3. Generating the Proof

Calling zkPass Service's generate_zkpass_proof REST API to create the ZkPass Proof

To generate the ZkPass Proof, the Data Holder needs to use the zkpass-client SDK library. The following section illustrates how the coding is done.

Dvr Module Client Integration

The zkPass call sequence diagram, specifically steps 7–9, corresponds to the proof generation process.

The Data Holder generates the proof by using the Dvr module client SDK library, as shown here.

// Step 1: Instantiate DvrModuleClient
const dvrModuleClient = new DvrModuleClient({
      baseUrl: SERVICE_URL,
      apiKey: API_KEY,
      secretApiKey: API_SECRET,
    });

// Step 2: Call the DVR module client's callDvrGenerateZkPassProof
const zkPassProof = dvrModuleClient.callDvrGenerateZkPassProof(
      JSON.stringify(userDataToken),
      dvrToken
    );
