Bitcoin (BTC) is the first decentralized cryptocurrency and payment system, founded in 2009 and using blockchain technology. Bitcoin, invented by one (or possibly a group of programmers) under the name of Satoshi Nakamoto on October 31, 2008, was introduced to a cryptography mailing list and released as open source software in 2009. Bitcoin is known to be decentralized, censorship-resistant, secure, and borderless. It provides users with the ability to send and receive digital money (BTC) through a peer-to-peer immutable network.
There have been various claims and speculations regarding Nakamoto's identity, none of which have been confirmed. The system is peer-to-peer and transactions occur between users directly, without an intermediary. These transactions are verified by network nodes and recorded on a public ledger called the blockchain, which uses Bitcoin as the unit of account.
