Key Takeaways
- Sui (SUI) is a high-speed layer 1 blockchain built by Mysten Labs, a company founded in 2021 by former Meta engineers.
- The project prioritizes scalability and a smooth user experience for Web3 applications (dApps).
- The SUI token is the lifeblood of the Sui ecosystem, powering transactions (gas fees), staking for rewards, voting on governance proposals, and facilitating an in-platform digital economy.
What Is Sui (SUI)?
Sui (SUI) is a crypto project aiming to build a faster and more scalable Layer-1 blockchain network. The project aims to be a blockchain network that can support the next generation of decentralized applications (dApps) and cater to a much larger user base than current blockchain solutions.
Mysten Labs was founded in September 2021 by engineers from Diem (formerly Libra), Meta’s wound-down payments project, where the Move language began. Co-founder Evan Cheng is the CEO. Mysten raised $36 million in a round led by Andreessen Horowitz in December 2021, and Sui’s mainnet launched on May 3, 2023.
How Does Sui (SUI) Work?
Sui (SUI) focuses on delivering a user-friendly Web3 experience. Here’s a deeper dive into how the project works:
Sui Move Language
Like Ethereum’s Solidity, Sui Move is a blockchain programming language intended for building apps on the Sui blockchain. It is secure and memory-safe, which can help prevent hacking and other security issues.
Parallel Transaction Execution
This refers to Sui’s ability to process multiple transactions simultaneously, which can significantly improve transaction speeds compared to traditional blockchains that process transactions individually.
Sui Consensus Engine
This mechanism ensures agreement on the state of the Sui blockchain network. Sui uses delegated proof of stake: SUI holders stake with validators, who also vote on protocol changes. Since July 2024, validators have agreed on transaction order with Mysticeti, a DAG-based consensus protocol that Sui says reaches consensus in about 300 milliseconds.

Is Sui (SUI) A Good Investment?
Pros
- Speed And Scalability – Sui boasts high transaction throughput and low latency, allowing faster transaction processing without compromising validation times. This is achieved through its unique architecture, which facilitates parallel transaction processing.
- User-Friendly – Sui is designed to be user-friendly, attracting developers and users who want ease of use.
- DeFi Potential – Sui’s blockchain programming language, Move, has security features that make it suitable for building decentralized finance (DeFi) protocols on the Sui blockchain.
Cons
- Limited Adoption – Sui is a relatively new player in the blockchain space, and its ecosystem is still under development. On October 7, 2026, apps on Sui held about $528 million in total value locked, down from a peak of about $2.64 billion in October 2025. Sui held about $484 million in stablecoins, and its DEXs handled about $1.5 billion in the previous 30 days (DefiLlama).
- Developing Technology – While Sui promises high transaction throughput, it hasn’t reached those levels yet.
- Security Concerns – While Sui Move is designed to be secure, apps on Sui have been hacked. In May 2025, an attacker drained about $223 million from the Cetus exchange through a flaw in a math library. Funds frozen on Sui were recovered after a validator vote (90.9% of stake in favor), and Cetus relaunched on June 8, 2025. The mainnet also halted for about 2.5 hours on November 21, 2024, and for about six hours on January 14, 2026.
