Overview
- Ethlabs published the pqai27 plan and formally withdrew its Quick Slots proposal from the Hegotá upgrade to reassign engineering effort toward making Ethereum post-quantum and “post-AI” ready by 2027, as reported on November 12, 2026.
- The proposal sets two staged goals: pqai-ready, which would put consensus-level post-quantum protections and account migration tools in place, and pqai-scaled, which would restore full network capacity with post-quantum transactions and data availability.
- Ethlabs identifies concrete technical work that must be done, including EIP-8141 (Frame Transactions) to enable alternative signatures, EIP-8288 for signature aggregation, and EIP-8479 for quantum-resistant data availability, plus possible changes to consensus design.
- The Ethereum Foundation still lists December 2029 as the official network-wide goal and plans an external risk reassessment in January 2027, and core developers have not approved Ethlabs’ accelerated timeline.
- Meeting a 2027 target would force broad coordination across wallets, clients and validators, require migration tools and testing, and could delay or reprioritize noncritical Hegotá features while exposing users and operators to transitional performance trade-offs.
