How EPCIS is enhancing supply chain agility and responsiveness?

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.

Whatever the setting, the mechanics underneath this topic are the same four moves: an event is captured at a door, validated against GS1's official EPCIS 2.0 schema, identified by the CBV 2.0 §8.9 hash of its own content, and appended to a store nothing can rewrite. The variations between industries and use cases are vocabulary — the CBV's business steps and dispositions — not architecture.

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

Two attributions travel with every event, and the door owns a different half of each. capturedBy is the warrantor — the account whose key opened the door — stamped by the gateway together with recordTime and the attestation grade, with caller-supplied values in those stamped fields stripped. who is the attested observer, asserted by the caller and graded by the door: it reaches only the grade claimed until identity attestation lands. One is stamped, the other is graded; they never merge.

Proof, not adjectives. The gateway's conformance tests pass against GS1's normative artefacts, and the calculators answer on this origin — POST /translate, /validate, /hash, no key. The dated ledger is What ships today.
