The Ethereum Foundation had already moved its post-quantum target from 2029 to 2028. Now nonprofit R&D lab Ethlabs wants to go further, proposing a "pqai27" plan to make Ethereum post-quantum and plausibly post-AI by 2027 after a week with core developers at Devcon.

The plan has two levels. "pqai-ready" means post-quantum consensus and a post-quantum route for every user account while the network keeps the capacity delivered by Glamsterdam. "pqai-scaled", full capacity with post-quantum transactions and blobs, is the stretch goal for 2027.

Ethlabs says it will withdraw quick slots from the Hegotá hard fork and argues that FOCIL, its consensus-layer headliner, should only be scheduled if pqai27 stays achievable.

The lab cites AI speeding up quantum timelines, maths research and bug discovery at scale. Glamsterdam ships as planned and Frames stays on the critical path, but the proposal still needs core developers to adopt it.
