- Ethereum Foundation targets quantum resistance across execution, consensus and data layers by December 2029.
- The Hegotá review gives EIP-7805 and EIP-8141 S-tier status, marking them as proposals that “must ship.”
- Ethereum’s roadmap expands research into privacy, fast finality, state management and zkEVM alongside quantum security.
The Ethereum Foundation has graded 62 proposals for the Hegotá upgrade, putting quantum security at the center of its roadmap. On Sept. 7, the Protocol Cluster ranked EIP-7805 and EIP-8141 in the S tier, while setting December 2029 as the target for quantum resistance across Ethereum’s execution, consensus and data layers. The assessment involved roughly 60 contributors.
Hegotá Ranking Narrows the Upgrade Scope
The Protocol Cluster published its Hegotá ranking alongside its protocol priorities on Sept. 7. Nine Protocol teams and experts produced 397 grades across 62 proposals. EIP-7805, known as FOCIL, and EIP-8141, known as Frame Transactions, received S-tier status.
S means “must ship,” while A means “expected to ship.” Fifteen proposals received A grades, eight received B grades, and seven received C grades. Meanwhile, the cluster declined 28 proposals, while two remained pending until mainnet evidence becomes available.
Quantum Target Runs Through 2029
The Foundation wants Ethereum’s execution, consensus and data layers to reach quantum resistance by December 2029. It plans that work across several upgrades. The Protocol Cluster said Ethereum should prepare for Q-day as early as 2030.
However, it noted that credible estimates place that threat later, and its arrival remains uncertain. Google, Cloudflare and Microsoft have also set 2029 migration targets. The Foundation will keep its deadline until a January 2027 review with outside experts.
Full post-quantum readiness sits at L*, five forks after Glamsterdam. That schedule requires an average fork cadence of 7.2 months. A minimum viable post-quantum milestone could arrive at J* with a 12-month cadence.
Privacy And Research Priorities Expand
The cluster identified five research areas: fast finality, post-quantum security, privacy, state management and zkEVM. It also said Hegotá should begin work on native, trustless and censorship-resistant private transactions.
Vitalik Buterin has discussed replacing vulnerable BLS signatures. The Foundation’s plan also links account abstraction with EIP-8141. Client teams could begin Hegotá implementation in late Q4 2026.
Geth will publish its list, according to the cluster. The Protocol Cluster will hold a Reddit AMA on Sept. 16 at 2 p.m. UTC. Researchers will discuss Hegotá priorities, the tier list and questions.
