On 18339 i have stopped the mining on half time, and my previous shares value is 0 ?!
On 18331 i have mined the whole block, but with only one worker.

Thats fair?

Yes, its fair. You completly stopped looking for the block solution, youre shares would be worthless anyway if someone else would not have finished the job you left halfway.

The purpose, and a feature of this pool to to discourage people from casually coming and going in the middle of a block. If you feel this is unfair, you are in the wrong pool.

Slush has been pretty good at refunding these - usually he attaches the value to another block.

[el_rlee]

payout for 18339 is too high for me (~20% too high)

it has seemingly been attached to block 239282 as my reward is exactly double on that block.

Not me i got screwed lol

my rigs can't connect to api2.bitcoin.cz:8332, anyone else having the same issue?

If you have Stratum compatible software (miner) use: stratum.bitcoin.cz:3333

not here, i got a smaller than usual reward and it shows only 25 Btc reward, not double.

Only for interesting!
When i join only on 1:00:00 to the block and work until the block is founded, example 2:00:00 then i become better reward as i the whole block worked has? (Sorry for grammar)

Don't mention it.

iFA88 , this is because of how the system is set up on this pool: each share gives you a score that slowly falls down if no new shares are submitted. In effect, the shares have a set lifetime; when they "die" so does that little part of the score they brought.

To exemplify, let's forget about the score and only consider the share lifetime.
Let's say a block is found in 10 seconds, and you submit 10 shares, each share 1 second apart:

Code:

Time	0s	1s	2s	3s	4s	5s	6s	7s	8s	9s	10s
Shares	1	2	3	4	5	6	7	8	9	10	Block

We're also going to presume each share has a 'lifetime' of 3s. This is how the system works.
So, this means that if you mine for 2 seconds then stop, you would have 3 shares. However, since the block is found at 10s, those 3 shares will look like this:

Code:

Time	0s	1s	2s	3s	4s	5s	6s	7s	8s	9s	10s
Shares	1	2	3	3	2	1	0	0	0	0	Block

(share 0s dies at second 4, share 1s dies at second 5, share 3s dies at second 6)

So at the end of the shift, when the block is found, you do not have any relevant shares, although you have submitted 3 shares.

The opposite case is when you start mining towards the end of a shift:

Code:

Time	0s	1s	2s	3s	4s	5s	6s	7s	8s	9s	10s
Shares	0	0	0	0	0	0	1	2	3	3	Block

At the end of this shift you would have 2 shares (share 6s would die right as the block was found).


P.S. Any chance we could add an explanation like this to the pool FAQ to avoid having this sort of questions every once in a while?

Great example, thank you!
I have one question only, on the 3. example, why die my shares when i work normal?

Yes, you would get better PPS than the guy who worked whole 2hrs (thought same reward from the block if you have similar hash rate). Thing is that you cannot anyhow guess when the block is found, it can be next minute or it could take 10hrs.
TBH, If you consider fair to be paid from every share, maybe PPS or PPLNS would suit your mining preferences better. Slush's pool is all about 24/7 mining. If you come and go randomly, you won't get good results here.

[minerapia]

Because the number of shares alive gives you the score which says how much you get rewarded when the block is found.
Score pretty much is youre average hash rate near the time when block is found.
If you ask "Why?", Slush just happens to think this is best way to prevent people from cheating (because its impossible to guess when the next block is found)

[nottm28]

Anyone one else seeing problems with submitted shares.

All workers are still submitting but none of them are being reflected in the accounts page...

[minerapia]

Yep, webserver/database not updating (started around 2013-06-03 10:40:00 UTC). Stratums seems to be ok, so no worries.

I think stratum is having problems as well, my last submitted share was 19 minutes ago according to my account page. my score 0.0703 for current round.
