You still have the catch 22 problem if you bring in big mining operations like petamine: The bigger the p2pool hashrate, the harder it becomes for small miners. In precisely the opposite way from regular pools, the bigger p2pool is, the more it starts resembling solo mining for every miner. If the entire bitcoin network mined on p2pool, it would be like solo mining at 1/20th of the network hashrate (so like mining at a diff of almost 1 billion).

I have a question about fees.

Basically I want to know how they work.

I have a pool that has been running for a few days and 2 payouts have gone out of 0.002 each to the wallet address that is my BTC address.

I have a set a 5% pool fee as a maintenance fund, but nothing has gone to the p2pool address, how do fees actually work? I can seem to find anything documentation wise that actually explains how it works and how the payments are made, or more importantly when the payments are made.

I haven't set a p2pool address in the config in p2pool but it has picked one up from bitcoin as it connected using bitcoin.conf. Do I need to manaully say an address to use? in the p2pool config or is this address ok?

Thanks.

...how much of an advantage actually increases the worse their connectivity to p2pool is (assuming fully benign operators).

This is an interesting one, had to give it some thought... My assumption at his point would be that any latency to p2pool would also be reflected in bitcoind and perhaps remove any advantage they might have gained by causing orphan race losses for themselves on actual found blocks?

Also, its notable that there are a bunch of active nodes in China now, however this still might work in South America or Africa (Rio or Cape Town?) as I have not seen nodes there yet...

You still have the catch 22 problem if you bring in big mining operations like petamine: The bigger the p2pool hashrate, the harder it becomes for small miners. In precisely the opposite way from regular pools, the bigger p2pool is, the more it starts resembling solo mining for every miner. If the entire bitcoin network mined on p2pool, it would be like solo mining at 1/20th of the network hashrate (so like mining at a diff of almost 1 billion).

Agreed, but again, this is a problem I'd love for p2pool to actually have (on a bigger scale)...

The lower threshold for getting a payout in ~most~ blocks seems to be around 40 GH/s right now. Would bumping that to 80-100 GH/s by adding 1 PH/s to the network impact that many miners? It looks like under 2% of pool miners right now...

It is a very real challenge/problem, but I don't think it impacts that many miners, and the ones it is currently impacting would really not be contributing that much to the pool to begin with (I know poor excuse, I'd like to include everyone...).

Actually making the problem worse (by growing the pool speed and increasing the minimum effective hash rate per-miner) might also prompt more active work on a solution... Or slower miners could join together and simply create an alternate share-chain (I don't think this is the best long term solution, but it would work today...)

Again, agree its a real problem, but one I'd love for us to have it on a larger scale so that it might "force" a solution...

There are 2 types of fees you can set, one for forrestv (--give-author), and one for an address you designate (-f). If you do not set -f it will pull an address from bitcoind, this is not a good practice in my opinion as you don't want to keep any Bitcoin on a public p2pool node for security reasons.

Both fees work the same way, they are a % of found shares by the node, not an actual % of earnings... So in your case 5% of found shares would go to the address you designate with -f.

I'm curious how you came up with 40 GH/s?  I have one S1 (180 GH/s) that I'm not putting on p2pool because the variance is too much for me.  If my S2s worker properly, I'd put them all there, but they don't, so the S1 stays with my S2s.

It can be... I bought 2 S1s close to the end at .5, had a PSU, they have made ROI on p2pool:

It's actually -a to set the node payout address, -f is the fee %.

That is correct, good catch, thanks!

Ahhh ok that makes sense, so if I found 100 shares 5 of them would go to the pool

About 5... Also subject to variance so it not always exact...

Well we when your payouts drop like that the payout frequency corrects it, because at 1 PH we were at an 18-19 hr expected block time, not 1d 7hr.  So in the end you make the same.  Larger and less frequent, or smaller and more frequent, I'd actually vote for smaller and more frequent as that lowers variance.  So each share would get 3-4 payouts, not 2-3.
