Ethereum plans to achieve a quantum-safe L1 by 2029, with the Hegotá upgrade roadmap taking shape.

According to The Block, the Ethereum Foundation Protocol Cluster has released a list of EIP ratings for the upcoming Hegotá upgrade, setting December 2029 as the target milestone for achieving full quantum resistance. The two S-tier (mandatory delivery) proposals for the upgrade are: FOCIL (EIP-7805) at the consensus layer, which enhances censorship resistance by requiring validator committees to enforce the inclusion of public mempool transactions; and framework transactions (EIP-8141) at the execution layer, which natively integrates account abstraction, supporting custom signatures, sponsored gas, and batch operations to improve security and quantum resistance. The Ethereum Foundation stated that this timeline aligns with the independent migration targets of Google, Cloudflare, and Microsoft, and the December 2029 deadline will be considered non-negotiable prior to January 2027. Hegotá is not the final quantum-safe fork, but rather a critical milestone determining whether subsequent upgrades can proceed on schedule. From the Q4 2026 Glamsterdam upgrade to December 2029, the average fork cycle is only about 7.2 months, leaving extremely limited execution slack.
