AI Provenance Verifier

Cryptographic receipts for AI outputs — verify origin without trust.

Verify an AI Provenance Receipt

Paste a receipt ID or the full JSON receipt below. No server needed — verification runs entirely in your browser.

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.
