A [targeted ACDC](/concept/acdc) is an Authentic Chained Data Container that contains an explicit Issuee field in either its attribute section or attribute aggregate section, binding the credential to a specific entity identifier and making it a directed credential rather than a bearer credential.
A targeted ACDC is an ACDC (Authentic Chained Data Container) that includes an explicit Issuee field within either:
a), orA)This structural characteristic distinguishes targeted ACDCs from untargeted ACDCs, which lack an Issuee field entirely. The presence of the Issuee field means the credential is explicitly issued to a specific entity identified by an AID (Autonomic Identifier), making it a directed credential rather than a bearer credential.
Targeted ACDCs represent the standard credential issuance pattern where credentials are bound to specific subjects. This binding is fundamental to:
The targeted/untargeted distinction is critical for privacy-preserving disclosure mechanisms:
Targeted ACDCs are essential for ACDC chaining through edge operators:
These operators rely on the presence of the Issuee field to establish verifiable chains of authority in directed acyclic graphs of credentials.
In the IPEX (Issuance and Presentation Exchange) protocol, targeted ACDCs enable:
