Abstract: Blockchain technology, as one of the most popular technologies at present, has huge application value. At the same time, it is widely used in many key fields due to the high support of the country. The many characteristics of blockchain technology determine its application advantages in data sharing, digital storage, information tracing, security guarantee, etc., and at the same time, it also brings many security risks. Because of this, this article summarizes the content and related research progress of the blockchain infrastructure, security threats, and privacy protection schemes by studying on high-quality literature on blockchain security protection related research at home and abroad. Aiming to the development status of blockchain privacy protection technology, from the two aspects of encryption technology improvement and privacy protection technology fusion research,we analyze its impact on the development of blockchain, hoping to provide reference for blockchain security protection research.

Key words: blockchain, security risks, privacy protection
