PRIVACY-PRESERVING TECHNIQUES IN BLOCK CHAIN NETWORKS

Abstract

Block chain technology, while revolutionizing various sectors, faces significant challenges regarding data privacy and security. As block chain networks become more widespread, the need for privacy-preserving techniques becomes critical to ensure the confidentiality, integrity, and anonymity of user data. This article reviews various privacy-enhancing techniques implemented in block chain networks, including cryptographic protocols, zero-knowledge proofs, and off-chain solutions. The aim is to identify their effectiveness, limitations, and the trade-offs between privacy and performance. Through a comprehensive analysis, this study explores existing methodologies and suggests potential improvements for safeguarding privacy while maintaining the decentralized and transparent nature of block chain systems.
