Ethereum research group Ethlabs has proposed a route to quantum-resistant accounts ahead of full-scale network support, under a plan dubbed pqai27 that targets post-quantum accounts and consensus readiness in 2027. Unveiled on Nov. 11, the proposal would let users adopt quantum protection earlier, but their quantum-enabled transactions would cost more than ordinary ones because the signatures take up more blockspace. Ethlabs provided no fee estimate. Draft EIP-8141, known as Frame Transactions, forms part of the foundation: it would let account code define how transactions are validated and how gas is paid, creating a native path away from today's elliptic-curve signatures.
Why it matters
Ethereum's account security rests on elliptic-curve signatures that a sufficiently powerful quantum computer could break. The proposal sets two milestones: pqai-ready, meaning post-quantum consensus plus a quantum-resistant route for every user account, and pqai-scaled, adding full-capacity quantum-enabled transactions and blobs, the data objects rollups rely on. Signature aggregation and post-quantum data availability would power the later scale-up, with an optional fallback to calldata carrying quantum transaction data in regular blocks until post-quantum blobs exist.
Market impact
The practical burden falls on wallets and users. Ethlabs places orderly migration, tooling and wallet support outside the network upgrade schedule, so protocol readiness alone will not complete adoption. The plan pairs Frames with the SPHINCS post-quantum signature scheme and other account proposals, while the consensus upgrade itself remains a separate, unresolved task. Ethlabs will withdraw its Quick Slots proposal for faster slots from the Hegotá roadmap and redirect resources toward pqai27. Milestones to watch: wallet migration support, the eventual cost of quantum-enabled transactions, and the aggregation and data upgrades needed to run them at full scale.
Frequently asked questions
-
What is Ethereum's pqai27 proposal?
A Nov. 11 plan by research group Ethlabs targeting quantum-resistant accounts and consensus readiness on Ethereum in 2027, with full-capacity post-quantum transactions and blobs as a stretch goal for that year.
-
Why would early post-quantum transactions cost more?
Quantum-enabled signatures have a larger footprint, so they occupy more blockspace than ordinary transactions. Ethlabs has not provided a fee estimate for the higher cost.
-
What is draft EIP-8141?
Known as Frame Transactions, EIP-8141 would let account code define how transactions are validated and how gas is paid, creating a native route away from elliptic-curve signatures and supporting key rotation.
-
What role does wallet migration play in the plan?
Ethlabs places orderly user migration, including tooling and wallet support, outside the network upgrade schedule. Wallets must add support before adoption is complete, even after protocol readiness is achieved.
-
Which post-quantum signature scheme does the plan use?
The plan pairs Frame Transactions with SPHINCS, a post-quantum signature scheme, alongside other account proposals. The design for upgrading consensus remains unresolved and is treated as a separate task.
