EU Digital Identity Wallet Requirement by 2026
By the end of 2026, every EU member state must provide citizens with a digital identity wallet. Ontology, which has been running a decentralized identity model on a public chain since 2018, explains how the architecture works. The model involves three roles: issuer, holder, and verifier. The issuer is anyone whose word a verifier will accept, the holder is the person the claim is about, and the verifier is the service that needs to know. Ontology's registry is its public chain, where identifiers, public keys, and the status of credentials are written and can be read by anyone.
