Title: Finding p2pool networks.py values for new altcoins
Post by: spoid on May 23, 2013, 09:06:31 PM
I have read all google and forum results I could find, it appears that nobody ever mentioned how to find a few certain values for the two networks.py files in p2pool:

SUBSIDY_FUNC
ADDRESS_VERSION
P2P_PREFIX

IDENTIFIER
PREFIX

I think I pretty much understand what all the other values do. However those 5 (and especially the hex values) make no sense to me. Do you strip them somewhere from the compiled source when a new coin has arrived?

Cheers!

SUBSIDY_FUNC can be found in the source code, specifically in main.cpp, search for nSubsidy, you'll find a line that looks a lot like

nSubsidy >>= (nHeight / 8400000);

The C++ syntax is different than the python syntax, but that is where you can get the information.

For ADDRESS_VERSION, look again in the sourcecode in the file base58.h, and find the value of PUBKEY_ADDRESS.

For the other 3 values, I'm under the impression that they are not values inherent to the alt-coin, but rather values to allow various p2pool nodes for a given alt-coin to communicate with each other.  Therefore, there is no way to "look them up" in the coin itself -- you have to coordinate the values between the p2pool nodes that you want to intermesh with.

thanks a lot! so if a coin was just created and I am running a solo node (remove BOOTSTRAP_ADDRS and PERSIST=False) anyways, can I just leave in the old hex values of another coin for the time being or do I have to create new values given after a certain rule?

My experience, at least when running a "private" p2pool has been that leaving the old hex values from another coin will work in the sense that p2pool will work with the new coin.  I don't know one way or the other whether it leaves open the possibility for misbehavior or crosstalk if you have a port open where p2pools for the "other" coin find yours and mistakenly think they can talk to it.

Incidentally, what does the PERSIST flag do?   I only started tinkering with p2pool configuration about a week ago myself.

I don't really know as well, just took it from a post by blastbob:

Quote
In p2pool / p2pool / networks.py:

change the
BOOTSTRAP_ADDRS='188.120.239.144 81.200.245.198 85.234.62.99 81.200.241.54 217.77.220.40'.split(' '),
to
BOOTSTRAP_ADDRS=''.split(' '),

Change PERSIST=True, to PERSIST=False,

Change P2P_PORT=9777, to something else

In p2pool / p2pool / bitcoin / networks.py

Change ADDRESS_VERSION=8, to ADDRESS_VERSION=25


Removing info in addrs and Persist=False will make your node run solo. Can be a good idea until parameter is 100%
No guarantee the above is 100% correct
Rest you need help from others

Hey man, I am doing the same research for a couple of days.

Can you tell me, how to find out, how to change those values in networks.py?

SHARE_PERIOD
CHAIN_LENGTH
SPREAD

Post by: schnebi on May 24, 2013, 09:13:35 AM
I think now i got it this far...

But the Problem ist: The RPC connection of P2Pool to bitcoind is working. But then it says testing P2P connection, and nothing happens... I set Port '3234' in the 'networks.py' '/bitcoin/networks.py' and in the .conf file for the coin to the same value.

Maybe it has somethig to do with the 'P2P_PREFIX' in the 'bitcoin/networks.py'???

In most working p2pool sources I downloaded the "p2pool port" was different in the bitcoin/networks.py and the networks.py - I think one is for communication between different p2pools and one is the "port=" from your .conf file ...

I tried to modify my files for a solo p2pool from feathercoin to phenixcoin but am only getting:
"Check failed! Make sure that you're connected to the right bitcoind with --bitcoind-rpc-port!"

@schnebi
I did not really found out how they work exactly, but I think that
SHARE_PERIOD
CHAIN_LENGTH
don't have to be changed or only fine-tuned later since they deal with the p2pool's share system.

as for SPREAD, i read somewhere that you should adapt it to the block target time (i.e. bitcoin has SPREAD=3 and creates a block every 10 minutes, litecoin has SPREAD=12 and creates a block every 2.5 minutes, I saw BQC with SPREAD=30 and it creates a block every 1 minute I think). However there seem to be exceptions, I have no idea why I am seeing feathercoin pools with SPREAD=120.

I see that you are ready to release a Luckycoin Pool on release, so I assume you got it to work?

I thouht i would be ready, to make a LuckyCoin Pool, but i think there are still some small issues. I tried setting up al Goldcoin-P2Pool for practicing purpose and everything seems fine so far. The Pool is running, and the workers can connect. But the workers can't submit shares to the Pool. SO the Hashrate stays at 0,0 KHashs......

Here are my 'networks.py' and '/bitcoin/networks.py'.... Maybe you can see my mistake

You can try to connect your Workers at crypto-coins.de:8909

Everythings seems finde... But no submitted shares...  >:(

hmm, so maybe those share values are important after all. did you mindless try all values from other copycoins for

SHARE_PERIOD=90, # seconds
CHAIN_LENGTH=24*60*60//10, # shares
REAL_CHAIN_LENGTH=24*60*60//10, # shares
TARGET_LOOKBEHIND=200, # shares

?

Also, which p2pool version did you originally set out with? Did you change everything to "gldcoin" ONLY in the networks.py files? I thought that would give some problems further down the code - f.e. "'gldcoinaddress' in (yield bitcoind.rpc_help()) and" shouldn't work without you changing that method name as well?

I tried several combinations of the values. But it made no difference.... But i haven't tried all posible combinations yet.

I don't really know what you mean by 'Changing the methods' name.... In fact, the P2Pool server does recognize the workers, and also the standart Payout address, where to pay the fee... It also submits the Blocks to the Worker... The Worker is just not able to submit shares to the Server... It just says "New Block detected" and "server requestet work restart"

Found  

Code:
return (GetTime() - nLastUpdate < 10 &&
            pindexBest->GetBlockTime() < GetTime() - 24 * 60 * 60);

in main.cpp of Goldcoin....

So i think CHAIN_LENGTH=24*60*60//10 is right


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: schnebi on May 24, 2013, 11:29:08 AM
I have another idea... It seems like the difficulty of the work P2Pool sends to the worker is to high. Its 0.99999

At my other P2Pools the Share difficulty is someting like 0.01....

So its simply to difficult for my Worker to get accepted share.

Does that sound reasonable? And how can I change?


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: spoid on May 24, 2013, 11:39:34 AM
maybe try to lower SHARE_PERIOD=90, # seconds to 30?


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: schnebi on May 24, 2013, 11:52:19 AM
Okay... I think i got it in theory....

There is a line saying DUMB_SCRYPT_DIFFICULTY which say 2**16 or 2**12 for all Altcoins.

I changed the value to "1" as it is for Bitcoin and i got hundreds of accepted shares per minute... But thats also incorrect.... So I Think we have to play with this value... I wonder, why it works with all other Coins with a value of 2**16 or 2**12


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: schnebi on May 24, 2013, 12:20:06 PM
I'm pretty shure now, the Problem is all about the difficulty...

I modified a new networks.py again the same way i did it before, because i thougt, that somewhere i made a mistake. And now the behaviour is changing. Im getting Pretty much accepted shares, but all Shares are with a Difficulty of "0"...... I will make screenshots later that day, so maybe it will become clearer whts the Problem...

