Ethereum Targets Quantum Resistance by 2029 in New Roadmap Plan

• Ethereum targets quantum resistance across execution, consensus and data layers by December 2029.
• FOCIL and Frame Transactions receive the highest priority in the Protocol Cluster’s Hegotá rankings.
• The cluster will reassess quantum progress with outside experts in January 2027.

Ethereum Foundation’s Protocol Cluster has set December 2029 as its target for a quantum-resistant base layer. Its September 7 publications also rank 62 proposals for the Hegotá upgrade, placing censorship resistance and programmable accounts first.

Together, the posts connect immediate development choices with a longer security timetable. Hegotá would prepare the network for later changes without completing the quantum transition itself.

Ethereum ranks Hegotá proposals around two core changes

About 60 researchers, engineers and specialists contributed to the review across nine teams. The process produced 397 individual ratings, with discussions addressing proposals that divided participants.

FOCIL, or EIP-7805, receives the highest priority on the consensus layer. It would let validators require eligible transactions in blocks, reducing reliance on dominant builders.

Meanwhile, Frame Transactions, EIP-8141, leads the execution-layer rankings. It would make validation, gas payment and execution programmable, giving Ethereum accounts more flexibility over signature methods.

Both proposals receive S-tier status, meaning the cluster would adjust scheduling before dropping either feature. Supporting proposals cover transaction eligibility, keyed nonces and recent state roots.

The rankings express the cluster’s priorities rather than guaranteeing every proposal a mainnet release. Client implementation and testing still determine which changes can ship safely.

Quantum resistance target shapes the next upgrade cycle

For Ethereum, the December 2029 goal covers execution, consensus and data. The cluster plans around quantum attacks becoming possible in 2030, while describing that assumption as deliberately aggressive.

Most credible estimates place that threat later, the post says. Outside experts will help reassess progress in January 2027.

Under one roadmap sequence, full protection follows five forks after Glamsterdam. Shipping those upgrades between December 2026 and December 2029 would require an average interval of 7.2 months.

A separate minimum-viable milestone would provide temporary safeguards with reduced guarantees. Researchers are still defining those limits.

Ethereum development teams must therefore overlap implementation, specifications and research across successive upgrades. The cluster will host a Reddit discussion on September 16 at 14:00 UTC to answer questions about its priorities.
