Bitcoin Core

Bitcoin Core is the principal software implementation that facilitates user interactions with the Bitcoin blockchain. Originally created by Satoshi Nakamoto, Bitcoin Core is not controlled by any singular entity, corporation, or organization. Instead, it receives ongoing updates, maintenance, and scrutiny from a worldwide community of software engineers and computer scientists. By running the Bitcoin Core code, users can function as network nodes, autonomously verifying the legitimacy of block creation and transactions conducted by other network participants.
