Bitcoin Cash ABC is a direct offshoot of the Bitcoin network. It was created when part of the original community did not agree on the block size being generated on the network. Therefore, Bitcoin Cash was launched, with one major adjustment, the size of each block was increased from 32MB to 128MB, allowing for far more transactions to be processed at a time. In 2018, when the community split again, Bitcoin Cash ABC was created as a successor of the original Bitcoin Cash.
