About this demo
This is a guided demonstration of a wine supply chain, not a live marketplace. Here is exactly what is real in it and what is not.
What is real
Credential structure
Every record is a real ACDC — the credential format from the Trust Over IP standards work — with attributes, edges and a schema reference.
Identifiers (SAIDs)
Each credential's identifier is a Blake3 digest of its own contents. The X-Ray panel recomputes it live and shows you both values.
Chain linkage
Hand-offs really do point back at the record before them, and each link is resolved against the database when you check it.
Revocation
Withdrawing a credential really does propagate downstream — a consumer's open page flips to an alert.
Selective disclosure
What each party sees is computed by the disclosure engine from their tier. The withheld fields are absent from the response, not hidden by the page.
What is simulated
Issuer signatures & key state
Simulated in this demo — live verification arrives with KERIA integration (Phase 1). Nothing here verifies a signer's key history yet, and the X-Ray panel says so in amber rather than showing a green tick.
People and businesses
Every party is a demo persona. The organisations, licences and lab reports are synthetic data generated for this walkthrough.
Sign-in
Roles are entered by presenting a seeded demo credential. A production deployment authenticates against a real identity wallet.
In production: In production this runs on KERI identifiers with ACDC credentials held by each party — no shared database and no blockchain required — with optional anchoring to Cardano for high-value records.
