Ethlabs Proposes Pulling Ethereum Quantum and AI Security Deadline Forward to 2027
Ethlabs, an Ethereum research group, proposed on November 11 a plan called pqai27 that would move quantum- and AI-resistance targets to 2027 and withdraw its Quick Slots proposal from the Hegotá upgrade. The Ethereum Foundation's current roadmap targets December 2029, and the proposal still requires agreement from core developers.

The Proposal
Ethlabs published a plan on November 11 on the Ethereum Magicians forum, called pqai27, that would prioritize protection against quantum computing and AI-related security risks in Ethereum's upcoming upgrades. The group wants an initial level of protection in place in 2027, with further work to let the network sustain full capacity afterward. Ethlabs has already committed to withdrawing its Quick Slots proposal from Hegotá, but the wider 2027 plan still needs sign-off from Ethereum's core developers.
Where the Timeline Differs
The Ethereum Foundation's published roadmap currently targets December 2029 for quantum resistance across the execution, consensus and data layers. The Foundation adopted that date while preparing for the possibility that quantum computers could threaten existing cryptography around 2030, and it plans to reassess those risks with outside experts in January 2027. Ethlabs' proposal would therefore advance the deadline by roughly two years. The two sources reviewed describe the gap in the same terms, though neither reports a formal Foundation response to the pqai27 proposal.
Stage One and Stage Two
Ethlabs divides the plan into two stages. The first, pqai-ready, would move Ethereum's consensus system to quantum-resistant cryptography and give users a way to secure their accounts against future quantum attacks. If existing protections became vulnerable, the network could keep running, potentially at reduced capacity. The second, pqai-scaled, would support quantum-resistant transactions and data processing without the same performance limits. Ethlabs described completing that stage during 2027 as an ambitious target.
Trade-offs for Hegotá
Meeting the proposed date would require developers to reshape Hegotá, the major upgrade scheduled after Glamsterdam. Quick Slots, which would reduce the time between Ethereum blocks, is the first casualty. Ethlabs had backed faster blocks in August alongside stronger censorship resistance and improved wallet functionality, and says it still supports faster block production and intends to pursue it in 2028. FOCIL, a proposal that would make it harder for block producers to exclude valid transactions, should be scheduled only if it does not interfere with the quantum deadline, according to Ethlabs. The coverage reviewed does not say whether the Frame Transactions proposal (EIP-8141) faces the same constraint, as that section of the source was cut off.
Stated Rationale and Open Questions
Ethlabs argues that "being post-quantum is not enough, we intend on being post-AI too." Its post-AI approach would rely on cryptography that depends on fewer mathematical assumptions, and on hardening Ethereum's software against vulnerabilities that advanced AI models might find. The group cites Google's goal of completing its post-quantum transition by 2029 and changes in US government planning for quantum-related security risks as context. It also concedes that researchers cannot establish when AI might threaten existing cryptography, or whether certain mathematical attacks will ever become feasible. Its case rests on the argument that this uncertainty makes early preparation necessary.
Why It Matters
For Traders
A proposal to accelerate the schedule and drop Quick Slots is not yet adopted, so the near-term price impact is unclear and any core developer decision is still pending.
For Investors
If core developers adopt an earlier quantum deadline, Ethereum's long-term security posture and the sequencing of its upgrades would shift materially over the next several years.
For Builders
Teams planning around Hegotá features like Quick Slots or FOCIL should watch whether the 2027 deadline is adopted, as it could reorder protocol work and dependencies.
