Bitcoin Cash (BCH) is a decentralized cryptocurrency that operates on a peer-to-peer electronic cash system. It was "forked" from Bitcoin (BTC), the world's largest cryptocurrency, in 2017 due to a division over the protocol's future. A fork happens whenever a community makes a change to the blockchain's protocol or basic set of rules, which results in a new blockchain. In the case of Bitcoin Cash, the community set out to create a cryptocurrency that's better suited than Bitcoin for cheap, every day payments. Bitcoin itself, despite originally being named "Peer-to-Peer Electronic Cash" in its whitepaper published in 2009, may not be well-suited for use as cash in everyday purchases due to its fees. Bitcoin Cash aims to scale to accommodate global payment system demands, with a block size of 32MB as of 2023, compared to Bitcoin's 1MB block size.