However when skimming through those I found those were the same for all scrypt coins and all sha256 coins. So I only saw 2 different versions. I still don't get the RPC connection to work though. :(

Hmm.  If I understood correctly the config files you quoted in post #17 are your attempt at modifying the feathercoin settings to get p2pool to work with phenixcoin, but you are getting an RPC connection error when you actually run p2pool after launching phenixcoin?

Two possibilities come to mind.  First, the RPC_PORT value should ordinarily be set in the bnetworks.py file to the phenixcoin peer-to-peer listening port.  My understanding (I haven't doublechecked) is that the default P2P port in phenixcoin is 9555.  Unless you've changed this port (with a port=9666 line) in your phenixcoin.conf file, you should set RPC_PORT=9555 in the bnetworks.py file.

Second, you may need to change 'feathercoinaddress' to 'phenixcoinaddress' in the RPC_CHECK entry in the bnetworks.py file...I think this may be a coin-specific call to obtain a coin address.

Hope this helps, or at least, moves you on to troubleshooting a different error code.   ;)

I thought i got it running. I modifed the networks.py and i was able to create a pool for Goldcoin.... Now i tried to do the same for DragonCoin..... But Iam stuck at the point, where P2Pool says "Testing bitcoind P2P connection to 127.0.0.1:12579"

I don't understand, why it is not going on, because i unsed exactly the same settings than for Goldcoin. Just changed the Port for one Number....

yeah, that's exactly where it ends for me as well. Nice catch on the "DragonCoin address". How did you guess that there was a space there? I gave up on it at that point - dragoncoinaddress, dncaddress, DragonCoinaddress, DragonCoinAddress, smallchangeaddress... nothing seemed to work.

I wonder if those nodes are really running solo anyway. Since my phenixcoin pool is still somehow connected to the feathercoin p2p network and shows some pool data. When I connect my miners to my phenixcoin pool, they connect and mine just fine, but if I do a ./phenixcoin gethashespersec on the VPS it returns 0. So it is definitely not solo mining with my wallet ...? :(

I wonder if those nodes are really running solo anyway. Since my phenixcoin pool is still somehow connected to the feathercoin p2p network and shows some pool data. When I connect my miners to my phenixcoin pool, they connect and mine just fine, but if I do a ./phenixcoin gethashespersec on the VPS it returns 0. So it is definitely not solo mining with my wallet ...? :(

Yeah.. that was a little bit tricky... I searched all the Source files of Litecoin for the Term "litecoinadress". And then i looked up the same File in DragonCoin and found the term "DragonCoin address"

I' also tried to do a luckycoin pool. The P2Pool is starting completely with this coin. But then it just sends Work with the difficulty "0" to the worker, so that the accepted shares are worth nothing.....

Maybee someone can have a look at that:

This are my networks.py:

Code:
dnccoin=math.Object(
        PARENT=networks.nets['dnccoin'],
        SHARE_PERIOD=60,
        CHAIN_LENGTH=24*60*60//10,

        P2P_PORT=48909,
        MIN_TARGET=0,

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

Code:
dnccoin=math.Object(
        P2P_PREFIX='fbc0b6db'.decode('hex'),
        P2P_PORT=48909,
        ADDRESS_VERSION=62,
        RPC_PORT=9996,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'DragonCoin address' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: 95*10000000 >> (height + 1)//10519200,
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        BLOCK_PERIOD=60, # s targetspacing
        SYMBOL='DNC',
        CONF_FILE_FUNC=lambda: os.path.join(os.path.join(os.environ['APPDATA'], 'dragoncoin') if platform.system() == 'Windows' else os.path.expanduser('~/Library/Application Support/dragoncoin/') if platform.system() == 'Darwin' else os.path.expanduser('~/.dragoncoin'), 'dragoncoin.conf'),

        DUMB_SCRYPT_DIFF=2**16,
    ),

This is my DragonCoin.conf

Code:
rpcuser=******
rpcpassword=*******
rpcallowip=*.*.*.*
rpcport=9996
port=12579
addnode=198.46.137.53
addnode=198.12.67.152
daemon=1
server=1

And this is what happens:

http://www.crypto-coins.de/html/unbenannt.jpg

After that it's stuck at this screen... I really don't know, what to change....

In bitcoin/networks.py, set:
P2P_PORT=12579
RPC_PORT=9996

Post by: Kyune on May 28, 2013, 09:49:41 PM
I think I may have figured this out.  I had been bumping into the same problem (stalling at the P2P connection) on some coins but not others.  I finally realized I was wrong in an initial assumption...the P2P_PREFIX setting in bitcoin/networks.py is in fact a coin-specific setting -- which is logical, as the other settings in that file are coin-specific as well.   In fact, it looks like it is basically the "magic value" or "magic number" referred to in https://en.bitcoin.it/wiki/Protocol_specification, and after poking around in the code I think you can find it in main.cpp at pchMessageStart[4]=...  Using this specific value as the P2P_PREFIX fixed the problem for me.

So, for example, I haven't ever installed Dragoncoin myself, but looking quickly at the relevant line in main.cpp:

Code:
unsigned char pchMessageStart[4] = { 0xfc, 0xd9, 0xb7, 0xdd };

Thus, for Dragoncoin, try setting

Code:
P2P_PREFIX='fcd9b7dd'.decode('hex'),

and let us know if that gets you past stalling at the P2P connection.

Hope this is helpful.

Any insight into why block numbers would display inaccurately?

I just set up a pool for AmericanCoin and I think I got all the settings correct but block numbers being shown for recent blocks are not accurate

With this one its regarding something to do with Bitbar?? possible it was around the area you edited in the main.py.

From what i have searched and tinkered with so far the only 3 files we need to touch are networks.py in p2pool folder and networks.py and helper.py in bitcoin folder.

napoleon maybe re-do your settings but dont edit the main.py just the 3 files i mentioned.

ok will make again the py's again and we talk in a few hours. can you tell the lines in help.py ? if that is possible ? not to read the hole code ?

Code:
SUBSIDY_FUNC=lambda height: 95*10000000 >> (height + 1)//10519200,

i also found that 95 are the coins
100000000  no idea what is this
>>(height + 1) again no idea
//10519200 is the number from main.cpp in nSubsidy

according to your error its not in your help.py but your main.py

File "/root/p2pool/p2pool/main.py", line 446, in run
    net = networks.nets[net_name]

ok will make again the py's again and we talk in a few hours. can you tell the lines in help.py ? if that is possible ? not to read the hole code ?

Code:
SUBSIDY_FUNC=lambda height: 95*10000000 >> (height + 1)//10519200,

i also found that 95 are the coins
100000000  no idea what is this
>>(height + 1) again no idea
//10519200 is the number from main.cpp in nSubsidy

You got the same idea as me  ;D
As i understand this method:
95 = Block reward
10000000 =  ???
>> (height + 1) = this returns the current block chain length
10519200 = either was total coins or when to half rewards i can not remember

Some tips below for you as well  :D

When redoing your p2pool your only need to edit:
Code:
p2pool-main-folder\p2pool\networks.py - P2PNTWK
p2pool-main-folder\p2pool\bitcoin\networks.py - BCDNTWK
p2pool-main-folder\p2pool\bitcoin\helper.py - BCDHLP
networks.py for your coin seam to be sorted, just make sure your P2PNTWK ports are not the same as your BCDNTWK. BCDNTWK ports should be the ones used in your coin.conf.

the specific line in BCDHLP you need to edit is: (it could contain more coin names
Code:
if 'litecoin' in net.NAME or 'feathercoin' in net.NAME:

Change it to:
Code:
if 'litecoin' in net.NAME or 'feathercoin' in net.NAME or 'CoinName' in net.NAME:

Please note the coin name you put in here must also be what you use to call your coin in P2PNTWK.

