Sei Network (SEI): The High-Speed Layer 1 Blockchain Built for Decentralized Finance

Sei Network is a purpose-built Layer 1 blockchain engineered from the ground up to serve as the optimal foundation for decentralized finance (DeFi). By prioritizing performance, security, and user experience, it delivers the high throughput, low latency, and minimal costs required by next-generation trading applications, decentralized exchanges (DEXs), and financial protocols.

The Foundational Vision: A Blockchain Designed for Trading

Founded by Jeffrey Feng and Jayendra Jog, Sei was created to solve the critical bottlenecks—high fees, slow settlement, and frontrunning vulnerability—that plague DeFi on general-purpose blockchains. Its architecture is specifically optimized for the order-matching and settlement logic central to financial applications, positioning it as a dedicated trading layer for the digital asset ecosystem.

Innovative Technology: Twin-Turbo Consensus and Parallelization

At the heart of Sei's performance is its custom-built Twin-Turbo Consensus mechanism. This innovation combines intelligent block propagation and efficient transaction ordering to achieve remarkable metrics:

• High Throughput: Capable of processing tens of thousands of transactions per second (TPS).
• Rapid Finality: Sub-second transaction finality ensures trades settle almost instantly.
• Native Frontrunning Protection: A built-in mechanism to mitigate malicious MEV (Maximal Extractable Value) strategies like frontrunning, creating a fairer trading environment.

Sei V2: The Parallelized EVM Upgrade

A landmark evolution came with the Sei V2 upgrade, which introduced a parallelized Ethereum Virtual Machine (EVM). This breakthrough allows the network to:

• Run Ethereum smart contracts with full compatibility, welcoming the vast ecosystem of Solidity developers and existing dApps.
• Execute transactions in parallel rather than sequentially, dramatically increasing scalability and efficiency for complex DeFi operations.
• Maintain its signature speed and low costs while offering the familiarity and tooling of the EVM ecosystem.

The SEI Token: Fueling Network Operations and Governance

The native SEI token is integral to the network's economy and security, serving multiple essential functions:

• Transaction Fees: Used to pay for gas and execution costs on the network.
• Network Security: Staked by validators and delegators in its proof-of-stake (PoS) consensus to secure the chain.
• Governance: Grants holders the right to propose and vote on protocol upgrades and parameter changes.
• DeFi Collateral: Serves as a primary asset for lending, borrowing, and liquidity across the ecosystem.

Ecosystem Growth and Traction

Since its mainnet launch in August 2023, Sei has seen rapid ecosystem development. Its Total Value Locked (TVL) has shown consistent growth, driven by native DeFi innovations like DragonSwap and Bril Finance. The token's listing on major centralized exchanges shortly after launch provided significant liquidity and accessibility, accelerating adoption.
