Abstract: 【Purpose/significance】In order to improve the e-commerce credit system, optimize the e-commerce environment, and im?
prove the security of e-commerce activities, an online e-commerce credit information sharing method based on blockchain technology
is proposed.【Method/process】This paper first constructs the framework of online e-commerce credit information sharing platform. By integrating digital blockchain technology and transaction blockchain technology into online e-commerce credit information sharing
platform, digital blockchain technology completes the data information preprocessing process, and uses Byzantine fault-tolerant
mechanism to build a consensus model to ensure the stability of online e-commerce credit information sharing platform; The blind sig?
nature algorithm in the transaction blockchain technology improves the security and sharing efficiency of credit information, and real?
izes the sharing of e-commerce credit information.Finally, through comparative experiments, the proposed e-commerce credit informa?
tion sharing method is tested.【Result/conclusion】The experimental results show that the proposed method has low communication
overhead, high throughput, low latency, high securityand strong practicability.【Innovation/limitation】Since this paper does not verify
the proposed method in combination with actual cases, the research conclusions have certain limitations, and further research and dis? cussion are needed in the future.
