Ethlabs, a nonprofit lab of former Ethereum Foundation researchers, proposes making Ethereum post-quantum and post-AI in 2027, called pqai27, moving up the current target of full quantum protection by end-2029.
Stage 1, pqai-ready in 2027, is quantum-resistant consensus plus user migration to new cryptography via Frames (EIP-8141), keeping the chain working at reduced throughput even if current algorithms break. Stage 2, pqai-scaled, restores full capacity with post-quantum transactions and blobs, needing signature aggregation and post-quantum data availability, plus formal code verification and client diversity against AI-found bugs.
It would require reprioritizing the Hegota hardfork: Ethlabs withdrew its own Quick Slots block-speedup to 2028, and says FOCIL censorship-resistance (EIP-7805) should not delay the quantum switch if compatibility is too hard. Glamsterdam and scaling plans would stay. The proposal is not approved. It is Ethlabs' view published Nov 11, 2026 after Devcon; the decision rests with core developers.
