Unlike traditional currencies, that are issued by central banks, Bitcoin has no central monetary authority. Instead it is underpinned with a peer-to-peer computer network made up of its own 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 difficult number-crunching tasks, a process known as Bitcoin mining.  The math of the Bitcoin system were set up so that it gets progressively more difficult to mine Bitcoins as time passes, and the entire number that can ever be mined is limited to around 21 million.
