- commonly used in SSI for selective presentation of credentials or verification of access to a digital asset

Key Concepts
What is zero knowledge proof in Hyperledger fabric?
These “zero-knowledge proofs”prove that the signature on some attributes is valid and the user is in possession of the corresponding credential secret key. Such proofs, like the X. 509 certificates, can be verified with the public key of the authority that originally signed the credential and cannot be forged.
