How It Works
1
Capture
Every AI output gets a cryptographic receipt with input/output hashes, model ID, provider, and timestamp.
2
Sign
The receipt is Ed25519-signed by the issuing hub. The public key is embedded in the receipt itself (JWK).
3
Verify
Anyone can verify the receipt's authenticity without trusting any server — all verification material is self-contained.
Receipts follow the W3C Verifiable Credential Data Model (JSON-LD). Signatures use Ed25519. Optional TEE attestation proves execution in a trusted enclave.
