[[ZKP/Data Marketplace/Technical Basis/Cryptographic Foundations/Lifecycle of zk-SNARKs|zk-SNARKs]] provide security guarantees essential for the [[ZKP/Data Marketplace/Intro|marketplace's]] [[ZKP/Data Marketplace/Security and Privacy/Security and Privacy Foundations|privacy framework]], consistent with the [[ZKP/ZKP Base Layer/ZKP Blockchain/High Level Overview|base layer's]] cryptographic foundation and verified through the security infrastructure. Soundness ensures that false proofs are rejected with a probability less than 2^(-80), maintaining the same security level used throughout the ZKP Blockchain ecosystem [77]. The [[ZKP/ZKP Base Layer/Core Concepts/Zero-Knowledge Proofs|zero-knowledge property]] conceals all inputs beyond public outputs, promoting confidentiality while preserving the integrity of sensitive data.
