EPCIS and Traceability: Ensuring Ethical Supply Chain Practices

Start from the record, not the buzzword. An EPCIS 2.0 event is a validated, hashed, appended fact, and epcis.dev is a capture gateway that enforces exactly that: GS1's own schema at the door, the capturing account stamped — capturedBy, the warrantor, kept distinct from who, the attested observer — the CBV 2.0 hash as the event's identity, and no way to un-write. The topic above is read against that record.

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.

Identity is the standard's own. The gateway computes the standardized EPCIS event hash from CBV 2.0 §8.9, with GS1 Digital Link normalization, checked against pinned reference vectors, so the same event captured twice is the same event and a changed event is a different one.
