Introduction to the Sui Blockchain – A Beginner’s Step-by-Step Guide
Introduction to the Sui Blockchain – A Beginner’s Step-by-Step Guide
- Understanding the Problem with Traditional Blockchains
Slow transaction speeds (Bitcoin averages ~7 TPS, Ethereum ~30 TPS).
High fees during network congestion.
Limited scalability as user adoption grows.
Complex programming models for developers.
- What is Sui?
A Layer-1 blockchain developed by Mysten Labs.
Built using the Move programming language (originally from Facebook’s Diem project).
Designed for speed, scalability, and low latency.
- Key Features
Parallel Execution: Unlike Ethereum’s sequential model, Sui executes independent transactions in parallel.
Object-Centric Model: Assets are treated as objects with unique IDs, making NFTs and gaming assets easier to manage.
Sub-Second Finality: Transactions confirm in milliseconds, not minutes.
- Step-by-Step – Why Choose Sui?
Step 1: Identify your use case (DeFi, NFT, gaming).
Step 2: Compare throughput needs → Sui offers ~297,000 TPS in tests.
Step 3: Consider cost efficiency → almost zero gas fees.
Step 4: Plan development using Sui SDK and Move language.

Real-World Example Imagine building a game where players trade swords, shields, and skins. On Ethereum, each trade costs gas and may take seconds. On Sui, each sword is an object, trading happens instantly, and fees are negligible.

Conclusion Sui solves scalability, cost, and latency—making it a foundation for the next generation of blockchain apps.

How does Sui’s object-centric model combined with parallel execution improve scalability and sub-second transaction finality compared to traditional blockchains, and what implications does this have for designing high-throughput dApps like NFT marketplaces or on-chain games?
Traditional blockchains use an account-based model, forcing all transactions into a single ordered sequence. Even unrelated actions must pass through consensus, creating bottlenecks, slow finality, and limited throughput. Sui takes a different path with an object-centric model, where every asset—coins, NFTs, game items, marketplace listingsis a separate object with its own ID and ownership. Transactions declare which objects they touch, so independent operations can be executed in parallel, while only shared objects need ordering. Combined with Sui’s DAG-based consensus (Narwhal + Bullshark/Tusk), this enables sub-second finality: independent transactions confirm almost instantly, and shared-object operations finalize in under a second. For dApps, this means NFT marketplaces can support mass minting and parallel trades without clogging, on-chain games can scale to thousands of players with real-time responsiveness, and DeFi apps gain higher throughput without fee spikes.
Sui is a Layer 1 protocol blockchain designed as the first internet-scale programmable blockchain platform.
