1. Retrieving the DVR

Retrieving the Data Verification Request (DVR) from the Proof Verifier

PreviousData HolderNext2. Retrieving the User Data

Last updated 6 months ago

From Data Holder perspective, no integration with the Dvr module client SDK library is needed for this step.

The Data Holder first gets the DVR by calling the provided by the Proof Verifier.

The zkPass call sequence diagram, specifically steps 1–3, corresponds to the DVR retrieval process.
