The conventional identity transaction asks a central provider to confirm who you are each time you sign in. A wallet model changes the architecture: trusted issuers provide credentials, the holder keeps them in a wallet, and the holder presents verifiable claims to a relying party.

Three public developments make this more than a niche technical idea. W3C Verifiable Credentials Data Model 2.0 is a web standard. NIST’s final Digital Identity Guidelines now address subscriber-controlled wallets. And the European Union is implementing a digital identity wallet framework that requires member states to offer wallets by the end of 2026.

Selective disclosure changes the privacy bargain

The most important feature is not storing a digital copy of an identity document. It is proving the minimum claim a transaction requires. A person may need to prove they are over a threshold age without transmitting a full birth date, or prove a professional role without exposing an unrelated identifier.

MoonVault view: sovereignty is not possession alone. It is the ability to choose what is disclosed, to whom, for what purpose, and for how long.

Control still requires governance

A wallet creates a new control point. That makes recovery, device loss, revocation, credential freshness, delegated use, and succession first-class design questions. A credential can be valid while a particular presentation is unauthorized. A holder can control a wallet while still depending on issuers, verifiers, software vendors, and recovery mechanisms.

For MoonVault, the durable opportunity is the coordination layer around the wallet: how authority is expressed, how consent is evidenced, how access is delegated, and how continuity survives a change in device, role, capacity, or principal.
