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

I see this line under current payouts.. is it anything to be worried about or is it someone just using a weird payout address?

Your solo mining, remember that. Therefor there is no payout address, but instead it goes directly into bitcoind.

[wachtwoord]

You can also specify a bitcoin address which is not part of the wallet of the bitcoind (or bitcoin-qt) which is currently running. I set it up this way after I got advise in the IRC channel that this is more secure (which I agree with).

[cabin]

Well actually each p2p block has hundreds of payout addresses, but you're right it is solo mining. My concern was if one funny payout address could drastically slow down confirmation of a found block and therefore result in a p2pool block being orphaned. For example if only 5% of the network supported P2SH addresses, and the p2pool payout list includes a P2SH-style address, then p2pool blocks would be very slow to transmit through the network.

I suspect it is nothing to worry about and that I'm missing something.. but I just wanted to bring up the possibility in case it is a potential bug/problem.

Ummmm? Eh?
It goes to all the N addresses listed in the share chain - the coinbase txn lists all those addresses.


Aside ... so as mentioned above ... could someone stop every block from being accepted by putting crap addresses in the share chain?
Hope that problem doesn't exist or has been already dealt with if it did exist.

I meant at least in our prospective. My payouts show as "Mined" in the bitcoin client.

Yes, but that is just a "bug" in the bitcoin client.  The actual generation transaction does include your address.  The client just doesn't show it to you.

I see this at the bottom of the table on this page.

I thought it was someone who had specified a bad address with the "-a" option. But that was just a guess. Smart people will help...

So I have p2pool running on an ubuntu server with python 2.7.

I wanted to setup a backup pool and so I installed everything on a debian server.  If I specify all of the command line options, it starts fine.  But "--help" gives an error.

Code:

Fixed, thanks for pointing that out.

Yay, I found my first block ever, just now, while participating in P2Pool. It took over 2 months at ~1710 Mhash/s.

Glad to see my mining rig can actually mine a full block

https://blockchain.info/block-index/867562/0000000000000943404156a9980c3c6e49b0f3c712a4c4673a6e8890edf9c13c

[Ente]

It gets more and more strange..

Rig "Miner04" uses forrestv-p2pool-0.8.4-1-gadba786
Rig "Miner03" uses forrestv-p2pool-release-0.8.1-0-gc7feb00

Rig "Miner04" uses Guiminer v2011-06-14
Rig "Miner03" uses Guiminer v2011-06-14

Guiminer "Miner03" --> p2pool "Miner03": finds "minerblocks" and "shareblocks"
Guiminer "Miner04" --> p2pool "Miner04": drops "unexpected error:" in guiminer
Guiminer "Miner03" --> p2pool "Miner04": finds "minerblocks" with 100% in (), finds "shareblocks"
Guiminer "Miner04" --> p2pool "Miner03": finds "minerblocks" with 50% in (), finds no "shareblocks"

So obviously its some problem on Guiminer's (or poclbm) side on "Miner04".

In Guiminer you see for example:

Accepted: 471 (256)
Stale: 0 (0)

I didnt find out what the number in () means, yet.

All other rigs are like "Miner03" and behave well.

Bah, I'm losing my patience with this windows stuff..

edits underlined

Ok, its quite clear now that its a problem on the Guiminer (or poclbm) side.
Will try to solve that and update all p2pool instances to the "forrestv-p2pool-0.8.4-1-gadba786" version too.

Thank you for your help!

Thanks, nice work.

But  how do you know you found it?

So you regularly control+f through your entire log? 

[jothan]

I do a grep on the log once in a while FOR TEXT CONTAINING "BLOCK" IN CAPS.

I must also admit I am having a bit of a boring day and obsessing over Bitcoin has become a hobby on those days.

[nelisky]

just did a grep -E "BLOCK|SHARE" and...

Code:

'GOT BLOCK FROM MINER' means you found a block.

'GOT BLOCK FROM PEER' by itself (without seeing the message above) means someone else found a block and they are just telling your node about it.

'GOT BLOCK FROM MINER' means you found a block.

No, the fact that he got the matching share right before it would indicate that he solved it. P2Pool should have displayed "GOT BLOCK FROM MINER" right before the "GOT SHARE" line.. not sure why he didn't quote that.

[nelisky]

Right, the FROM MINER came before the SHARE, so my human grep capabilities have been proven to be lacking:

Code:

2012-02-09 17:27:28.021783 GOT BLOCK FROM MINER! Passing to bitcoind! bitcoin: 6bdb99d5aab93a5cc5b36c427eb07657011f7354e92d81b47b1
2012-02-09 17:27:28.024363 GOT SHARE! c fd031bab prev af58e024 age 5.44s
2012-02-09 17:27:28.035106 GOT BLOCK FROM PEER! Passing to bitcoind! fd031bab bitcoin: 6bdb99d5aab93a5cc5b36c427eb07657011f7354e92d81b47b1

Still, I did match the share with the block, so maybe I get extra cookie points for that?
