VNT (Verifiable Node Token) technical details
VNT is a cryptographic proof based on Ed25519 signatures.
When you certify a fact, Certorix:
- Hashes the fact content (Subject + Predicate + Object + timestamp)
- Signs the hash using your organization's Ed25519 private key
- Stores the signature, public key, and timestamp in the VNT token
Customers see a seal containing the token ID, timestamp, and a 'Verify' link. Anyone can verify the fact hasn't changed by re-hashing the content and comparing signatures.
The private key is generated per organization and never leaves Certorix servers.
