What is Bitcoin Core?
Bitcoin core is a free and open-source software project that was launched in 2009 by Satoshi Nakamoto, the anonymous creator of bitcoin. Bitcoin core implements the consensus rules of the bitcoin protocol, which define how nodes communicate, validate, and update the shared ledger of transactions, known as the blockchain. Bitcoin core also provides a graphical user interface (GUI) that allows users to interact with the software, such as creating a wallet, sending and receiving transactions, configuring settings, and more.
Bitcoin core is not the only software that can run a full node, but it is the most widely used and trusted one. By running bitcoin core, you can contribute to the decentralization and security of the network, as well as enjoy the benefits of using your own node, such as verifying your own transactions, choosing your own fees, filtering spam, avoiding censorship, and more.
