Title: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on February 10, 2014, 02:26:20 AM Since it is so hard to find all the information in one location I thought I would start a thread detailing the changes necessary to make most POW altcoins work with p2pool. Thanks go out to all those who have posted this information elsewhere on the forum.
There are two files that will need to be changed: p2pool/bitcoin/networks.py p2pool/networks.py Will break these down in the next two posts. Over time I will update to reflect new information. Note: When a coin changes it's spec p2pool needs to be changed to match. Note: All nodes must run the same code. If there are any changes [some exceptions] it is recommended to start a new p2pool share chain by changing IDENTIFIER and PREFIX and deleting the p2pool/data folder. I maintain a GitHub that I keep updated of the coins I run on xpool.net (http://xpool.net) here: https://github.com/CartmanSPC/p2pool Here are some other popular repositories: https://github.com/narken/p2pool-altcoins https://github.com/Rav3nPL/p2pool-rav Please use caution when using some of these repositories as they may not have been updated to reflect changed coin specs.

This is where the coin specific settings are stored. All the information in this file needs to come from the source code of each coin and be updated if any of that information is changed. For reference here is the section of the code for litecoin: Code: litecoin=math.Object( litecoin=math.Object( Change litecoin to match the name of the altcoin. P2P_PREFIX='fbc0b6db'.decode('hex'), Replace 'fbc0b6db' with the values from main.cpp at pchMessageStart[4] = Remove all '0x' and combine the rest. P2P_PORT=9333, Replace 9333 by looking in protocol.h and finding the 2nd value after GetDefaultPort Some coins may have this in chainparams.cpp at nDefaultPort = ADDRESS_VERSION=48, Look in base58.h and find the value of PUBKEY_ADDRESS RPC_PORT=9332, Look in bitcoinrpc.cpp for GetArg("-rpcport", xxxx), xxxx is the RPC_PORT. Some coins may have this in chainparams.cpp at nRPCPort = RPC_CHECK= ... 'litecoinaddress' Look in bitcoinrpc.cpp after setaccount < If the altcoin has a 'space' between altcoin and address make sure you include the 'space'. You can also find this in rpcdump.cpp after dumpprivkey < SUBSIDY_FUNC=lambda height: 50*100000000 >> (height + 1)//840000, SUBSIDY_FUNC=lambda height: 'block reward' * 'satoshies' >> (height + 1)//'height where block halves'. For 'block reward' look in main.cpp for nSubsidy For 'height where block halves' look in main.cpp for nSubsidy -> nSubsidy >>= (nHeight / If a coin does not have a height where the block halves take out >> (height + 1)//'height where block halves' Comment Pay particular attention to verifying that you have this correct. Not doing so will result in some blocks being rewarded less than their full value. SUBSIDY_FUNC is only used in some instances. Quote Sometimes removed_fees contains None when P2Pool doesn't know the fee associated with a transaction, such as with old versions of *coind as a result of this old bug. Then, P2Pool has to make a conservative estimate of the subsidy using its computed base subsidy and the sum of the fees it does know. I have not seen a solution for coins with a random block reward. For random block reward coins some have suggested that the 'block reward' should be set to a low number as a high number would cause the block to be rejected [try to verify]. To do Determine the correct SUBSIDY_FUNC for coins that decrease by a percentage (WDC, Digibyte). Determine the correct SUBSIDY_FUNC for coins that have a random block reward ( ....more to come. For now here are my dirty notes: BLOCK_PERIOD= ------------------------------------------ target time between blocks <SECONDS> pulled from src/main.cpp (search for "static const int64 nTargetSpacing") ------------------------------------------ SANE_TARGET_RANGE = (2**256//1000000000 - 1, 2**256//1000 - 1) No changes for scrypt. DUMB_SCRYPT_DIFF = 2**16 No changes for scrypt. DUST_THRESHOLD = Note about DUST_TRESHOLD: In an effort to reduce the number of very small dust payments hanging around in peoples wallets, it does this by looking at your expected block payment and adjusted the required share difficulty until this is above its DUST_THRESHOLD value. 0.03e8 = 3000000 = 0.03 in satoshis [someone please verify] 1e8 = 100000000 = 0.00000001 in satoshis [someone please verify] 0.001e8 = 100000 = 0.001 in satoshis [someone please verify] Title: Re: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on February 10, 2014, 02:26:44 AM p2pool/networks.py
