Sui is one of the most promising layer-1 blockchains to emerge in recent years, engineered for speed, scalability, and developer efficiency. Built to overcome the limitations of older blockchains like Ethereum and Bitcoin, Sui leverages a unique architecture and programming model to deliver near-instant transaction finality and ultra-low fees—making it ideal for decentralized applications (dApps), gaming, NFTs, and DeFi.
In this comprehensive guide, we’ll explore what Sui is, how it works under the hood, its core innovations, tokenomics, use cases, and how it compares to rivals like Aptos and Movement. Whether you're an investor, developer, or crypto enthusiast, this article will give you everything you need to understand Sui’s role in shaping the future of Web3.
What Is Sui?
Sui is a high-performance layer-1 blockchain designed from the ground up for scalability and user-friendly Web3 experiences. Launched on May 3, 2023, Sui stands out with its ability to process transactions in parallel, achieving theoretical throughput of up to 300,000 transactions per second (TPS)—far surpassing traditional chains that handle operations sequentially.
Unlike Ethereum’s account-based model, Sui uses an object-centric data model, where every digital asset—be it a token, NFT, or smart contract—is treated as an independent object with defined ownership and behavior. This architecture enables faster execution and reduces network congestion.
Sui also runs on a delegated proof-of-stake (DPoS) consensus mechanism, allowing users to stake their $SUI tokens with validators to secure the network and earn rewards. Combined with its custom Move programming language, Sui offers a secure, efficient foundation for next-generation dApps.
Who Created Sui? The Team Behind Mysten Labs
Sui was developed by Mysten Labs, a company founded in 2021 by five former engineers from Meta’s Novi Research division—the team behind the now-defunct Diem blockchain project.
Key figures include:
- Evan Cheng – CEO and former engineering leader at Apple and Facebook.
- Sam Blackshear – CTO who originally created the Move programming language at Meta.
- Adeniyi Abiodun – Chief Product Officer with experience at Oracle and VMware.
- George Danezis – Chief Scientist and professor of security and privacy at University College London.
- Kostas Chalkias – Chief Cryptographer with deep expertise in cryptographic protocols.
Backed by top-tier investors like Andreessen Horowitz, Binance Labs, and FTX Ventures, Mysten Labs raised $36 million in 2021 and an additional $300 million in 2022, valuing the company at $2 billion pre-launch.

How Does Sui Work? Core Technical Innovations
Sui’s performance edge comes from five key technological breakthroughs that redefine how blockchains process data.
1. Move Programming Language
Sui uses a modified version of the Move language, originally developed at Meta for the Diem blockchain. Move enhances security by treating code and assets as “objects” with strict rules around ownership and transfer.
This prevents common vulnerabilities like reentrancy attacks and double-spending. Developers can also bundle up to 1,024 actions into a single transaction—ideal for complex game mechanics or batch DeFi operations.
2. Parallel Transaction Execution
Most blockchains execute transactions one after another, creating bottlenecks during peak usage. Sui breaks this mold by processing transactions in parallel.
It analyzes whether transactions affect overlapping objects. If they don’t, they’re executed simultaneously across different validators. This allows Sui to scale horizontally—adding more nodes increases capacity without sacrificing speed.
3. Object-Centric Model
Instead of tracking balances in a global ledger (like Ethereum), Sui treats each asset as a self-contained object with its own metadata, owner, and permissions.
Objects are either:
- Single-owner: Fast transfers without consensus.
- Shared: Require validator agreement when modified.
This model simplifies state management and enables seamless sharding, contributing to sub-second finality and fees under $0.01.
4. Consensus Mechanism: Narwhal & Bullshark
Sui combines two components for consensus:
- Narwhal: A mempool protocol that collects and distributes transactions efficiently using a Directed Acyclic Graph (DAG).
- Bullshark: A DAG-based Byzantine Fault Tolerant (BFT) engine that finalizes transaction order.
Simple transactions bypass full consensus and settle in under 500 milliseconds. Complex ones involving shared resources take around 2 seconds—still blazing fast compared to most networks.
5. Horizontal Scalability
As demand grows, Sui scales by adding more validator nodes and computational workers. Each node processes multiple tasks in parallel thanks to its object model and consensus design.
Storage costs are managed via a fee redistribution system, ensuring long-term sustainability even under heavy load.
The SUI Token: Utility and Tokenomics
The native cryptocurrency of the Sui network is $SUI, with a fixed total supply of 10 billion tokens. As of now, approximately 3.08 billion are in circulation, with the remainder unlocking gradually until 2030.
Token Distribution Breakdown
- Community Reserve (50%): Funds ecosystem grants, research, and validator incentives.
- Early Contributors (20%): Allocated to the founding team and early employees; vested monthly.
- Investors (14%): Includes major VCs like a16z and Binance Labs; subject to lockups.
- Community Sale & Launchpool (6%): Sold via exchanges such as OKX and Bybit in 2023.
- Treasury (10%): Reserved for future development and strategic initiatives.
What Is $SUI Used For?
- Gas Fees: Pay for computation and storage on the network—typically less than $0.01 per transaction.
- Staking: Users delegate $SUI to validators to earn staking rewards (APR ~7–10%).
- Governance: Stakeholders vote on protocol upgrades and parameter changes.
- DeFi & NFTs: Used in liquidity pools, lending platforms, and minting digital assets.
- Gaming: Powers in-game economies with instant settlement and low friction.

Sui vs Aptos vs Movement: A Comparative Overview
| Feature | Sui | Aptos | Movement |
|---|---|---|---|
| Layer | Layer 1 | Layer 1 | Layer 2 (on Ethereum) |
| Architecture | DAG-based | Linear Blockchain | Linear Blockchain |
| Consensus | Narwhal + Bullshark (DAG-BFT) | AptosBFT | Snowman (Avalanche-based) |
| Programming Language | Move (Sui variant) | Move (Aptos variant) | Move (Aptos-focused) |
| Finality Time | ~0.5 sec | ~0.9 sec | ~1 sec |
