Sei Stakers Pass SIP-6 Autobahn Vote at 57.85% Turnout

Zero No Votes, 2.36 Billion SEI in Favor

Sei stakers approved SIP-6, the technical proposal that will replace the network's consensus mechanism with a design called Autobahn, in an on-chain governance vote confirmed on Friday, November 6. The Sei price slipped about 7.6% over the last 24 hours in spot trading, a decline logged over the same window as the vote count. Voting records on Seistream, the network's public block explorer, show proposal number 129 closing with turnout of 57.85%, well above the 33.4% quorum the protocol sets. Participation in a Sei ballot measures the share of staked, vote-carrying SEI that was actually cast. Roughly 2,359,590,000 SEI backed the proposal and 4,751 SEI abstained; the no column and the veto column both read zero. The abstention total, just 4,751 SEI, underlines how few large stakers sat the vote out. Sei announced the ballot in a November 3 post on X that urged staked holders to vote on SIP-6. In substance, SIP-6 asks whether Sei should move away from its current block production model, in which a single validator proposes the set of transactions for each block in turn. That concentration gives whichever proposer is up one decisive say over what enters the block it builds. Under Autobahn, all 40 Sei validators propose candidate blocks in parallel along their own routes, and the validators then converge on one transaction order by following a common set of rules rather than any single participant's preference. Sei presents the switch as a way to cut the risk that a proposer deliberately excludes transactions and to lift how much throughput the chain can absorb. The design also aims to compress part of the MEV, the value extracted by reordering transactions inside a block, by fixing one shared ordering rule set.

Sei Giga Targets 200,000 TPS

Autobahn is a component of Sei Giga, the upgrade program at the center of the Sei roadmap for its next performance phase. On the public testnet, the target is 200,000 transactions per second, capacity Sei frames for DApps and workloads that depend on fast, predictable finality. The project's official technical documentation adds an internal benchmark: in testing, the transaction order was finalized in under 250 milliseconds, with the execution result settling afterward by design. Ordering first, execution second, is the sequencing Sei presents as the source of that speed. The documentation also spells out why the ordering stage is separate: a firm sequence can be locked in quickly even while execution continues, which the team describes as the property that lets throughput scale without giving up determinism. That distinction matters for applications that need to know, within a fixed window, where their transaction sits in a block. The 40-validator set is the group that would run the new proposal paths, meaning the operating burden of block proposal spreads across the full active set rather than rotating one proposer at a time. Passing the vote does not clear the path to mainnet on its own. What token holders approved on November 6 is the technical direction; a separate governance vote must still approve the software upgrade that carries Autobahn onto the live network. Before that can happen, the change has to survive verification on the public testnet and security audits by multiple independent audit firms, with every finding rated high severity or above resolved. The plan also presumes completion of SIP-3, the phased retirement of Cosmos-format transactions and CosmWasm support. As of November 6, Sei had published no date for the mainnet deployment, which leaves the gap between design approval and live rollout open-ended.

The vote record itself is the cleanest part of this story: 2,359,590,000 SEI in favor, zero against, and turnout at 57.85%, some 24 points clear of the 33.4% quorum. Holders treated Autobahn as infrastructure, not ideology, and the contested ground has moved downstream to the audit calendar and the SIP-3 migration, where findings rated high or worse could still push the schedule. That deployment risk, not design risk, is what SEI technical analysis and stakeholders should watch next, alongside the network's existing load: on-chain tracking counted 2,511 addresses holding $291 million in tokenized assets on Sei, the kind of throughput-sensitive activity the upgrade targets. Through the audit window, standard DYOR discipline applies, since a passed vote guarantees nothing about the final code.
