Bitcoin Core is a software program created to maintain and support the decentralized nature of Bitcoin, which is currently the most prominent and widely used digital currency in the world. The main purpose of Bitcoin Core is to verify whether transactions on the Bitcoin network are legitimate or not. It does this by looking at various blockchains and deciding which one is the most trustworthy. People who use Bitcoin Core will only accept transactions that appear on the blockchain that the software has selected. This helps to ensure that everyone on the Bitcoin network agrees on which blockchain is the "official" one to use.
