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.
