Unlike Bitcoin, it does not use Segregated Witness (SegWit) as a soft fork. Protocol upgrades in Bitcoin Cash are mostly done through hard forks while keeping Bitcoin’s original economic rules intact. BCH was launched on August 1, 2017, as an upgraded version of Bitcoin Core.
The main upgrade was increasing the block size from 1MB to 8MB. This allows miners to process up to 8 times more transactions per second compared to Bitcoin, making transactions faster, cheaper, and smoother for users.
Why Bitcoin Cash Was Created
Bitcoin Cash was created to restore the original qualities of money that Bitcoin was meant to have. Over time, Bitcoin Core became less usable as a currency due to high fees and slow transaction times caused by the 1MB block size limit.
Bitcoin Cash solves these scaling issues by increasing the block size to 8MB. Essentially, it is a community-driven upgrade (hard fork) of Bitcoin that allows more transactions per block.
On November 16, 2018, a “hash war” led to another split, creating Bitcoin SV and Bitcoin ABC.
