A Permissioned Blockchain-Based Platform for Education Certificate Verification

Distance education has become an important learning method for students. Nevertheless, online teaching is difficult to ensure the traceability of student activities. The difficulty in managing the non-instantaneous diploma verification and digital/paper files have always been severe problems in education management. The education information stored within the current centralized system is simply leaked and cannot be guaranteed in terms of impartiality and authenticity. In the present paper, a digital education certificate prototype is designed utilizing the permissioned blockchain of PKI-CA, digest algorithm, and interactive data authentication by digital signatures. The digital certificates can be issued by the system realizing the instant certificate verification between students and third parties via QR codes or dynamic authorization codes. The test results indicated that 100% correct work of the prototype, with the significant throughputs of getting and creating transactions are respectively 1982.6 tps and 263.9 tps on-chain during the test cycle.
