[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[maqifrnswa]

...and people who've been mining on p2pool all year have made something like 12% more than they expected

How the heck is it possible to calculate that? Is this a sampled figure?

http://p2pool.info/luck/

you can calculate the total number of hashes in the year and the expected number of blocks. You can then count the total number of blocks actually found. You do that, and you get +12%.

How do you calculate the total number of hashes in the year? Aren't you just estimating this from the number of blocks/shares found?

What is really calculated is the number of hashes you'd have to perform to have a good chance of finding the same number of (different) blocks at the same difficulties.  That's cumbersome to say, so most people just shorten it.  Or they are confused.  Either way, when you see people say things like that, you need to expand it to the full phrase in your head when you read it.

thanks, yes - and p2pool has the extra data in that you can track the number of p2pool shares found, and the difficulty of those shares. So you look how many hashes are in those p2pool shares (effectively) and compare that to how many hashes should have been in the blocks you found. We have fewer calculated hashes in the p2pool share chain than is expected based on the number of real blocks that were found.

I was wondering when they were going to say something... I've sent my portion of the erroneous fee to them. I don't think they'll get it all back though. :/

At least now I know what happened with that transaction.

[dellech]

I just calculated my slice of the erroneous fee: 0.24946BTC  - and I will send it back !
Might take some time, I have to boot my cold wallet laptop when I come home from work today.

Anybody want to do the calculations to determine the list of addresses that benefited from his transaction fee and how much each of them got and post it here.  Seems like a good thing for the guy that goofed to do.  I don't feel like figuring it out, but if he'll show me, if and how much I got, I'll send it back.

Does the number of p2pool shares found include deads and orphans?

In any case, it sounds like what you're measuring is the luck in creating blocks vs. the luck in creating shares... At least, that's what you're measuring if you're including all the deads and orphans. If you're not including the deads and orphans, then your hash estimate is too low.

Is it even possible to measure deads and orphans? Not all of the network is necessarily going to see all of them...

good point - I'm not the one that quotes that +12% number, but that's about what the DOA+orphan rate is on the network that is also possibly viable blocks.

Does anyone know how p2pool.info does it?

A complete explaination is somewhere around page 100-120 I think

In a nutshell, the luck calculation is a comparison of the number of blocks that were actually found vs the number of blocks that should have been found (based on the pool's hashrate over time as reported by p2pool, itself).  When more blocks were found than were expected, luck is > 100% and vice versa.

Orphaned blocks are included in the count of found blocks because a block being orphaned or not has nothing to do with the mathematics of block finding probability and I wanted "100% luck" to equal "normal".  Certainly having blocks get orphaned is unlucky, but it's bad luck related to something different than the odds of finding a valid block.

Anybody want to do the calculations to determine the list of addresses that benefited from his transaction fee and how much each of them got and post it here.  Seems like a good thing for the guy that goofed to do.  I don't feel like figuring it out, but if he'll show me, if and how much I got, I'll send it back.

Here is the list 

Find your address, next to it the full reward you received and last on the line the coins you got out of the erroneous transaction (rounded down to the next satoshi 

Above the list is the link to the original transaction ...

Ok, for what it's worth I refunded my .012... amount.

It's that "hashrate over time as reported by p2pool, itself" that I'm asking about. This itself is, as I understand it, a calculated figure.

This answer raises another question, though. What's the "over time"? Is the time period that the hashrate was calculated over the same as the time period the number of blocks were counted over?

I guess the source code of p2pool would be the place to find the answers?

Both p2pool.info and p2pool, itself are open source, so yes, you can look at the code if you are curious. about the specifics

I don't know for sure how p2pool calculates pool hashrate for sure (forrestv will have to comment), but I generally understand it to be based on the number shares being found and I think it also includes some kind of adjustment to include DOA/orphaned shares as well.

p2pool.info collects and stores the hashrate of p2pool generally every 5 minutes. When a block is found, those 5 minute hashrate data points are used allong with the block's difficulty to calculate the luck of that "round".  Then, the luck of individual blocks are aggregated to come up with the 7, 30, and 90 day luck statistics.