Unlike p2pool/bitcoin/networks.py some of the values here may be subjective and not clearly defined. I will add my own personal comments to each setting. Please feel free to add your own or discuss opposing viewpoints. For reference here is the section of the code for litecoin: Code: litecoin=math.Object( For now here are some of my notes (work in progress): SHARE_PERIOD SHARE_PERIOD sets a target time for how often to provide a share. It will regulating the difficulty to try to hit that target time taking into account the setting in TARGET_LOOKBEHIND. A lower number will have the effect of a lower share difficulty but also result in a larger share chain depending on the value in CHAIN_LENGTH. It may also cause additional orphans in the p2pool share chain as too low a difficulty will mean multiple miners will find shares at the same time. Not necessarily a bad thing as your all working on finding the same block but the winning finder will get the credit for the share. Comment I have seen people say a good rule of thumb is setting this to 1/5 of the altcoin block period. Too high a number will provide a higher diff share favoring higher hash rate miners. Too low a number increases resources (traffic, memory, storage) and orphans from competing miners finding the same shares. I believe setting this to 10 for most altcoins with block times of between 0.5 - 2 minutes is a good compromise. CHAIN_LENGTH CHAIN_LENGTH is the number of shares p2pool keeps before discarding them. It needs to be larger than or equal to REAL_CHAIN_LENGTH (it is normally equal to). One reason it increase this would be to show more data in the recent blocks found list. Example: 24*60*60//10 = 1 day of shares. 7*24*60*60//10 = 7 days of shares. [verification needed] REAL_CHAIN_LENGTH REAL_CHAIN_LENGTH sets the total number of previously found shares to include in the payout when a block is found. A longer chain provides a larger amount of time to find a share (get paid for work). It also contributes to how long you need mine to reach your "full" payout amount. Comment 24*60*60//10 is calculated as follows: (24*60*60)/10 = 8,640 shares are paid when a block is found. Take the value in SHARE_PERIOD and multiply by the number of shares to find how many seconds a share is valid for. For example: 8,640 shares will be paid with a share expected to be found every 10 seconds 8,640 * 10 = 86,400 seconds 86,400 / 60 = 1,440 minutes 1,440 / 60 = 24 hours 24 / 24 = 1 days I have tried various REAL_CHAIN_LENGTH settings but have settled on 24*60*60//10 for the following reasons: Allows a 24 hours period of time for finding of a share and for those shares to be valid based on having a share period of 10 seconds.
TARGET_LOOKBEHIND Determines the number of shares counted for difficulty regulation. Used to determine share difficulty based on the hash rate of p2pool (not individual nodes). Comment With large miners coming and going the difficulty adjustment takes too long with 200 shares on smaller p2pool networks. On larger p2pool networks this is not noticeable but I have resulted to setting this to 20 to accommodate large miners coming and going. SPREAD SPREAD determines how many blocks (max) to pay if a miner finds at lease one share. Does not go beyond the CHAIN_LENGTH/REAL_CHAIN_LENGTH setting. Comment 600/[block time]=x x*3=spread Quote bitcoin SPREAD=3 block every 600 seconds Baseline litecoin SPREAD=12 block every 150 seconds 600/150=4 4x3=12 bbqcoin SPREAD=30 block every 60 seconds 600/60=10 10x3=30 casinocoin SPREAD=60 block every 30 seconds 600/30=20 20x3=60 digitalcoin SPREAD=90 block every 20 seconds 600/20=30 30x3=90 (old spec) digitalcoin SPREAD=45 block every 40 seconds 600/40=15 15x3=45 (new spec) worldcoin SPREAD=120 block every 15 seconds 600/15=40 40x3=120 (old spec) worldcoin SPREAD=60 block every 30 seconds 600/30=20 20x3=60 (new spec) anoncoin SPREAD=10 block every 205 seconds 600/205=2.926829268292683 2.926829268292683x3=8.780487804878049 globalcoin SPREAD=45 block every 40 seconds 600/40=15 15x3=45 dogecoin SPREAD=30 block every 60 seconds 600/60=10 10x3=30 potcoin SPREAD=45 block every 40 seconds 600/40=15 15x3=45 craftcoin SPREAD=6 block every 300 seconds 600/300=2 2x3=6 (old spec) craftcoin SPREAD=30 block every 60 seconds 600/60=10 10x3=30 (new spec) nyancoin SPREAD=30 block every 60 seconds 600/60=10 10x3=30 It is not a hard limit # of blocks, it is the # times the average work required to solve a block. In other words, for a SPREAD=3 if the average time to block is 8 hours, then your shares will fall off the payout after 24 hours. So, if p2pool happens to get lucky and solve 10 blocks in that 24 hour period, your share will be paid for all 10 blocks. -------------------- To generate unique values for IDENTIFIER and PREFIX create a random string of 19 numbers and convert to Hex. I use the windows Programmer Calculator to do the conversion (View menu). Example: 5486237465184378845 = 4C2307E841C11FDD ....more to come!

