Sui is emerging as one of the most promising Layer 1 blockchains in the Web3 space, capturing attention for its high performance, innovative consensus mechanism, and developer-friendly design. Built by former Meta (Facebook) engineers, Sui aims to solve long-standing blockchain challenges like scalability, speed, and user experience—particularly for applications in gaming, social platforms, and dynamic NFTs.
This article explores Sui’s core architecture, ecosystem development, and how it compares with its closest competitor, Aptos—offering a comprehensive look at what makes Sui a strong contender in the race to power the next generation of decentralized applications.
The Founders Behind Sui: Mysten Labs
Sui was developed by Mysten Labs, a team founded by veterans from Meta’s Novi Research team, which originally worked on the Diem blockchain project. While Sui shares DNA with Diem through its team, it diverges significantly in purpose and technical design.
Unlike Diem—which was designed for lightweight wallet-to-wallet payments—Sui targets complex, high-throughput use cases such as metaverse applications and real-time digital asset interactions. Despite common origins, Sui has no official affiliation with Meta.
The founding team brings deep expertise across distributed systems, cryptography, and programming languages:
- Evan Cheng – CEO, former Director of Engineering at Meta and Novi R&D lead.
- Sam Blackshear – CTO, creator of the Move programming language.
- Adeniyi Abiodun – Chief Product Officer, ex-Product Lead at Novi.
- George Danezis – Chief Scientist, formerly with Chainspace and Microsoft Research.
- Kostas Chalkias – Lead Cryptographer, with experience at R3 and NewCrypt.
This combination of talent positions Mysten Labs as one of the most technically capable teams in the blockchain space.
Funding and Tokenomics
Sui has attracted significant institutional backing, reflecting strong market confidence.
Funding Rounds
- Series A (December 2021): Raised $36 million led by top-tier investors including a16z, Redpoint, Lightspeed, Coinbase Ventures, Samsung NEXT, and Electric Capital.
- Series B (Reported): An additional $200 million reportedly raised, with participation from FTX Ventures. Total funding is estimated at **$236 million**.

SUI Token Overview
- Total Supply: Fixed at 10 billion SUI tokens.
Use Cases:
- Staking to secure the network
- Paying transaction and storage fees
- Governance voting
- Native asset for dApps
Notably, Sui does not include a token burn mechanism. Instead, a portion of tokens is released at mainnet launch, with the remainder distributed over time as staking rewards.
Core Technical Innovations
Sui is engineered for speed, scalability, and developer flexibility. It tackles the blockchain "impossible trinity" by prioritizing performance without sacrificing decentralization or security.
Parallel Transaction Processing
Unlike traditional blockchains that process transactions sequentially, Sui executes transactions in parallel, drastically reducing latency and increasing throughput. This is achieved through an object-centric data model where independent transactions (e.g., simple token transfers) are processed instantly without waiting for global consensus.
Two Consensus Paths
Sui intelligently routes transactions based on complexity:
- Simple Transactions: Independent actions (like sending tokens) use a leaderless Byzantine Broadcast protocol. These finalize in under a second.
- Complex Transactions: Actions involving shared state (e.g., auctions) use a variant of Byzantine Fault Tolerance (BFT) called Narwhal & Tusk, finalizing in 2–3 seconds.
This dual-path approach allows Sui to scale efficiently while maintaining security.
Narwhal & Tusk: Decoupling Memory Pool and Consensus
One of Sui’s most groundbreaking innovations is the separation of the mempool (transaction pool) from the consensus layer—a departure from monolithic designs used by most PoS blockchains.
- Narwhal: A mempool protocol that ensures data availability and broadcasts transactions efficiently across validators.
- Tusk: An asynchronous consensus engine that orders transactions using shared randomness, minimizing communication overhead.
This modular design enables horizontal scaling—validators can add more machines to handle increased load—and improves resilience under poor network conditions.
Gas and Storage Fee Model
Sui introduces a unique fee structure that enhances predictability and user experience.
