Title: Percentile
Post by: Frizz23 on January 28, 2012, 09:02:13 PM
Two questions:

1) Has anyone ever made some kind of percentile graph of the big pools (like deepbit, etc.) ?

2) Is there a max. time (or better max. number of operations) until a block will be found for sure (100%). Or could it happen that the time to mine one specific, nasty block could be millions of years?

slush has this for his pool here (http://mining.bitcoin.cz/stats/graphs/), I'm sure there are graphs for other pools as well.

2) Is there a max. time (or better max. number of operations) until a block will be found for sure (100%). Or could it happen that the time to mine one specific, nasty block could be millions of years?
There is no such max time. A block could theoretically take millions of years, the probability for that is positive though unbelievably tiny. The probability that a block will take at least N shares is roughly exp(-N/D) (where D is the difficulty).

1) Do you mean which pools have how much percentage of the hashrate?  If so, here: http://blockchain.info/pools

2) What he said.  :)
