Issue tamper-proof verification reports. Clients can verify authenticity instantly.
Issue digital degrees and transcripts. Students own their credentials forever.
Issue professional certifications (CPA, CFA, etc.) with revocation support.
Issue licenses, permits, and official documents with cryptographic proof.
Anyone can edit a PDF. Your clients spend hours manually verifying documents you issued. Fraud is rampant.
You issued a certificate. Student dropped out. You can't revoke it. They use it forever. No enforcement.
Employers call you daily to verify credentials. You waste staff time answering the same questions.
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.
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).
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.
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.
Student expelled? Certificate issued by mistake? Revoke it via API or dashboard. All future verifications will show revoked=true. This is enforced, not theater.
RESTful API to issue credentials. Integrate with your existing systems. Bulk issuance supported.
Ed25519 signatures on every credential. Tamper-proof. Verifiable by anyone.
Revoke credentials via API. All future verifications show revocation status.
No manual verification requests. Employers verify via API in 5 seconds.
See all issued credentials, verification requests, and revocations in one dashboard.
Full compliance with India's data protection law. Audit trails, consent receipts.
