What is Bitcoin Core?
Bitcoin Core is the reference implementation of the Bitcoin protocol, providing software that connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It includes a wallet for managing Bitcoin and an optional graphical user interface, serving as a full node that upholds network security and decentralization.
Developers, researchers, and users who want to run a fully validating Bitcoin node to support the network, verify transactions independently, or interact programmatically with the blockchain.
It is the most trusted and widely used Bitcoin client, offering unparalleled security, direct participation in consensus, and a commitment to open-source, decentralized principles without relying on third-party services.
