The invention discloses a student behavior information verification system based on a blockchain technology. The characteristics of distributed structure, automatic trust establishment, tamper-proofing, anti-counterfeiting, traceability and the like are used to solve the problems of high information verification cost, low efficiency, insecure security and the like, which are caused by damage or loss of student behavior information supporting materials. The system consists of a blockchain technology module, a registration / login module, an information release module, an information audit module,an information sending module and a query verification module. A relatively complete student behavior information chain is formed, and a unified interface service is provided for external parties. Onthe basis of ensuring the validity and reliability of student behavior information verification, the system greatly improves the work efficiency of tedious self-certification and verification of students, school management departments, enterprises, institutions and the like, and reduces the human resource cost of student behavior information maintenance.
