Yeah I'd happily donate 2% of my shares to this project purely because of the massive benefits it gives. Also would I be correct in saying that since it's p2p there's no bitcoind server to pay for?
Everyone pays for the network infrastructure themselves, so there is central server, no central website, no monitoring or intervention required...

I would like to see it the way that the node responsible can decide if he wants to include transactions in the blocks he finds for the p2pool. Even grater it would be if he could decide if he wants to include transactions with no fees or only those with fees or only those with fees > X.XXXXXXXX BTC.
The p2pool node just follows your bitcoind's transaction acceptance rules. Patch it and you'll change what transactions p2pool includes. P2Pool just requests a list of transactions to include from bitcoind; it has no knowledge of their individual fees. I love the idea of this pool, but one thing that personally puts me off it is the 0.5% fee to forrestv. It's negligible I know, and I understand that you probably want a piece of the "pool operator pie" with some other pools charging 2% and things like that. But wouldn't it be better to have an auto-donate feature instead? (as in, auto-donating 1% of your shares to a forrestv donation worker)
I know I'd personally prefer that over a fee, mainly because it's not forced upon people. And you'd probably generate more from this "opt-out auto-donate system" than you would with a 0.5% fee.
The project to me seems to symbolize freedom from the mining pool operators and this fee kinda spoils it for me.
Any thoughts on switching to this?
I like this idea, and the p2pool protocol can be changed relatively easily (recently we switched from a 5 second share period to a 10 second share period with this change). This could be done in two ways: Each user could set the proportion of their individually solved blocks to donate, or each user could set the proportion of their work to donate. They should be equivalent in the long run, so I'm mainly considering which is easier to implement.

That's good to hear that it's flexible incase it need changes in the future. This could be done in two ways: Each user could set the proportion of their individually solved blocks to donate, or each user could set the proportion of their work to donate. They should be equivalent in the long run, so I'm mainly considering which is easier to implement. By solved blocks I assume you mean solved shares? I would've thought setting it proportionate to shares would be easiest, but let me know which one you decide!

How about including some transactions in the 4th block?! The future will need more fees than generation rewards... and you're missing the whole idea of mining...
If there are no transactions being recorded, that is a major design problem. this is currently being worked on. see https://github.com/bitcoin/bitcoin/pull/476 and the forum thread referenced therein. One hopes so. Until then, p2pool is actively DoS'ing the bitcoin network, by delaying transactions until a non-p2pool miner builds a block. That is very harmful to the network.

No, it isn't. P2Pool is contributing to the security of the network by building on existing blocks. As for delaying transactions, P2Pool running without including transactions is exactly the same as everyone using P2Pool just not mining at all. (Until the next difficulty change, at least.) Block generation is independent, so the average time to the next non-p2pool block is: 10 minutes / (1 - p2pool_hash_rate/total_hash_rate), which is currently equal to 10.01 minutes.

Sorry, but that is just spin. p2pool delays transactions, running directly counter to the service bitcoin users want to provide. This also sets an awful precedent: imagine more miners following p2pool's examples, or p2pool gains hash strength. There would be huge transaction delays. Failing to include transactions is harmful to the network, plain and simple.

And yes, if this problem is fixed -- p2pool includes user transactions in blocks -- then the objection is removed.
forrestv was indicating on IRC that a fix is being deployed... we'll see from the next block p2pool generates.

I believe that cgminer currently does not work with P2Pool. Any plans to correct it in the nearest future ?
PS. P2Pool is really a great idea, hoping that with time will develop and grow ...

I too think this is a great idea and would be willing to start mining with the network if the phoenix patch makes it to an official release and on to the bamt stack. Also, is there anyway to streamline the setup of p2pool? The setup while not difficult, still makes me hesitate, which IMHO will keep others from coming on board.

As far as I can tell, the patch to phoenix is a patch against an very out of date version of phoenix (forked from phoenix sometime back in July). "sleep" (the function for delaying) does not appear anywhere in the current version of phoenix or the aldyen fork of phoenix. I see no other indication that there is a delay after a long poll, either. I don't know what version is on bamt, but the latest official version of phoenix appears fine.

I was looking at this last night, and yeah, this is true. Sorry for letting it get so out of date! However, there are some other changes made to phoenix to reduce stales. I'm working on a new fork of phoenix at https://github.com/forrestv/Phoenix-Miner-new , and I'm going to submit some pull requests.

Nice, maybe is also a good idea to create something like best practices for p2pool ... I belive that more experienced users could share their knowledge regarding best miners & settings to optimize performance and (possibly) decrease amount of stales. For example - after two days of minning for p2pool i can tell that diablo seems to be the best option (patched version of course), however it's is not my favourite because its generating unnecesary burden on CPU (java - around 20%) and other weird behaviours, so I am looking forward for new phoenix... Screenshot from today (velocity of rig with phoenix: ~1450, diablo ~1390, p2pool after few hours shows values between 850-1200 MH/s ): 20:10:10.719807 Pool: 9550MH/s in 34645 shares (34649/34649 verified) Recent: 9.70% >926MH/s Shares: 304 (73 stale) Peers: 10 20:10:10.721351 Median stale proportion: 0.238506141756 20:10:10.721464 Own: 0.240131578947 20:10:10.721554 Own efficiency: 99.79% In case of phoenix published with patch so far - amount of stales seems to be higher than in case of diablo, I have been told that it can be improved by decreasing parameter AGGRESSION from 12 to 7, but after that my cards works on 80-85% so its waste of resources and i don't like it at all Cgminer - 2.x.x does not work (older version not checked) despite of info on p2pool mainpage. Checked with forrestv-p2pool-19b86ed.tar.gz ( https://github.com/forrestv/p2pool/tarball/19b86ed6d0b3c3a98f6199db7377a0e170365cfd) Fellow miners - please do not hesitate to share with us ... newbies ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) , and remember that it also should help to avoid annoying and recurrent cuestions from us on IRC .. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) Thats all for now, hoping that it will help someone ...

cgminer 1.5.8 seems to work for me but not, as you note, the newer versions. I was getting very low stale rates (usually around .12-.18) until recently, where I'm getting around .4 rather than the ~.2 median - not sure what changed but at least it still works?

I'm mining with p2pool, running forrestv-p2pool-27ab63b / forrestv-poclbm-5590e7c on radeon 5850 on ubuntu 11.04 64bit. Box is a dedicated miner. Seems there may be some stability problems. Indicated hash rate changes dramatically. With a straight forward: ./poclbm.py -d1 http://etc etc ... sometimes I get: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fjonathanriley.net%2Fimages%2Ftcoi%2F0.png&t=665&c=n7ep6SuqEnk9SQ) ... other times i get: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fjonathanriley.net%2Fimages%2Ftcoi%2F589.png&t=665&c=331ziIMS9LUEPQ) ... and other times I get anything in between. 70 MH/s showing right now.
