Abstract: As a new direction for the development of digital industry and an emerging technology for economic and social development, blockchain is a strategic industry for the construction of an information-based country, and will have an increasingly far-reaching impact on the future production and life style. With the wide application of blockchain technology and people’s continuous attention to digital privacy, blockchain privacy protection has become a key factor restricting the promotion of blockchain. Now it is urgent to analyze and sort out the research progress of blockchain privacy protection technology, so as to provide a basis for further research and breakthroughs on key issues of blockchain privacy protection in the future. By analyzing the privacy characteristics of blockchain, this paper summarizes the risks of blockchain in privacy protection from the data layer, network layer, transaction layer and application layer, and lists the relevant technologies, principles and application scenarios of privacy protection at various levels in detail. Finally, the challenges and development direction of blockchain privacy protection technology under the development of emerging technologies are prospected.

Key words: blockchain, privacy protection, information hiding, coin shuffle
