Sei Labs Keeps Sedna Privacy Upgrade on Future Sei Giga Roadmap

Sei Labs is keeping Sedna on the future roadmap for the Sei Giga upgrade, with the planned privacy feature designed to limit transaction details exposed before ordering and execution.

Sedna would split transaction payloads into coded fragments and distribute them across proposer lanes. The transaction would be reconstructed after enough fragments are finalized, a design intended to reduce risks associated with front-running, sandwich attacks and transaction censorship.

The feature is listed as “Upgrade Coming Soon,” indicating that Sedna is not yet live on the Sei mainnet. Sei Labs describes the system as a private-mempool upgrade, but not an encrypted mempool that uses a threshold key and waits for a committee to decrypt transactions.

The broader Sei Giga upgrade includes planned changes to execution, storage and consensus. Its roadmap lists targets of 200,000 transactions per second and 250-millisecond finality.

The planned Autobahn testnet is also listed as “Coming Soon.” That stage carries targets of 200,000 transactions per second and 400-millisecond finality, making its finality target slower than the broader Sei Giga objective.

Sedna is planned to go live on Autobahn mainnet after the related upgrades are completed. The rollout therefore depends on the completion of the execution, storage and consensus work outlined in the broader roadmap.
