Short answer: On September 8, 2026, markets digested a new Ethereum Foundation roadmap that commits to full Ethereum quantum resistance — across execution, consensus and data — by December 2029. The plan names two must-ship features for the Hegotá upgrade, FOCIL and Frame Transactions, and requires hard forks roughly every seven months, a pace Ethereum has never sustained.
What happened
The Protocol cluster of the Ethereum Foundation (EF), the non-profit that funds much of Ethereum's core research, published two posts on September 7: a statement of current priorities and a tier list of proposals for the Hegotá hard fork. Coverage and trading on September 8 focused on the headline commitment — a quantum-resistant Ethereum layer 1 by December 2029, which the team calls non-negotiable at least until January 2027. Ether (ETH) held up better than bitcoin that day, trading near $2,485, with the announcement cited as one source of support.
- Deadline: December 2029 for post-quantum security on all three layers.
- Pace required: about 7.2 months on average between five hard forks, so work on consecutive upgrades has to overlap.
- Hegotá headliners: EIP-7805 (FOCIL) on the consensus layer and EIP-8141 (Frame Transactions) on the execution layer.
- Review scope: 62 proposals graded by nine teams; 2 marked must-ship, 15 high priority, 28 declined.
Why Ethereum quantum resistance is on the clock
Ethereum accounts are secured by elliptic-curve signatures (ECDSA), and validators sign with BLS signatures. A large enough quantum computer running Shor's algorithm could derive a private key from a public key, and on Ethereum an account's public key becomes visible once it sends a transaction. "Q-day" is the shorthand for the moment such a machine exists.
Nobody knows when that will be, and most forecasts put it later than 2029. The EF's argument is that the timing is outside anyone's control, while migrating a live network worth hundreds of billions of dollars takes years. The 2029 date also lines up with post-quantum migration timelines that large technology firms such as Google, Cloudflare and Microsoft have set for their own systems.
The Hegotá upgrade and the road to 2029
The roadmap runs through a chain of named and placeholder forks. Glamsterdam comes first, penciled in for around December 2026, followed by Hegotá and then forks designated I*, J*, K* and L*.
| Fork | Main post-quantum or related work |
|---|---|
| Glamsterdam | Starts the sequence; targeted around December 2026 |
| Hegotá | FOCIL, Frame Transactions, retirement of BLS withdrawal credentials (EIP-8365) |
| I* | Post-quantum public-key registry |
| J* | Post-quantum transactions (hash-based signatures); fallback "minimum viable" quantum safety |
| K* / L* | Lean consensus and mandatory zkEVM execution proofs; full readiness by December 2029 |
The two Hegotá headliners do different jobs:
- FOCIL (fork-choice enforced inclusion lists) lets committees of validators name transactions that a block must include. If a builder leaves them out, attesters refuse to back the block. It is a censorship-resistance measure rather than a quantum one.
- Frame Transactions bring native account abstraction: an account can define its own verification logic. That is the hook for quantum safety, because it lets users switch to a new signature scheme without abandoning their address.
The EF also describes a fallback. If the full schedule slips, a "minimum viable post-quantum" milestone at fork J* would keep Ethereum running through Q-day with weaker guarantees, reachable even with one fork a year after Glamsterdam.
What it means for you
Nothing changes for ETH holders today, and no action is required. No fork in this plan asks users to move funds yet, and dates for later forks are targets, not promises. Two points are still worth keeping in mind.
- Expect a migration step years from now. Once post-quantum signatures are live, wallets will likely prompt users to upgrade accounts. Rely only on announcements from your wallet provider and official Ethereum channels.
- Beware of "quantum-safe upgrade" scams. Any site asking for your seed phrase to "protect" funds from quantum computers is fraudulent — real migrations never need it. Our guide to avoiding crypto scams covers the common patterns.
- Watch fees, not just security. Post-quantum signatures are larger than today's, which can affect transaction sizes; account abstraction and layer 2 networks are meant to absorb that. See how Ethereum gas fees are calculated.
Key takeaways
- The Ethereum Foundation's Protocol cluster set December 2029 as the deadline for a fully quantum-resistant Ethereum layer 1.
- Hegotá's must-ship features are FOCIL (EIP-7805) and Frame Transactions (EIP-8141); 28 of 62 proposals were declined.
- Meeting the date needs five hard forks at an average gap of about 7.2 months, starting with Glamsterdam.
- A fallback "minimum viable" quantum-safety milestone is planned at fork J* if the schedule slips.

Frequently asked questions
When will Ethereum be quantum resistant?
The Ethereum Foundation's Protocol cluster targets December 2029 for full quantum resistance across Ethereum's execution, consensus and data layers. A reduced "minimum viable" level is planned earlier as a fallback.
What is the Hegotá upgrade?
Hegotá is the Ethereum hard fork planned after Glamsterdam. Its must-ship features are FOCIL (EIP-7805), which strengthens censorship resistance, and Frame Transactions (EIP-8141), which add native account abstraction and a path to post-quantum signatures.
Do ETH holders need to do anything about quantum computing now?
No. No migration is required yet. When post-quantum accounts go live, wallets are expected to guide users; anyone asking for a seed phrase to make funds "quantum-safe" is a scammer.
