Ethereum co-founder Vitalik Buterin has proposed a timeline to implement quantum-resistant defenses on the Ethereum network by December 2028, ahead of the protocol's existing 2029 roadmap. The initiative aims to secure the blockchain against potential threats posed by advancing quantum computing capabilities. Buterin clarified that this proposal does not represent an agreed-upon upgrade schedule and remains subject to community consensus. Additionally, migrating existing user wallets to the new quantum-safe infrastructure is identified as a separate, distinct task from the core protocol upgrades.
