p2pool networks.py altcoins

[airborne305]

Hi, i started my journey into the coinworld by pretty much diving straight into the pool side of things. i've pretty much compiled and hosted every coin on a cloud VM for testing. i consider myself a noob in all of this still.

one of my hangups when launching a pool, is i find myself having to wait for somebody else to modify p2pool for whichever altcoin. i would like to get past this hurdle. i have snooped around all of the source files and readmes for whichever coins and have only been able to come up with a fraction of a fraction of the information.

would anybody be willing to explain how, why, where, and what the required information below comes from/means? share your process or formulas for coming up with the numbers and addresses.

i imagine this would be useful for other pool backends as well.   

p2pool > networks.py - Terracoin

Code:

 terracoin=math.Object(
        PARENT=networks.nets['terracoin'],
        SHARE_PERIOD=30, # seconds
        CHAIN_LENGTH=24*60*60//30, # shares
        REAL_CHAIN_LENGTH=24*60*60//30, # shares
        TARGET_LOOKBEHIND=200, # shares
        SPREAD=15, # blocks
        IDENTIFIER='a41b2356a1b7d35e'.decode('hex'),
        PREFIX='5623b62178d2b8a3'.decode('hex'),
        P2P_PORT=9323,
        MIN_TARGET=0,
        MAX_TARGET=2**256//2**32 - 1,
        PERSIST=True,
        WORKER_PORT=9322,
        BOOTSTRAP_ADDRS='seed1.p2pool.terracoin.org seed2.p2pool.terracoin.org forre.st vps.forre.st 93.97.192.93 66.90.73.83 67.83.108.0 219.84.64.174 24.167.17.248 109.74.195.142 83.211.86.49 94.23.34.145 168.7.116.243 94.174.40.189:9344 89.79.79.195 portals94.ns01.us'.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-alt',
        VERSION_CHECK=lambda v: True,

thanks for your time in advance.

You also need to check the file
p2pool/bitcoin/networks.py

Nearly all of the variables there are p2pool specific. my comments are in {}, I know some of them but not all of them.

SHARE_PERIOD=30, # seconds {difficulty is adjusted such that p2pool shares are found this often}

CHAIN_LENGTH=24*60*60//30, # shares {how many shares does the p2pool client keep}

REAL_CHAIN_LENGTH=24*60*60//30, # shares {how big is the N in PPLNS}

TARGET_LOOKBEHIND=200, # shares {not sure}
SPREAD=15, # blocks {don't know}

{I believe these are used to identify p2pool shares in the p2p network}
        IDENTIFIER='a41b2356a1b7d35e'.decode('hex'),
        PREFIX='5623b62178d2b8a3'.decode('hex'),
 
P2P_PORT=9323, {port other p2pool clients will connect to you on}

{bitcoin specific for min/max difficulty in units of target, google "bitcoin difficulty" for more info}
MIN_TARGET=0,
MAX_TARGET=2**256//2**32 - 1,

PERSIST=True, {tells p2pool to remember shares, connections, between sessions I believe}

WORKER_PORT=9322, {port miners connect to your p2pool node}

{the following is a list of IPs where you can download a sharechain and find lists of other clients the first time}

ANNOUNCE_CHANNEL='#p2pool-alt', {if you find a block, you announce it on IRC}

VERSION_CHECK=lambda v: True, {not 100% sure, either tells p2pool to check other p2pool nodes versions or your bitcoind version}

p2pool/networks.py
p2pool/bitcoin/networks.py

any other files else?

[airborne305]

i believe those are the only two files that need to be modified to fit whichever currency being added.

[walf_man]

I think so, but i was compared them, it's many files diff.
