Hi,
how can I interpret:
Found blocks
Current shares
Score

at http://mining.bitcoin.cz

I think Found blocks are the valid blocks I found but what are the Current shares? I got 1 after ~2h mining. And how is the score interpreted.

Would be nice to have an FAQ with answers. I am not going to search this whole thread for it.

Found blocks-  YOu found the awnser to the whole block, dude, CONGRATZ

Current shares- valid hashes for a lower difficulty of the block(iffy on why)

Score- Not a clue!

Every hash you do for a pool has one of the three following outcomes. The hashed result is...

1) Smaller than the current difficulty's target == you found a block.
2) Smaller than the lowest possible difficulty's target == you found a share.
3) Larger than the lowest possible difficulty's target == try again.

Holy-Fire explains above what Score means.

That's true. But shares are pretty easy to find. Unless you're mining on a CPU or something, you'll very rarely go through an entire round without finding any share.

For participants which are very small in relation to the pool, the variance is caused by the variance in the number of shares and position they find.

For participants which are not too small in relation to the pool, the variance is caused by the variance in the number of blocks the pool finds.

The mining difficulty went up across the network at 05/09/11 @ 4:17:24pm EST (the same day slush happened to restore the pool). You might have noticed a drop in bitcoins generated because of that. See https://en.bitcoin.it/wiki/Difficulty

I have moved 90% of my miners back to Slush since the outage(I have some CPUs in deepbit atm).  I think he is a stand up guy and is doing his best.  Been in the pool since late March and would love to see a roadmap and expected timeline of features and failure protection.

I appreciate his post-mortum on events and can very well believe an attack could have brought the pool down.  Specifically:

-Any date on long-polling?  Every little bit helps and when I switched to deepbit for the few days it was amazing to see the block change and miner switch.

-Could we maybe implement IP Address reputation?  I am on a dynamic IP address but it rarely changes.  If a worker that has existed for 10 days is connecting maybe it could be considered "Graylisted" and not part of getwork spam?  This may work for the initial attack response to block all traffic from low reputation IP Addresses.  Just like share aging you could do the same for account share/ip reputation.

-As has been mentioned before - any chance you would take on a partner?  Someone who can watch the ship when you are away?  At the least tell people you will be on vacation for a weekend and not actually do it so it cannot be reliably predicted when you will not be present.

I do work as a Network Administrator and feel your pain - I carry a cellphone and cellmodem most places I go to support my employer.  But I am not the only guy who can fix issues if I am unreachable.  I think people will start returning when some of these issues are addressed.  Tycho should not be at or near 50% total hash rate for the good of the system.


Anyhow thanks for all the work you have done, I am happy to pay 2% and I am sure the future for this pool is as good as deepbit.

Those calculations, as I explained, were specifically for the case that the miner is very small. In this case the variance is completely caused by the variance in the number and position of the shares submitted and are not affected at all by the size of the pool. These calculations do not work when the miner is substantial in relation to the pool, for this you need different calculations. The summary is that the greater the percentage of the miner in the pool, the greater the variance, so bigger pool = smaller portion = less variance.

mtgox has an API. You can use https://mtgox.com/code/withdraw.php?name=blah&pass=blah&group1=BTC&btca=bitcoin_address_to_send_to&amount=# to send bitcoins (I haven't used it this way myself). Write a scheduled script on your end that accesses this page every day.

How come everyone seems to move to other pools?
Whats wrong?
