What is Sei Blockchain?
Key Takeaways:
- Lightning-Fast Speed: Learn about its Twin-Turbo consensus, which finalizes transactions in under 400ms, making it one of the fastest chains in existence.
- EVM-Compatible Powerhouse: Supports Ethereum-based smart contracts through a parallelized EVM, allowing for faster and cheaper dApps.
- Built for Traders: The only major Layer 1 with a native Central Limit Order Book (CLOB), providing on-chain order execution and protection against frontrunning.
- Top-Tier Backing: Secured over $120M in funding from leading venture capital firms in the crypto space.
- Incredible Throughput: Engineered to handle up to 12,500 transactions per second (TPS), ready for real-world scale.
- Vibrant and Live Ecosystem: Home to a growing number of DeFi, NFT, and GameFi applications like Kryptonite, Levana, and Pallet Exchange.
Sei is a specialized, high-performance Layer 1 blockchain built to dominate the world of DeFi, digital asset trading, and next-generation decentralized applications (dApps). If you want to learn about blockchain speed, Sei offers near-instant transaction finality (~380ms), a unique built-in order matching engine, and an innovative parallelized EVM architecture. This provides developers a superior environment for building dApps that are both scalable and efficient, without sacrificing security or decentralization.
Constructed with the Cosmos SDK, Sei is designed for interoperability, allowing it to communicate seamlessly with other blockchains in the Cosmos ecosystem via the Inter-Blockchain Communication (IBC) protocol. The project is backed by a roster of top-tier investors, including Circle Ventures, Coinbase Ventures, Jump Crypto, and Multicoin Capital.

Top dApps in the Sei Ecosystem
Sei's speed and unique architecture have attracted a diverse range of developers. Here are some of the top projects to explore:
- Pallet Exchange: A leading NFT marketplace that benefits from Sei's fast block times and low fees, making the process of buying, selling, and minting NFTs smooth and affordable.
- DragonSwap: An automated market maker (AMM) based DEX that has already processed millions of swaps and over $1 billion in trading volume, demonstrating the network's high throughput capabilities.
- Silo: A lending and liquid staking protocol that offers concentrated liquidity and allows users to earn yield on their assets, including staked SEI.
Why Sei Stands Out: A Comparison
Unlike general-purpose chains that often struggle with the high demands of trading, Sei is custom-built to excel where others fail.
Sei’s unique combination of sub-second finality, a native order book, and compatibility with both the Cosmos (IBC) and Ethereum (EVM) ecosystems places it in a class of its own.
Who Built Sei?
Sei Labs was co-founded in 2021 by Jeffrey Feng, who has a background at Goldman Sachs and Coatue, and Jayendra Jog, an experienced software engineer from Robinhood. Based in San Francisco, the Sei Network mainnet went live in August 2023 and has since become one of the most-watched Layer 1 projects in the crypto space.

Final Thoughts
Sei is more than just another fast blockchain—it is a meticulously engineered platform designed to solve the core problems that have plagued decentralized trading for years. By focusing on speed, efficiency, and providing developers with unique tools like a native order book and a parallelized environment, Sei is positioning itself as the foundational layer for the next generation of DeFi, NFTs, and high-performance dApps.
How Does the Sei Blockchain Work?
To truly learn about Sei, you need to understand its core innovations. It's not just another general-purpose blockchain; its architecture is purpose-built for speed and trading efficiency.
1. Twin-Turbo Consensus
Sei’s Twin-Turbo consensus is a powerful evolution of the Tendermint consensus used by Cosmos. While a standard Tendermint block takes around 6 seconds to finalize, Sei achieves finality in less than 400 milliseconds. Think of it like an assembly line:
- Optimistic Block Processing: Instead of waiting for every single check to be completed before passing a product down the line, Sei starts working on the next step immediately. Validators begin processing blocks and propagating them before the full validation vote is complete, drastically cutting down wait times.
- Intelligent Block Propagation: To save time and resources, validators initially only share proposals containing transaction hashes. The full transaction data is sent later, reducing the amount of data clogging the network.
- Parallel Execution: This is Sei’s superpower. It can process transactions that don't affect the same state simultaneously, like having multiple cashiers serving different customers at once instead of a single queue.
2. Parallelized EVM (Sei v2)
Most blockchains, including Ethereum, use a single-threaded EVM, meaning transactions are processed one by one. Sei v2 introduced a Parallelized EVM. This allows the network to process multiple smart contracts at the same time, leading to:
- Lower Latency & Cheaper Fees: By handling tasks in parallel, the network reduces congestion, resulting in faster confirmation times and lower gas fees for users.
- Greater Scalability: This architecture makes it easier for Layer 2 rollups to settle on Sei, enhancing the ecosystem's overall capacity.
- Dual Environments: Developers can use both Ethereum's EVM (for Solidity contracts) and CosmWasm, giving them the flexibility to build with the tools they know best while accessing superior performance. This also means Sei is compatible with popular token standards like ERC-20 and ERC-721.
3. Built-in Order Matching Engine
This is a key differentiator for Sei. It is one of the only Layer 1 blockchains with a native Central Limit Order Book (CLOB) built directly into the protocol. For anyone wanting to learn about DeFi trading, this is a game-changer.
- What is a CLOB? It's the same system used by traditional stock exchanges like the NASDAQ to match buy and sell orders. By building this at the chain level, any dApp on Sei can access a deep, shared pool of liquidity.
- Frontrunning Protection: Sei uses frequent batch auctioning. It gathers all orders within a block, and executes them at the same uniform clearing price. This prevents malicious actors from seeing your trade and placing an order ahead of you to profit from your price movement.
- Ultimate Efficiency: All orders are placed and executed within a single block, creating a transparent, fast, and capital-efficient trading environment perfect for everything from spot trading to complex derivatives.
