Abstract:

This paper investigates the security issues and performance optimization of the blockchain. Security has been a hot topic in blockchain technology. Stealing cryptocurrency and disclosing the privacy of transaction process have exposed the vulnerability of blockchain in different degrees. These vulnerabilities not only caused significant losses to the project team and users, but also raised doubts about the security of the blockchain. As a formalized contract in the code, smart contracts provide a more convenient method than traditional ones, while they increase the risk of blockchain. Moreover, secure transactions should resist external attacks and protect user privacy. In addition, the performance analysis of blockchain has also aroused great interest. Therefore, this paper summarizes the related work of blockchain performance analysis from the following three aspects to promote the further research of blockchain: simulation systems of blockchain, evaluation of blockchain network and optimization of blockchain application.
