EPCIS and its Role in Improving Supply Chain Traceability for Food and Beverages

EPCIS 2.0 is the GS1 standard for supply-chain event data, and epcis.dev is a capture gateway for it: post an event and the door validates it against GS1's own schema, stamps the capturing account — capturedBy, the warrantor, kept distinct from who, the attested observer — hashes it by CBV 2.0, and appends. That is the ground the topic above stands on.

The concrete gain is evidentiary, not cosmetic. Events validated at capture cannot drift from the standard; the CBV §8.9 hash makes a duplicate the same event and an edit a different one; and an append-only store means the answer to a later dispute, recall or audit is a chain of records that nobody — including the operator — could rewrite. The cost that disappears is the reconciliation meeting.

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.

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.
