Bitcoin Cash (BCH) is a digital currency that is a fork of Bitcoin. As Bitcoin Cash is a result of a chain split from Bitcoin, it shares much of Bitcoin’s fundamentals. In fact, they even share the same history. Due to it being a fork of bitcoin, all on-chain data prior to the split are inherited.
Like Bitcoin, BCH is a peer-to-peer electronic cash system, using the same SHA-256d-based Proof-of-Work consensus mechanism as Bitcoin. BCH also has a target block time of 10 minutes, and its total supply is capped at 21 million.
On November 16th 2018, the Bitcoin Cash blockchain withstood another hard-fork, which resulted in a chain split into Bitcoin Cash SV and Bitcoin Cash ABC. Since then, Bitcoin Cash ABC has commonly used the BCH ticker and referred to as Bitcoin Cash.
