Ethereum researcher and Ethlabs member Barnabé Monnot said Ethlabs’ proposal for Ethereum to achieve post-quantum and AI security in 2027, known as pqai27, reflects Ethlabs’ own assessment. It has not been confirmed through Ethereum’s governance process, and not all parties agree. By contrast, Monnot described Ethlabs’ pledge to withdraw consideration of quick slots as unconditional. That pledge is not a claim that a network change has been activated.
Monnot said the urgency of advancing pqai resistance was discussed at the November 12 Ethereum All Core Developers Consensus meeting (ACDC #191). In his view, the threats are growing but remain “known unknowns.” He said AI is accelerating progress on key components needed for pqai resistance, which is why Ethlabs currently treats the work as its highest priority.
Foresight News had previously reported that Ethlabs posted the pqai27 proposal on Ethereum Magicians and suggested dropping nonessential features such as quick slots. The 2027 target remains a proposal, not an approved upgrade schedule.
