the blocks rewards is calculated.

Does anyone find correct settings for FastCoin?

Is someone interested in making a p2pool for grandcoin ?
I dont want to mine solo all time. p2pool.org isn't working, other pools are crap :/

I tried to make my own p2pool but my linux skills seems to be to low

Hey guys, extremely useful thread here, got p2pool-altcoins up and running only by reading it here, thanks!

I am facing one issue tho, the pool keep disconnecting from the wallet, from time to time it takes a good 3 minutes disconnected. Is it due to the cheap *** vps I am using or this is the simptom of something else?

This is what its spits on the terminal:

Everything looks good but when I test mining on it I don't receive the block rewards, I get some few coins into the default address but nothing on the miners address, seems like the pool is not getting proper work from the wallet, or not what it expected.

Also the web interface trows this error every time I try to reload (F5) the page:

This also is very odd:

Code:

Could it be something with the block height or block calculation on the wallet?
Thanks!
