Preventing credential fraud requires checking the issuer, achievement, proof, dates and status together. A polished certificate, QR code or valid signature alone is not sufficient.
Use an authority–integrity–status checklist
Authority: identify the issuer and confirm its right to award the achievement. Integrity: check the supported proof against the signed data. Status: inspect dates and applicable correction, expiry or revocation information. Record the decision and any exceptions.

Treat a QR code as an access path
A QR code can take a reviewer to a record, but it is not itself proof. Check the destination and actual verification result using the credential verification workflow; do not accept appearance or a familiar logo as authority.

Understand what cryptography does not prove
The W3C verification roles distinguish proof checking from policy decisions. A signature does not independently establish a recipient’s identity, accreditation or the quality of the assessment.

Design controls before issuing
In the institutional lifecycle, separate award approval from issuance permissions. Define correction/status procedures, escalation for suspicious records and continuity for issuer resources. Ask which controls are actually included before promising automation.

Check the credential format
For Open Badges achievement credentials, inspect issuer, achievement and criteria rather than inferring competence from the image. Compatibility with a receiving system should be tested.
Handle verification exceptions
If a credential’s proof validates but the awarding institution cannot be confirmed, do not mark the whole application verified. Escalate the authority question. If a status resource is unavailable, record that uncertainty rather than treating it as valid or revoked.
Train reviewers on evidence, not slogans
Keep an agreed procedure and audit trail for manual decisions. No system can guarantee the absence of fraud; the purpose is to reduce avoidable risk and make unresolved questions explicit.
Plan your next step
Discuss the actual award, evidence and implementation requirements with your institution. Request an institutional demo.
Frequently Asked Questions
Does blockchain automatically stop credential fraud?
No. A proof or ledger entry does not establish issuer authority, sound assessment or recipient identity by itself.
What should we do when verification resources are unavailable?
Record the unresolved dependency and follow the institution’s exception policy. Do not infer a valid or revoked status from an unavailable resource.
