Bitcoin is a digital currency based on an open-source peer-to-peer software protocol that is independent of any central authority. Bitcoin issuance and transactions are carried out collectively by the Bitcoin network. Bitcoin relies on cryptography to secure and validate transactions, and is thus often referred to as a "cryptocurrency".
Bitcoins can be "mined" by users, and also transferred from user to user, directly via computer or smartphone without the need for any intermediary financial institution. Bitcoin transactions are pseudonymous and decentralized. Proponents of Bitcoin argue that it is not susceptible to devaluation by inflation or seigniorage in the way other modern "fiat" currencies are. Nor is it associated with an arbitrary store of value such as gold, unlike hard-money or representative currencies.
The Bitcoin protocol was first described by Satoshi Nakamoto (a pseudonym) in 2008. Each bitcoin is divided into 100 million smaller units called satoshis.
