In cryptography a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true while the prover avoids conveying any additional information apart from the fact that the statement is indeed true.
Decentralized identifiers (DIDs) enable a verifiable, decentralized digital identity. They are designed to enable the controller of the DID to prove control over it and to be implemented independently of any centralized registry or certificate authority.
Verifiable credentials (VCs) are an open standard for digital credentials. They can represent information found in physical credentials, such as a passport or license, as well as new things that have no physical equivalent, such as ownership of a bank account.
