Is "SUI" the Next After Bitcoin and Ethereum? Three Reasons Why Next-Generation Cryptocurrencies Are Drawing Attention

What Is Sui (SUI)? Key Concepts and Overview

Sui is a layer-1 blockchain platform developed by Mysten Labs, featuring its native crypto asset, the SUI token. The mainnet launched in May 2023, making it a relatively new blockchain. Sui was engineered to fundamentally solve the persistent problems of slow transaction speeds and high fees found in legacy blockchains like Bitcoin and Ethereum.

The development team includes many top engineers who previously worked on Meta’s Diem (formerly Libra) project. Founded in 2021, Mysten Labs rapidly scaled thanks to significant funding from leading venture capital firms. This strong technical team and deep financial backing form the foundation for Sui’s ongoing innovation.

Sui is a next-generation blockchain platform with a clear mission: to make digital assets fast, affordable, secure, and easily accessible to everyone. This vision serves as a guiding principle for true mainstream adoption in the Web3 era.

Primary Functions of the SUI Token

The SUI token is central to the Sui ecosystem and is primarily used for:

• Paying network fees (gas): The fundamental utility for all transactions.
• Participating in network operations and maintenance via staking: Token holders contribute to network security through staking.

By staking SUI tokens, holders can take part in the network’s consensus process and earn rewards for their contributions. Sui uses Delegated Proof of Stake (DPoS), allowing anyone to delegate SUI tokens to validators and participate in governance—no technical expertise required.

Three Key Reasons Sui Is a Standout Next-Gen Cryptocurrency

Sui is rapidly gaining attention as the “next-generation crypto asset after Bitcoin and Ethereum” thanks to its innovative features, which deliver practical benefits and dramatically enhance the user experience.

The most critical advantages are:

• Exceptional high-speed processing: Supports large-scale transaction processing that traditional blockchains can’t achieve.
• Low, stable fees: Offers an economical and predictable environment for users.
• Intuitive usability for newcomers: Designed for easy, straightforward operation, even without technical expertise.

These features enable Sui to overcome the legacy usability barriers of earlier blockchains and expand Web3 to the mainstream.

1. Exceptional High-Speed Processing — Scalability Through Parallel Execution

Sui’s most prominent feature is its dramatically faster transaction processing compared to conventional blockchains. Its unique architecture enables parallel execution of many transactions, achieving theoretical throughput up to 300,000 transactions per second—over 10,000 times faster than Ethereum’s typical 20–30 TPS.

In rigorous tests, Sui has processed around 297,000 transactions per second (with 10,000 finalized in just 0.39 seconds), ranking just behind Solana among layer-1 blockchains. This speed is crucial for blockchain adoption at the scale of hundreds of millions or billions of users.

Technologies Behind Fast Processing

Sui’s speed is powered by two core innovations: an object-centric data model and a design that omits global consensus for simple transactions.

Older blockchains like Bitcoin and Ethereum process all transactions sequentially, which limits throughput due to global ordering requirements.

Sui, by contrast, manages assets and data as independent objects, each with its own history. Transactions that don’t affect each other can be processed in parallel, dramatically boosting network capacity.

For example, a payment from A to B and another from C to D are independent and can be processed simultaneously, without strict ordering. This approach—called “causal order”—lets Sui instantly confirm simple, single-writer transactions via validator majority voting, skipping global consensus.

As a result, straightforward actions like payments and NFT issuance are finalized almost instantly, eliminating wait times for users.

Managing Complex Transactions That Require Consensus

Transactions involving shared assets—such as swaps on decentralized exchanges (DEX) or multi-signature changes—require full consensus and global ordering. Sui uses a sophisticated two-stage consensus engine, Narwhal & Bullshark, for these cases:

• Narwhal: Aggregates proposed transactions into a mempool, guaranteeing data availability and reliability for later processing.
• Bullshark: Uses Byzantine Fault Tolerance (BFT) algorithms to efficiently determine final transaction order, ensuring robust consensus even with malicious nodes.

This two-stage system makes even complex transactions fast and reliable; recent research reports throughput above 400,000 transactions per second.

Sui’s Scalability Proven in Practice

Sui’s cumulative transaction count has exceeded 2.58 billion, surpassing Ethereum’s 2.57 billion and demonstrating real-world performance—not just theoretical potential.

With blockchain adoption poised to reach hundreds of millions or billions of users, high-performance chains like Sui could become the backbone of Web3 infrastructure.

