Proof, not promises.
Most certificates are PDFs that prove attendance. StudAI Loop issues signed evidence containers that anyone can verify in one click — without an account, and without trusting us.
Anatomy of a verified credential
Every public verification page shows the following, in this order — lifecycle first, decoration never.
- Lifecycle status. Issued, revoked, superseded, disputed, or expired — stated before anything else.
- Tamper check. Dual signatures (HMAC-SHA256 + Ed25519) validated against published keys.
- Holder and domain. Who earned it and what course it covers, with the overall mastery score.
- Four-dimensional evidence. Per-chapter recall, transfer, error-recognition, and explanation results.
- Evidence digest. Content-addressed hashes binding the credential to the exact evidence records.
- What it proves / does not prove. Plain-language honesty, including the identity-assurance boundary.
- Offline verification bundle. Everything needed to re-verify the signature with no call to our servers.
Try it yourself
Verification pages are public by design. If you have received a StudAI Loop credential link or QR code, open it — you will see the full evidence trail with no login.
Every learner also gets a public skill passport at /profile/{username} collecting their verified credentials. Earn yours →
Frequently asked questions
- What does a credential prove?
- That the account holder produced mastery evidence across recall, transfer, error recognition, and explanation for every chapter, passed a final exam, and completed a malware-scanned capstone. The per-chapter evidence is attached to the credential itself.
- What does it NOT prove?
- Real-world identity. StudAI Loop does not perform identity verification or proctoring, and every credential says so explicitly. It is honest evidence of account-holder mastery, not a government ID.
- Can a credential be faked?
- A credential is signed with two independent schemes (HMAC-SHA256 and Ed25519). Verification keys are published, and an offline verification bundle lets anyone check the signature without contacting our servers. Tampering with the payload breaks the signatures.
- What if a credential is revoked or disputed?
- The public verification page shows lifecycle status first — issued, revoked, superseded, disputed, or expired. Status changes are visible to anyone holding the link.