This is found in P2PNTWK under "CoinName=math.Object("
Code:
PARENT=networks.nets['CoinName']

I hope that wasn't just a bunch of gibberish  ;D
I'll try do a more explained version later if you would like as I'll be heading off to work soon.

i also found something about p2poolprefix. but i don't know how to chenge it to hex code the prefix is at

src\main.cpp  and it looks like this
 
Code:
pchMessageStart[0] = 0xfc;
Line 1993:         pchMessageStart[1] = 0xc1;
Line 1994:         pchMessageStart[2] = 0xb7;
Line 1995:         pchMessageStart[3] = 0xdc;

also this is "10519200" to half rewards. as i know

and may i ask something off topic that i hav problem and i can't find an obvius answer....I am trying to compile let's say worldcoin for example.. make -f makefile.unix USE_UPNP=- and i get this error on the code...

Code:

make: *** [obj/main.o] Error 1

if you know anything plz pm me. not to mess with the posts on this..  ;D

In regards to the p2poolprefix, are you talking about:

From BCDNTWK
Code:
P2P_PREFIX='fbc0b6db'.decode('hex'),
or
From P2PNTWK
Code:
PREFIX='b6c0601991aa19a2'.decode('hex'),

the BCDNTWK P2P_PREFIX can be found in the main.cpp at about line 2384 just search for "unsigned char pchMessageStart" it will contain some numbers and letters heres an example from MemeCoin:
Code:
unsigned char pchMessageStart[4] = { 0xfb, 0xc0, 0xb6, 0xdb }; // MemeCoin: increase each by adding 2 to bitcoin's value.

you would take
Code:
0xfb, 0xc0, 0xb6, 0xdb
and change it to
Code:
fbc0b6db
this is for the BCDNTWK py.

For the other prefix from P2PNTWK, this is used (as i understand) to connect the p2pools with other p2pools, same with the identifier.
I am unsure about this setting, still looking around.

The prefix you found in main.cpp i am unsure what it is used for or if it is used at all.
Code:
pchMessageStart[0] = 0xfc;
Line 1993:         pchMessageStart[1] = 0xc1;
Line 1994:         pchMessageStart[2] = 0xb7;
Line 1995:         pchMessageStart[3] = 0xdc;

it does look similar to what i had or even could be the same thing.

ok this is my new code... i havent tested it yet... i am just sending you to take a look.... as i see at this pool https://github.com/hakabane/p2pool-altcoins/blob/master/p2pool/networks.py (it has many p2pools) he guy there it doen't changed many things... so i made the codes look like digitalcoi. and with no testnet on it ... (i think that it may couse some problems)

take a look at the code.

Code:
nets = dict(
    worldcoin=math.Object(
        P2P_PREFIX='fbc0b6db'.decode('hex'),
        P2P_PORT=11081,
        ADDRESS_VERSION=73,
        RPC_PORT=11082,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'worldcoinadress' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: 1*10000000 >> (height + 1)//1080000,
        BLOCKHASH_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        BLOCK_PERIOD=30, # s
        SYMBOL='WDC',
        CONF_FILE_FUNC=lambda: os.path.join(os.path.join(os.environ['APPDATA'], 'worldcoin') if platform.system() == 'Windows' else os.path.expanduser('~/Library/Application Support/worldcoin/') if platform.system() == 'Darwin' else os.path.expanduser('~/.worldcoin'), 'worldcoin.conf'),
        BLOCK_EXPLORER_URL_PREFIX='',
        ADDRESS_EXPLORER_URL_PREFIX='',
        SANE_TARGET_RANGE=(2**256//100000000 - 1, 2**256//1000 - 1),
        DUMB_SCRYPT_DIFF=2**16,

also the other one

Code:
worldcoin=math.Object(
        PARENT=networks.nets['worldcoin'],
        SHARE_PERIOD=30, # seconds
        CHAIN_LENGTH=24*60*60//10, # shares
        REAL_CHAIN_LENGTH=24*60*60//10, # shares
        TARGET_LOOKBEHIND=200, # shares
        SPREAD=72, # blocks
        IDENTIFIER='f982abe394923510'.decode('hex'),
        PREFIX='8208c1a53ef649b0'.decode('hex'),
        P2P_PORT=25358,
        MIN_TARGET=0,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=True,
        WORKER_PORT=25359,
        BOOTSTRAP_ADDRS=''.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-alt',
        VERSION_CHECK=lambda v: v : True,
    ),

check the files at ghub.. you will see not many changes just the basic one

looks all good, don't forget to add worldcoin to helper.py in the bitcoind folder,

Also i forgot to add, in your P2PNTWK file change
Code:
PERSIST=True,
to
Code:
PERSIST=False,

And its gotta be capital "F",
This value tells the p2pool if it should mine solo or connect to other p2pools.

Fire it up and let us know,
In regards to your compile error i don't have a Linux box so can not help you there sorry  :(

ok making the pool right now... wish me luck guys lol

ok it doesn't open the screen command.. here is it.

Code:
screen -d -m -S wdcpool ~/p2pool/run_p2pool.py --net worldcoin -a Wd7Jrk6Yeaq8Ztn1umQuv2sM2mRzgyo3Ut -f 2 --give-author 0 --w 19327 --bitcoind-p2p-port 11081 --bitcoind-rpc-port 11082 walletusername walletpassword

anyideas ?

also when i pull the run_p2pool.py help i get these errors

Code:

worldcoin SPREAD=120 block every 15 seconds      600/15=40       40x3=120

sa i found out in one post here and there.


anyone found anything for HYC?

The main difference in HYC is a blank in 'hypercoin address':

p2pool/bitcoin/networks.py
Code:
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'hypercoin address' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),

Also must be change the P2P_PREFIX:
Code:
        P2P_PREFIX='fcd9b7dd'.decode('hex'),

ok how did you found this couse i was trying to find this for days.

also what about nSubsidy. at the code it should be like nSubsidy >>= (nHeight number.) but in this coin it has 25*coins and something under it. alll the rest are the sane. somehow

It seems that subsidy never halves (until reach max money), then:
Code:
        SUBSIDY_FUNC=lambda height: 25*10000000,

You can find the 'xcoinaddress' string in src/rpcdump.cpp, searching 'dumpprivkey <'

hi again guys.

i hav made a pool for WDC it's working perfecty for some days now. but still i hav a small problem. i get like 10% DOA and i am really pissed off by that.

this is the code i hav. i need to change anything couse i think i hav made a mistake somewhere

I posted those settings from research but do not know if my assumptions are correct.

I use them for my pools and they seem to work correctly but it's hard to say what would happen if a bunch of other p2pools decided to connect. Brought up some other p2pools to simulate other pools connecting but without a lot of hash rate at the other nodes my results were promising but inconclusive.

the ports are correct. any ideas ?

