Ethereum Researchers Prioritize Quantum Security Ahead of 2027 Target

Key Points

• Ethlabs is withdrawing its support for the Quick Slots proposal from Ethereum’s planned Hegotá upgrade to redirect development resources toward quantum security.

• Its proposed pqai27 roadmap aims to prepare Ethereum against quantum computing and increasingly capable artificial intelligence threats by 2027.

• The proposal has not been approved by Ethereum core developers, while existing roadmaps place the network’s quantum-resistant transition between 2028 and 2029.

Ethlabs Shifts Ethereum’s Development Priorities

Ethereum research group Ethlabs is proposing a change in the network’s development priorities, urging core developers to focus on quantum resistance ahead of a targeted 2027 readiness timeline.

On Wednesday, the group announced its proposed pqai27 roadmap, which aims to strengthen Ethereum against potential threats from quantum computing and increasingly capable artificial intelligence. As part of the initiative, Ethlabs said it would withdraw its proposal to accelerate block production from the upcoming Hegotá upgrade.

The decision marks a shift from the group’s previous support for Ethereum Improvement Proposal (EIP)-8198, known as Quick Slots. The proposal initially aimed to reduce Ethereum’s block slot time from 12 seconds to 10 seconds.

Ethlabs said it would redirect development resources toward quantum readiness while continuing to pursue faster block production in 2028.

The proposed timeline reflects the group’s view that preparing Ethereum’s cryptographic infrastructure for future computing threats should take priority over unrelated network improvements.

Hegotá Upgrade Faces Potential Changes

Ethlabs also outlined conditions for other features planned for the Hegotá upgrade.

The group said FOCIL, a proposed censorship-resistance feature, should proceed only if its implementation does not compromise quantum readiness.

It also identified Frame Transactions as a central component of the proposed transition. The feature is designed to enable more flexible account authentication, which Ethlabs considers important to Ethereum’s broader security roadmap.

Meanwhile, the group said Glamsterdam, the upgrade scheduled before Hegotá, should proceed according to its existing plan.

These recommendations could influence development discussions, although they do not represent an approved change to Ethereum’s upgrade schedule. Core developers have not formally accepted the pqai27 proposal.

Ethereum’s Quantum Resistance Timeline Remains Unsettled

The proposed 2027 target is more aggressive than the timeline outlined in the Ethereum Foundation’s published protocol priorities.

The foundation’s roadmap, published in September 2026, still identifies December 2029 as the target for achieving quantum resistance.

At Devcon, Ethereum researcher Justin Drake expressed hope that the transition could be completed in 2028, placing his preferred timeline between the foundation’s existing target and Ethlabs’ proposed schedule.

The differing timelines illustrate the ongoing discussion within the Ethereum ecosystem about how quickly the network should prepare for advances in quantum computing.

Although large-scale quantum computers capable of breaking widely used cryptographic systems are not established in the source material as an immediate threat, preparing blockchain infrastructure for potential future attacks involves substantial research and development.

Security Priorities Could Shape Ethereum’s Next Upgrades

Ethlabs’ proposal highlights a broader question for Ethereum developers: how to balance near-term performance improvements with longer-term security requirements.

Reducing block times could improve transaction processing efficiency, while quantum-resistant infrastructure would address a different category of potential risk involving cryptographic security and account protection.

By withdrawing Quick Slots from the Hegotá proposal, Ethlabs is signaling that it considers the quantum transition a higher development priority for the coming years.

The next step will depend on discussions among Ethereum core developers and whether they adopt elements of the pqai27 roadmap. Until formal decisions are made, the proposed 2027 target remains an initiative from Ethlabs rather than an established network-wide commitment.
