Bitcoin Core

Bitcoin Core is the reference implementation of the Bitcoin protocol, providing full node functionality and a built‑in wallet. It validates the blockchain, relays transactions, and enforces consensus rules, allowing users to verify the network independently. The integrated wallet enables creation, storage, and management of Bitcoin addresses and private keys, supporting sending and receiving funds directly from the node.

The software is targeted at developers, researchers, and enthusiasts who need a complete, verifiable Bitcoin client, as well as users who prefer to run their own full node for security and privacy. It runs on macOS and other platforms, offering command‑line and graphical interfaces for interacting with the network and managing wallet data.

Bitcoin Core is released as a stable, version‑ed package, with regular updates that address bugs and improve protocol compliance. The release notes document changes such as wallet migration issues and newer protocol features, helping operators keep their nodes up to date while maintaining compatibility with the Bitcoin network.
