Instead it's underpinned by a peer-to-peer computer network made up of its own users machines, akin to the networks which underpin BitTorrent, a file-sharing program, and Skype, an audio, video and chat services. Bitcoins are mathematically generated since the computers in this network execute difficult number-crunching tasks, a process known as Bitcoin mining.  The math of this Bitcoin system were put up so that it gets progressively more difficult to mine Bitcoins over time, and the total number which can ever be mined is limited to around 21 million.
