Sei Giga: the next-generation architecture
Designed to be the first Multi-Proposer EVM Layer 1 Sei Giga will be the next generation of the Sei protocol following the Giga Upgrade. It will arrive as in-place upgrades to the live network. Every validator will propose concurrently, consensus will finalize only the transaction order, and execution will run asynchronously. On an internal devnet this architecture sustained more than 5 gigagas per second (200,000+ TPS) with ordering finality under 250 ms.Autobahn Consensus
Multi-Proposer BFT: per-validator lanes, 1.5 round trips, sub-250 ms ordering finality.
Async Execution
Consensus will fix ordering; execution and state attestation will follow off the critical path.
Parallel Execution
Block-STM-style optimistic concurrency across all CPU cores.
