Hi, i'm from venezuela and i have a large farm. But really i don't understand how can i mine with p2pool, i need to know if you can help me with my problem. I want mine with my own p2pool node but i need an interface for stats. I researched but do not quite understand how. someone you could guide me ?
Thanks

tutorial (sorry in french) : https://bitcointalk.org/index.php?topic=1114415.0
i mine on my own P2Pool server since 2 years.

It seems to me that as the difficulty increases the overall p2pool hashrate decreases. Why is that?

Network difficulty increases as the network hashrate increases, so perhaps miners on p2pool are just keeping up with the rest of the network.

Less miners equals less hash rate.  Down to 136 from over 250 only months ago.  The culprit is the 3 day work drop-out.  That period should be based on average days to block, IMO, although that might not be feasible.

@organofcorti  Ummm, I was asking for people's thoughts regarding why p2pool's hashrate is decreasing as the the network difficulty is increasing which is not the same as p2pool keeping up with the rest of the network. It is quite the opposite actually.

P2Pool has a share life of either three days or three times the average work to find a block, whichever is lower.

Thanks, I was not familiar with the specific algorithm for share life.

Is it time to increase the Three day limit to Seven to be more realistic of current block time; and, if it is, is this something that can be changed slowly as part of a natural rollout or would it require a hard cutover ?

After reading ck and jonny explanation about difficulty scaling issue, isn't it the time to move to other pool ?

p2pool is a great concept but unless the dev come up with a solution for difficulty scaling. It can't go any further.
Maybe it couldn't be fix, who knows...

There are plenty pools that could use your hash power:

Interesting there are suddenly a bunch of noob accounts encouraging folks to jump ship...

The scaling issue is only an issue if p2pool has substantially more hash rate then it currently does.

The current problem is our hash rate is simply to low to find regular blocks, 1 decent sized miner can fix that.

ck, could you kind enough to explain to me about this scaling issue, preferably in noob wording lol...
In a regular pool, the more hashrate the pool has, the less variation there is in each miner's payouts. In p2pool it is biphasic. Initially as the hashrate of the pool increases your variation decreases, and then as the hashrate gets larger again, variation starts increasing again. If all miners were on p2pool, it'd be like they were solo mining at 1/20th of the current network diff which would be horrific variation. It's one of the limitations of the p2pool design that's been talked about, thrashed out and debated about for years on end without a solution.

Isn't an easy solution to too much p2pool participation just to have multiple separate p2pools? I think there are some alts where p2pool got really popular which have done that.

The game theory on this works quite nicely in fact, since being on a p2pool that is too small or too big are both undesirable, so miners will tend to spread out.

Of course, the current problem is too little participation, not too much.

Yeah separate p2pool is one of the idea I think.

That is true, spread out miner is good I think.

This is the biggest problem of all in p2pool. Lets face it, why do we buy ASIC miner? I believe the one who buy ASIC miner already done some research and reading how many btc we could get with the miner, how much electricity cost, etc. How long will ROI... current p2pool payout is based on 3 days worth of share. but with the pool current hash rate, it will hit the block around 10-12 days (according to what was written on the web front end). I don't think you can cover your electricity cost with this unless you have either super unbelievable cheap or free electricity.

I don't know how high the hash rate in p2pool to make the difficulty undesirable but as of this posting date, if it can reach at least 50 Ph/s and it still desirable (good variation) then it should be all good.

Hey we found a block! Smiley

Of course I'm out of town and my site is reporting it incorrectly as one orphan and one found block, I'll get it sorted on Friday when I return, but hey, we found a block!

Block....

Did P2Pool just mine empty block?

When P2Pool learns that there's a new block, it mines empty blocks until bitcoind gives it a block template.

The alternative to doing this would be to mine orphaned blocks rather than empty ones. :/
