BTC Guild: Stratum with variable difficulty. Current SPM target is 15 (10~19 depending on a miner's proximity to a difficulty adjustment).

Thanks eleuthria. I'm interested in the method you use to calculate the SPM target and how it's affected by difficulty changes - is the algorithm posted somewhere?

The full SPM is based on a 5 minute average. If they are 20 SPM or higher, the difficulty is doubled. There are extra adjustments during shorter time intervals to catch extremely fast miners in under 5 minutes. Additionally the difficulty is halved if no shares are submitted after a minute, or if SPM drops to 6 or less (which would only happen if the miner leaves the server/turns off miners behind a proxy).

EMC is GBT and has automatic VARDIFF on all three servers.

US1: 20 SPM over 3 minute target window
US2: 24 SPM over 3 minute target window
US3: 28 SPM over 3 minute target window

P2Pool does local work generation and uses variable difficulty— and thus should be compatible with very high speed mining. It would be a bummer to see this list promote more centralization with the launch of ASIC miners as people look for new pools that can keep up.

Thanks for your input, gmaxwell. I think that's an important point about p2Pool. The reason for the extra columns in the list is to make it more obvious which pools are ASIC ready and which are not. I'll work on renaming headings so that p2Pool won't be left out.

I agree that it would be best to ensure the new list prefer decentralized pools (GBT and p2p) over centralized ones (Stratum).

Eligius should be ASIC-ready as soon as we switch to the new CPPSRB reward system, hopefully before November.
I plan to use a target of 20-30 shares per minute, but might make it miner-configurable.

Thanks Luke-Jr. I'll list Eligius as "TBA" under vardiff.

As far as list preferences goes, the list is completely agnostic - I want to provide objective and verifiable information about the pools and let miners make up their own minds about which is preferable.

The *new* list should provide objective information. The preference should be left to the user.

UPDATE:

I'm in the middle of adding columns for Variable difficulty and Stratum/GBT to the Mining pools list. I'm a bit short on time this week, so I be ever so grateful if you could post whether or not you currently offer variable difficulty and if so whether it's User defined or a target of shares per minute (including the target number). Also please indicate whether you use Stratum or GBT or neither.

I know many of you plan on offering Variable difficulty shares and Stratum or GBT in the near future and if you post here when you do offer these options I'll be able to include it in the Mining pools list sooner

planning to have stratum with vardiff by 1st November

Great! What sort of vardiff are you planning on?

a target of shares per minute - details to come

Pay Tx reward? Depends, we're "reusing" them for our Wallet-service, but we're not crediting users for the TX-fees.
Pay stales? No, we don't. Unless you count orphan blocks (and their shares)

Thanks Jine, I must have misunderstood some posts in your thread. I'll fix it up before (or more likely on Sad

) Sunday.

But why should we worry about that?

No need to. There are even people still mining on prop pools - it's their decision, I don't care. (I guess the same persons keep >100 BTC on their pool accounts...)

I think no one keeps more than ~5 BTC on his pool account

But really, there are many users who keeps more than 100 BTC on his pool account. May be this wrong, but they don't care.

Quote from: ShadesOfMarble on September 11, 2012, 05:30:59 AM

And that's why I would never mine on a SMPPS pool [with negative buffer].

You are free man, so you can do whatever you want, even if you want compare incomparable things. But why should we worry about that?

P.S. I can think that I'm Julius Caesar. Cheesy

But have done work you never get paid for. Of course, no one promised you that you WILL get paid because everyone should know that's possible with SMPPS + large negative buffer.

BUT

What's more painful? A PPS pool shutting down and losing some balance (I think no one keeps more than ~5 BTC on his pool account, at least I do) OR a SMPPS pool shutting down with negative buffer and losing everything you had in your buffer (which was as much as 30 BTC for some people on arsbitcoin IIRC)

OF COURSE the SMPPS pool op isn't "scamming" anyone when closing the pool and not paying out the buffer. But in the end miners can lose WAY more on SMPPS pool compared to a PPS pool. And I think more miners care about *that* fact instead of who is technically right...

And that's why I would never mine on a SMPPS pool [with negative buffer].

*SMPPS are not hoppable at all.
*SMPPS has zero maturity time
*SMPPS has lower instability than PPS (which should be the most unstable)

Why didn't you bother to read the definition of the terms?

I did.

Quote from: Meni Rosenfeld on September 11, 2012, 04:19:02 AM

"Maturity time" means the time until the reward is received. If an SMPPS pool has a very negative buffer, it will take a long time for miners to get the reward for current mining.

That's not the definition used in the table.

Quote from: Meni Rosenfeld on September 11, 2012, 04:19:02 AM

"Instability" includes the severity of a collapse. If a PPS pool collapses nothing happens. If an SMPPS pool collapses miners can lose a lot of money.

No, if a PPS pool collapses, miners lose their due balances. If a SMPPS pool collapses, nothing happens, and nobody is out any money due.
