Key Features

Sui demonstrates capacity beyond the transaction processing capabilities of established systems. It’s the first internet-scale programmable blockchain platform.
  • Parallel execution: Most transactions process in parallel
  • Instant finality: Sub-second transaction finality
  • High throughput: Scales with additional resources
Smart contracts written in Move provide safety and expressiveness for managing digital assets.
  • Asset-oriented: Objects are first-class citizens
  • Safe by design: Prevents common security vulnerabilities
  • Developer-friendly: Clear syntax and powerful abstractions
Sui’s object model enables flexible ownership and parallel transaction execution.
  • Owned objects: Fast-path execution without consensus
  • Shared objects: Coordinated updates via consensus
  • Dynamic fields: Extensible object storage
A permissionless set of validators secures the network through delegated stake.
  • Byzantine fault tolerant: Tolerates up to 1/3 faulty validators
  • Epoch-based: Regular validator set reconfiguration
  • Staking rewards: Incentivizes honest participation

​
Use Cases

DeFi

Build decentralized exchanges, lending protocols, and synthetic assets with programmable transaction blocks.

Gaming

Create on-chain games with fast finality, low latency, and composable game assets.

NFTs & Digital Assets

Mint and trade unique digital assets with flexible ownership models.

Payments

Power instant, low-cost payments at physical and online points of sale.

​
Architecture Highlights

Sui makes the vast majority of transactions processable in parallel by using simpler and lower-latency primitives for common use cases like payment transactions and asset transfers.
