New York - May 19, 2025 - Sei Labs, a major contributor to the Sei blockchain (the most powerful Layer 1 blockchain), today released the Sei Giga white paper. This white paper outlines the development path for the Sei blockchain to become the first multi-proposer EVM Layer 1. Sei Giga addresses bottleneck issues through parallel block proposals and aims to enhance the capabilities of EVM through innovations in data availability, consensus, execution, and storage performance optimization.

By combining a high-performance consensus mechanism with an EVM execution client built from scratch, Sei Giga aims to break through the limitations of traditional blockchain networks, achieving significant improvements in transaction throughput, latency, and scalability. 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 in under 400 milliseconds: Fast transaction confirmation, achieving low latency and high-speed performance.

• EVM compatibility: Supports Ethereum smart contracts (Solidity, Vyper), facilitating integration with Ethereum applications.

• Autobahn consensus protocol: Adopts a multi-proposer architecture, supporting parallel block proposals, achieving a 50-fold increase in throughput.

• Brand new execution client: Sei Giga does not use reth or geth, but instead employs a completely built-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 the consensus.

Jay Jog, co-founder of Sei Labs, stated: "Sei Giga is not just another EVM chain; it is a reimagining of the possibilities of blockchain performance. By adopting multi-proposer consensus and rebuilding the execution environment from the ground up, we unleash the speed and scale required for real-world high-throughput applications while maintaining the trust guarantees and usability of Ethereum."

The Sei Giga upgrade introduces a completely redesigned architecture, achieving over 50 times the throughput, 70 times the block generation speed, and 40 times the execution efficiency, while retaining the trust model of Proof-of-Stake and providing EVM compatibility. For developers, researchers, and applications seeking to meet the performance demands of modern web applications, Sei Giga is a decisive step.
