Ethlabs proposes quantum-resistant Ethereum accounts in 2027, at a higher fee

Ethereum research group Ethlabs has proposed a route to quantum-resistant accounts before the network can process such transactions at full scale. Early adopters would pay more because the transactions take up more space, and users would still need wallet support and migration.

Ethlabs proposed on Nov. 11 that users get access to quantum-resistant accounts ahead of full-capacity support. The catch: their quantum-enabled transactions would cost more than ordinary transactions because they take up more space.

Ethlabs offers no fee estimate, and the plan remains a proposal.

Two stages target 2027

The proposal, called pqai27, targets readiness for quantum-resistant accounts and consensus in 2027. Full-capacity support is a stretch goal for that year.

At "pqai-ready," Ethereum would have post-quantum consensus and every user would have a post-quantum route for their account. At "pqai-scaled," it would support full-capacity quantum-enabled transactions and blobs, the data objects used by rollups.

Signature aggregation and post-quantum data availability would provide the later path to full scale. Ethlabs also offers rollups an optional fallback to calldata from quantum-enabled transactions, and says it would carry a higher inclusion cost. The plan does not require rollups to switch.

Wallets and users carry the migration work

Ethlabs places an orderly user migration outside the network upgrade schedule, including tooling and wallet support. Protocol readiness would therefore leave practical work for wallets and users.

Draft EIP-8141, known as Frame Transactions, provides part of the proposed foundation. It would let account code define how transactions are validated and how gas is paid, creating a native route away from today's elliptic-curve signatures and supporting key rotation.

Ethlabs' plan pairs Frames with the SPHINCS post-quantum signature scheme and other account proposals. Upgrading consensus remains a separate, substantial task, and the choice of design is unresolved.

Ethlabs also says it will withdraw its Quick Slots proposal for faster slots from Hegotá and redirect its resources toward pqai27.
