Exploration of the system of evaluation system of university teachers’ titles based on blockchain technology

Abstract

Abstract The purpose of this thesis is to combine blockchain technology with teacher title evaluation, and design a blockchain-based teacher title evaluation system using the characteristics of blockchain and IPFS, and other technologies. The system adopts a three-layer architecture consisting of a data storage layer, an application business layer, and a user presentation layer. Among them, the data storage layer builds a distributed network through Ethernet blockchain nodes. At the same time, each node is also an IPFS network node, responsible for uploading teacher certification materials to the IPFS network through the file encryption module in the application business layer and generating IPFS abstracts, which can be subsequently uploaded to the chain only, i.e., ensuring the privacy of file materials and reducing the overhead of storing data. To verify the effect of the title review system, the analysis was conducted in terms of role perceptions, covering teachers’ perceptions of the fairness and motivation of the title review system. In terms of fairness of the review criteria, 60.83% of teachers think it is fair, and 25.83% think it is unfair. 65.83% of teachers say that the career review is helpful for career development, and only less than 10% think it is not helpful for career development. It shows that this teacher title evaluation platform is efficient, intelligent, secure, and trustworthy.
