In this manner, all users are aware of every transaction, which prevents stealing and double-spending, where someone spends the same currency twice.

Unlike traditional currencies, that can be issued by central banks, Bitcoin has no central monetary authority. Instead it's underpinned by a peer reviewed 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 service. Bitcoins are mathematically generated as 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 gets increasingly more difficult to mine Bitcoins as time passes, and the total number that can ever be mined is limited to around 21 million.

To see how the system works, imagine someone called Alice whos trying out Bitcoins. Reduce sign up for a cryptocurrency wallet to place her bitcoins in.

Complete client This is similar to a standalone email server that handles all aspects of the process without relying on third-party servers. Alice will control her whole transaction from beginning to end . Understandably, this is not for beginners.

Mining, or processing, keep the Bitcoin process secure by chronologically adding new transactions (or blocks) to the chain and keeping them in the queue. Blocks are chopped off as every transaction is finalized, codes deciphered, and bitcoins passed or exchanged.
