Originally reported November 12, 2026, at 13:21 (UTC+8). Ethlabs proposed making post-quantum and “post-AI” security a top priority for Ethereum protocol development, with a 2027 target it calls pqai27. This is a proposal, not an approved upgrade schedule.
In a post to the Ethereum community forum, the team argued that AI could accelerate the discovery of software vulnerabilities and solutions to mathematical problems, while the timeline for quantum-computing threats may be shortening. It called for cryptography with fewer security assumptions, stronger client security and more formal verification.
Ethlabs suggested reassessing the scope of the planned Hegotá hard fork and reconsidering features outside pqai27’s critical path. It also said it was withdrawing its earlier request for QuickSlots resources for Hegotá and redirecting that effort to pqai27.
Under the preliminary roadmap, Hegotá would introduce post-quantum consensus and account-signature schemes to make Ethereum capable of post-quantum operation. Signature aggregation and post-quantum data-availability work would follow to support operation at full capacity. Ethlabs described becoming “pqai-ready” in 2027 as the primary goal; reaching “pqai-scaled” full capacity is a more challenging stretch goal. The source does not establish that these changes have been accepted or activated.
