- This specification describes discovery and exchange mechanisms, particularly - as they relate to supply chain use cases. The specification extends the core - Verifiable Credential API definitions described in the VC-API specification, - adding cross-security domain interactions. Systems implementing the - traceability-interop specification can exchange Verifiable Credentials over - HTTP within proofed Verifiable Presentations. Exchanged Verifiable - Credentials often implement schemas defined in the traceability-vocab - specification. + This specification describes discovery and exchange mechanisms of [Verifiable + Credentials](https://www.w3.org/TR/vc-data-model-2.0/), particularly as they relate to supply chain use cases. + Exchanged Verifiable Credentials often implement schemas defined in the [Traceability Vocab + Specification](https://w3c-ccg.github.io/traceability-vocab/). +
++ Using Verifiable Credentials to represent supply chain data enables interoperability between disparate actors, + and provides the ability to cryptographically verify the authenticity of the data. +
++ This specification uses the [Decentralized Identifiers (DIDs) v1.0](https://www.w3.org/TR/did-core/) + specification to identify organizations within a supply chain. This enables organizations to interact with parties + outside their traditional supply chains, and removes the need for a central authority to identify supply chain + organizations.
