Sui
A Move-based Layer-1 from former Meta engineers, optimized for parallel object-oriented execution and sub-second finality. Launched mainnet in May 2023.
Sui is a Layer-1 built by Mysten Labs (former Meta / Diem engineers). The execution model treats every on-chain entity as a typed object owned by an address or shared, which lets the protocol detect independent transactions and run them in parallel without locks.
Contracts are written in Sui Move — a customized version of the Move language originally designed at Diem. Consensus combines a fast path for owned-object transactions (no consensus needed) with a BFT protocol (Mysticeti) for shared-object transactions.