I imagine you are trying to do a pool for HyperCoin? The devs messed up on the ports being used. To make matters worse the original post for the announcement had the wrong ports as well. In that thread I pointed it out. They graciously gave me a donation :)

Look up the announcement thread for the port information. I forget off the top of my head but it is there. The default ports were something like 5 digits for one and 4 for the other.

For future reference, you can find the P2P_PORT in the coin's source code in the protocol.h file, it's the 2nd value after GetDefaultPort.

You can find RPC_PORT in the source code in the bitcoinrpc.cpp file, look for GetArg (-rpcport, xxxx), where xxxx is the port.

I'm talking about the values you would specify in the bnetworks.py file.

Just to confirm what I *think* I know....

These values can be specified in the *.conf file as well can't they?  (To match bnetwrks.py)

no idea... i found the problem with that .... it wants that in linux .conf file

ipcallowip=127.0.0.1
not
rpcconnect=127.0.0.1

now i am getting a huge nubmer or errors that i can't find... i make everything like i do to most coin pools. that means:

i find the address for PUBLIC ADDRESS from base58.h
i find height or something like that from  nSubsidy >>= (nHeight / 8400000); from main.cpp
i change the port and rpc port at networks.py
i change the worker port and the other port that connect the pools.
i delete the IDENTIFY AND PREFIX i leave them like that (don't couse me any problems for solo pools)
Code:
IDENTIFIER=''.decode('hex'),
        PREFIX=''.decode('hex'),

i change the helper.py with or 'netowrkname' like this

Code:
if 'lite' in net.NAME or 'feather' in net.NAME or 'chn' in net.NAME or 'franko' in net.NAME or 'digital' in net.NAME or 'worldcoin' in net.NAME:

what else. and i run with python. (i create the screen first)

but then let's say for fastcoin i get like 2 pages errors .....

i also hav no idea what this is

Code:
CHAIN_LENGTH=24*60*60//10, # shares
REAL_CHAIN_LENGTH=24*60*60//10, # shares
SHARE_PERIOD=10, # seconds

and on the other networks.py this one and how i can translate it

Code:
P2P_PREFIX='f9beb4d9'.decode('hex'),

and on the other networks.py this one and how i can translate it

Code:
P2P_PREFIX='f9beb4d9'.decode('hex'),



The P2P_PREFIX was explained by Kyune here:



I think I may have figured this out.  I had been bumping into the same problem (stalling at the P2P connection) on some coins but not others.  I finally realized I was wrong in an initial assumption...the P2P_PREFIX setting in bitcoin/networks.py is in fact a coin-specific setting -- which is logical, as the other settings in that file are coin-specific as well.   In fact, it looks like it is basically the "magic value" or "magic number" referred to in https://en.bitcoin.it/wiki/Protocol_specification, and after poking around in the code I think you can find it in main.cpp at pchMessageStart[4]=...  Using this specific value as the P2P_PREFIX fixed the problem for me.

So, for example, I haven't ever installed Dragoncoin myself, but looking quickly at the relevant line in main.cpp:

Code:
unsigned char pchMessageStart[4] = { 0xfc, 0xd9, 0xb7, 0xdd };

Thus, for Dragoncoin, try setting

Code:
P2P_PREFIX='fcd9b7dd'.decode('hex'),

and let us know if that gets you past stalling at the P2P connection.

Hope this is helpful.


I can't really help with the chain length as it is confusing to me too.

That is my understanding, yes.  The above just lets you find the defaults if the coin dev doesn't accurately document the default ports, which does happen.

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

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..

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

any ideas ?



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'),


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)

Post by: minerapia on August 21, 2013, 10:09:07 AM
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))


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: guugll on August 21, 2013, 10:49:42 AM
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...

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.


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: guugll on September 05, 2013, 09:26:10 PM
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?

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.

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?

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:

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

you probably need another source for PoW and PoS coin.
better look for NVC, BTB p2pool source

Hey man I think you got confused with netcoin.io, that's not it. The netcoin.pw I am talking about is this one https://cryptocointalk.com/topic/1132-netcoin-net-launched-today/ its scrypt based on litecoin ;)

It is confusing I know.

ok 2 times Netcoin - sorry i was not aware.
then should work with that source but how you wanna payout the superblocks?

- 1024 coins per block, and a random super block each hour that has 8X the normal payout (8096 coins)

Do you think this superblock is whats breaking the web interface and trowing the errors? Honestly I have no idea how to deal with it, I thought the pool would just split whatever the miners find and keep going. I personally don't like this superblock thing and if it was up to me it would be gone by now...thanks for helping man!!

i tryed to make just PoS+PoW p2pool modification from NVC/BTB source and i was not successfull - but i did not tryed yet the last advice from minerapia. (my test env. is down now and i do not have much time)
the p2pool code modifications for PoS are written in this thread but in case of any special stuff in coin you need to modify the p2pool code.
for NVC the dev. of the coin modified the coin to be able to run with p2pool and BTB is very similar coin to NVC

so you need basically very good python skills and good contact with the coin dev. in order to be able to understand the special features and python skill to make it work with p2pool.
and in case of "random" superblocks i do not see any way how to work with the 8times higher value for that coin - you need to ask the dev how you would find out that you are mining or have mined the superblock and in that case use different payout method for the miners and then again go on standard.

well maybe try first some normal PoS coin p2pool modification and then build on that knowledge - that will be my way after i will have more time... but still i will test the last advice from minerapia because i spent a lot of time on that and i am curious if it will work.

good luck man - i like the p2pool idea because i feel all that coins who are having p2pool are the most successfull coins. But only one dev. made coin and p2pool source modification at the beginning - no one else is doing it beucause they waste time on special features of the coin and then there is no power to make the p2pool working with it.

Post by: triggermage on November 06, 2013, 08:46:30 PM
Thanks man I wish you good lucky too!

I agree with you, non standard code in the coin code only makes things harder, I will keep trying till I get the pool up!! Thanks again!

if "randomly" superblocks would be possible (which retard introduced this? sheesh...), you could abuse this system to only create superblocks lol

Post by: yahma on December 24, 2013, 06:18:25 AM
There seems to be some confusion about the values for networks.py, so lets see if we can sort things out and provide a bit of clarification:

SHARE_PERIOD: How often should P2Pool generate a new share (rule of thumb: 1/5 - 1/10 of the block period)
CHAIN_LENGTH: How many shares P2Pool client keeps
REAL_CHAIN_LENGTH: The {N} value in PPLNS
Note:  REAL_CHAIN_LENGTH must always be <= CHAIN_LENGTH

SPREAD:  How long a 'share' is valid (ie. for how many block can be paid for this share)
TARGET_LOOKBEHIND: Is used for diff calculations.  (ie. how many previous shares to use in calculating difficulty) - lower values can be used to prevent a big miner from getting too many shares before diff rises
PERSIST: False (if you want to allow your server to run independently of any bootstrap nodes... but still allow syncing if they exist).  True will require other nodes on the network to run.
IDENTIFIER & PREFIX: P2Pool will only sync with other nodes who have Identifier and Prefix matching yours (and using same p2p port).. if any of the above values change, a new identifier & prefix need to be created in order to prevent problems.

