Bitcoin Cash (BCH/BCC) is a hard fork of the bitcoin. This took place in August 1, 2017. A blockchain fork is what occurs when a blockchain splits into two parts. It took over the transaction history of bitcoin on that day, but all further transactions were different. From 30 August 2017 approximately 1,500 more blocks were mined on the Bitcoin Cash chain than on the original one as the high profitability periods attracted a big amount of miners proportional to the previous total processing power. The algorithm has been changed with a new hard adjustment algorithm that hopes to stop serious fluctuations in difficulty while still allowing Bitcoin Cash to adjust to hashrate changes quicker than incumbent bitcoin.
