New York - May 19, 2025 - Sei Labs, the main contributor to the Sei blockchain (the most performant Layer 1 blockchain), today released the Sei Giga Whitepaper. The whitepaper outlines Sei blockchain's path to becoming the first multi-proposer EVM Layer 1. Sei Giga leverages parallel block proposals to solve bottleneck issues, aiming to expand EVM capabilities through performance optimization innovations in data availability, consensus, execution, and storage.
By combining a high-performance consensus mechanism with a from-scratch EVM execution client, Sei Giga aims to break through traditional blockchain network limitations, achieving significant improvements in transaction throughput, latency, and scalability. The key features of Sei Giga include:
· 5 billion Gas throughput and approximately 200,000 transactions per second (TPS), optimized for scalable high-performance applications.
· Finality under 400 milliseconds: Fast transaction confirmation, achieving low-latency, high-speed performance.
· EVM compatibility: Supporting Ethereum smart contracts (Solidity, Vyper), facilitating integration with Ethereum applications.
· Autobahn consensus protocol: Adopting a multi-proposer architecture, supporting parallel block proposals, achieving a 50-fold throughput improvement.
· Entirely new execution client: Sei Giga does not use reth or geth, but instead adopts a completely from-scratch EVM client, enhancing performance and efficiency.
· Asynchronous state commitment: Sei removes state commitment from the critical path by generating it asynchronously, rather than as part of consensus.
Jay Jog, co-founder of Sei Labs, stated: "Sei Giga is more than just another EVM chain; it's a reimagining of blockchain performance possibilities. By adopting multi-proposer consensus and rebuilding the execution environment from scratch, we unlock the speed and scale required for real-world high-throughput applications while maintaining Ethereum's trust guarantees and ease of use."
The Sei Giga upgrade introduces a completely redesigned architecture, achieving over 50 times throughput, 70 times block generation speed, and 40 times execution efficiency, while retaining the Proof-of-Stake trust model and providing EVM compatibility. For developers, researchers, and applications seeking to meet modern web application performance requirements, Sei Giga is a definitive step forward.
