This section outlines the cryptographic foundations of the [[ZKP/Data Marketplace/Intro|Data Marketplace]], focusing on the role of [[ZKP/ZKP Base Layer/Core Concepts/Zero-Knowledge Proofs|Zero-Knowledge Proofs (ZKPs)]], specifically [[ZKP/Data Marketplace/Technical Basis/Cryptographic Foundations/Lifecycle of zk-SNARKs|zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge)]], in supporting [[ZKP/Data Marketplace/Technical Basis/Cryptographic Foundations/Practical Applications in the Data Marketplace|privacy-preserving data interactions]]. Integrated with [[Proof of Intelligence (PoI)]] validation as defined in the base layer, zk-SNARKs enable verification of sensitive dataset attributes without disclosure, offering a framework for trust in a decentralized ecosystem.
