Sei

Sei is one of the fastest blockchains, boasting a block finality time of approximately 400 milliseconds and a theoretical capacity of up to 12,500 transactions per second (TPS). This speed makes it ideal for high-frequency trading, real-time digital exchanges, and Web2-like user experiences.

The Twin-Turbo Consensus mechanism, an evolution of the Tendermint consensus, combines intelligent block propagation and optimistic block processing to reduce latency and increase throughput.

Sei V2 introduced a parallelized EVM, making it the first Layer 1 blockchain to combine Ethereum compatibility with parallel transaction processing. This allows developers to deploy Ethereum-based applications with minimal changes while benefiting from Sei’s performance improvements.

The Parallel Stack framework supports the development of Layer 2 solutions and rollups, enhancing scalability and reducing fees.

Sei is the first sector-specific Layer 1 blockchain tailored for trading, offering a native order-matching engine and built-in central limit order book (CLOB) to provide shared liquidity for DeFi applications.

Features like order batching help prevent frontrunning, ensuring fair execution of market orders.

Built on the Cosmos SDK, Sei is fully interoperable with the Cosmos ecosystem via the Inter-Blockchain Communication (IBC) protocol, enabling seamless asset transfers across IBC-compatible chains.

Sei supports both EVM and CosmWasm, bridging Ethereum and Cosmos ecosystems, which enhances developer flexibility.

SeiDB is an optimized database solution that handles high-speed transaction processing, reducing state bloat and enabling rapid state synchronization for node operators.

Sei is committed to carbon neutrality, aligning with the growing trend of environmentally conscious blockchain development.
