Ethereum Foundation targets quantum-resistant layer 1 by December 2029

The Ethereum Foundation Protocol cluster has established a non-negotiable deadline of December 2029 to secure Ethereum's layer 1 against quantum computing threats. Planning for 'Q-day' as early as 2030, developers are structuring the upcoming Hegotá upgrade around two critical 'must-ship' proposals: FOCIL for censorship resistance and Frame Transactions for native account abstraction. Hitting this timeline requires an aggressive, overlapping hard fork cadence averaging 7.2 months.

Ethereum quantum resistance 2029 deadline

• ▪The Ethereum Foundation Protocol cluster will treat the December 2029 quantum-resistance deadline as non-negotiable until at least January 2027, when it plans to reassess quantum progress with outside experts
• ▪The Ethereum Foundation's December 2029 quantum-resistance timeline aligns with independent migration targets set by Google, Cloudflare, and Microsoft
• ▪The Ethereum Foundation Protocol cluster set a target of December 2029 to make the Ethereum layer 1 base layer quantum-resistant across its execution, consensus, and data layers

Quantum computing threat timeline

• ▪The Ethereum Foundation Protocol cluster advised that Ethereum layer 1 should plan for Q-day—the point when quantum computers can break wallet cryptography—occurring as early as 2030
• ▪According to Project Eleven, approximately 65% of Ethereum currently resides in quantum-vulnerable addresses

Hegotá upgrade EIP tier list

• ▪The Ethereum Foundation Protocol cluster declined 28 proposals for the Hegotá upgrade, including EIP-8363, which proposed tapering issuance and burning the difference
• ▪The Ethereum Foundation Protocol cluster evaluated 62 Ethereum Improvement Proposals for the upcoming Hegotá upgrade, publishing a unified tier list based on 397 grades from nine client teams and individual experts

Frame Transactions native abstraction

• ▪The Ethereum Foundation Protocol cluster rated Frame Transactions (EIP-8141) as an S-tier, must-ship execution-layer proposal for the Hegotá upgrade to make account abstraction native to Ethereum
• ▪Frame Transactions (EIP-8141) splits transactions into programmable frames for validation, gas payment, and execution, allowing wallets to use custom signatures and bypass vulnerable secp256k1 keys

FOCIL censorship resistance proposal

• ▪The Fork-Choice Enforced Inclusion Lists (FOCIL) proposal aims to strengthen censorship resistance by allowing a validator committee to force the inclusion of valid public-mempool transactions
• ▪The Ethereum Foundation Protocol cluster rated Fork-Choice Enforced Inclusion Lists (FOCIL, EIP-7805) as an S-tier, must-ship consensus-layer proposal for the Hegotá upgrade

Post-quantum cryptography migration roadmap

• ▪Under the current draft roadmap, full quantum resistance is targeted five hard forks after Glamsterdam at a placeholder fork named L*, with a minimum-viable milestone at J*
• ▪Reaching full quantum resistance by December 2029 from the Glamsterdam upgrade in late 2026 requires an average cadence of 7.2 months per hard fork, leaving little room for error

Debatable claims

• ▪Ethereum should prioritize its aggressive 2029 quantum-resistance timeline
• ▪Ethereum should implement Fork-Choice Enforced Inclusion Lists to prevent validator censorship
