₿itcoin is a decentralized digital currency that enables peer-to-peer exchange of value in the digital realm through the use of a decentralized protocol, cryptography, and a mechanism to achieve global consensus on the state of a periodically updated public transaction ledger called a 'blockchain'. It was first described in 2008 in a whitepaper titled ₿itcoin: A Peer-to-Peer Electronic Cash System by Satoshi Nakamoto (see below for Spanish version), whose true identity remains unknown. ₿itcoin is based on proof-of-work and can be bought, sold, and exchanged directly without an intermediary such as a bank. It has risen dramatically in value since its public launch in 2009, with 1 ₿TC currently worth 1 ₿TC.
