Instead it's underpinned by a peer-to-peer computer network composed of its users machines, akin to the networks that underpin BitTorrent, a file-sharing program, and Skype, an audio, video and chat service. Bitcoins are mathematically generated as the computers in this network perform tough number-crunching tasks, a procedure known as Bitcoin mining. The mathematics of this Bitcoin system were put up so that it becomes progressively more challenging to mine Bitcoins over time, and the entire number which can ever be mined is limited to around 21 million.

This mining process gives Bob a score to know whether or not to move with Alices transaction. .
