Slush is some thing wrong with the server?

Active workers (at least one share in last hour) = 0

Slush the server seems fine now. And yay us for solving block 113846.
Anyway I noticed that 113846 seems to be the last block reflected in blockexplorer. Does that mean that the blocks generation has stopped? I read some where that the network tries to generate 6 blocks/hr. So have the blocks for the hour maxed out?

Sorry for the rookie question, I am just puzzled and have yet to stumbled across the answer to that question after digging through the web.


Cheers!

A round that has been running for a long time has no better odds of finding a block in the given time period than a new round would.

Which actually is part of my point. You get paid more for the second half of a round shares even though they have exactly the same chance of finding the block. So on law of averages if you only mine the second half of the rounds you will get paid more.

How do you know it when the second half of the round starts you ask? Well you just join rounds that have gone longer than the average length for slush's pool ... so at present difficulty joining rounds at 50 mins in is going to earn more than mining the whole block, no?

No, it won't. Your mistake is to not understand how the randomness of mining works. If you do it your way, your average earnings for the time spent mining will be pretty much exactly the same as if you joined every round from the start. Hint: most rounds will last shorter than average.

It's only minor bug on stats page. Number goes to zero when round is longer than one hour, but there are constantly over 1000 active workers now.

No, there is just some delay before block is shown in blockexplorer. Now you can see all the blocks in BE too.

The point is that nobody knows when the round finish. You'll probably miss many rounds by connecting after the half of expected round duration. You can do this, you'll have +/- same payouts for those blocks, but much less often, so it is not a vulnerability. There are some graphs and analysis done in this thread before. It shows that connecting after some time is not worth of the effort.

Indulge me. How is it that "most" of the rounds will last shorter than the mean?

Aren't half the rounds shorter than the mean and half the rounds longer than the mean? Isn't that what the mean is in a normal distribution?

Yes, but now there are other pools the miner can work on equal shares payment (or solo) when not working on late round shares on your pool, so in aggregate you'll be ahead. It appears to me to be already happening, have you not noticed a surge in hash power in your pool after the mean time has been exceeded for a block?

If you want to see the exact statistics you can try putting any number into the mining calculator. http://www.alloscomp.com/bitcoin/calculator.php. It will show you that the average time to solve blocks is higher than it takes to solve the quickest 50% of the blocks. The problem is that you don't know in advance which blocks will end up within those 50%.

The distribution isn't normal, there is a graph at the pool which shows it: http://mining.bitcoin.cz/stats/graphs/

As you can se, it's kind of open ended. Your suggestion for fooling the pool requires there to be an upper limit to how low it can take to solve a block, and a normal distribution within this range. That's not how it works. In theory there can be a block that will never be solved.

If it's happening, it's the participants in the other pools that are being cheated. They will end up sharing some of the profits for the long blocks, and all of the profits for the short ones. For those who use Slush's pool all the time it will mean that they will get a lower share for the long blocks, but they will also take shorter time to solve, so it averages out.

Hey Slush,

Have you tried my UI improvements greasemonkey script? (http://userscripts.org/scripts/show/98553)

Would you be willing to link to it from mining.bitcoin.cz and/or the top post of this thread? Obviously you would want to say that it is a 3rd-party script which could be changed by me to something evil at any time (not that I would do that).

Another possibility is you could host an approved version of the script, or link to an approved version in the version history on userscripts.org.

I assume that some people on this thread have reviewed the code and can vouch that it is not evil (can anyone back me up on this?).

My script also puts your bitcoin donation address (and mine) at the bottom of the workers page.

I know, no need to poke me here Smiley.

From my investigation the sending part of the payment is definitely not this pool. You probably used the same wallet somewhere else Wink. I checked my bitcoind logs, database logs and blockexplorer details and it is absolutely clear Smiley.

Not yet, but I read the code right now. Looks like a lot of work Smiley. I'll add link to the first post and I'll consider to adopt some info you've tweaked into main GUI. Mainly switch the "last share at" to "last share before", which I consider as really useful. But there are lot of other feature requests, so I cannot promise it to some date Smiley.

I see a bug or problem using ur script on google chrome.
It doesn't save the check boxes. save given by slush has no use.
Every time i closes google chrome completely & open chrome, every thing is back to NO SCRIPT page, then have to change Time offset, & check the check boxes needed again.
Please make it save the changes. I used google chrome 10.0.648.134 version.

Hi dishwara,

I was able to reproduce this problem, and I believe I fixed it. Please install my latest version of the script, then refresh the mining page and then change a setting. From then on, your settings should be saved between browser sessions.

If this script is making your life easier, please consider a donation: 19hMEAaRMbEhfSkeU4GT8mgSuyR4t4M6TH

Thanks!

Hi, I'm sorry if this question is irrelevant or has already been answered (I'm fairly new to Bitcoin and may not understand fully). Anyway, I'm just wondering what happens to the transaction fees earned by the pool. Are these distributed to the workers? Thanks Smiley

Currently they are taken by the pool operator (this is the case in all existing pools currently).

Right now, they are so minuscule that they are insignificant.
