Ethereum targets quantum‑safe layer‑1 by 2029, Hegotá upgrade outlined
Ethereum sets 2029 deadline for quantum‑safe network
The Ethereum Foundation announced that it aims to make its layer‑1 blockchain resistant to attacks from future quantum computers by December 2029. The plan is tied to the upcoming Hegotá upgrade, which will introduce several critical protocol changes.
Key points
- 62 Ethereum Improvement Proposals (EIPs) were evaluated for the Hegotá upgrade.
- Two proposals received “must‑ship” status (S‑tier): FOCIL (EIP‑7805) for censorship resistance and Frame Transactions (EIP‑8141) for native account abstraction.
- EF Protocol’s “north star” is full quantum resistance across execution, consensus, and data layers by December 2029.
- The timeline aligns with independent migration targets from Google, Cloudflare, and Microsoft.
- Progress will be reassessed in January 2027 with input from external quantum‑security experts.
Confirmed details
The Foundation’s protocol cluster published a tier list that ranks 62 EIPs for the Hegotá upgrade. The S‑tier items are:
- FOCIL (EIP‑7805) – a consensus‑layer change that lets a validator committee force inclusion of valid transactions from the public mempool, reducing the chance a single builder can censor traffic.
- Frame Transactions (EIP‑8141) – an execution‑layer change that splits a transaction into programmable “frames” for validation, gas payment, and execution, enabling custom signatures, sponsored gas, and batched actions without relying on off‑chain operators.
Additional A‑tier proposals (e.g., VOPS Profiles for FOCIL eligibility, Keyed Nonces and Recent Roots for Frame Transactions) will be shipped alongside the headliners unless a cut is required.
Open questions
The Foundation calls the December 2029 deadline “non‑negotiable” until January 2027, after which it will review quantum‑computing progress with outside experts. It acknowledges that many credible estimates place the actual “Q‑day” (the moment quantum attacks become feasible) later than 2030, but a precise date remains uncertain.
Why it matters
Quantum computers could eventually break the cryptographic algorithms that protect blockchain wallets and transactions. By planning for post‑quantum security now, Ethereum aims to preserve the safety of user funds and the network’s integrity for decades to come.
Next steps
The Hegotá upgrade is scheduled to be shipped after the Glamsterdam fork in Q4 2026. Research on future forks (named J* and L*) that will deliver full quantum resistance will continue in parallel. The Foundation will monitor quantum‑security developments and may adjust the roadmap after the January 2027 review.
