This coin is a fork of the Bitcoin network. The prerequisites for its occurrence was a disagreement between members of the Bitcoin community on two indicators - the size of the block and the duration of the recalculation of the network complexity. The main opponents of the current Bitcoin network are the well-known cryptoenthusiast Roger Ver and the large mining pool Bitmain. As a result, they decided to create their own version of Bitcoin - Bitcoin Cash.At that, only two parameters changed: the block size increased from 1 Mb to 8 Mb, the recalculation time decreased from 2016 blocks to 6. The rest of the Bitcoin protocol remained unchanged, including the number of extracted Bitcoins, total emission, SHA-56 algorithm, block time and a mining reward system.Later, on November 15, Bitcoin Cash itself was divided into 2 chains - Bitcoin ABC and Bitcoin SV, where the first is the successor to the ideas of Bitcoin Cash.
