Bitcoin Cash (BCH) vs Sui (SUI)

Bitcoin Cash is a Proof of Work (PoW) blockchain that was born on August 1, 2017, following a hard fork from Bitcoin due to a disagreement within the Bitcoin community. While the majority of the community chose to adopt the SegWit proposal, a dissenting faction decided to split the blockchain (hard fork) and implement their own improvement, namely an increase in block size from 1 MB to 8 MB, following the original vision of Satoshi Nakamoto.

Sui is a layer 1 blockchain designed to host smart contracts and operates on a Delegated Proof of Stake (DPoS) consensus mechanism. Following the failure of Facebook's Diem project, some of the engineers came together to form Mysten Labs. The technology of Sui incorporates some technological innovations from the project, including the Move programming language and a modular and parallel architecture that allows for the simultaneous processing of a very large number of transactions.
