[Ethereum EIP-8450 Proposal Updated, Proposing Quantum-Resistant Validator Public Key Registration Mechanism] Odaily Planet Daily reports that the EIP-8450 proposal has been updated, proposing to introduce a quantum-resistant public key registration mechanism for Ethereum validators. This mechanism employs a hash-based cryptographic scheme, including leanXMSS keys and a VRF tree root. The update explicitly mandates that registration and replacement of quantum-resistant keys be authorized by the BLS signing key, and sets a replacement delay of at least one epoch and a replay prevention mechanism. This proposal is currently still in the draft stage and has not yet been deployed.
