Instead it is underpinned with a peer-to-peer computer network made up of its users machines, akin to the networks that underpin BitTorrent, a file-sharing system, 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 the Bitcoin system were put up so that it becomes progressively more difficult to mine Bitcoins as time passes, and the total number that can ever be mined is limited to around 21 million.
