What Is Sui

Definition of Sui

Sui is a layer-1 blockchain platform designed for secure, scalable, and user-friendly global adoption. Sui stands out in the crypto industry as a high-performance blockchain that tackles common issues like slow transactions and complex user experiences. Launched in 2023, it was developed by Mysten Labs, founded by former Meta engineers including Evan Cheng and Sam Blackshear. The core concept revolves around an object-centric data model using the Move programming language, which enhances security and efficiency. Its ecosystem includes decentralized apps (dApps), DeFi protocols, and tools for Web3 developers, fostering innovation in areas like gaming and finance.

How Does Sui Work

Operational Mechanisms

Sui operates on a unique architecture that uses an object-centric model, where data is treated as objects rather than traditional accounts. This allows for parallel transaction processing, boosting speed.

Consensus and Security

It employs a delegated proof-of-stake (dPoS) mechanism combined with Narwhal and Bullshark protocols. Narwhal manages a directed acyclic graph (DAG) for efficient mempool handling, while Bullshark ensures consensus. Simple transactions bypass full consensus via Byzantine Consistent Broadcast, achieving finality in under a second. The Move language prevents common vulnerabilities, and features like zkLogin simplify user interactions without compromising security.

Technical Principles

Public and private keys secure ownership of objects, enabling seamless transfers. Smart contracts in Move are modular and safe, supporting complex dApps.

How Is New Sui Created

Issuance and Supply

Sui has a maximum supply of 10,000,000,000 SUI tokens, with a circulating supply of about 3,568,833,706 as of September 4, 2025.

Mining and Staking

New SUI is created through staking rewards in its dPoS system. Validators and delegators stake tokens to secure the network and earn rewards from transaction fees and inflation. The inflation model is designed to decrease over time, starting higher to incentivize early participation.

Reward Mechanisms

Rewards are distributed based on stake amount and network performance. There's no traditional mining like Proof-of-Work; instead, staking provides yields while supporting scalability.

The Use Cases of Sui

Payments and Transfers

Sui enables fast, low-cost cross-border payments, ideal for remittances.

DeFi and Smart Contracts

Its high throughput supports DeFi apps like lending, borrowing, and liquidity pools. Smart contracts power automated financial services.

NFTs and Governance

Users create and trade NFTs efficiently. Governance involves token holders voting on proposals, decentralizing decision-making.

Other Applications

Sui's ecosystem extends to gaming, where it handles high-volume interactions, and value storage amid volatility.
