Bitcoin is the first cryptocurrency. It has an open source that no one owns or controls. Its transactions and emissions are regulated by an extensive peer-to-peer network. The cryptocurrency uses a single database distributed on the network, included in a decentralized peer-to-peer network that uses an electronic digital signature and is supported by a proof-of-work protocol to ensure the security and legitimacy of the funds put into circulation.
