Affinidi

Affinidi builds verifiable identity infrastructure, packaging W3C verifiable credentials, decentralised identifiers and encrypted messaging into components an enterprise can deploy. A holder receives a credential signed by an issuer and discloses only the fields a verifier needs, while the verifier queries a trust registry for the current authorisation status of both parties instead of pooling personal data in a central database.

The stack includes did:webvh identifiers with verifiable history, DIDComm v2.1 encrypted channels, the Trust Spanning Protocol and the TRQP trust registry query protocol, with SD-JWT selective disclosure and OID4VCI and OID4VP issuance and presentation flows. Over the past year the focus has shifted to AI agents: Agent Gateway issues an identity and a signed mandate when an agent is created, every call carries that mandate, actions outside the mandate cannot produce a valid signature, and each action writes a content-free receipt that third parties can recheck. The company holds ISO 27001 certification, and its public trust networks carry more than eighteen thousand five hundred signed credentials.