Example:

Code:
     casinocoin=math.Object(
        PARENT=networks.nets['casinocoin'],
        SHARE_PERIOD=5, # seconds target spacing
        CHAIN_LENGTH=3*60*60//5, # shares
        REAL_CHAIN_LENGTH=3*60*60//5, # shares
        TARGET_LOOKBEHIND=60,
        SPREAD=60, # blocks
        IDENTIFIER='7696C5EF0B281C2F'.decode('hex'),
        PREFIX='4C2E2CD651764B9F'.decode('hex'),
        P2P_PORT=23640,
        MIN_TARGET=0,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=False,
        WORKER_PORT=8840,
        BOOTSTRAP_ADDRS='csc.xpool.net bigiron.homelinux.com'.split(' '),
        ANNOUNCE_CHANNEL='#p2pool-alt',
        VERSION_CHECK=lambda v: True,
    ),

CasinoCoin generates a new block every 30 seconds.  SHARE_PERIOD should be 1/5 to 1/10th of that.  In this case 5s is (1/6) share period.  Having a value above 1/5 risks more stale shares & larger inefficiency.
CHAIN_LENGTH & REAL_CHAIN_LENGTH are set up to allow for 3 Hour PPLNS.
TARGET_LOOKBEHIND is set to 60 (shares) giving a 300 second (5min) difficulty adjustment.
SPREAD is set to 60 blocks, so a share will be valid up to 60 blocks or REAL_CHAIN_LENGTH (3 hours), whichever is shorter.
P2P_PORT, IDENTIFIER & PREFIX must match the other nodes you wish to sync with... (all the above values must also match)

Hope this clears a few things up!!

Hi guys!

Thanks for really helpful information.
But I still can't understand or I miss something:

- How to calculate IDENTIFIER & PREFIX value adding new coin in p2pool ?

Also inside file bitcoin/helper.py I do not see that line

Quote
if 'lite' in net.NAME or 'feather' in net.NAME or 'chn' in net.NAME or 'franko' in net.NAME or 'digital' in net.NAME or 'worldcoin' in net.NAME:

Where is it? Or there already no needs to add new coin description?

Thanks!

Merry XMas and Happy New Year to all :)

So I've been trying to get a few alt coin pools up lately. I've been working on lottocoin, grandcoin, earthcoin and luckycoin. None of which have i seen very much success. I'm fairly confident that through this topic, I've been able to add the correct information in the networks.py files. I can post copies of those if needed. However, what I'm really having issues with is this message that is being logged in the output of p2pool each second.

This error is logged several times a second and is happening for each one of the new coins I've tried. However, the same p2pool code is running WDC, CSC and FTC pools successfully without that error.

Also, I'm able to successfully connect to the pool and hash in it, but it seems the connection to the wallet daemon is lost every few minutes and takes a minute or two to reconnect. My miner will show that it's having issues connecting to the stratum server and then eventually connect back up and start hashing again.

Does anyone know the cause of this error? Is it just something code related to these new coins? I'd like to continue making p2pools for these new coins, but it seems the hurdle of adapting the p2pool code for these might just be too big to overcome.

Same here but I have another error :)
I always have an error "Authorisation required" after running pool
Quote
run_p2pool.py bituser bitpassw --net lottocoin
I have feeling its because of incorrect IDENTIFIER and  PREFIX values.
How did you calculate them?

btw, did you found line where to add new coin name in bitcoin/helper.py (about what talking here at the top of topic ? Something like that:

The IDENTIFIER and PREFIX in the network.py are only used to identify your p2pool node with others of the same coin. Technically, if you want to run a p2pool node with others, these values must be the same across all nodes. If you don't want to run the p2pool with others, then you can create these yourself and keep them private so no nodes can connect with you.

However, if you're referring to the P2P_PREFIX in the bitcoin/networks.py, then yes, that is coin specific. I believe that is mentioned earlier in this thread on where to find it, so read up a little, but I know you'll be looking in the coins source in the main.cpp file. Lool for pchMessageStart[4] and you'll see the hex codes that you need to pull out there.

As far as the helper.py file, I don't think that needs to be modified anymore. At least I haven't been modifying it and have been able to successfully create some pools. I don't think the line that is referenced above exists anymore.

Thank you, very useful. Yes about P2P_PREFIX  I got it and found how to create it.

Ok, let's say I want to run p2pool node with others. But for some new coin, that still do not have much nodes, how to generate IDENTIFIER and PREFIX ?
If I writing random string, its not working, pool return me exception.

Can I take ready values from some other coin? And will it conflict with existing coins inside networks.py?
Let's say I have FST and want to add LOTOCoin. Should that values (IDENTIFIER ) to be unique for each coin listed in networks.py or unique values per coin doesn't required?

Let's say I have FST and want to add LOTOCoin. Should that values (IDENTIFIER ) to be unique for each coin listed in networks.py or unique values per coin doesn't required?


I have always just slightly modified them from another coin already in network.py. Yes, it has to be unique within network.py or I think you'll get an error. So for example, if the litecoin IDENTIFIER is
Code:
IDENTIFIER='e037d5b8c6923410'.decode('hex')
, then just take that and slightly modify a few numbers. Make it something like
Code:
IDENTIFIER='e037d5b8c6923415'.decode('hex')
and see if that works (just changed the last digit). I'm pretty sure that will be fine, as it's what I've done, but if there is someone else who thinks I'm off, please speak up.


However, if you want other to be able to connect to you, it will need to be unique and posted online so others can follow. If you want to fork the original p2pool code or forkl Rav3n or Cartman's code in github and add your own entries, then report back if you're successful, then others will know and be able to obtain your values and run their own nodes for your coin. That's how most of the entries in network.py get shares, through github forks.

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

Cartman, thank you looks like I almost done with config settings :)
But now... I trying to run your version of p2pool, for craftcoin.
Craftcoin without pool for solo working good.

When I do
Quote
run_p2pool.py bituser bitpwd --net craftcoin

I getting error "twisted.web.error.Error: 401 Authorization Required"
 

And funny thing - with NameCoin error too:
Quote
run_p2pool.py --net namecoin namecoinuser namecoinpwd
>Testing bitcoind RPC connection to 'http://127.0.0.1:8336/
>Check failed! Make sure that you're connected to the right bitcoind with --bitcoind-rpc-port!
Maybe someonehad same error  and  have an idea?

Thanks!
Found several things:
RPC_PORT in the bitcoinrpc.cpp - but updated wallets have only constants DEF_RPC_PORT etc there, real values can be found in the protocol.h file.
Also there values for testnet:
DEF_PORT
const int DEF_RPCPORT
const int DEF_TESTNET_PORT
const int DEF_TESTNET_RPCPORT

All testnet and other ports are correct now, but still same error "Check failed".
That strange, some coins working good with p2pool, some have that error.

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.

Code:

2013-12-30 00:24:16.669050 > p2pool.util.pack.LateEnd:

Now, what I noticed is in the pack.py file, the functions
Code:
def _unpack(self, data, ignore_trailing=False):
        obj, (data2, pos) = self.read((data, 0))

        assert data2 is data

        if pos != len(data) and not ignore_trailing:
            raise LateEnd()

        return obj

 def unpack(self, data, ignore_trailing=False):
        obj = self._unpack(data, ignore_trailing)

        if p2pool.DEBUG:
            packed = self._pack(obj)
            good = data.startswith(packed) if ignore_trailing else data == packed
            if not good:
                raise AssertionError()

        return obj
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.

    ),

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 (https://github.com/forrestv/p2pool/issues/151) on the official p2pool github in case anyone wants to contribute.

