Sei’s Autobahn Vote Clears Quorum, but Ballot Remains Open

Sei’s current design gives one validator the job of building each block; its SIP-6 proposal to replace that model with Autobahn has cleared the voting quorum, according to The Defiant’s report. The ballot remains open, so clearing quorum does not mean the proposal has passed.

The vote clears a participation hurdle for a major change to how Sei orders transactions, but the network has not switched to Autobahn.

How much support does SIP-6 have?

The Defiant reported on Nov. 3 that 1.906 billion SEI supported the proposal, above Sei’s 33.4% quorum requirement. Quorum is the minimum share of bonded tokens that must take part for a vote to be valid.

Sei’s governance record lists the measure as proposal 129, “Autobahn upgrade,” and shows the ballot is still in its voting period. The latest tally available in the record showed about 2.38 billion SEI in support, with no votes against or with veto.

The vote is scheduled to close on Nov. 5 at 21:09 UTC. Holders can continue voting until then, and the final result will depend on the completed ballot.

What would Autobahn change for Sei validators?

Under SIP-6, active validators would each maintain a transaction lane and propose batches concurrently. A rotating, stake-weighted leader would coordinate the ordering of those batches.

The SIP-6 draft says the design separates transaction availability, ordering and execution into overlapping stages. It is intended to reduce reliance on one block builder for including and ordering transactions.

The proposal does not promise that censorship or transaction-ordering advantages will disappear. The draft says Autobahn does not eliminate maximal extractable value, or MEV—the gains some actors seek from transaction ordering.

When could the change reach mainnet?

Not immediately after the vote. Sei’s proposal calls for a public testnet and multiple independent security audits before activation, with critical and high-severity issues resolved first.

Until an upgrade is activated, Sei continues to use its current block-building design. The open vote is a governance step toward Autobahn, while testing and security work remain ahead.
