m0mchil: Why'd you remove the retry-on-network-error code when you merged my branch? This greatly improves yield on many pools. Also, why remove GW/Efficiency? Useful data, that! Finally, when will phatk be optional?

I wouldn't mind being added to your developer list (Spesmilo & some patches for the Satoshi client): 1ABvQwiuCnySQqBzruaAcdrkgYae9LoqWz

Disclosure: I also operate competing pool Eligius

Eligius is PPS-like (SMPPS) with almost no fee (it works out to less than 0.0001%). We've been having some trouble lately, and stats will probably be down for at least another 16 hours, but it's a good choice when it's working.

I had a family emergency and was away from home on Thursday; didn't have access to the server passwords. Got it sent out Friday morning, then 3 crashed hard. Finally got 3 back online tonight, so it should process as soon as it finds a block.

Please be sure to do this right, using integer satoshi units, not some high-level units like BTC.

Might make sense to support the already existing bitcoin: URI standard encoded in QR-Codes.

This probably means there's a transparent proxy interfering. Try disabling LP.

He submitted 0.4 BTC worth of shares, so he gets paid 0.4 BTC. Simple. Your percent is an arbitrary number, with no relevance to the work done.

I propose that miners which support this extension send a "X-Mining-Extensions: noncemask" header when requesting work. If the server supports the extension, it should respond with the same header. For other extensions, "X-Mining-Extensions" should be a space-delimited list of elements which can have parameters after an "=" character.

When this extension is active, the server should send an additional field in the JSON-RPC reply: "noncemask" is a hexadecimal-encoded mask of the nonce bits a miner is allowed to change in the header.

For example, if the server sends then the miner should change only the last 29 bits of the nonce.

This allows the server to give the same work to multiple miners with different nonce ranges for each to scan. Combined with X-Roll-Ntime, this can greatly improve efficiency of the work-generating component.

In addition, miners may send a "X-Mining-Hashrate" header set to their average hashrate (in hashes per second) which the upstream server might use to choose a proper sized noncemask.

Thoughts?

Edit: noncemask has been superceded by noncerange

Yep, it's phatk. If I add a swapfile, it will start (slowly). So phatk demands more system RAM for... a whole 1 MH/s improvement. Please offer the original kernel (with the recent patch) again!

Currently 0.00003625 BTC per share. I think Artefact2 decided against it because it isn't completely guaranteed. I suggested he show the price-per-share in the block list though.

Please use type 2 from https://forum.bitcoin.org/index.php?topic=19137.0 so we can have secure services!

Your first flaw is in assuming there's something inherently fair about the Proportional method. This usually comes from the misconception that people can make progress mining. The fact is that over 99.99% of shares are completely worthless and do absolutely nothing for the pool. They have no relevance whatsoever to the block that might (or might not) be found at the end of the round. Only 1 share finds that block, by itself, with no help from the other shares.

The goal of pools is to pay miners for lower-difficulty fake "blocks", while collecting the rewards itself from the real blocks. This reduces variation for the miners. Proportional is simple, but by far not the only way pools might decide to pay miners. The most fair method, with least variation, is to pay them 1/difficulty for each difficulty 1 share: this is called Pay Per Share. In comparison, Proportional pays miners more than their fair (PPS) reward when it finds a block quickly, and less when it takes a long time to find a block. Because of this uneven distribution, it is most effective to implement "pool hopping" to mine on the pool currently offering the highest reward per share (ie, the one with the fewest shares in the current round).

Straight PPS was originally implemented by OneFixt2 for BitPenny, and is a popular option at Deepbit despite their 10% fees. However, it is more vulnerable to true cheating, and when this happens, the pool operator takes the infinite hit from it.

Eligius has (after much notice and even poll from members) switched to a system almost like PPS. Miners are generally paid the full 1/difficulty reward for each share (without the huge 10% fees historically associated with PPS), but the system keeps track of what the pool has itself earned overall, and limits payouts to ensure the operator does not take a hit when there is cheating or extreme unluckiness going on. At the same time, it tracks what miners would have earned under straight PPS, and if someone was ever underpaid (due to not having the funds available) will pay them a bonus later if it has extra funds (from lucky/short blocks).

All the payout systems will eventually tend toward the same total payout over time, with one exception: due to the proportional method's predictable unfairness pattern, miners can achieve 30% greater earnings than their work's fair pay. Those who do not implement pool hopping, see an effective 30% loss over time. This is the primary motivation for avoiding the proportional system.

Quit trolling. BTCGuild would probably pay about the same over time (though you'd get higher variance because it's proportional), Deepbit of course would pay 10% less because of the fee.

It isn't less. That's your brain failing. Again, quit trolling. Proportional always underpays on long blocks, and always overpays on short blocks (which is why it has a problem with pool hoppers).

You got paid the proportional reward for the work you did in full. Stop slandering our pool. I'm surprised you haven't been banned from the forums yet.

Minimum payout is now 0.33554432 BTC (200 TBC).

Despite what Artefact2's stats page says, our last block is valid (and has 2 confirmations as of the time of writing this). It included, in addition to the usual Eligius-3 payouts, also the sendmany for all the US balances. This means that if you had a US balance remaining, it should now be paid in full. Please report if there seems to be any problem with it. If I don't hear any problems with the US payouts, I will plan to do the same for EU balances on Thursday.

US balances have been paid in full via a standard sendmany transaction (txid: 451718e781fe39e6014d0000f891659d571eff25995e943b864a641b412dcd62). Since I didn't pay a fee, the network won't relay it, and you won't see it until it's confirmed, which should be no later than Eligius-3's next block. Assuming no problems, I plan to do the same for Europe's balances.

It doesn't work:
You forgot mine.

This is probably the problem. Phoenix with phatk also Killed-crashes.

What does this actually do?

It means pool hoppers are welcome to hop into (or out of) the pool at any time. They will not be punished for doing so-- nor will they be paid more than the fair earnings for the work they do.
