Background: In traditional e-commerce systems, data is usually stored in a centralized mode, and a trusted third party must be found. However, once there is a problem with the third-party database, it will lead to issues such as data privacy and security. The use of blockchain technology can reduce data privacy and security issues caused by human factors, reduce data disputes and improve the development speed of the e-commerce industry.

In this paper we will propose distributed ledger, provides important guidance for enterprises to operate and manage blockchain-supported e-commerce application.
