Sei (SEI) is a Layer 1 blockchain specifically designed to optimise the trading of digital assets, particularly for decentralised exchanges (DEXs). It combines high-performance elements from both Solana and Ethereum, aiming to deliver a developer-friendly environment enabled by a high-speed Ethereum Virtual Machine (EVM) chain. This unique architecture helps facilitate faster and more efficient digital asset trading.
Sei operates on a Layer 1 blockchain infrastructure leveraging the Cosmos SDK and Tendermint Core, designed for high-frequency trading and optimised digital asset transactions. Its unique Twin-Turbo Consensus Mechanism enhances transaction speed, security, capital efficiency, and decentralisation. By supporting both the Ethereum Virtual Machine (EVM) and CosmWasm, Sei allows developers to deploy dApps seamlessly across its network. It employs parallel-transaction processing to further enhance scalability and transaction efficiency.
Sei's architecture is tailored towards high-speed, scalable, and secure applications, making it ideal for:
Sei was co-founded by Jayendra Jog, a former software engineer at Robinhood, and Jeff Feng, a UC Berkeley graduate with experience in finance and venture capital. Motivated by the decentralisation opportunities in the wake of the GameStop scandal, the project launched its mainnet in 2022, combining elements of Ethereum and Solana for enhanced transaction speed and scalability. In 2024, the platform introduced Sei V2, an upgrade that made it the first to implement a parallelised EVM chain, supported by a $10 million Sei Creator Fund to propel ecosystem development. The platform has continually evolved, backed by leading investors like Multicoin, Coinbase Ventures, and Jump.
