SEI unveils Giga upgrade roadmap, targets 200,000 TPS and 400ms finality
SEI has announced its Giga upgrade roadmap, aiming for a performance of 200,000 transactions per second and 400ms finality. The upgrade features the Autobahn consensus protocol, which allows for parallel block proposals, significantly enhancing throughput. The rollout is expected in the first half of 2026, with a focus on transitioning to a purely EVM-compatible chain.
- ▪The Giga upgrade aims to push the Sei Network past 200,000 transactions per second with sub-400 millisecond finality.
- ▪The centerpiece of the upgrade is the Autobahn consensus protocol, which enables multiple validators to propose blocks simultaneously.
- ▪Sei's roadmap includes three primary workstreams: execution, consensus, and storage, potentially enhancing EVM throughput by up to 50 times.
