Primary features
Sui is a next-generation Layer-1 blockchain with an object-centric data model, the Move programming language, very high throughput, and usability enhancements like gas sponsorship and zkLogin.
- Object-centric model for assets, mutable & immutable objects
- Smart contracts written in Move with Move Prover verification
- Parallel transaction execution, simple transfers bypass consensus
- Low latency & fast finality even under heavy load
- Dynamic fee / storage rebate system
- Features such as zkLogin, sponsored transactions
Work principles
Sui works by distinguishing different kinds of objects & transactions, using a hybrid consensus stack (Narwhal, Bullshark, Mysticeti) and optimizing for parallelism, efficiency, and scalability.
- Transactions touching only individually owned objects skip global consensus
- Shared objects require full consensus protocols
- Consensus layers: Narwhal for mempool / data availability, Bullshark / Tusk / Mysticeti for ordering & finality
- Parallel execution of non-conflicting transactions
- Storage fund & rebate model: storage fees paid, refunds when objects deleted
- Governance via Delegated Proof of Stake (DPoS) with staking SUI
User benefits
Users and developers gain from Sui through low fees, fast transactions, flexible programmability, and more accessible onboarding; its community often praises its performance and usability.
- Very low transaction fees thanks to efficient execution & storage design
- Sub-second or near-instant finality for many transactions
- High throughput enabling scalable apps (gaming, DeFi, NFTs)
- More secure smart contracts via Move and formal verification
- Easier onboarding with features like zkLogin & sponsored transactions
