Giga Sei technical summary: Autobahn, async execution and flat storage
Quote184 words
Summarizes Giga Sei: about 200k TPS and under 400ms finality, Autobahn multi-proposer consensus cutting rounds from about 3 to 1.5, async execution cutting finality latency about 70%, OCC parallel EVM and flat key-value storage.
Key claims
About 200k TPS (5 GigaGas/sec), roughly 50x current top EVM chains
Autobahn consensus takes about 1.5 rounds vs about 3 for Tendermint
Async execution cuts finality latency by about 70%

โ Scales EVM to ~200k TPS (5 GigaGas/sec) with consistent <400ms finality, delivering ~50x higher throughput than current top EVM chains.
โ Autobahn multi-proposer consensus enables parallel block proposals, reducing consensus latency to ~1.5 communication rounds (from ~3 rounds in Tendermint).
โ Fully decoupled asynchronous execution cuts finality latency by ~70%, removing traditional bottlenecks seen in synchronous state commitments.
โ Purpose-built Sei EVM implements Optimistic Concurrency Control (OCC), parallelizing execution (nonce checks, ECDSA recovery, intrinsic gas calculations), resulting in ~50x execution efficiency gains.
โ New flat key-value storage model replaces Merkle trees, using asynchronous cryptographic accumulators for O(1) state updates and reduced storage overhead.
โ Fully compatible with existing Ethereum dApps (Solidity/Vyper), enabling frictionless developer integration.
The Bottom line?
Giga Sei significantly advances EVM scaling, setting new performance standards, and enabling previously unattainable real-time, high-speed blockchain apps across DeFi, gaming, enterprise solutions, and more.
