Summary:The use of blockchain in various fields is increasing rapidly because of its transparency and decentralisation. However, the transparency and immutability of data on the blockchain have prompted questions about data privacy. The intention of this study is to investigate the many theories and solutions made to deal with data privacy in blockchain applications. This paper covers an overview of privacy-preserving techniques like secure multi-party computation, ring signatures, homomorphic encryption, and zero-knowledge proofs, as well as the concept of local differential privacy in data privacy on blockchain. This paper also covers the data privacy challenges in blockchain applications. Overall, the aim of this article is to furnish the latest research and future trends regarding data privacy in blockchain applications and its importance.
