Sei Network Approves SIP-6, With Autobahn Mainnet Still Ahead

Sei Network approved SIP-6, advancing the Autobahn consensus upgrade within Sei Giga and clearing a governance hurdle on the path to mainnet. The vote does not activate the upgrade: a public testnet, audits and other rollout work remain, and no mainnet date has been announced. SIP-6 changes how blocks are assembled. Each active validator would keep a separate lane for proposed transactions, allowing validators to package activity concurrently instead of routing it through one producer. Stake weight determines which validator takes the next turn coordinating references to certified batches. The proposal has transaction ordering, data availability and execution proceed in overlapping stages. The design is intended to spread transaction packaging across active validators and use their combined bandwidth, while reducing reliance on one block producer for transaction inclusion and sequencing.
