Is Ethereum ready for quantum computers? Here’s the latest progress:
Post-quantum transition target: December 2028 | leanVM: >1,000 leanXMSS aggregations per second
At Devcon 8 Mumbai (Nov 3, 2026), Ethereum Foundation researcher Justin Drake shared an update on the quantum security roadmap. Key points:
1. leanVM passes formal verification — leanVM is a minimalist zkVM that combines many hash-based post-quantum signatures into a single compact proof. Formal verification means its code has been mathematically proven to comply with its specifications, end to end.
2. BLS will be replaced by leanXMSS — Validator signatures on the consensus layer, which currently use BLS, are planned to be replaced with the hash-based leanXMSS scheme. It is built on three open-source projects: leanVM, leanXMSS, and leanSpec.
3. 2028 is still a hope, not a promise — Drake said he hopes the full post-quantum and post-AI transition will be completed by December 2028. The Foundation’s official target (roadmap dated Sep 7) remains December 2029 for all three layers, and quantum progress will be reassessed in January 2027.
