Bitcoin Cash (BCH) is a cryptocurrency that was created in 2017 as a result of a hard fork of the Bitcoin blockchain. The hard fork was a response to concerns about the scalability and transaction processing times of the original Bitcoin blockchain. Bitcoin Cash operates similarly to Bitcoin, allowing for peer-to-peer transactions and the creation of new tokens through a process called mining. However, there are some key differences between the two, including block size and transaction processing times. Bitcoin Cash has a larger block size, which allows for faster and cheaper transactions compared to Bitcoin.
