Launched in August 2023, Sei (SEI) is a high-performance Layer 1 blockchain specifically engineered to solve the scalability issues faced by decentralized exchanges and high-frequency trading applications. Originally built on the Cosmos SDK, the network underwent a major evolution with the launch of Sei v2, which introduced the concept of the Parallelized EVM. This architectural breakthrough combines the developer-friendly environment of Ethereum with the blistering speed of Solana, utilizing "optimistic parallelization" to process thousands of transactions simultaneously rather than sequentially. The native token, SEI, fuels this ecosystem; it is used to pay for network gas fees, staked to secure the Twin-Turbo consensus mechanism, and serves as a governance tool for protocol upgrades.
