Definition ∞ Zero knowledge sets are cryptographic constructions that allow a prover to demonstrate membership or non-membership of an element within a set, without revealing any information about the set’s contents or the specific element. This technique offers privacy-preserving capabilities. It is a variant of zero-knowledge proofs, providing selective disclosure.
Context ∞ Zero knowledge sets are increasingly relevant in privacy-focused blockchain applications and decentralized identity solutions. They enable users to prove qualifications or ownership without disclosing sensitive personal data or the full list of members. This technology is critical for enhancing user privacy and compliance in digital asset transactions and identity verification systems.
