Microservices have been fused into the design framework of Internet applications over time. It is necessary to evaluate the application value of microservices fairly and transparently on a regular basis to improve the value of microservices, promoting developers to upgrade low-cost microservices. Therefore, a microservice evaluation system based on blockchain technology is proposed. It records the evaluation data of each dimension of microservices with the distributed accounting and consensus algorithm of Hyperledger Fabric blockchain technology, protecting the non-tampering and traceability of evaluation data. Besides, this study combines the analytic hierarchy process and the entropy method to build a comprehensive evaluation model of microservices and then calculates the comprehensive score of them. Experimental results demonstrate that the system can trace the source of the evaluation results of microservices, producing more reasonable results than a single evaluation model. It can provide effective data support for intelligent management of microservices.
