And what that property entails is that if you take the challenge numbers, android games for bitcoins who does coinbase give my bank account info to you take these proof numbers, and you concatenate them together, and you make them the input to a cryptographic hash function, the resulting output has to have a large prefix of zeroes And that doesn't have to be all zeroes, but a large portion of the beginning-- the prefix-- has to be all zeroes And if you think about for a moment, given that cryptographic hash functions, given that their output tends to look fairly random, it's unlikely in any given instance that you are going to see a proof. Bitcoin miners shutting down world wide! What are the advantages of Bitcoin?
