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. The larger block size of Bitcoin Cash is intended to handle more transactions per second and aims to maintain lower fees.
