[REQUEST] TO ALL POOL OPS

[ShadesOfMarble]

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...)

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 ) Sunday.

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

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.

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.

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

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

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.

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.

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?

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

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).
