Bitcoin Cash is a fork of the original Bitcoin Blockchain. It operates with a number of changes that make it faster and better able to scale when compared to its older brother.

It does this by introducing a block size of 8mb, up from Bitcoin Classic’s 1mb. This increase in size allows more transactions to be entered into each individual block before they’re encrypted into the blockchain. This allows more transactions to be processed at once, and so vastly increases the speed of the entire process - allowing transactions and currency to move and be confirmed faster.

This allows Bitcoin Cash to retain the security and utility of the Bitcoin blockchain, while having the ability to deal with transaction volumes close to that experienced by Paypal or Visa.
