Ethereum's Protocol Cluster has committed to making the network's execution, consensus and data layers quantum-resistant by December 2029, using a hypothetical Q-day in 2030 as a planning stress test rather than a forecast. The self-imposed deadline will remain non-negotiable until outside specialists reassess quantum-computing progress in January 2027. Hegota, expected after Glamsterdam's late-2026 launch, is the roadmap's scope gate rather than a post-quantum upgrade itself. The Ethereum Foundation ranked 62 proposed EIPs and designated only EIP-7805, or FOCIL, and EIP-8141, or Frame Transactions, as mandatory. If either encounters technical problems, the Hegota schedule will be delayed instead of removing the proposal. Frame Transactions would establish native account abstraction, allowing individual wallets to adopt new authentication methods without requiring a simultaneous network-wide migration. Ethereum currently relies on ECDSA signatures using secp256k1, exposing a public key when an address transacts and creating a theoretical risk if quantum computers become capable of breaking that cryptography. The roadmap assumes five sequential upgrades at an average 7.2-month cadence, with J* providing an interim post-quantum safeguard before full protection at L* in December 2029.
