Sei (SEI) is a Layer 1 blockchain protocol designed to serve as the foundational infrastructure for decentralized finance (DeFi) applications, focusing on the needs of order book-based decentralized exchanges (DEXs), and to build the infrastructure for the exchange of digital assets.
Launched with the objective of addressing the performance and liquidity challenges inherent in existing DeFi platforms, Sei aims to provide a high-throughput, low-latency environment optimized for trading and other financial applications.
The native cryptocurrency of the Sei network is SEI, utilized for transaction fees, staking, governance, and incentivizing liquidity within the ecosystem. Sei’s ecosystem supports a wide range of applications across DeFi, gaming, NFTs, and more.
Sei facilitates real-time order execution and reduces reliance on external liquidity providers to support a trading experience comparable to that of centralized exchanges while maintaining the security and decentralization benefits of blockchain technology.
Central to its technology stack are several key features. Its Twin-Turbo Consensus and Optimistic Block Processing mechanisms collectively enhance throughput, achieving faster block times and increased finality, to support applications requiring swift transaction processing, such as order books used in trading platforms.
Through Parallel Order Execution, Sei allows for simultaneous processing of independent market orders, boosting throughput, particularly beneficial at higher transaction volumes
Sei incorporates single-block order execution and frequent batch auctioning, among other features as part of its native Order-Matching Engine, to optimize trading execution and reduce the potential for market manipulation like frontrunning.
