An electronic money made in 2009 by Satoshi Nakamoto. The name is also associated with the open source software that he designed, and also uses a peer-to-peer network without centralized storage or a single administrator where the US Treasury calls the bitcoins of a decentralized currency. Unlike most currencies, bitcoin does not depend on trusting major publishers. Bitcoin uses a database that is distributed and spreads to the nodes of a P2P network to a transaction journal, and uses cryptography to provide basic security functions, such as ensuring that bitcoins can only be spent by people owning them, and never be done more from one time.The design of Bitcoin allows for anonymous ownership and transfer of wealth. Bitcoin - bitcoin can be stored on a personal computer in a wallet file format or stored by a third party wallet service, and apart from all that bitcoin can be sent over the internet to anyone with a Bitcoin address. The peer-to-peer bitcoin topology and the lack of a single administration make it impossible for any governmental authority to manipulate the value of bitcoin - bitcoin or cause inflation by producing more bitcoin. Bitcoin is one of the first implementations of the so-called cryptocurrency, first described by Wei Dai in 1998 in the cypherpunks mailing list.
