Definition

a verifiable, boolean assertion about the value of another attribute in a verifiable credential

Note

Derived predicates are useful in zero-knowledge-proof-style verifiable presentations because they can limit information disclosure. For example, if a verifiable credential contains an attribute for expressing a specific height in centimeters, a derived predicate might reference the height attribute in the verifiable credential demonstrating that the issuer attests to a height value meeting the minimum height requirement, without actually disclosing the specific height value. For example, the subject is taller than 150 centimeters.