You need to set it to False to bootstrap the sharechain, but once you've done that and have a bootstrap node up, set it to True It prevents anyone else from bootstrapping a sharechain Title: Re: P2Pool Detailed Settings for Altcoind Post by: pt78 on February 10, 2014, 09:12:32 PM Thanks for posting this ,I started working on adding our stuff and quickly realised there was more

To your own miner? /DIFF will control your share target to gets shares on the chain, +DIFF will control your pseudo share target to report work back even if it's lower than share target. Title: Re: P2Pool Detailed Settings for Altcoins Post by: ruggero on February 21, 2014, 02:16:39 AM Hi CartmanSPC,
first of all thanks for all the work you put in organizing this information about P2Pool. Reading it put me up with most of the knowledge I have of configuring new P2Pools for altcoins. I guess you read the disappointing answer of deeppurple72 on Github (if not go and check it https://github.com/forrestv/p2pool/issues/157#issuecomment-35691652). If you don't mind I'd like to help/contribute to the work you have started, and join forces to figure out how to make as many interesting cryptos as possible with p2pool. And then redistribute the code + the documentation for the good of the community as a whole. If you think it's too much work or you are not interested I will understand. But then I'll try to carry on on my own and of course give you all the credit you deserve! Ciao!

Like I said, I will share with the community soon. 2nd of all, your code was not rewritten, and not being "sold" 3rd because the new coins have low diff, 0 nodes/ 0 peers is actually an advantage 4th I would like to run the new pools for several months and then share with the community the knowledge.... I am not attempting to "sell" some custom modification of p2pool software, so let me make that perfectly clear! There is a forum on bitcointalk.org about "HOW TO MAKE ALT-COINS WORK WITH P2POOL" that has alot of good information. I just happened to discover on my own lots of additional information. When I said "bounty", it referred to information, and NOT p2pool software. Also, you will notice that I did NOT post any wallet addresses, as I did not seriously expect anyone to actually do that. Let me run some pools for a few months so I can make a little something first, then I will glady clue you people in.... Also, you guys were very hard on me when I requested some kind of way to penalize those cloud-miners, pools running into pools, "excessive hashrates" calling my request "ludicrous" and such.... and then you wonder why I suddenly don't feel so friendly? Hmmmm........ Title: Re: P2Pool Detailed Settings for Altcoins Post by: ruggero on February 21, 2014, 02:37:45 AM Please deeppurple72, let's keep this conversation on github. You made your point and I understand it and I accept it.
Of course you are welcome any time to join and contribute in documenting more in detail the internals of the P2Pool configuration. If not now in several months, or whenever it will not be an obstacle to your goals/plans. Title: Re: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on February 21, 2014, 06:59:32 PM Updated RPC_CHECK= ... 'litecoinaddress' to also include:

Title: Re: P2Pool Detailed Settings for Altcoins Post by: zvs on March 06, 2014, 09:25:41 AM What is MAX_TARGET? I've noticed it's different for various coins but not sure how it's computed. the maximum custom difficulty you can set hmm, nm, i'm not 100% sure about that actually, would have to look at the source again. i think that's what it is, though. btw, for any coin with, say, block times of 2 or 3 minutes or less, you should remove the following in data.py: if best is not None: best_share = self.items[best] punish, punish_reason = best_share.should_punish_reason(previous_block, bits, self, known_txs) if punish > 0: print 'Punishing share for %r! Jumping from %s to %s!' % (punish_reason, format_hash(best), format_hash(best_share.previous_hash)) best = best_share.previous_hash ... first off, these blocks are too fast to have that anyway. not to mention that the vast majority of the time this will be beneficial to your node. if you build off of that old valid *share that's just getting punished because of a new block, all the other clients will follow your chain (as it'll be the longest). this way you don't end up making a share some 3 seconds later and have some slow (or modified, heh heh) node build off the original share Title: Re: P2Pool Detailed Settings for Altcoins Post by: CDarvin81 on March 06, 2014, 08:17:31 PM Hi, i try and try but it don't work.

