TREE NEWS update: The Ethereum Foundation has set a December 2029 target for making Ethereum’s layer 1 fully quantum-resistant, preparing for the possibility that quantum computers with real attack capability could emerge by 2030. The first test is the Hegotá network upgrade, scheduled for implementation starting late Q4 2026, which includes two S-level EIPs: FOCIL (EIP-7805) and Frame transactions (EIP-8141). The foundation will reassess quantum developments in January 2027, potentially adjusting the timeline.
Ethereum Foundation sets 2029 deadline for post-quantum upgrade
This is notable because it moves quantum resistance from a theoretical concern to a scheduled engineering milestone, with a concrete testnet step in 2026. The January 2027 reassessment is the key checkpoint to watch, as it signals the timeline is provisional and will adapt to actual quantum progress. The choice to bundle FOCIL and frame transactions into the first quantum-focused upgrade suggests the foundation sees these as foundational for the transition. The open question is whether the December 2029 target holds if quantum breakthroughs arrive sooner than anticipated.
