Ethereum developers propose quantum-safe staking upgrade

Ethereum researchers submitted a draft proposal on Aug. 24 for a post-quantum-ready validator deposit contract that could eventually allow the network to replace its current BLS signature system. Summary Ethereum researchers submitted a draft post-quantum deposit contract proposal for validator signature migrations this week. The design supports variable-length public keys, signature schemes and metadata without selecting a post-quantum algorithm yet. Scheme 0 would preserve current BLS deposits while later identifiers accommodate alternative cryptographic signature systems. An irreversible migration switch could eventually stop new BLS deposits after a staged transition period. The pull request remains a draft awaiting editor consensus, technical review, discussion and successful checks. Kevaundray Wedderburn, Tom Wambsgans and Thomas Coratger authored the proposed core Ethereum Improvement Proposal. The draft remains an unmerged GitHub submission and has not been selected for a network upgrade. Ethereum proposal prepares deposits for new signatures Ethereum validators currently use BLS public keys and signatures with fixed lengths. The proposed contract instead accepts variable-l...
