Currently, ideological and political education faces three major pain points: mismatch of information supply and demand, obstacles to resource sharing, and lack of trust between the subject and object of education. Based on this, this study applies blockchain technology to the informatization management of college students’ ideological and political education in colleges and universities and designs the functional framework and main functional modules of the informatization management platform of college and university ideological and political education. Teachers and students of a regional university are selected as the research samples, and after analyzing the application of the platform by teachers and students of the university, we construct the evaluation indexes of the platform’s system structure and system function and use the DBN model to evaluate the application effect of the platform. The results show that after the use of the Civic and Political Education Informatization Management Platform, the sample teachers and students have a better knowledge and use of it, and 65.8% of the teachers and students have a higher frequency of use. The ideological and political education informatization management platform obtains a better application effect, with evaluation scores of 75.3 and 85.7 for its system structure and system functions, and it obtains excellent performance in the quality and organization of teaching resources, the construction and sharing of high-quality teaching resources, and the improvement of management efficiency. The organic combination of blockchain technology and ideological and political education in colleges and universities can improve the level of ideological and political education and promote innovation and optimization of the education model.
