The others explained it much better than I could.  What I said was true, if you stuck with it during the rough periods, you still got the normal full payout.

This is 100% incorrect. It is a mathematical truth that you will receive more BTC mining p2pool with its internal 10% rejects than you would a pool with a 2% fee if you have an average p2pool node. This is because the 10% "rejects" p2pool reports are internal share rejects in the p2pool network that has nothing to do with BTC production.

p2pool has it's own blockchain independent of BTC's blockchain. p2pool's blockchain finds a block every 10 seconds, and therefore, because of network latency, explains a ~10% chance of collision/orphans in p2pool's blockchain. That does not mean that 10% of p2pool's BTC blocks being rejected.

As long as you have a health node, you will see ~10% rejection rate of internal p2pool shares, but the overall orphan rate of p2pool is always identical to the BTC network orphan rate (~1%).

Example:
Two miners hash in a fee pool and in p2pool. Miner A hashes at 100 GH/s, Miner B hashes at 200 GH/s. Both pools find a block at the exact same rate. block reward is 25 BTC and there are .3 BTC of fees. Ignoring the BTC-wide orphan rate of ~1% but considering the p2pool internal share orphan rate of 10%


Fee Pool:
total reward: 25.3 BTC-0.3BTC-.5BTC=24.5
Miner A= 100GH/s divided by (total hash speed)*reward = 8.2 BTC
Miner B = 16.3 BTC

p2pool
total reward: 25.3 BTC
Miner A = 100 GH/s*10% divided by (total hash speed * 10%) = 8.4 BTC
Miner B = 16.9 BTC


in reality, all payouts are also smaller (on average) by 1% to include the affect of the internal BTC orphan rate which is impossible to get around.

you have to understand that p2pool isnt mining the bitcoin chain it's mining an alt chain that essentially merge mines the btc chain. rejects, stales and orphans don't matter as long as the pool is working. You can get a btc block with a stale or orphaned p2pool share. There's a lot of variance because of the share idea, but it works out. As long as you get some shares in before p2pool hits a block you are good. The shares last for several blocks, so if you stop mining you get paid for a while too. It also means it takes a while to build up your sharecount to reach maximum payout.

90% of my work to p2pool is discarded work or rejected shares, because of the 10 second long polling. I still have been making far > 110% PPS and AFAIK no public pool can touch that anymore.

If you had been on p2pool the last couple months you'd have made 110%+ over regular PPS rates, without fees mined straight to your wallet.

I guess he means that if EVERYONE was getting the same 10% rejects, and those 10% reject don't result in a 10% drop in blocks found, then theoretically the rewards still get divided up the same? So as long as you're not the only person getting 10% rejects, then it doesn't matter to your payout? Idk I'm a little confused by that as well. 

Getting paid and getting paid your full expected amount is not the same thing. I'd rather be at a pool like BTCOxygen with a 2% fee than get 10% rejects.

I know.  Check the stats:

http://p2pool.info/

Pool stale rate was 20-30% for a long time, miners were getting 10% rejects from the pool, yet we kept getting blocks and getting paid.  What can I say, other than go p2pool.

Lol that's sort of a weird, confusing explanation.

The upgrade appeared bumpy, but still worked.  It didn't affect the block rate, it just looked bad to everyone.  People still got paid, if they didn't give up because it looked bad.

Wasn't P2Pool having some sort of problems recently? Idk where I heard that...

I know.  There are still a lot of GPUs out there though that could use it.

This will be difficult until ASICs come out because BFL FPGA Singles are incompatible with p2pool.

BTC Guild was being attacked and now the Germany server is offline.

At the end of the day p2pool might be the only pool left.  Decentralized/no fees/all transactions is hard to beat.  We just need more hash rate on it to decrease the variance.

M

I know Deepbit was getting attacked. OzCoin was having problems with some DNS issues. Neither of those was the pools fault. Combine that with maybe some bad luck from the other pools, and you've got yourself a "dip in the hashrate".

It THAT what happened.

I was wondering what in the world was going on.
I mean, 4.58 blocks per hour?
Estimated difficulty 3.51M?  A day ago it was 3.60M and climbing.

Meanwhile the BTC price has shot up almost $1 over pre-Halving levels.

A bunch of pools have been attacked/ddos'd today. I would almost expect it to return to it's previous level in the next day or so.

The hash rate dropped quickly below 20TH, more GPU miners are shutting down...

Two of my GPUs are already died and the third is on the way
