presentation exchange

Definition

An exchange that provides disclosure of one or more ACDCs between a Discloser and a Disclosee.

A presentation exchange is the process by which authenticatable information may be exchanged between two parties, namely, the Discloser and Disclosee.

Rule

Each ACDC MUST have an Issuer and MAY have an Issuee. The set of ACDCs so disclosed in a presentation exchange MUST be chained. This set of chained ACDCs define a directed acyclic graph that MUST have at least one vertex and MAY have zero or more edges pointing to other vertices.
