Blockchain is one of the most disruptive and emerging technology in the present era, due to its unique characteristics immutability and decentralization. The transactions in a blockchain are publicly available, thereby accessible to all users. So, the privacy provisioning in blockchain for transactions of decentralized social media as well as privacy of the identities of members is needful. The chapter provides a comprehensive study of privacy provisioning on the blockchain. In the existing literature, there are a variety of scalability, security, and privacy concerns with blockchain, including key management for recovery, on-chain privacy protection, transaction linkability, and adherence to privacy laws. Following the self-sovereign identity (SSI) model, new privacy-preserving blockchain solutions are emerging to address these issues. These solutions allow users to anonymize themselves in all types of electronics transfer ledgers and regain control of their personal information. This chapter provides a comprehensive study of privacy provisioning schemes along with their challenges in this fascinating and disruptive technology.
