This paper analyses the technical characteristics and working principle of Block Chain, combines with distributed network nodes and refers to Information Capability Evaluation System, studies the implementation principle and complexity of these methods, summarizes their suitable environment and advantages and disadvantages, and proposes a Evaluation Trust Model of Block Chain Information Capacity Based on Subjective Logic (ETMBCIC-SL). This model introduces Jøsang's Subjective Logic to detect the block chain accounting behavior, so as to solve the dynamic trustworthiness problem of the Block Chain's privilege control, and dynamically detect the Block Chain privilege control through independent viewpoint and dependent viewpoint. The simulation results show that the model has high Completeness, Accuracy and Instantaneity.
