- 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.
Hegotá Ranking Narrows the Upgrade Scope
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
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
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.
