A brand new design achieving 5 Gigagas throughput, sub-400 millisecond finality, and 20,000+ TPS, supporting high-performance EVM applications
New York, May 19, 2025 — Sei Labs, the primary contributor to the Sei blockchain, today released the 'Sei Giga Whitepaper', marking a significant step towards the first multi-proposer EVM Layer 1. By introducing a parallel block proposal mechanism to address bottlenecks, Sei Giga aims to expand EVM capabilities through performance innovations in data availability, consensus, execution, and storage.
Sei Giga combines a high-performance consensus mechanism and a from-scratch EVM execution client to overcome traditional blockchain network limitations, achieving significant improvements in transaction throughput, latency, and scalability.
The main features of Sei Giga include:
● < gasput approximately 20 strong optimized scalable high applications.
● Sub-400 millisecond finality: Providing fast transaction confirmation to meet low-latlow--latency, high-performance requirements.
● EVM compatibility: Supporting Ethereum smart contracts (Solidity, Vyper), facilitating integration with Ethereum applications.
● Autobahn consensus protocol: Adopting a multi-proposer architecture that supports parallel block proposals, achieving a 50-fold throughthroughput increase.
● Entirely new execution client: Sei Giga uses a completely from-scratch EVM client, instead of reth or geth, improving performance and efficiency.
● Asynchronous state commitment: Sei Giga separates state commitment generation from the consensus process, processing it asynchronously to avoid becoming a bottleneck in the critical path.
Jay Jog, co-founder of Sei Labs, stated: "Sei Giga is more than just another EVM chain; it redefines the possibilities of blockchain performance. performance. multi-the proposer consensus mechanism and fundamentally restructuring environment we are unlating the scale and speed required speed required to real-world high-throughput applications while maintaining Ethereum, Ethereumees and Eusability."
The Sei Giga upgrade introduces a designed architecture architectural that achieves over 50 times throughput improvement, 70 times faster block generation, and 40 times execution efficiency, while the maintaining the Proof-of-Stake trust model and EVM compatibility. For developers, researchers, and applications seeking to meet modern web application performance requirements' performance seiIga is a definitive step forward.To theaperaper, please visit:
