Drake Hopes to Complete Ethereum’s Post-Quantum Transition by December 2028
Key Facts
Ethereum researcher Justin Drake said he hopes the network will complete its full post-quantum and post-AI transition by December 2028. Cointelegraph, via TradingView, quoted Drake as saying developers have 24 months to deliver three more network upgrades. That target is faster than the date sought by the Ethereum Foundation’s Protocols team, though the Foundation has not announced it as an official network deadline. The Foundation aims to make all three layers—execution, consensus and data—quantum-resistant by December 2029. The gap between the dates reflects the challenge of accelerating the technical work and coordinating the upgrades.
Drake framed the date as a hope for completing the transition, while the Foundation describes December 2029 as a self-imposed deadline for its Protocols team. The Foundation’s goal covers quantum resistance at the Ethereum layer 1 level across the execution, consensus and data layers. Drake’s proposal therefore does not mean the Foundation has changed its roadmap or adopted December 2028 as the network deadline. The transition involves multiple upgrades: the report said developers need three more upgrades within 24 months. The Foundation says reaching full readiness at its final milestone requires five hard forks after Glamsterdam.
The Foundation’s roadmap stages place a quantum-resistant public-key registry at milestone I*. Milestone G* includes a consensus-layer heartbeat, Lean DA sampling for the data layer, and Lean SPHINCS+ signatures for the execution layer. The Foundation describes this milestone as the minimum viable post-quantum implementation, not full protection across all three layers. The package is designed to keep Ethereum running through Q-day, but with reduced guarantees. The Foundation said researchers are still defining what that reduction in guarantees will look like, while the goal of full quantum resistance remains tied to the December 2029 deadline.
The official timeline depends on a rapid pace of forks: the Foundation says the move from Glamsterdam in December 2026 to milestone L* in December 2029 requires an average of 7.2 months per fork. The span covers five hard forks, according to the Foundation’s presentation of its roadmap to full post-quantum readiness. The Foundation said releasing forks one by one would not be enough to meet the December 2029 schedule. Execution, it said, requires overlapping work and coordination among client teams, researchers, universities and the broader community. That makes meeting the deadline dependent both on technical progress and on completing work in parallel.
The Foundation includes the possibility of Q-day arriving as early as 2030 in its planning assumptions for Ethereum layer 1. But it said most credible estimates point to a later date, or suggest Q-day may never occur. In this context, the Foundation said its self-imposed 2029 deadline will remain non-negotiable at least until January 2027. It will then reassess quantum-computing progress with guidance from outside experts. The Devcon 8 program lists a session by Drake on Ethereum layer 1’s post-quantum roadmap on November 4, 2026, from 12:30 to 12:55.
Ethereum’s page identifies four technical areas requiring post-quantum upgrades: consensus signatures, data-availability commitments, account signatures and zero-knowledge proof systems. The page cited research published by Google Quantum AI in March 2026, which estimated that breaking the 256-bit elliptic-curve cryptography used for account signatures could require about 1,200 logical qubits. The page said current quantum computers cannot break Ethereum’s cryptography and that the work is preparation for the future, not a response to an active threat. For broader standards, the U.S. National Institute of Standards and Technology finalized three post-quantum cryptography standards in August 2024, including a key-encapsulation mechanism and two digital-signature standards. The Foundation also said its 2029 goal aligns with post-quantum cryptography migration targets set independently by Google, Cloudflare and Microsoft.
