Sei Network

About

Sei Network is a Layer 1 EVM blockchain designed for high-performance, real-time applications. It enables developers to create high-frequency applications with quick execution and cheap transaction costs. The network can handle up to 10,000 transactions at a cost of approximately $0.05 while maintaining continuous performance. It focuses on addressing critical blockchain issues such as speed, scalability, and decentralization. This is achieved through parallel processing, Twin Turbo consensus, and full Ethereum (EVM) compatibility. Because of this setup, Sei Network has quickly grown within the Web3 ecosystem. Key Features of Sei Network: • Handles multiple transactions at the same time using parallel processing, which reduces congestion and improves scalability. • A built-in on-chain order book allows developers to build high-performance decentralized exchanges (DEXs) with smoother execution. • Fully compatible with Ethereum (EVM), so developers can deploy existing smart contracts without changes • Uses order batching and frequent batch auctions to reduce frontrunning and support fair trading. • It supports DeFi, NFTs, GameFi, and social apps on its high-speed infrastructure. Sei Network Milestones: Year Key Achievements 2021-2022 Sei was founded by Sei Labs (Jeff Feng & Jayendra Jog) with a clear focus on building a "sector-specific" L1 architecture. The project raised $5M in seed funding from Multicoin Capital, Coinbase Ventures, and Jump Crypto. The Atlantic-1 Testnet went live, introducing the "Twin-Turbo" consensus. 2023 Sei secured another $30M in funding, reaching an $800M valuation. It reached 380 ms finality, making it the fastest L1 in production at that time. A native Order Matching Engine was added at the consensus layer to help prevent front-running. 2024 Sei announced and rolled out Sei v2, the world’s first Parallelized EVM. Optimistic Concurrency Control (OCC) was introduced to handle non-conflicting transactions at the same time. 2025 Sei introduced the Giga Upgrade, which aims for a 50x increase in throughput. Autobahn Consensus was implemented utilizing a multi-proposer configuration with parallel lanes.
