Who Uses ProofOS as a Verifier?

BGV Agencies

Issue tamper-proof verification reports. Clients can verify authenticity instantly.

Universities

Issue digital degrees and transcripts. Students own their credentials forever.

Certification Bodies

Issue professional certifications (CPA, CFA, etc.) with revocation support.

Government Agencies

Issue licenses, permits, and official documents with cryptographic proof.

Issuing PDFs is Not Enough Anymore

PDFs Are Easy to Fake

Anyone can edit a PDF. Your clients spend hours manually verifying documents you issued. Fraud is rampant.

No Revocation Control

You issued a certificate. Student dropped out. You can't revoke it. They use it forever. No enforcement.

Manual Verification Requests

Employers call you daily to verify credentials. You waste staff time answering the same questions.

No Trust Infrastructure

Your reputation depends on trust, but you have no way to prove authenticity cryptographically.

ProofOS gives you cryptographic proof infrastructure.

Issue credentials. Instant verification. Real revocation. Zero manual work.

How ProofOS Works for Verifiers

1. Issue Cryptographically Signed Credentials

Use our API or dashboard to issue credentials. Each credential is signed with Ed25519 cryptographic signatures and stored in the recipient's ProofOS wallet. You get an issuer key pair (think: your digital signature).

2. Recipients Share Proofs

Recipients (students, employees, etc.) own the credentials in their wallets. They can share proof packages with employers, banks, or anyone who needs to verify. You don't handle this — the recipient does.

3. Instant Verification (No Manual Work)

When someone wants to verify a credential, they use ProofOS verify API. It checks the signature, issuer, and revocation status automatically. No phone calls to you. No manual checks. Instant trust.

4. Revoke When Needed (Actually Works)

Student expelled? Certificate issued by mistake? Revoke it via API or dashboard. All future verifications will show revoked=true. This is enforced, not theater.
