P2Pool is a peer to peer mining pool, offering some advantages over centralized pools:

How can I find out how many people are using P2Pool?

  • As currently phrased, this is fairly localised in time. What's the enduring question here? Commented Sep 8, 2011 at 18:28

    @eMansipater - "How should I talk to a database in Java" is also time-dependent, but that doesn't mean it's not a good question. I'd like to know the answer now - and if it change, let's change the accepted answer.

  • "Is X being adopted?" changes monthly if not daily. Talking to a database in Java, not so much (but that's still not an amazing question for SO. Much better would be "How should I talk to a database in Java in the following situation?" or "Which ways of talking to a database in Java meet the following criteria?" etc.) Commented Sep 8, 2011 at 18:50

    @eMansipater - perhaps "How do I find the hash 'market share' of P2Pool?"

    You can find a graph showing the hash rate of the pool over time here: forre.st:9332/graphs (or at localhost:9332/graphs if you're running p2pool on your own machine). Commented Feb 13, 2012 at 6:05

In concept, P2Pool is much stronger than centralized pools. Unfortunately, most centralized pools still hold a high hash-rate.

You can see the global hash rate, and its distribution at http://bitcoinwatch.com/

My opinion is that miners are used to using slush, deep bit, and btcguild - and are either unaware of the incentives of P2Pool, or don't care.

  • Is P2Pool cheaper than other pools? Can it be?

  • The largest reason miners use the "big 3" is reduced volatility. Now medium sized pools w/ various "pay per share" methods have reduced that demand somewhat but p2pool is proportional and in proportional pools size matters. Commented Oct 13, 2011 at 17:48

    @ripper234 P2Pool charges a voluntary 0.5% fee, so it's much cheaper than some other pools. Deepbit charges 10% for example. Commented Feb 13, 2012 at 6:07