Title: Re: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on April 08, 2014, 12:43:32 AM What is MAX_TARGET? I've noticed it's different for various coins but not sure how it's computed. the maximum custom difficulty you can set hmm, nm, i'm not 100% sure about that actually, would have to look at the source again. i think that's what it is, though. btw, for any coin with, say, block times of 2 or 3 minutes or less, you should remove the following in data.py: if best is not None: best_share = self.items[best] punish, punish_reason = best_share.should_punish_reason(previous_block, bits, self, known_txs) if punish > 0: print 'Punishing share for %r! Jumping from %s to %s!' % (punish_reason, format_hash(best), format_hash(best_share.previous_hash)) best = best_share.previous_hash ... first off, these blocks are too fast to have that anyway. not to mention that the vast majority of the time this will be beneficial to your node. if you build off of that old valid *share that's just getting punished because of a new block, all the other clients will follow your chain (as it'll be the longest). this way you don't end up making a share some 3 seconds later and have some slow (or modified, heh heh) node build off the original share In ravs repo it does this with the following: Code: def should_punish_reason(self, previous_block, bits, tracker, known_txs): Same result? Title: Re: P2Pool Detailed Settings for Altcoins Post by: roy7 on April 08, 2014, 02:31:56 AM What's the purpose/advantage of removing the block punishing code? That's an area I've never looked at and am clueless about.

I was wondering is there anybody who can help out with karmacoin settings ? Chears Title: Re: P2Pool Detailed Settings for Altcoins Post by: Lucky Cris on August 18, 2014, 05:41:11 PM OP, just wanted to point out that some of these coins put the pchmeassagestart hex value in another file; so if it's not in the main.cpp it could be in another. I don't know if it has any significance, but figure I'd at least advise so you can update the OP
Title: Re: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on August 18, 2014, 09:14:05 PM Thanks Lucky Cris. Would you or anyone else happen to know what the other file is?
Title: Re: P2Pool Detailed Settings for Altcoins Post by: CarlClancy on August 18, 2014, 10:12:44 PM It shure would be nice to know where to look for them , i cant find them
Title: Re: P2Pool Detailed Settings for Altcoins Post by: Lucky Cris on August 18, 2014, 10:35:47 PM Thanks Lucky Cris. Would you or anyone else happen to know what the other file is? A couple of coins had it listed in the protocol.cpp file. But I was told they can technically be in any... I guess it depends on which coin is cloned? But it seems the Darkcoin clones uses prototocol.cpp. Title: Re: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on September 19, 2014, 06:46:59 PM Great explanation on P2Pools Pay Per Last N Shares (PPLNS) payout system from windpath:

i got trouble running a new fresh p2pool node. Got everything up and running and it seems its working... P2Pool nodes connect to each other.. stratum works everything seems fine.. Exept there p2pool nodes doesnt generate any shares.. I tried to bootstrap the shares with persist = False but it doesnt work. Also i got a lot of spam of: Code: Worker asdgasd submitted share with hash > target: Any idears how to properly bootstrap? Does the bootstrapping node may have to find a Block first? Any suggestions would be nice :) Title: Re: P2Pool Detailed Settings for Altcoins Post by: CartmanSPC on October 20, 2014, 06:02:50 PM A block should not need to be found. Which p2pool is this for?

Title: Re: P2Pool Detailed Settings for Altcoins Post by: scratchy on October 20, 2014, 09:22:11 PM i tried different ones.
for example this one: https://github.com/forrestv/p2pool I also tried to "bootstrap" on bitcoin testnetwork. (deleted all bootstrap addresses), launched with persist=false and changed identifiers but the sharechain just stays empty. i used p2pool_run.py --testnet Everything went fine, even with connected nodes, but i the share chain is still empty .. So overall: im unable to start the initial chain Title: Re: P2Pool Detailed Settings for Altcoins Post by: scratchy on October 21, 2014, 08:46:12 AM Tried also your fork:
