Three steps to unforgeable
From issuance to verification in seconds.
Issue
Your institution signs each credential with its private Ed25519 key. One at a time or thousands via CSV.
QR on certificate
Every credential carries a QR pointing to its verifiable proof. Print it, email it, embed it.
Instant verification
Anyone scans and sees a stateless cryptographic proof — no account, no database call, no waiting.
Built on open standards
Cryptography, not clerks.
Cachet credentials are W3C Verifiable Credentials signed with Ed25519. Each institution has its own did:web identity. Verification is stateless — the proof is in the signature, not in a lookup.
- W3C Verifiable Credentials — Interoperable, standard-compliant credential format.
- Ed25519 signatures — Fast, modern elliptic-curve cryptography.
- did:web identity — Each tenant is its own verifiable issuer.
- Stateless verification — No central database to trust or breach.
