Definition of Bitcoin Cash
The definition of the official Bitcoin Cash website says:
Bitcoin Cash is a peer-to-peer electronic cash for the Internet. Fully decentralized, does not involve (the role of) the central bank and does not require a third party to operate.
The emphasis on the "peer-to-peer electronic cash" section is done because the main benefits of Bitcoin Cash are solely focused on the ability to carry out more transactions that are free of network delay constraints. Bitcoin Cash does offer a way to adjust the difficulty level of work faster than the normal difficulty adjustment interval on Bitcoin.
