SUI is emerging as one of the most promising Layer 1 blockchains designed to meet the growing demand for speed, scalability, and security in the Web3 ecosystem. With recent high-profile incidents on other networks highlighting the need for more robust infrastructure, SUI stands out by leveraging innovative architecture and the Move programming language to deliver internet-scale performance. In this guide, we’ll explore what makes SUI unique — from its team and technology to its tokenomics and future potential.
The Vision Behind SUI
SUI was built to solve fundamental limitations in existing blockchain networks: low throughput, high latency, and rising transaction costs. Unlike traditional blockchains that struggle under increased usage, SUI is engineered from the ground up for horizontal scalability. Its goal? To become the first programmable blockchain capable of supporting applications for billions of users without sacrificing speed or cost-efficiency.
Importantly, SUI is not a fork or derivative of Meta’s Diem (formerly Libra) project. While it shares some conceptual roots through the Move language, SUI is a completely independent initiative developed by Mysten Labs with a fresh architectural approach focused on real-time transactions, massive throughput, and minimal fees.

Founding Team and Technical Expertise
SUI was created by former members of Novi Research — Meta’s advanced blockchain research division. The founding team brings deep expertise in distributed systems, cryptography, and smart contract development.
Key leaders include:
- Evan Cheng – CEO, previously led engineering for Meta’s blockchain wallet
- Sam Blackshear – CTO, creator of the Move programming language
- Adeniyi Abiodun – COO
- George Danezis – Chief Scientist, renowned in privacy-preserving technologies
Together, they spent years working on Diem and developing core innovations in consensus mechanisms, zero-knowledge proofs, and secure smart contract execution. Their experience directly informed SUI’s design, particularly its use of Move and novel consensus architecture.
After leaving Meta, the team founded Mysten Labs in 2021 to build a new blockchain platform unencumbered by legacy constraints — resulting in SUI.
Funding and Market Confidence
Mysten Labs raised $36 million in Series A funding in December 2021, led by Andreessen Horowitz (a16z), with participation from Redpoint, Lightspeed Venture Partners, and Coinbase Ventures. This early backing signaled strong confidence in SUI’s technical vision.
Reports suggest the company is targeting a $2 billion valuation in its upcoming Series B round, indicating continued institutional interest as mainnet adoption grows.
Core Architecture: Narwhal & Tusk
At the heart of SUI lies an innovative two-layer consensus framework: Narwhal & Tusk.
- Narwhal ensures data availability — meaning all transaction data is reliably shared across validators.
- Tusk handles transaction ordering — determining the sequence in which transactions are finalized.
This separation allows SUI to process transactions asynchronously. Crucially, SUI does not require global consensus for every transaction. Instead, it uses causal ordering, where only transactions involving shared data go through full consensus. Independent transactions (like sending tokens between unrelated accounts) can be finalized instantly without waiting for network-wide agreement.
This breakthrough drastically reduces latency and enables parallel processing — allowing SUI to scale horizontally with near-linear performance gains as more nodes join.
Scalability That Grows With Demand
Traditional blockchains face a trade-off: increased usage leads to congestion and higher fees. SUI flips this model.
In benchmark tests, a single unoptimized validator on an 8-core M1 MacBook Pro achieved over 120,000 transactions per second (TPS). As more validators join, throughput increases proportionally — meaning the network becomes faster and cheaper under load.
Because worker nodes can utilize all CPU cores efficiently and transaction fees decrease during peak times, SUI offers a user experience closer to centralized services — but with full decentralization and security.
Developer Experience: Building on SUI
SUI provides a comprehensive Software Development Kit (SDK) designed to streamline dApp development. Key features include:
- Intuitive tools for debugging Move contracts
- Pre-built libraries for common financial primitives
- Faster deployment cycles with reduced need for manual audits
The platform's object-centric data model simplifies state management compared to account-based models (like Ethereum), making it easier for developers — especially those transitioning from Web2 — to build performant, secure applications.

Security Through Move Language Design
Security is foundational to SUI’s architecture — largely thanks to the Move programming language.
Originally developed at Meta for Diem, Move emphasizes resource safety by design:
- Digital assets are treated as unique resources that cannot be copied or accidentally deleted
- Code enforces strict rules about how resources can be moved or modified
- Prevents common vulnerabilities like reentrancy attacks (which have led to millions in losses on other chains)
Move modules act like smart contracts but enforce data encapsulation — resources are transparent inside their defining module but opaque outside it. This prevents unauthorized access and enhances auditability.
Additionally, Move supports formal verification via a specification language, enabling developers to mathematically prove correctness before deployment — a major step toward enterprise-grade reliability.
Tokenomics: The Role of SUI
The native SUI token serves multiple critical functions within the ecosystem:
Use Cases of SUI Token
- Pay for transaction fees and storage
- Stake in Proof-of-Stake (PoS) consensus to earn rewards
- Participate in on-chain governance (e.g., protocol upgrades)
- Serve as collateral in DeFi applications
Supply and Distribution
- Maximum supply: 10 billion SUI
- A portion will be circulating at mainnet launch
- Remaining tokens will be distributed over time as staking rewards
- No built-in deflationary mechanism, but supply is capped
Notably, storing data on-chain requires locking up SUI as collateral — which reduces circulating supply and creates natural economic pressure as network activity grows.
Ecosystem Growth and Adoption
Since its incentivized testnet launched in mid-2023, developer engagement on SUI has grown exponentially. Projects spanning DeFi, NFTs, gaming, and social platforms are actively building on the chain.
The combination of low-latency finality, high throughput, and developer-friendly tooling makes SUI attractive for consumer-grade applications that demand responsiveness and scalability — areas where older blockchains often fall short.
Frequently Asked Questions (FAQ)
Q: Is SUI related to Aptos?
A: Both SUI and Aptos use the Move programming language and were founded by ex-Meta engineers. However, they are separate projects with different architectures — SUI focuses on parallel execution and causal ordering, while Aptos uses a more traditional sequential model.
Q: How fast are SUI transactions?
A: Most transactions achieve finality in under a second. Independent operations don’t require global consensus, enabling near-instant confirmation times.
Q: Can anyone run a validator on SUI?
A: Yes — SUI is a permissionless network. Anyone can stake SUI tokens and participate in validation, contributing to decentralization and earning staking rewards.
Q: What makes SUI different from Ethereum or Solana?
A: Unlike Ethereum (which relies on sequential processing) or Solana (which prioritizes speed via centralization trade-offs), SUI achieves high throughput through parallel execution and a novel consensus design that scales horizontally without sacrificing decentralization.
Q: Is Move difficult to learn for developers?
A: While Move has a learning curve, its strong type system and focus on safety make it accessible — especially for developers familiar with Rust or similar languages. Comprehensive documentation and SDKs further lower entry barriers.
