Sui is an object-centric Layer 1 that runs smart contracts in Move and executes independent transactions in parallel. Consensus is delegated proof of stake with Mysticeti v2, a DAG-based BFT protocol. Transactions that touch only owned objects, such as simple transfers, take a fast path and finalize without going through consensus. Mysten Labs measured full-node latency at about 0.40 seconds in Europe and 0.65 seconds in Asia after the v2 rollout. Fees are paid in SUI.
Much of what other chains leave to third parties comes from Sui and Mysten Labs directly. zkLogin and passkeys give users web-style sign-in, Seal handles encryption and access control, Walrus stores large files, and Nautilus runs verifiable off-chain compute. Programmable Transaction Blocks chain up to 1,024 operations into one atomic transaction. GetBlock serves Sui over gRPC, with Shared endpoints in Frankfurt and New York and Dedicated Nodes that add Singapore and archive history. Archive reads use the same gRPC LedgerService as live ones, so clients only swap the endpoint URL.
