Bitcoin Cash explained
What is Bitcoin Cash or BCH?
The need to accommodate an increasing count of transactions per second contributed to a push by some in the Bitcoin community to create a hard fork to increase the transaction block size limit. This push came to a head in July 2017 when some members of the bitcoin community including Roger Ver felt that adopting BIP 91 without increasing the block-size limit favored people who wanted to treat bitcoin as a digital investment rather than as a transactional currency. Bitcoin Cash supporters, compared to Bitcoin, were more committed to a medium of exchange function.
In July 2017, the Bitcoin Cash name was proposed. The change, called a fork, took effect on 1 August 2017. As a result, the bitcoin ledger called the blockchain and the cryptocurrency split in two separate networks.
The technical difference between Bitcoin Cash and Bitcoin is that Bitcoin Cash allows larger blocks in its blockchain than Bitcoin, which in theory allows it to process more transactions per second.
Bitcoin Core supporters wanted to keep blocks small so that nodes could be operated with less resources and did not believe that increased computer storage capacities would be able to keep up with the Bitcoin blockchain’s growth.
