All Rights Reserved. The calculations are based on a Proof of Work POW , or the proof that a minimum amount of energy was spent to get a correct answer. A "share" is awarded to members of the mining pool who present a valid proof of work that their miner solved. This cap raises an argument that Bitcoin could have problems scaling. Such a process is easier to produce than a genuinely random one, and has the benefit that it can be used again and again to produce exactly the same numbers - useful for testing and fixing software.
