// THREAT DETECTION AND DATA PRIVACY TERM
Zero Knowledge
Zero Knowledge is a security method where one party can prove to another that they know a specific piece of information, without revealing the information itself. It allows for verifying secrets, like passwords or identity details, while keeping the actual data completely private.
TECHNICAL DEFINITION
Zero Knowledge refers to a cryptographic protocol, most commonly a Zero-Knowledge Proof (ZKP), in which a prover demonstrates to a verifier that a statement is true without revealing any information beyond the statement's validity. This concept is integral to privacy-preserving technologies in blockchain (e.g., zk-SNARKs), digital identity systems, and secure authentication, enabling data validation without data disclosure.
BACKGROUND
A zero-day is a vulnerability or security hole in a computer system unknown to its developers or anyone capable of mitigating it. Until the vulnerability is remedied, threat actors can exploit it in a zero-day exploit, or zero-day attack.

USAGE NOTE
The term is most frequently applied in the context of 'Zero-Knowledge Proofs' (ZKPs) used for enhancing privacy in blockchain transactions and secure identity verification.
DEVELOPERS