2. Low, Stable Fees — Solving Gas Price Surges

Sui’s second major advantage is its very low and stable transaction fees (gas), which are crucial for practical, everyday blockchain use.

On Bitcoin and Ethereum, congestion can drive fees to extreme levels—sometimes tens or even hundreds of dollars—making small transactions impractical. Ethereum, especially, saw massive gas spikes during DeFi and NFT booms.

Sui’s parallel processing and scalable architecture fundamentally prevent congestion and suppress fee surges during periods of high demand. Network capacity expands with demand, so fees remain stable even as usage grows.

Tokenomics That Stabilize Gas Fees

Sui uses an algorithmic economic model to keep gas fees stable over time. Fees adjust automatically based on demand, and validator rewards are designed for consistency.

During periods of high demand, validators can increase their resources (CPU, memory, storage) to process more transactions without raising fee rates—so their revenue grows while user costs remain predictable.

In practice, Sui’s gas fees for transfers and basic functions are kept below a few cents, making microtransactions affordable. Excess fee revenue is saved in a storage fund to cover future data costs, ensuring a sustainable, user-friendly design.

“Sponsored Transactions”: No Gas Fees for End Users

Sui’s “Sponsored Transactions” feature allows DApp developers to pay transaction fees on behalf of users, so users can interact with apps without worrying about fees.

This creates a frictionless experience—making Sui apps as easy and familiar to use as traditional web services—and removes a major adoption barrier for blockchain technology.

3. Intuitive Usability — User Experience on Par with Web2

Sui is designed for ease of use, even for blockchain beginners. Its concept is to deliver Web3 benefits with Web2-level usability, ensuring that first-time users can interact comfortably and confidently.

Seamless Login with Existing Accounts (zkLogin)

Sui’s “zkLogin” enables users to log in via Google, Apple, Facebook, and other mainstream accounts, using zero-knowledge proof cryptography—no need to manage private keys or mnemonic phrases.

This eliminates the biggest hurdle to mainstream blockchain adoption and lowers the barrier for everyday users.

Official Wallet for Simple Operations

Sui offers the “Slush Wallet” (formerly Sui Wallet) as a browser extension and mobile app, providing easy token transfers, NFT display, and staking via an intuitive interface.

The staking feature is especially simple—just click a button to start earning rewards, with no technical setup required.

Consistent User Experience Through Standardized Protocols

Sui enforces unified technical standards—such as object display for NFTs and flexible royalty settings for marketplaces—so users enjoy a consistent experience across apps and platforms.

Sui’s multi-faceted user experience improvements allow beginners to interact with blockchain technology seamlessly, helping draw more users to Web3.

Comparing Sui to Bitcoin and Ethereum

Sui is a next-generation blockchain combining speed, low cost, and usability. Here’s how Sui compares to Bitcoin and Ethereum:

Bitcoin is focused on value storage and payments, establishing itself as digital gold. Ethereum pioneered smart contracts and DApps, driving DeFi and NFT growth but faces scaling and fee limitations.

Sui overcomes these limitations with high-speed processing, low fees, and exceptional usability—positioning itself as a next-generation blockchain infrastructure.

Technical Differences: Move Language and Object Model

Ethereum uses Solidity and EVM; Sui uses Move and a unique object model. Move builds critical blockchain security—like asset ownership and double-spend prevention—directly into the language, providing a safer environment than Solidity. Sui therefore offers stronger protection against smart contract bugs and hacks.

Sui’s Challenges and Future Outlook

As a newer platform, Sui faces hurdles:

• Network decentralization: Validator count and geographic diversity are still developing.
• Ecosystem maturity: The number and scale of DApps and DeFi projects.

Sui’s DeFi TVL and user base still trail Ethereum. For Sui to become a “third pillar,” it must build a robust track record and expand its ecosystem.

Expanding Use Cases and Future Prospects for Sui

Growth in DeFi, NFT, and Gaming

Sui is rapidly gaining traction in finance (DeFi) and entertainment (games, NFTs), with live projects emerging across the ecosystem.

• DeFi: Projects like Cetus (DEX) and SuiLend (lending protocol) are scaling rapidly, leveraging Sui’s speed and affordability for superior user experiences.

• Gaming: Innovative titles such as Abyss World and Run Legends blend NFTs with health gamification. Sui’s sponsored transaction feature and high-speed processing solve legacy blockchain game issues like delays, high costs, and complexity.

Major developer Orange Comet has partnered with Mysten Labs to build blockchain games based on high-profile IP, including “The Walking Dead.”
