EIP-8450 Update: Post-Quantum Key Registration for Validators Now Authorized Solely by BLS Keys, with No Changes to the Execution Layer

TechFlow news, October 29: According to PR #12592 on ethereum/EIPs on GitHub, developer kevaundray submitted an updated draft of EIP-8450 (post-quantum key registration scheme for Ethereum validators). The draft removes the withdrawal address authorization path, the EIP-7685 request type, the execution layer request contract, and the pending authorization queue. Dependencies are reduced from EIP-7002, EIP-7685, and EIP-7916 to EIP-7916, and the proposal no longer modifies the execution layer. The BLS signing key becomes the sole authorizer, allowing keys to be registered and replaced. The default key change interval is 256 epochs, with a minimum preset of 8 and all presets at least 1.
