A Feedback Management System Based on Blockchain Technology for Educational Institutions

The provision of feedback is an essential element in the process of enhancing the performance of an organization. With precise feedback, errors and possibilities for improvement can be determined. The purpose of every survey is to accurately capture individuals’ real feelings. Today, the majority of feedback data is stored in a database system, However, a lack of confidence in the database system results in inaccurate or partially compromised feedback. Blockchain is an innovative and promising technology that decreases security risks, eliminates fraud, and provides unprecedented levels of transparency to ensure feedback system efficiency. It is a decentralized ledger that has earned widespread attention in numerous industries. This paper investigates the use of a digital feedback management system based on blockchain technology in educational institutions that could be used to keep individual survey results safe and accurate. The proposed framework involves developing a suitable design for a feedback management system and verification of every feedback result. The system was implemented using the Java programming language. The performance of the proposed system was tested by using the number of transactions processed per second(throughput). Experimental results showed the system can verify 200 transactions in 3 seconds. In addition, the test demonstrated that the system retrieves 100–400 transactions in less than a second and 500–1000 transactions in less than 2 seconds. The throughput results were compared to the same metrics taken for several common applications. The suggested system achieved a high level of throughput when compared to several popular blockchain-based applications.
