The architecture design of training data microservice based on blockchain technology

In order to build a data-driven service system and improve the scientific level of the training department's work efficiency, we adopt the concept of microservice development. Utilizing the distributed, fault-tolerant, and sharing characteristics, we apply blockchain technology to the back-end data system and deploy a lightweight front-end sharing architecture, realizing the design concept of training data microservice model. In this paper, we start with the actual needs of combining the characteristics of blockchain technology and training data, focusing on analyzing the application logic and applicable scenarios of blockchain technology in training data microservice. We propose the concept of credible data sharing service for on-chain storage and off-chain transmission, and designed a blockchain-based database access control mechanism. Finally, we propose the experiment and the conclusion to the application system development method of the service.
