Sei is a first-tier blockchain optimized for digital asset transactions, and is a fully open-source general-purpose blockchain.
SEI is the native token of the project. Current use cases for SEI include:
Network Fees: Payment of transaction fees on the Sei blockchain.
DPoS verification node: SEI holders can choose to entrust the assets they hold to the verification node, or pledge SEI to run their own verification node to ensure network security.
Governance: SEI holders can participate in future governance.
Original Collateral: SEI can be used as collateral for native asset liquidity or for developing applications on Sei.
Fee Market: Users can pay tips to the verification node to get the transfer priority, and can share with the users who delegate to the verification node.
Transaction Fees: SEI can be used as transaction fees for exchanges built on the Sei blockchain.

The project consists of the following:
Twin-turbo consensus: Sei achieves a finality time of 400ms (10x faster than Solana and other high-performance blockchains).
Smart Block Propagation: Block proposals will be sent along with transaction summaries, allowing validators to build blocks locally. This will speed up user response.
Optimized block processing: Validators start processing blocks as soon as they receive them, which speeds up user response.
Single Slot Finalization: Before a block can be added to the network, validators need to reach consensus. Therefore, Sei is resistant to reorganization, resulting in a seamless user experience.
Parallelization: Sei achieved 20,000 orders per second through parallelization. This allows Sei to process independent transactions simultaneously, reducing transaction costs for users.
Front-running Prevention: Sei-based projects can use a local matching engine to prevent negative MEV, such as front-running.
Native Price Calculator: Validators provide trustless, decentralized price feeds for popular assets, bringing users a more reliable trading experience.
Permissionless Smart Contracts: Sei is a permissionless blockchain that allows developers to deploy Rust-based smart contracts.

The project has raised $35 million through three rounds of equity investment. A total of 2 billion SEI will be distributed to equity investors.
