BCH is a hard fork of Bitcoin. It modifies the Bitcoin code to support large blocks and does not include Segwit. In order to solve the problem of Bitcoin expansion, BCH introduces an emergence mechanism to truly solve the consensus problem of Bitcoin itself, and adds thin blocks to accelerate synchronization. (Because there are two chains of BCHABC and BCHSV after the end of the BCH fork, MyToken keeps pace with most exchanges in the market, denoting BCHABC as BCH, and BCHSV as BCHSV.)
