Ethlabs' Ethereum pqai27 Plan Remains Unratified, Member Says

Ethlabs member Barnabé Monnot has confirmed that the group's pqai27 plan for Ethereum's post-quantum and post-AI security remains a proposal only, with its 2027 priority unconfirmed through the network's governance process. Monnot stated plainly that pqai27 reflects Ethlabs' view and that the parties involved have not all agreed. The admission matters because it distinguishes a single research group's roadmap from a network-wide decision, and Ethereum has no mechanism that converts either into protocol changes without broad developer consent.

The disclosure narrows what had appeared to be a settled direction for the protocol. A plan labeled a priority for 2027 is, on Monnot's account, still awaiting the review that would give it standing.

What did the November meeting actually decide?

According to Monnot, the All Core Devs - Consensus (ACDC) #191 meeting on November 12 discussed the urgency of pursuing pqai27 resistance. Discussion is not adoption. The ACDC format is a coordination call among consensus-layer client teams, and its agenda items routinely fail to translate into hard-fork inclusions. Monnot offered no date for a formal vote and no list of client teams that endorse the plan, which leaves the governance question open.

He characterized the related threats as growing but uncertain. In his telling, AI is accelerating progress on the components needed for pqai27 resistance, and that acceleration is why Ethlabs has elevated the work to its top priority. The claim is directionally plausible but unquantified; Monnot cited no benchmark, no timeline estimate for adversary capability, and no probability assessment. A priority built on an uncertain threat warrants scrutiny of what would trigger de-prioritization, and no such trigger was named.

Which commitments are firm and which are not?

Ethlabs' unconditional commitment, per Monnot, is narrower than the pqai27 agenda itself: the group will withdraw Quick Slots from the Hegotá hard fork. That withdrawal is the one item Monnot framed as settled rather than proposed. The group still plans to pursue quicker slots in 2028, which reframes the change as deferred rather than abandoned. The same proposal calls for reconsidering features that sit outside pqai27's critical path, an instruction that could delay unrelated protocol work if adopted.

The structure of the announcement rewards careful reading. One firm withdrawal, one deferred ambition, and one large security program that remains contested. Stakeholders treating pqai27 as Ethereum's committed 2027 roadmap would be reading more into the statement than Monnot offered.

What happens next?

The plan now passes through Ethereum's governance process, where All Core Devs consensus and client-team implementation decide inclusion. The Hegotá hard fork will proceed without Quick Slots, and the 2028 slot-timing question will resurface after it. Until ACDC participants move from discussing urgency to scheduling specification and client work, pqai27 has a sponsor, a rationale, and no mandate.