Guys. Is anyone interested in opening a Skype Chat group to discuss P2Pool configurations.

I have setup several coins that are working perfectly now on P2Pool.

These include Dogecoin, Worldcoin, Feathercoin, Casinocoin

I have configured Grandcoin and Frankocoin but have a few issues getting these up and running. The process runs ok but all my stats are blank.

If anyone wants to trade coin settings or work on this together let me know. Lets work on expanding ALT coins available on P2Pool sites. It benefits us all.

Im also hoping to roll out Earthcoin soon.

If you want to discuss further PM me or hit me up on Skype. My Skype ID is SEOCrow

I certainly would be interested in doing that. Timing is key though. I too have tried to get earthcoin going but there is an issue with the p2pool code and the wallet. I've been running into sporadic disconnects. The post above me details that, but I'm sure with the right people, this can be overcome.

I'm in CST time and cane be available during the day tues and thur or perhaps on a weekend or late weeknight.

Hey

Also interested in this... skype: kh4n2k8
Maybe we can get some interest / support from rav3n or cartman in maintaing a GIT for as many cryptos as we can manage.

I can help with providing stable/high-speed hosting for the nodes... as well as tinkering with the source files.


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: CartmanSPC on December 31, 2013, 11:43:45 PM
For those having problems I was curious as to what version of the p2pool source you were trying to use? Have seen that the latest version of p2pool (13.4) requires later versions of BTC and LTC wallets. Perhaps the ALT coin wallets you are using may not be compatible with 13.4. Try p2pool version 13.3 or earlier.


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: seocrow on January 01, 2014, 12:36:16 AM
Hi Cartman

Im using this version currently. Im willing to try some older versions if you think this could be why we are hitting these issues

3.3-96-g7f43101-dirty

Post by: yahma on January 01, 2014, 01:59:40 AM
rav3n git is on 13.4 and cartman-git is on 13.3

Found that syncing casino coin using (13.4) to 13.3 nodes does not work, unless you first copy the data from an existing 13.3 to 13.4 install.

@squiggie I think everyone here would be interested in syncing to common optimized configurations.  Could you please post your settings for grandcoin and other?  if you need to skype: gururise1

Why not IRC?

I don't really have a issue with communicating in both. However I do feel like the irc #p2pool and #p2pool-alt channels get a little crowded with the block announcements and make it hard to have a conversation sometimes, especially if the conversation spans for a while or if people afk for a bit and then come back into it.

Code:
   bitcoin=math.Object(
        PARENT=networks.nets['bitcoin'],
        SHARE_PERIOD=30, # seconds
        CHAIN_LENGTH=24*60*60//10, # shares
        REAL_CHAIN_LENGTH=24*60*60//10, # shares

        REAL_CHAIN_LENGTH=24*60*60//10, # shares
        TARGET_LOOKBEHIND=200, # shares

Trying to lock down two settings for p2pool.

The first is the last number in CHAIN_LENGTH and REAL_CHAIN_LENGTH. I hear that it should equal SHARE_PERIOD but see that both Bitcoin and Litecoin have both moved away from that keeping it at 10.

Second is TARGET_LOOKBEHIND. Can anyone explain that setting? I hear that it is the number of shares back p2pool uses to adjust the share diff. and have seen some people starting to use lower values to cause the share diff to adjust faster. I am not sure if that is a good idea since 200 shares is already rather low.

I am going to join this topic and added cartmanspc and CryptoCrow to skype. Hope you guys will add me so I can join the discussion there as well.
It annoys me hugely that there isn't a proper post or guide which explains all the various networks.py settings in detail.

Exactly. And then everybody's wondering why p2pool isn't used more.
I've been trying to get some p2pool nodes up and running for new coins, but it's a pain...

Post by: mapleshadow on February 01, 2014, 05:31:02 PM
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.

Code:
Testing bitcoind RPC connection to 'http://127.0.0.1:5555/' with username 'user'...

2013-12-30 00:24:16.669050 > p2pool.util.pack.LateEnd:

Now, what I noticed is in the pack.py file, the functions
Code:
def _unpack(self, data, ignore_trailing=False):
        obj, (data2, pos) = self.read((data, 0))

        assert data2 is data

        if pos != len(data) and not ignore_trailing:
            raise LateEnd()

        return obj

 def unpack(self, data, ignore_trailing=False):
        obj = self._unpack(data, ignore_trailing)

        if p2pool.DEBUG:
            packed = self._pack(obj)
            good = data.startswith(packed) if ignore_trailing else data == packed
            if not good:
                raise AssertionError()

        return obj
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.

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

        DUST_THRESHOLD=1e8,
    ),

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 (https://github.com/forrestv/p2pool/issues/151) on the official p2pool github in case anyone wants to contribute.

Developers of new alt-coins should also release the right p2pool config immediately when a coin is launched.
This should become a standard practice, so that every p2pool node uses the exact same configuration creating one homogeneous mega pool. I've seen multiple p2pools for the same coin because multiple persons create different configurations. P2pool is pretty useless if the nodes for the same coin do not all act as one.

I like p2pool a lot but I still fail to find correct configurations for new alt-coins.

Yes I agree completely! How can we enforce this?

So, I had a little chat with forrestv! Here is some information on how to find the correct settings for the /bitcoin/networks.py file.

Attention: the /bitcoin/networks.py is COIN SPECIFIC

Sample /bitcoin/networks.py:

Code:

<COINNAME>=math.Object(
        P2P_PREFIX='<HEX CODE>'.decode('hex'),
        P2P_PORT=<COIN PORT>,
        ADDRESS_VERSION=<X>,
        RPC_PORT=<RPCPORT>,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            '<lower case coin name>address' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: <X>*<TOTAL COINS> >> (height + 1)//840000,
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),

Detailed explanation

P2P_PREFIX = <HEX CODE>
pulled from ./src/main.ccp (search for "unsigned char pchMessageStart" and use the value between { } (remove all 0x))

P2P_PORT = <COIN PORT>
pulled from ./src/protocol.h (search for "GetDefaultPort", 2nd value will be the port value.)

ADDRESS_VERSION = <X>
<X> pulled from ./src/base58.h (search for "PUBKEY_ADDRESS")

RPC_PORT = <RPCPORT>
pulled from ./src/bitcoinrpc.cpp (search for 'GetArg("-rpcport", xxxx)' where xxxx is the value of the port.

RPC_CHECK change e.g. 'litecoinaddress' to '<lower case coin name>address'

SUBSIDY_FUNC = <X>*<TOTAL COINS> >> (height + 1)//<HEIGHT WHERE BLOCK HALVES>
<X> pulled from ./src/main.cpp (search for "nSubsidy")
<HEIGHT WHERE BLOCK HALVES> pulled from ./src/main.cpp (search for "nSubsidy >>= (nHeight")

note: If there is no "halfing" you should take out the ">> (height + 1)//<HEIGHT WHERE BLOCK HALVES>"

BLOCK_PERIOD = <SECONDS>
<SECONDS> pulled from ./src/main.cpp (search for "static const int64 nTargetSpacing")

SYMBOL = <COIN SHORTNAME>
Like BTC, LTC, DOGE

CONF_FILE_FUNC = change <WINDOWS FOLDER NAME>, <OSX FOLDER NAME>, <LINUX FOLDER NAME> and <CONF FILE NAME>

BLOCK_EXPLORER_URL_PREFIX = <URL OF BLOCKCHAIN INFO>

ADDRESS_EXPLORER_URL_PREFIX = <URL OF ADDRESS INFO>

TX_EXPLORER_URL_PREFIX = <URL OF TX INFO>

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 = 0.03e8
No changes for scrypt.

