For Ethereum builders, the proposal raises two questions: how would accounts and validators move to post-quantum keys, and how would client software withstand vulnerability searches conducted at scale with frontier AI models?
In an article published on November 12, 2026, at 12:25 p.m. UTC+8, Ethlabs proposed that Ethereum pursue a “post-quantum and post-AI” goal for 2027, which it calls pqai27. The article argues that AI is accelerating both the quantum-computing timeline and the capacity for network attacks. It calls for pqai to become Ethereum’s highest protocol-level priority.
Ethlabs says that priority would require revisiting the scope of Hegotá: potentially delaying FOCIL while retaining Frames and a post-quantum account EIP. Its proposed sequence is to reach pqai-ready in 2027 before working toward pqai-scaled.
Ethlabs also says it will withdraw its quick slots proposal and redirect resources to pqai27. The work it identifies includes wallet migration, migration of validators to post-quantum keys, client hardening and formal verification. These are proposed priorities, not reported completed migrations or demonstrated protections.
