Title: Difficulty, What is it? Post by: MoonShadow on October 08, 2010, 07:20:57 PM Can someone explain the difficulty to me? Is it a linear or log unit? I know that there is a minimum difficulty of 1, but what does a difficulty of "1" even mean? Is there a maximum difficulty?

I know that there is a minimum difficulty of 1, but what does a difficulty of "1" even mean? Is there a maximum difficulty? According to the code, difficulty = minimum_best_target / current_best_target bitcoin miners' proof of work is searching for a hash whose numeric value is below the current target.

It takes the same power DIFFICULTY times longer to generate a block on average than when difficulty was at 1. Title: Re: Difficulty, What is it? Post by: eurekafag on October 09, 2010, 09:48:46 AM The easiest explanation: if you multiply the current difficulty by 2^32, you'll get the average number of hashes the network should solve to generate a valid block. If you divide this number by your hash speed you'll get the time required to generate a block by yourself.
