Wu Shuo has learned that the Ethereum community recently proposed ERC-8092, aiming to establish a cross-chain "linked account" identity standard. The proposal is currently in the draft stage and seeks to create a set of standards that allow two blockchain accounts to publicly declare, prove, and revoke their relationship through cryptographic signature payloads. The standard defines the AAR (Associated Account Record) and the SAR (Signed Associated Record), which includes signatures from both parties, providing infrastructure to address friction in multi-address and cross-chain identity management. It supports core use cases such as sub-account identity inheritance, delegated authorization, and reputation aggregation, and achieves interoperability between different chains and cryptographic architectures by being compatible with EIP-7930.