Predictable Gas Pricing
At the start of each epoch, validators vote on a reference gas price. This creates stable, low-cost transactions—even during peak usage—because throughput scales linearly with validator resources.
Validators who consistently meet performance targets earn higher rewards; those who lag risk reduced stake delegation.
Separated Storage Fees
Storage costs are calculated in USD-equivalent terms and paid into a Storage Fund, which compensates validators for long-term data storage. Users can delete old data to reclaim storage credits—a powerful incentive for efficient chain usage.

Sui vs. Aptos: Key Differences
While both Sui and Aptos stem from Meta’s Novi team and use the Move programming language, they differ significantly in architecture and execution.
| Feature | Sui | Aptos |
|---|---|---|
| Consensus Mechanism | Narwhal & Tusk (asynchronous) | AptosBFT (partial async HotStuff derivative) |
| Transaction Execution | Object-centric, parallel by default | Account-centric with parallel execution |
| Gas Model | Predictable pricing + storage fund | Dynamic gas pricing |
| Developer Tools | Cross-chain NFT bridging (SuiEcho), non-custodial asset distribution (Handshake) | Native SDKs focused on Aptos ecosystem |
Sui’s object model allows finer-grained parallelism compared to Aptos’ account-based system. Additionally, tools like SuiEcho enable NFTs from Ethereum (e.g., Bored Ape Yacht Club) to be mirrored on Sui, helping onboard existing communities.
Ecosystem Development
Though newer than Aptos, Sui’s ecosystem is rapidly expanding.
Key dApps and Tools
- Sui Wallet – Official non-custodial wallet.
- Ethos Wallet – Enhanced UX-focused wallet with social recovery.
- Sui Name Service (SNS) – Human-readable addresses.
- Scallop – Native lending protocol.
- Turbos Finance – DeFi platform for leveraged yield strategies.
Mysten Labs also supports developer growth through grants and hackathons.
Performance Benchmarks
Early benchmarks show impressive results:
- Up to 160,000 TPS when Narwhal is paired with Tusk.
- Simple transactions finalize in under 1 second.
- Throughput scales linearly with hardware—no theoretical upper limit.
While these figures come from controlled environments, they suggest Sui could outperform many existing L1s once mainnet adoption grows.
Frequently Asked Questions (FAQ)
Q: Is Sui affiliated with Meta or Facebook?
A: No. Although the core team came from Meta’s Novi research lab, Sui is independently operated with no formal ties to Meta.
Q: What programming language does Sui use?
A: Sui uses Move, a secure-by-design language originally developed for Diem. It emphasizes resource safety and prevents common smart contract vulnerabilities.
Q: How does Sui achieve high transaction speed?
A: Through parallel execution, object-centric data modeling, and the Narwhal & Tusk consensus framework that decouples transaction dissemination from ordering.
Q: Can I bridge NFTs from Ethereum to Sui?
A: Yes—via tools like SuiEcho, users can mint Sui-based versions of their Ethereum NFTs and use them within the Sui ecosystem.
Q: Is Sui more decentralized than Aptos?
A: Both networks are still evolving. As of mid-2022, over 5,000 Sui nodes operated across 65 countries. True decentralization will depend on long-term validator distribution and community participation.
Q: When did Sui launch its mainnet?
A: Sui launched its mainnet in May 2023. Since then, it has seen growing developer activity and dApp deployment.
Final Thoughts: Where Does Sui Stand?
Sui stands out with its cutting-edge architecture, robust team, and forward-thinking tokenomics. While Aptos currently leads in ecosystem size and community momentum, Sui’s technical advantages—especially in parallelization and UX-focused tooling—position it as a serious competitor.
Success won’t come from technology alone. As industry experts note, market adoption depends on developer engagement, business development, and real-world utility. But with strong funding, open-source collaboration (e.g., Celo adopting Narwhal & Tusk), and tools like Handshake lowering entry barriers for non-crypto users, Sui is well-equipped for long-term growth.
