Privacy-preserving cryptography is a collection of cryptographic techniques designed to enable computations or transactions on data without revealing the underlying information itself. This includes methods like zero-knowledge proofs, homomorphic encryption, and secure multi-party computation. These techniques allow for verification and interaction within digital systems while maintaining the confidentiality of sensitive user data. They are crucial for building privacy-centric blockchain applications.
Context
