Design And Implementation Of Mashup Service Syetem Based On Blockchain

Service-Oriented Architecture(SOA)has become an attractive computing paradigm by leveraging advances in Web technologies and software engineering.Web services are the key support technologies of SOA.In recent years,they have experienced rapid development and played an increasingly important role in ecommerce and enterprise application integration.The use of Web services is becoming more frequent today,and the demand for Web Mashup services is increasing.Web Mashup is a web application developed using content and services provided online,that is,when a single service fails to meet demand,we can combine loosely coupled and highly reusable services to provide complex functionality.Based on the realization of a single service API,this thesis can combine multiple services.At the same time,it improves the service aggregation module in the traditional Mashup service system,the output module is not clear,the output result is not in line with expectations,and the combination mode is single.Based on this,a service composition method based on BPMN diagram was developed,which greatly increased the accuracy,readability and clarity of the Mashup service composition.At the same time,the conditional constraints in the BPMN diagram increase the flexibility of the Mashup service portfolio.Moreover,this thesis combines the Mashup service system with the blockchain technology,and uses the new application mode of computer technology such as distributed data storage,point-to-point transmission,consensus mechanism,and encryption algorithm of blockchain technology to package the data generated by the service system storage.
