Harnessing EPCIS for Complete Supply Chain Transparency

The gateway framing matters for this topic: epcis.dev accepts an event only after validating it against GS1's own schema, stamps the capturing account — capturedBy, the warrantor, kept distinct from who, the attested observer — identifies it by its CBV 2.0 hash, and appends it to a store nothing rewrites. What follows stands on those mechanics.

Traceability holds only when the record would hold up out of context: validated at capture against GS1's official schema, identified by the standard's own hash, appended and never edited, with the capturing account stamped by the gateway rather than asserted by the sender. That is what turns a trace from a report someone compiled into evidence someone else can check.

Reads are minimally scoped. You see your own scope; what is outside it is absent, not greyed out and not redacted, so there is no shape left behind to argue about. Recording an event is $0 by policy — intent, until published terms bind it — because a stream that charges per event is one you stop feeding the month the bill grows with volume.

The same door answers people and agents. Capture, query, get_event, trace and translate are exposed over MCP, so a logistics agent captures and queries with the same key a person would use, without a human copying values between two systems.
