The Ethereum Foundation is targeting a quantum-resistant Layer 1 by December 2029, with its Protocol cluster scoping the Hegotá upgrade around that deadline. Out of 62 proposed changes, only two earned the Foundation's highest must-ship grade, while post-quantum security now sits alongside privacy, faster finality, state management and zkEVM work under tight scope limits.
Ethereum is targeting a quantum-resistant Layer 1 by December 2029, with the Ethereum Foundation's Protocol cluster laying out a multi-fork plan as the Hegotá upgrade enters its scoping phase. Post-quantum security now sits alongside privacy, faster finality, state management and zkEVM development, while the next upgrade faces strict limits on additional scope.
Foundation Grades 62 Proposals, Ships Two
In a post published on September 8, the Ethereum Foundation said roughly 60 researchers, engineers, and domain experts across all nine Protocol teams contributed to a unified assessment of 62 EIPs proposed for Hegotá. Their work produced 397 grades before contested proposals were discussed collectively, but only two proposals received the Foundation's highest must-ship grade.
For Ethereum's core developers, the main target is quantum resistance across the execution, consensus, and data layers by December 2029. That deadline matches migration targets set by Google, Cloudflare and Microsoft, though the timing of "Q-day," when quantum computers could threaten current cryptography, remains uncertain.
Planning Assumptions Stay Aggressive
The Foundation said Ethereum should prepare for Q-day as early as 2030, while acknowledging that credible estimates generally place it later and that it may never arrive. Even so, according to the Ethereum Foundation, the December 2029 deadline will remain "non-negotiable" until at least January 2027, when progress in quantum computing will be reassessed with outside experts.
Under the current roadmap, Glamsterdam is expected in December 2026, while full post-quantum readiness sits at a milestone called L*, five hard forks later. Reaching that target would require an average cadence of 7.2 months. A minimum viable post-quantum milestone at J* could instead be reached with a 12-month cadence.
