The SA Management Scheme Based on Blockchain for Convergence Service in S&T

A convergence service can be built by referring the specification of well-designed services and putting together them in bottom-up manner. In the service system for delivering an S&T convergence service, a service system needs to define a service agreement (SA) and to establish to support continuously and dependably the SA. In the paper we propose a SA management scheme that is used for storing the SA values co-created into the blockchain. The proposed scheme can provide a guideline for designing the S&T service system on SOA framework with a blockchain for providing information about SA as part of service metadata.
