Sample proof facts

Sample PDFs are public static examples, not live proof bundles. Live proof bundles stay tied to a dataset and date, and they become available only after readiness checks pass. See what the signed proof PDF contains.

From sample to your own proof workflow

  1. 1. Inspect a sample. Review the layout and proof fields.
  2. 2. See the public check. Verify a document id and payload hash.
  3. 3. Start your workflow. Use an account to open ready proof bundles.
