There are a number of identity related Ethereum standards under development, in addition to ERC725 and 735, :
- ERC: Lightweight Identity #1056 —This ERC describes a standard for creating and updating identities with a limited use of blockchain resources. An identity can have an unlimited number of delegates and attributes associated with it. Identity creation is as simple as creating a regular key pair ethereum account, which means that it's fee (no gas costs) and all ethereum accounts are valid identities. Furthermore this ERC is fully DID compliant.
- ERC1056 ❤ ERC780 — an open identity and claims protocol for Ethereum
- EIP-780 Ethereum Claims Registry
- EIP712 - This is a standard for hashing and signing of typed structured data
- ERC-1484 Digital Identity Aggregator —A protocol for aggregating digital identity information that's broadly interoperable with existing, proposed, and hypothetical future digital identity standards.
- EIP-1078 - This presents a method to replace the usual signup/login design pattern with a minimal ethereum native scheme, that doesn’t require passwords, backing up private keys nor typing seed phrases.
- ERC-1077 and ERC-1078: The magic of executable signed messages
