Bitcoin is a payment and cryptocurrency system invented by an unknown programmer, or group of unknown programmers, by the name of Satoshi Nakamoto. Bitcoin was introduced on October 31st 2008 to a crypto mailing list, and released as open-source software in 2009.
Transactions take place between users directly, and the system is peer-to-peer without an intermediary. Transactions are verified by network nodes and recorded in a public ledger called the blockchain, which uses bitcoin as unit. Because the system works without a central administrator, the U.S. Treasury currently categorizes bitcoin as a decentralized virtual currency.
