Digital Product Passports
A public record of what a product is, and what stands behind it.
SourceLoop is a digital product passport platform. A producer publishes a passport for a product line or a lot. Each passport has a stable public address and a QR code. Each claim on it carries a plain-text evidence status. Buyers see what they're buying. Producers see what's said about them. Inspectors see the evidence. Consumers see the chain in their hands.
the separation
Claims and evidence, kept apart.
Most traceability today is a marketing claim wrapped around a database. SourceLoop separates the claim from the evidence and makes the evidence status visible. The L1 to L5 verification ladder is the spine of that separation. Every claim on a passport says what level it stands at. Nothing is rounded up, and no claim gets a tick or a seal.
three decisions
What's different about the system.
We anchor passports to a public proof layer rather than storing them only in a private database. Anyone can confirm that a record exists and hasn't been altered since it was published.
We separate what a producer publishes from what a buyer needs for due diligence. Producers keep control over what's public. Buyers still get the evidence they need for EUDR and similar obligations, behind access they're granted.
We treat the organisations in a chain as first-class records, not metadata. Every cooperative, washing station, processor, exporter and roaster on SourceLoop has its own profile in the registry.
where we are
Coffee and cacao live. Batteries as a prototype.
Coffee passports for arabica and robusta lots from West Java and Sumatra, sourced through Wanoja Farms, and for the ROS Collection lots from Nueva Segovia, Nicaragua. A cacao passport for AYNI in Peru. Active pilot setup in Uganda. The battery passport is a worked prototype against the EU Battery Regulation and says so on every page.
The public layer is free. Verification, private evidence and restricted claims are paid. Pricing sets out the two plans.
