摘要：

In the traditional Service Oriented Architecture(SOA), evaluations of services are results from accumulated remarks, which means that they lack real-time feedbacks. In this paper, we propose an advanced architecture combined by SOA and block-chain. We take the advantage of the stable time-slot generated by the consensus algorithm to clock the service pool, making it possible to evaluate the real-time states of services. Moreover, we propose a mathematical model based on the Markov Chain to assess and predict the compatibility of a service in a time-slot. And we assess and evaluate the distribution of compatibility by bringing in four well-known consensus algorithms (Bitcoin's PoW, PPCoin's DPoS, Fabric PBFT, PBFT+DPoS) which generate different lengths of time-slots. The result shows that our compatibility assessment model works well and that the distribution varies with different consensus algorithms with the rankings of effects as follows: PoW, PBFT, DPoS, and PBFT+DPoS. © 2020, The Editorial Board of Journal of Xidian University.