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 (current 0.1000).

Transaction fees in Litecoin have been designed to protect the network from a problem known as transaction spam (dust transactions). If someone was to setup a loop between two wallets, sending back and forth small amounts, they would grow the block chain. Fees prevent this as it becomes too expensive to do this.[/size]

I will soon follow up with details about the /networks.py file which is not coin specific but p2pool specific and thus different from /bitcoin/networks.py!
/networks.py contains the SPREAD value etc.

Good stuff tvb.

I have considered starting a new thread outlining the values with the OP being updated as needed but will start by making a few comments on yours.

Quote
P2P_PORT = <COIN PORT>
pulled from ./src/init.cpp
Pulling from that location IMO is not a good idea. Better to pull from the actual code "use" than the notes field in init.cpp.
You can find the P2P_PORT in the coin's source code in the protocol.h file, it's the 2nd value after GetDefaultPort.

Quote
RPC_PORT = <RPCPORT>
<PORT> pulled from src/init.cpp (search for "-rpcport")
Again, pulling from that location IMO is not a good idea. Better to pull from the actual code "use" than the notes field in init.cpp.
You can find RPC_PORT in bitcoinrpc.cpp file, look for GetArg("-rpcport", xxxx), where xxxx is the port.

Quote
DUST_THRESHOLD = 0.03e8
I understand why they want to do this for Litecoin and Bitcoin but for most alts I feel this setting is too high (or low depending on how you look at it). I think most smaller miners (which is what were really addressing here) would appreciate more consistent payments in smaller increments rather than fewer larger payments. I use DUST_THRESHOLD=1e8

Fewer (but larger) payments (I feel) puts off miners. Yes, it does increase the number of transactions in their wallet and may cost them more in fees when they try to use them but implementing coin control from newer litecoin releases can help there. They can also split up their transactions or wait for sufficient coin age.

Ok, those are my inputs. :)

...

I agree, although forrestv really should add it to the p2pool wiki or p2pool.info website
And you are right. 'pulling' the actual configured values from the source is better. Thanks for that!

I think we can now focus on the p2pool specific networks.py values..


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: mmouse on February 07, 2014, 09:08:17 PM
Developers of new alt-coins should also release the right p2pool config immediately when a coin is launched.
This should become a standard practice, so that every p2pool node uses the exact same configuration creating one homogeneous mega pool. I've seen multiple p2pools for the same coin because multiple persons create different configurations. P2pool is pretty useless if the nodes for the same coin do not all act as one.

I like p2pool a lot but I still fail to find correct configurations for new alt-coins.

Yes I agree completely! How can we enforce this?

I think
https://github.com/Rav3nPL/p2pool-rav.git
has the most complete network.py files for most altcoins. So if you want to add a new coin, probably the best way would be to clone that and do a merge request afterwards. That way there won't be 1001 different versions of p2pool on github, each of them working for exactly one altcoin ;)

Just my 2 cent.

... and thanks a lot @TVB for the hard facts.

Yeah, only if people would submit a merge request. That would be ideal.
I will probably start a new fork especially for that.

Post by: CartmanSPC on February 07, 2014, 10:03:34 PM
One of the problems is that coins occasionally change specs (DGC, WDC, CRCx2 and soon CSC...of the ones I track) and p2pool has to be updated to those new coin specs. It is a very hard job to keep up with everything :)

I try to stay on top of the coins I use in my git.


Title: Re: Finding p2pool networks.py values for new altcoins
Post by: tvb on February 07, 2014, 10:21:12 PM
Well, imo that is the responsibly of the coin developer(s). They should submit a merge request then.

As an example...I believe Ravs git has old specs on some of the coins.

SUBSIDY_FUNC = <X>*<TOTAL COINS>
<X> pulled from ./src/main.cpp (search for "nSubsidy")
<TOTAL COINS> total number of minable coins.

I believe this is incorrect. I think the correct way is:

for litecoin:
SUBSIDY_FUNC=lambda height: 50*100000000 >> (height + 1)//840000,
SUBSIDY_FUNC=lambda height: 'block reward' * 'satoshies' >> (height + 1)//'height where block halves'.

If there is no "halfing" you take out the >> (height + 1)//'height where block halves'

//840000 is the number from main.cpp in nSubsidy -> nSubsidy >>= (nHeight /

For SPREAD I use the following formula:

SPREAD=
600/[block time]=x
x*3=spread


Not saying that it is right but it's what I use.

Code:
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)
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)

Sadly when we did the first vertcoin nodes, we used spread=3 because we just copied litecoin. It really should have been 12-15... would avoid so much confusion for small miners right now. Doh.

You can lower your share difficulty by appending /diff to your p2pool username. That should generate more shares and more regular payouts, but of course you get paid less per share. I'm trying
Code:
VTCPayoutAddress+0.001465/0.55
at the moment. I can tell tomorrow, if this makes things better or worse...

address/diff won't let you set diff below the minimum share diff for the pool though. It's intended more to raise diff for giant miners than to lower diff, I thought?

First, I've to admit that I'm not completely sure about how p2pool handle diffs and so on, just my own code reading + try and error.

That said, pool minimum share diff (what you get e.g. with http://vtc.coinpools.de:9171/difficulty) is not what p2pool gives out to your miner as share difficulty (main reason, why the "share difficulty" displayed on the standard web client page is nonsense). p2pool uses a quite complicated algorithm to compute pseudo_share_difficulty (work.py lines 265-) and share_difficulty (data.py lines 111-) specifically for your miner client (see debug.log "New work for worker" entries).

IMHO the main problem with this is, that p2pool tries to dish out share difficulties so that it expects no more than one solved share per minute from all connected clients. So as my VTC node has about 6 MH/s local rate at the moment, the log shows a standard share difficulty of 1.39 given to clients. Minimum share difficulty for the pool is 0.063 on the other hand. So it seems perfectly legit to specify a custom share difficulty of 0.55 for my miner. (If you specify it too low, p2pool seems to use the minimum pool difficulty anyway).

Post by: roy7 on February 08, 2014, 06:37:22 PM
Hmmm. Even if I try to set /.00001 I can't see it changing anything on my miner's end. Using + of course submits diff 1 pseudo-shares constantly which is a waste of resources.

Looking at all of the New Work messages, they aren't all being set to the same difficulty. On my pool most are set to 0.00244 but one is .000812 and one is .000244. I assume those are the pseduo share difficulties and the tiny ones are the two slowest miners in pool?

Because yes, there is also the "Share difficulty: 1.918" which is going to all but 2 miners. One is me with my /.000001 forcing it down to match share difficulty. That other must be you or someone like you, setting a lower share difficulty with ADDR/ which means you'll actually have reduced variance since the difficulty chosen is still over the minimum.

Is it really 1 share total from all miners combined, or 1 share per minute from each miner individually? The latter would make more sense to me, but I'm thinking of it from a "running a pool-like public node" perspective. p2pool is designed from a "run it as a reduced variance solo mining operation" perspective.

