👥DVR Client Roles

The DVR follows a robust trust model inspired by the W3C Decentralized Identifiers (DID) standards. Within the zkPass ecosystem, we define three client roles which participate in the zkPass ecosystem.

Depending on the application, the client of DVR can take one of these roles:

1. Data Issuer The entity responsible for issuing the original data that requires protection.

2. Data Holder (User) The individual whose confidential data is being protected.

3. Proof Verifier The service or application that sets the requirements or conditions on the user data. It verifies the zero-knowledge proof, which contains the result of the requirements.

This multi-faceted trust model allows the proper flow of data and communications among the DVR stakeholder clients and ensures that the user’s confidential information remains protected and secure.
