Edu-Pro: Blockchain based Education System

Many academic institutions have begun to incorporate blockchain technology into their educational programs with the majority of them using it to assist degree management and summative evaluation for learning outcomes. This paper uses a blockchain network and smart contract to implement a new assessment system based on the ’learning is earning model.’ It is observed that students often feel the burden of studies and lack the motivation to complete assignments. In addition, the traditional method for teacher evaluation is based on students’ feedback, however it tends to be one-sided, lacking subjectivity and is hardly helpful for teachers’ improvement. Teachers also often face difficulty in correcting and interpreting theory answers of multiple students which leads to students getting biased marks. Moreover, online testing comes with its own challenges such as test result data storage, non-repudiation and result tampering prevention. To address these shortcomings, our system provides appreciation and encouragement to students as well as teachers by rewarding them with digital currency proportional to their performance. With the help of students’ unambiguous feedback, teacher evaluation will be conducted eliminating subjectivity. Further, subjective answer checking is facilitated by machine learning algorithms. This system aims to achieve increased productivity, fair evaluation, active participation and improvement in student grades.
