Ethlabs Pushes Ethereum's Post-Quantum Roadmap Forward to 2027

Ethereum research group Ethlabs will pull its Quick Slots proposal from the Hegotá upgrade and put its resources into pqai27, a roadmap to make Ethereum post-quantum and post-AI by 2027. The group set out the plan in a post on Ethereum Magicians dated 11 November, written after a week with core developers at Devcon.

"We will withdraw quick slots from Hegotá and commit to dedicating our resources to pqai27," Ethlabs wrote, adding that pqai27 "means rethinking upcoming hardforks, including Hegotá: anything not on the critical path to pqai should be reconsidered."

• The news: Ethlabs will drop its own Quick Slots proposal from the Hegotá upgrade and redirect that work to pqai27, which targets post-quantum and post-AI readiness in 2027.
• The figure: The Ethereum Foundation's published roadmap, dated 7 September 2026, still targets quantum resistance across Ethereum's execution, consensus and data layers by December 2029.
• What happens next: Core developers have not signed off on the reshuffle, and the foundation will reassess quantum progress with outside experts in January 2027.

Quick Slots Out, Frames Stays In

Quick Slots was Ethlabs' proposal to speed up Ethereum's block production, filed as EIP-8198 in Hegotá's scoping list. The group now says it will chase faster slots in 2028 instead, and it did not call the retreat painless.

"We pushed for quick slots because our survey showed that the community clearly wants them, and we are ready to defend this decision to the people who trusted us to deliver them," Ethlabs wrote. "We continue to believe in quick slots and will work towards quicker slots in 2028."

Frames, already the Hegotá headliner, stays. Ethlabs says it sits on the critical path to pqai27, and sketches the fork's execution-layer plan as Frames with a post-quantum signature scheme, SPHINCS, plus post-quantum account EIPs. Without FOCIL, it argues, none of those changes depend on the consensus layer, so the execution layer could ship them without waiting for post-quantum consensus.

FOCIL is the conditional item. Ethlabs says the censorship-resistance feature should proceed only if it does not jeopardise quantum readiness, and it questions FOCIL's practical compatibility with EIP-8288 or with a post-quantum version of Gasper, Ethereum's current consensus protocol. Glamsterdam, the upgrade before Hegotá, should go ahead as planned.

The Outside Timelines Ethlabs Is Reading

The case for 2027 rests on other people's deadlines, not on an Ethereum benchmark. Ethlabs notes the US government moved its goal for handling quantum risk from 2035 to 2030, and that Google now aims to be post-quantum by 2029.

On AI, it points to OpenAI finding and patching about 1,000 vulnerabilities in Linux with its internal frontier model as evidence that capability is accelerating. When FOCIL and Frames were first scoped for Hegotá in January, Ethlabs says, the frontier model was Opus 4.5.

The Foundation's Published Timetable Reads December 2029

Ethlabs' target sits three years ahead of the Ethereum Foundation's own. In protocol priorities published on 7 September 2026, the foundation's Protocol cluster aims for Ethereum L1 to be quantum resistant across execution, consensus and data by December 2029.

The same post says Ethereum L1 should plan for Q-day, the point at which a quantum computer could break current cryptography, as early as 2030, a deliberately aggressive assumption. The foundation said it would treat the deadline as non-negotiable at least until January 2027, when quantum progress is reassessed with outside experts, and that the date lines up with 2029 migration targets set independently by Google, Cloudflare and Microsoft.

Under the July Strawmap, full post-quantum readiness sat at L*, five hardforks after Glamsterdam. A 19 August update added a minimum viable post-quantum milestone at J*. The foundation's own cadence maths has Glamsterdam shipping in December 2026 and L* in December 2029, an average of 7.2 months per fork, with client teams able to begin Hegotá implementation in late Q4 2026. Hegotá scoping drew 62 proposed EIPs.

Ethlabs says the foundation had already moved post-quantum resistance from 2029 to 2028, to leave a margin before quantum computers able to break cryptography arrive at the earliest. That is Ethlabs' account. The foundation's published roadmap still reads December 2029, and no public confirmation of a formal change was found. Ethereum researcher Justin Drake said at Devcon he hopes to complete the transition in 2028, a year earlier than the published target.

The Roadblocks to Ethereum's 2027 Target

Ethlabs names its biggest open question as a post-quantum decoupled consensus versus making Gasper itself post-quantum. It calls converting Gasper plausibly the easier change and says scoping work on pq Gasper has already started.

Two more components are needed for what it calls the at-scale part of the target: signature aggregation under EIP-8288 and post-quantum data availability under EIP-8479. The stretch goal, labelled pqai-scaled, is Ethereum running at full capacity with pqai transactions and blobs, including the scale enabled after Glamsterdam, in 2027.

No decision by core developers has been recorded, so the reshuffle is a proposal on a research forum, not a schedule. By the end of 2028 Ethlabs wants Ethereum post-quantum, post-AI, faster, more censorship resistant and more useful to its growing set of users.

The dated checkpoints that would move the timeline are a core developer decision on what stays in Hegotá and the foundation's January 2027 reassessment of quantum progress.
