- Timestamped and traceable — issuance date and unique identifier are permanently recorded.
- Authenticated issuer — delivered by a verified organization on the platform, not a homemade document.
- Revocable in real time — a certificate withdrawn by its issuer immediately stops being validated online.
A homemade PDF certificate can be copied in two clicks. Not this one.
