Sei Giga Upgrade Unveils Multi-Proposer EVM L1, Autobahn Consensus, and Major Performance Boosts

Sei Labs has released a whitepaper introducing Sei Giga, a transformative blockchain upgrade focused on boosting Sei’s performance and scalability as an Ethereum Virtual Machine (EVM) Layer 1 chain. Key technical innovations include asynchronous block execution, multi-proposer consensus via the Autobahn protocol, transaction parallelization, and advanced storage optimization. The Autobahn consensus separates data availability from transaction ordering, allowing multiple validators to propose transaction batches and enabling faster, more efficient block confirmation. Parallel execution processes non-conflicting transactions simultaneously, significantly increasing throughput, with targets of up to 100,000–200,000 transactions per second and sub-400 millisecond finality. Storage enhancements leverage a robust key-value model, layered architecture, and cryptographic accumulators for data security and scalability. Backed by over $30 million from major venture capital firms, Sei positions itself as the first EVM chain to implement multi-proposer support, potentially increasing throughput by up to 50x and execution efficiency by 40x. Analytics show growing on-chain activity with daily active addresses and transactions rising sharply. However, the upgrade introduces risks such as potential network pauses and conflict management challenges. For crypto traders, Sei’s evolution is poised to attract developers and institutions, drive increased trading activity, and strengthen $SEI’s appeal as a high-performance, EVM-compatible blockchain, which could influence its market dynamics.
