Delegus

Signature check

Anyone can check a receipt is genuine.

Delegus signs every decision it makes. Take the receipt, work out its fingerprint, and test it against the public key. Change a single character and the key no longer fits.

    What is real here. The fingerprint and the signature check run for real in your browser, with SHA-256 and Ed25519. The key is an example made just now on this page, and the companies are examples. The lock is a picture of what the maths does. A real receipt is checked the same way against the key Delegus publishes at delegus.ai/.well-known/did.json.

    Check a real receipt

    Paste any Delegus receipt, or get a fresh one from the public sandbox. This one is checked against the key Delegus actually publishes, not an example.
