What is Bitcoin Cash?
Bitcoin Cash is an alternative token that may come into existence as a result of a planned UAHF as mentioned above. Essentially this means that the Bitcoin blockchain may split into two competing chains.
The original plan for a UAHF came about from a contingency plan, proposed by Bitcoin mining company, Bitmain, who were opposed to the UASF for SegWit.
Bitcoin Cash will differ from Bitcoin in terms of the following:
SegWit: Bitcoin Cash will not implement SegWit
Blocksize: Immediate increase from 1MB to 8MB
Coexistence: Replay and wipe out protections ensures that should the two chains continue to compete, Bitcoin Cash aims to reduce user disruption and allows for the safe existence of two chains.
The Community Reaction
MINER -Bitmain, have said they will continue to support SegWit2x and the original Bitcoin chain, and do not rule out supporting the Bitcoin Cash chain as well.
Exchanges- Some major exchanges such as Coinbase, Coinfloor and Bitstamp are not signalling any strong support for Bitcoin Cash and have left the crediting of the forked coins to their discretion.