[twmz]

If all of a sudden the network started finding lots of non-block-winning shares, luck would fall. If all of a sudden the network found fewer non-block-winning shares (but the same number of blocks), luck would rise.

Yes. This is why the hashrate graph shown in p2pool.info is "bumpy".  Hashrate is not really changing that much--it's mostly just luck/variance.

By the way, this is a limitation of all pools.  No pool knows how much hashing is actually being done by its miners.  Pools only knows what shares are being submitted then they estimate hashrates based on those submitted shares (and then they calculate luck based on those estimated hashrates).  Over a long enough period of time, the inherent share-finding-variance evens out.  So I personally have fairly high confidence that the 90 day luck number, in particular, is reasonably accurate and that the pool really did find about 18% more blocks in the last 90 days than it "should have".  Maybe the real number is 17% or 19%, but it's pretty close.

P.S.  I have no idea how p2pool knows the global DOA/stale rate, but it clearly does (or thinks it does) since it is displayed in the console output and is directly used to calculate efficiency.

Been trying to set up a few P2Pool nodes for mining alt-coins and I have some very basic questions that I can't seem to find the answers for. Hoping someone can chime in and help:

1. My first P2PNode is a private node and has the miner fee set to 2% (w/0.5% donation). I have a few miners mining for several hours and several blocks have been found, with payouts going to the miners; however, I have yet to see a payout to the payout address (current payout reads: 0).  Is this normal?  I thought 2% of each miner's payout would arrive at my set default payout address.

2. My 2nd P2PNode has miner fee set to 0%.  In this node, I should never see any payout to the default address (unless someone is mining with an invalid address), correct?

My concern is mainly with node #1 as why why I'm not seeing a payout at the default address. Does P2Pool payout the mining fee with every block found?  Or does it queue it up and send it later?

[dellech]

just to put my money where my mouth is    my share of the erroneous fee is on its way back !

p2pool can't pay fractions of a share, so the way it handles fees is that a 2% fee is that 2% of shares found by miners will be reassigned from the miner address to the node's address (randomly).  Because it is random, it will work out to 2% over the long term, but you won't see a consistent payment on a block by block basis unless you have a high enough hashrate that you're finding 100s of shares per block.

I guess this is what to look at next.... Or just let my curiosity on this one go.

Each P2Pool share has a flag for whether the node has an as-of-yet-uncounted orphan share. When computing the total hash rate, each share with that flag set is counted twice.

Not sure where else to ask this... but has anyone wrote a guide for p2pool and AM Blades/Cubes?  I assume I will need to use bfgminer?  I haven't seen much on how to get that to work with the Cube either...

Sorry if this has been posted already, but I couldn't Google worth a damn on this topic.

Makes sense! Thank you for the clarification.. so does it make sense for a miner to even mine on a node if he cannot hash fast enough to at least find one share per block?  I guess that miner would never get paid by p2pool if he never finds a share (due to a low hashrate)?

If you don't find shares very often, you won't always get a payment with every block.  When you do find a share, you'll get paid for the next several blocks (the number of blocks depends on how quickly they come, p2pool uses is PPLNS).  In the long run, it evens out, but the variability in payments (i.e. variance) can be very frustrating.  If that sort of thing seems like it would frustrate you, then don't mine on p2pool.  I, personally, wouldn't like the level of variance if my hashrate was only getting me 1 share every 12-24 hours (or worse).

Dear friends!
Could anybody explain this situation?

Hi,

I've just upgrared from version 13.3 to version 13.4 by replacing files in the program folder.

Immedaitely after upgrading current payout was reduced from ~1.2 to ~0.7LTC

http://i01.overclockers.ru/c3a4e04ba7baeac93b85adeaff0be886/mertamqqvnojf5bg.gif
2.7 MH/s, GMT+06

Why this happen? It must not reduce payout immediately, because payout is determined by previsously mined shares...

Thank you!

Is there any graph of share minimum difficulty over time?  In theory, if larger miners started using lower difficulty shares, then the minimum share difficulty would increase.
