[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[spiccioli]

Right. The question is, is tuning the block sizes causing a problem with p2pool? Is that the "bug"?

No, tuning the block size changes the number of transactions that will be included in your block when you find one.

Adding that to the my mining on P2Pool FAQ.

[Nite69]

Is this correct place to send error logs? Anyway, here it is (Litecoin mining, Ubuntu linux 64 bit, Python 2.7.3, p2pool 11.2, cgminer):

Did I just miss a block reward?

If this "method not found" error is just after you start node - ignore it.
If it shows up after few hrs of minig - something is wrong.
Try this git tree: https://github.com/litecoin-project/litecoin/tree/0.6.3

[Nite69]

After I start p2pool one error, this one (not the same) every now and then. During last night, there has been a lot of them ('new errors' end the ones that come after retry).
Also, 7 found blocks @ 150Khz during 0.300 days (;.D), so if it is when submitting blocks, it does not fail all.


Counted 11 group of errors on the log, so most likely i have not missed real blocks. On my hash rate it is too much and 7 found is somewhere in the correct scale.

The error that comes at the start, has been there also once during the night.

Well, I'm already running litecoin wallet from latest git. Is there specific version of p2pool for litecoin mining?

Anyway, now running latest git p2pool, version is Version: 11.2-2-g77e7e2a. Seems to log a lot more..

If you want to test it, try http://p2pool.cave.dy.fi:9327 As usual, your receiving wallet address as username with any password. This is just testing, so I cannot guarantee any uptime, have your backup pool ready.

Fee is 0.4 + 0.4 to authors

Edit: gave it a second thought and closedit. Do not know enought about this to open it widely on the net.

litecoin 0.6.3 is NOT a main tree branch.
Try download and compile it, I have no errors on it.

Ok, now running, but it says version is "v0.6.1-670-g7fd4c83-beta"

Edit: And soon (now officialp2pool 11.2). Looks like some incompatibility with python libraries?:

And immediately after it, i got a litecoin transfer to my wallet?

btw, timestamps on litecoin log would be nice..

Update: Yep, it happens every time p2pool finds a block. Happened with last two block 11.07 and 13.05 (UTC+2). BUT there is one more, and at that time p2pool did not solev a block. It happened at

Code:

2013-03-16 12:37:14.524647 > Error submitting block: (will retry)

Does that mean one p2pool solved block did not find it's way to litecoin blockchain?

Here is the block id (interesting.. that block might be worth a look):

Code:

wow, while writing this, pool solves one. And again the problem. litecoin-qt log:

update: so there was a non-p2pool block on the p2pool network. One of these is not p2pool blocks.

As I mentioned in a previous post, http://p2pool.info is a web app that is hosted in the cloud, but it depends on bitcoind and p2pool servers running in the basement of my home.  That means when I have power or internet disruptions at home, the site stops being accurate.

I have been working on making the web app independent of my home's servers and I'm nearly done.  It now finds blocks exclusively by using the blockchain.info APIs instead of a bitcoind server in my house.  The last part of my work is to make it not depend on the p2pool server in my house either... 

There is an old thread here that lists public p2pool servers, but it is so old that I don't trust it.  Does anyone still run a public p2pool server that they intend to keep around?  Ideally, I'd like a list of 3+ of them so that p2pool.info wouldn't be dependent on any p2pool server.  All that p2pool.info uses the p2pool API for is to get the pool hashrate, user list, and payout list once every 5 minutes, so the traffic to your server would be very light and largely insignificant.

If you have a server that you'd be willing to let p2pool.info use, please let me know here or via PM.

Hi!

How is this supposed to work? I do not understand how it could have been implemented. Also, it does not seem to work on litecoin p2pool.

  -f FEE_PERCENTAGE, --fee FEE_PERCENTAGE
                        charge workers mining to their own bitcoin address (by
                        setting their miner's username to a bitcoin address)
                        this percentage fee to mine on your p2pool instance.
                        Amount displayed at http://127.0.0.1:WORKER_PORT/fee

if you set the fee percentage to 1%, then 1% of shares (randomly) will be allocated to the address specified on the command line (with -a) instead of to the address passed in by the miner as the username.

Yes, of course, ty anyway. Found it on the code:

Debugged this a little more. Well, there is not submitblock rpc method on the litecoin! :-( This means it is not working anywhere. But then how the blocks get into litecoin block chain?!

    { "listsinceblock",         &listsinceblock,         false,  false },
    { "dumpprivkey",            &dumpprivkey,            false,  false },
    { "importprivkey",          &importprivkey,          false,  false },

Code:

    { "getblocktemplate",       &getblocktemplate,       true },
    { "listsinceblock",         &listsinceblock,         false },

submitblock is relatively new in bitcoind.  In litecoind it's done with getblocktemplate, passing the first argument (mode) as submit, and the second argument (data) as the hex data of the full block.

[Nite69]

submitblock is relatively new in bitcoind.  In litecoind it's done with getblocktemplate, passing the first argument (mode) as submit, and the second argument (data) as the hex data of the full block.

That means there really is a compatibility problem between latest p2pool (11.2, possibly earlier) and any version of litecoind. Maybe users should be adviced not to update to latest p2pool with litecoin. If everyone updates... litecoin p2pool stops getting any blocks :-(

[K1773R]

this happens sometimes, start litecoind first and then start ltcp2pool, that should fix it.

[Nite69]

submitblock is relatively new in bitcoind.  In litecoind it's done with getblocktemplate, passing the first argument (mode) as submit, and the second argument (data) as the hex data of the full block.

Thank you, fixed it by changing one line in source:
helper.py, line 73:
was

Code:

        #result = yield bitcoind.rpc_submitblock(bitcoin_data.block_type.pack(block).encode('hex'))

Fix:

Code:

	result = yield bitcoind.rpc_getblocktemplate(dict(mode='submit', data=bitcoin_data.block_type.pack(block).encode('hex')))

Of course, I don't know if this works on bitcoin p2pool any more. Someone into this make this and add correct checks (litecoind/bitcoind (terracoin/ppc?!) mode, other end version etc..)

Seriously, the rpc interface should give a version number so the client could choose correct method to use.. Current one this is a mess and very difficult to do (litecoind/bitcoind) version independent code :-(

Testing is a bit slow, allways need to wait for p2poop to find a block...
