The page collects summaries of candidate use cases for chained credentials, including the GLEIF (Global Legal Entity Identifier Foundation) vLEI (verifiable Legal Entity Identifier), supply chain provenance, guardianship, delegation, IoT (Internet of Things) device onboarding and consented data provenance, each with the organizations proposing it. It also sketches attribution chaining semantics, in which a chaining statement securely links two attributed statements and the chained statements may convey authorization, delegation, attestation or provenance.

Labels: reading level Practitioner; evidence official (a statute, a regulator's document, or a standards body's own page).
