OK so that is what happens to block 18290. It looks like you were mining only first 3 minutes of that block. So this is normal. But I don't get it why you got double from block 18291 since you didn't increase hashes... Did you change anything? The only thing I can think of that could be is a difficulty error in a score system and you change it from 2 to 1. But I guess someone would report that already... Looks really strange...

I haven't changed anything. so it's kind of confusing. Also, I'm on difficulty 6

Losing most of my reward for a short disconnect seems to be very unfair in my opinion. I would really appreciate if slush would explain what happened.

This is the way the scoring method works in order to prevent pool hopping. As the round goes on, shares from earlier in the round have less and less value until they are worth absolutely nothing, so if you only work for the beginning of the round and then disconnect, it is possible to get 0 reward even though you have submitted shares.

This is not a little unfair?
Why is bad when the worker recvive the reward what they shared has? I mean the block value is 25 BTC and we have total X shares, and when u have Y shared then u become this reward. ((25/X)*Y)
Why is that bad?
Please anyone explain me the score based pay system, i dont understand why is that good for all?!

Hi, sure i'am using slush pool.  

I have an Radeon 5870 card using with Phoenix 2.0 client, so this client is not stratum compatible, but no prob, as described on slush internet site, i can use proxy miner.

Proxy Miner ist accepting shares..but in my account settings on http://mining.bitcoin.cz/  there is still the warning message about deprecated protocol and in list of worker -> stratum -> no


What's wrong ?


EDIT: STATS updated for STRATUM... working fine now 

[shad]

is there a problem with the worker stats?
i am submitting my share over mining_proxy --tor
i submitted last share 15minutes ago
workerstats says >14hours

I'm not sure what's happening with your proxy, but you might want to try cgminer or bfgminer instead (then you don't need to run a proxy).

Here's a quick guide for bfgminer and cgminer: http://www.reddit.com/r/BitcoinMining/comments/1cfk7y/beginners_guide_dont_use_guiminer_please_upvote/

If that's too complex, I've heard good things about the bitminter web-based mining software.

It takes sometime (or next round) for that info to get updated on the webpage, don't worry

Because it has been mathematically proven that to improve personal gain (in cost of everyone else in the pool), you should hop into another pool when pool's CDF is around 43.5%
This is why theres this score system (also pplns, dgm, etc...)

you can read more from: http://bitcoin.atspace.com/poolcheating.pdf

It means that with optimal strategy it is possible to
gain on average 28% of ones hashrate by switching from the pool after 43.5%
of the current difficulty number of shares have been contributed.

[desired_username]

That is completely understandable, but I think it's not balanced or well designed if 10 minutes downtime due to connection problem causes 50+% loss on the actual rewards.  :O

Thank you for the PDF, but this is for me mathematically too high
For example:
The round duration is 1:00:00 and the CDF is 50%, i have 500 share soon. When i disconnect from the pool, and the pool work continue, then my shares value would every time less.
with 30% CDF (10k total shares) i earn (with simple method) 0,00125BTC. But we dont have now a block. The pool work continue for half hour. Then the CDF is 45% and the total shares is 15k, then my shares value is now only 0.000833. While the duration would more and more, my shares would every time less.
Sorry for my bad English, its possible that i write wrong many thing, i write here with numbers:

#1
Block Duration: 1:00:00
CDF: 30%
Total Shares: 10'000'000
My shares: 500
My estimated reward: 0.00125BTC

#2
I disconnect at this time with 500 shares.

#3
Block Duration: 1:30:00
CDF: 45%
Total Shares: 15'000'000
My shares: 500
My estimated reward: 0.000833BTC

#4
Block Duration: 2:00:00
CDF: 55%
Total Shares: 20'000'000
My shares: 500
My estimated reward: 0.000625BTC

#5
Block found! 25BTC
Block Duration was: 2:30:00
Total Shares was: 25'000'000
My Shares was: 500
My reward is: 0.0005BTC

Why is that method bad? I become the reward what i worked for the block^^

And what its whit these block?
18284    2013-05-30 09:23:24    5:14:27    48529423    764    0.00000027    none    238658    25.41754350    confirmed
I has
         764
-----------------
     48529423
split worked for the block, and im quasi not rewarded    though that i have the whole block duration worked?

[iFA88]

On the http://mining.bitcoin.cz/stats/ Page
For the current block was the:
Total score of current round: 10645738685290.2051

and now alfter 5 min is 1726123.6787

The variable has flipped?

[bspurloc]

Something went crazy for me overnight (PST), reported hash rate is still the same but all rewards halved.  Switching to stratum2 from stratum3.

so you changed your miner from pointing from
Name:    stratum2.bitcoin.cz
Addresses:  54.215.3.101
          95.211.52.40
          54.225.117.74

to
Name:    stratum3.bitcoin.cz
Addresses:  54.215.3.101
          95.211.52.40
          54.225.117.74

maybe u should try next
Name:    stratum.bitcoin.cz
Addresses:  95.211.52.40
          54.215.3.101
          54.225.117.74

in other words u changed a name to another name that all point to the same ip's, in your mind u did something when technically nothing was done.

interesting to note Slush knocked off 3+ ip's

Score resets to zero top of every hour for everyone, but shares are not reset -- you don't lose anything.  Score has to reset because on long blocks, the number could get big enough to overflow the registers and peeps would start asking about why they were seeing negative scores

[minerapia]

iFA88, yes youre test case is valid if no-one hops the pool....
BUT, lets say theres pool B with exactly the same hashrate ---->

#1 Block Duration: 1:00:00 CDF: 30%
Total Shares: 10'000'000 My shares: 500
My estimated reward: 0.00125BTC

#2 I hop to pool B at this time with 500 shares.
->

#3, pool A Block Duration: 2:00:00 CDF: 60%
Total Shares: 20'000'000 My shares: 500
My estimated reward: 0.000625BTC

#3, pool B Block Duration: 1:00:00 CDF: 30%
Total Shares: 10'000'000 My shares: 500
My estimated reward: 0.00125BTC

== Total estimated reward from 2hours = 0.000625BTC + 0.00125BTC = 0,1875BTC.
(vs. mining only with pool A, without disconnects, which case reward is still 0.00125BTC)
and you must understand that if someone gets more than he should its less BTC for the rest.
nb. This example is very simplified

I agree its kinda harsh, I guess slush's variables arent ment for hashing speeds of today.

0.000625BTC + 0.00125BTC = 0,001875 ^^
But its very important, when the block is founded. I think i dont recvive more BTC with these method^^

Yeah, it doesn't seem fair -- had more than a few of them myself -- but how can the server tell if you're having a connection problem or if you've hopped?  How long does it take for the average mining operation to notice and correct a dc, and how could you account for changes in the chain?  Taking your case as an example, ten minutes is the average block time, so most likely a new block would start before reconnection, maybe even a new round -- where would you want to apply the shares you've started generating again -- the previous round or the current round?

U mean that on 59:59 time i have 500000 score and the total score is 400billion, and after 1:00:00 i would have 0 score and the total score would are 0?
Then why can calculate from this?
U work me for 100$/h job, but every hour i reset your work time to 0min and the end of day i pay you out with cents?

having issues connecting.  Tried the built in url on guiminer, and I also tried stratum2.bitcoin.cz:3333 and stratum3.bitcoin.cz:3333 to no avail. Connection is just not happening, something about IO errors
