I notice that the "verified" shares take a long time to completely finish loading. What is the main limitation that makes it take so long? Is it strictly bandwidth between peers, or is it CPU based verification that is slow, or perhaps it is a disk throughput issue like bitcoind when it loads the blockchain for the first time?

This is normal and doesn't hurt you. It's because any given share requires the previous 24 hours of shares to be validated, so you can't validate them all in one go. You have to download the last two day's shares, validate the last day's, then wait a day for those unvalidated ones to be forgotten about, all the while new, instantly validated ones are arriving.

Right, I was just wondering what the specific bottleneck is when the verification is taking place.

I'm sure this has been answered before ... but ...
Is there somewhere where you can see the pool (share-chain) if you are not running p2pool at the moment?
i.e. blocks + shares + share difficulty, also current block being worked on and unpaid share list?
I guess forrest's client is the best one to consider if I'm not running p2pool if that info is available?
( Where this comes from: http://forre.st:9332/graphs/ )

This one seems to not work any more:
http://yat.uukgoblin.net/p2pool-stats/current_payouts.html

(or is this information lost for eternity? Thus no way to verify anything?)

I plan to make something like the Bitcoin Block Explorer for shares, but even then, old shares are cleared out after they're 48 hours old, as they're unnecessary. The current block payout is determined by at most the last 24 hours of shares.

Wait, the same block was just found again!

Sometimes peers broadcast old blocks, for example if they are syncing up with the P2Pool sharechain. It's fixed in newer versions of P2Pool, sorry for the confusion.

forrestv,

ok, thanks for the explanation, I'm going to update my p2pool copy ASAP.

Thanks kjj,

your link points to a different block, mine is this:

Code:

2012-02-09 12:34:11.499075 GOT BLOCK FROM PEER! Passing to bitcoind! 929038fc bitcoin: 27aafb3b399eb60be707ceb402259cd4b018c91b4ff41ac5a9

And block explorer says it was found two days ago.

So who is wrong? Blockexplorer or p2pool log file?

no news about 12:34 one? Where did it go?

Quick look at block explorer shows blocks 166020 & 166021 found araound that time. Both blocks have generation going to 1KUCp7YP5FP8ViRxhfszSUJCTAajK6viGy (This address has _generated_ about 93,000 btc).

Just a guess, really only a guess, but 2 blocks found by a big pool orphaned the p2pool block. Cry

Shares are swinging a lot as well

Code:

2012-02-09 13:22:09.138339  P2Pool: 18384 shares in chain (17438 verified/18439 total) Peers: 43 (33 incoming)
2012-02-09 13:22:16.634768  P2Pool: 17308 shares in chain (17314 verified/17314 total) Peers: 43 (33 incoming)
2012-02-09 13:22:19.669540  P2Pool: 17309 shares in chain (17315 verified/17315 total) Peers: 43 (33 incoming)

is this "correct"? I've never looked at share numbers a lot, to be honest.

Six here

It depends on your time-zone.

I think we should define what is a "mining day" more precisely, like: from 00:00 to 23:59 GMT or something like that.

Btw, my six shares are enough to cover just a couple of days of bad luck.

Regards.

spiccioli

It wouldn't really matter would it? Either someone sees that we find 8 blocks one day and 0 the next, or someone sees that we find 4 blocks one day and 4 blocks the next. Either way it's 8 blocks in a 48 hours period.
