However, there are some privacy challenges that may hinder the applications of blockchain. The goal of this survey is to provide some insights into the privacy issues associated with blockchain. We analyze the privacy threats in blockchain and discuss existing cryptographic defense mechanisms, i.e., anonymity and transaction privacy preservation To protect your privacy, you should use a new Bitcoin address each time you receive a new payment. Additionally, you can use multiple wallets for different purposes. Doing so allows you to isolate each of your transactions in such a way that it is not possible to associate them all together Although there are some studies on the security and privacy issues of blockchain, there lacks a systematic examination on the security of blockchain systems. In this paper, we conduct a systematic study on the security threats to blockchain and survey the corresponding real attacks by examining popular blockchain systems
