Abstract


The e-Portfolio evaluation can truthfully assess the education and teaching process. This technique boasts several advantages: diverse evaluation sub-jects, emphasis on process evaluation, support to individualized develop-ment, and integration between teaching and evaluation. This paper applies blockchain to e-Portfolio evaluation, aiming to solve the thorny issues in tra-ditional e-Portfolio evaluation: privacy protection, data sharing, and infor-mation tracing. Firstly, the functional demand of blockchain-based e-Portfolio evaluation system was analyzed for multiple users: student, teacher, visitor, and administrator. Next, modular design was conducted for the sys-tem, the system boundaries and roles were defined, the relationship between roles was clarified, and a use case was provided to illustrate the client for each user. Based on the functional realization logic of the system, a se-quence diagram was plotted for the realization of system functional demand. Finally, seven chaincodes were designed to satisfy the requirements of the evaluation system. The advantages of the system performance were verified through experiments. The research results provide theoretical and practical bases for the application of blockchain in other evaluation tasks of education and teaching.