Interesting. I kept assuming small miner variance was due to large share difficulty but that's not the case at all for VTC right now, if you are a small miner using a big public node.

2014-02-08 18:41:03.086159 New work for worker! Difficulty: 0.001676 Share difficulty: 1.505790
2014-02-08 18:41:03.287006 New work for worker! Difficulty: 0.001676 Share difficulty: 0.058060

I have a couple dozen lines similar to the first. The 2nd is my testing with difficultly forced as low as it can go. Being a single GPU miner, 1.5 (98683) will take me far far longer to get 1 share than .058 (3805) would.

Edit: Apologies for the thread hijack. mmouse we should move this to the P2Pool main thread or to the VTC thread.

SUBSIDY_FUNC = <X>*<TOTAL COINS>
<X> pulled from ./src/main.cpp (search for "nSubsidy")
<TOTAL COINS> total number of minable coins.

I believe this is incorrect. I think the correct way is:

for litecoin:
SUBSIDY_FUNC=lambda height: 50*100000000 >> (height + 1)//840000,
SUBSIDY_FUNC=lambda height: 'block reward' * 'satoshies' >> (height + 1)//'height where block halves'.

If there is no "halfing" you take out the >> (height + 1)//'height where block halves'

//840000 is the number from main.cpp in nSubsidy -> nSubsidy >>= (nHeight /

But I found if use p2pool setup by myself the HW error is very high from the output of CGMiner.

I can say I have seen this several times myself, unfortunately not 100% sure the cause of it quite yet and has not happened everytime so have not found the pattern yet.

Someone say getting work with 0 diff causes errors but I have no idea if it is HW errors or something else. Try connecting to your node with /.00001+.00001 if you use a scrypt based coin. (/1+1 if a SHA based coin). That will make sure you never get anything below 1 diff.

Have seen this happen on the first miner to join a node. I forget the exact message but also notice something like "unidentified stratum" in the console when this happens.

Simple quick fix (for me) is to restart the miner.

Q1) Can someone let me know how to get the Prefix and the Identifier for a new coin? (specifically litebar)

Q2) I have done the settings (except for prefix and identifier) to the best of my ability with the aid of this thread for Litebar network.py in both P2Pool locations. Can some bright spark actually post the correct settings for Litebar please. I have spent 12 hours trying figuring it out and could use any help.

Code:
   litebar=math.Object(

        P2P_PORT=19065,
        MIN_TARGET=0,
        MAX_TARGET=2**256//2**20 - 1,
        PERSIST=true,
        WORKER_PORT=19055,
        BOOTSTRAP_ADDRS=''.split(' '),
        ANNOUNCE_CHANNEL='',
        VERSION_CHECK=lambda v: True,

    ),

 


    litebar=math.Object(
        P2P_PREFIX='fbc0b6db'.decode('hex'),
        P2P_PORT=9065,
        ADDRESS_VERSION=48,
        RPC_PORT=9055,
        RPC_CHECK=defer.inlineCallbacks(lambda bitcoind: defer.returnValue(
            'litebaraddress' in (yield bitcoind.rpc_help()) and
            not (yield bitcoind.rpc_getinfo())['testnet']
        )),
        SUBSIDY_FUNC=lambda height: 2*100000000 >> (height + 1)//438000,
        POW_FUNC=lambda data: pack.IntType(256).unpack(__import__('ltc_scrypt').getPoWHash(data)),
        BLOCK_PERIOD=180,
        SYMBOL='LTB',
        CONF_FILE_FUNC=lambda: os.path.join(os.path.join(os.environ['APPDATA'], 'litebar') if platform.system() == 'Windows' else os.path.expanduser('~/Library/Application Support/litebar/') if platform.system() == 'Darwin' else os.path.expanduser('~/.litebar'), 'litebar.conf'),
        BLOCK_EXPLORER_URL_PREFIX='',
        ADDRESS_EXPLORER_URL_PREFIX='',
        TX_EXPLORER_URL_PREFIX='',
        SANE_TARGET_RANGE=(2**256//1000000000 - 1, 2**256//1000 - 1),
        DUMB_SCRYPT_DIFF=2**16,
DUMB_SCRYPT_DIFF=0.03e8,
    ),

I know some of these settings are ball park figures, and some of these setting might be completely wrong. Any help would be appreciated. Thanks

This is what happens when I run it - I get all Succcesses at the top but then I get this repeatedly:

Any ideas?

EDIT: Its works I think, I just pointed my miner at it. I'm getting a bunch of HW issues but I'll sort that out.

When I tried starting a Litecoin p2pool earlier I wasnt getting the above messages that I am getting with Litebar. Not sure why.

Right I have this kinda working, finally.

I was getting a bunch of hardware issues until I put +16 after my username in my cgminer conf file. However I dont think this is the permanent solution. I think its a setting on the server that needs to be corrected to may be allocate the difficulty better. I think its one (or more) of the settings to do with ~/P2Pool/P2Pool/Network.py

I will tweak them, however if anyone has any ideas on which ones I should be fiddling around with, please let me know.

Muchos gracias amigos.

When you first connect to a new node and there are no stats at all you will get served DIFF 0 work which will cause HWs in some types of miners. If you mine for a while with any + it will get some stats stored, then you can disconnect and reconnect without the + and you should be fine, with vardiff giving you pseudoshare targets above 0. I just put in a suggestion to the p2pool repo that the minimum work ever served should be 1 (for sha256) or 1/X where X is the scrypt adjustment to the difficulty figure for that coin (it's in bitcoin/networks.py).

I just immediately reconnect when that happens. Have not had to use + anything but then again I have 5 Mh/s so it may be adjusting higher faster for me so when I reconnect the pseudo diff is already primed to be higher.

The danger is like the guy who replied here

You probably recognize him from irc. :) If he falls over to a backup pool then much later back to his own node, it might do nothing but HWs all day until he can manually fix it because of the 0 diff issue.

Yes, that is a problem  :-\
Perhaps using cgwatcher can help. Not sure (haven't looked) but it may have a setting to watch for # of HW errors and restart the miner. If not then maybe we can make a feature suggestion.

Post by: Hyacin on March 07, 2014, 08:01:42 AM
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 (https://github.com/forrestv/p2pool/issues/151) 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 ...

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

        TARGET_LOOKBEHIND=50, # shares
        SPREAD=40, # blocks
        IDENTIFIER='4665617468657212'.decode('hex'),
        PREFIX='b131010ba6d472a9'.decode('hex'),
        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'),
        BLOCK_EXPLORER_URL_PREFIX='http://grandcoin.org/blocks/',
        ADDRESS_EXPLORER_URL_PREFIX='http://grandcoin.org/blocks/',
        SANE_TARGET_RANGE=(2**256//1000000000 - 1, 2**256//1000 - 1),
        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!

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:

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.

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?

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
 (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!

Cassey

Post by: CartmanSPC on July 16, 2014, 11:24:09 PM
Cassey,

Couple recommendations. Set the author donation to 0 as the payout address is most likely not valid. Make sure you have a unique IDENTIFER and PREFIX. If you like I can generate some for you but directions on how to do it are in the p2pool settings post I made somewhere on this board. Do not leave them the same or you may end up working on a different chain...

Edit: Found the post https://bitcointalk.org/index.php?topic=457574.0
