This document proposes an overview of Digital Identities on the Web and an analysis through different use cases of the systemic impact on both the market side and the human side, as well as the role that Web standardization may play in managing that impact
In 3.3.1.3. Layer 3: Credential Layer, the description of Verifiable Presentation (VP) states: “If Selective Disclosure is adopted, the proof is obtained through the use of a cryptographic zero-knowledge proof.”
In some broader uses of VC suites, it may not fully align with the strict definition of ZKP, but still achieves the functionality of Selective Disclosure (SD). Perhaps it could be revised to: “If Selective Disclosure is adopted, the proof MAY be obtained through the use of a cryptographic zero-knowledge proof.”
Additionally, as per Issue #14, it is understood that different SDOs have varying definitions of VC, so the discussion on the adoption of ZKP in VC under different definitions will not be addressed here, even though this could lead to some differences.
