EduChain: A Blockchain-based Education Data Management System

The predominant centralized paradigm in educational data management currently suffers from several critical issues such as vulnerability to malicious tampering, a high prevalence of diploma counterfeiting, and the onerous cost of certificate authentication. Decentralized blockchain technology, with its cutting-edge capabilities, presents a viable solution to these pervasive problems. In this paper, we illuminate the inherent limitations of existing centralized systems and introduce EduChain, a novel heterogeneous blockchain-based system for managing educational data. EduChain uniquely harnesses the strengths of both private and consortium blockchains, offering an unprecedented level of security and efficiency. In addition, we propose a robust mechanism for performing database consistency checks and error tracing. This is achieved through the implementation of a secondary consensus, employing the pt-table-checksum tool. This approach effectively addresses the prevalent issue of database mismatches. Our system demonstrates superior performance in key areas such as information verification, error traceback, and data security, thereby significantly improving the integrity and trustworthiness of educational data management. Through EduChain, we offer a powerful solution for future advancements in secure and efficient educational data management

Blockchain Securities Issues: Decentralized Identity System With Key Management Perspective

Blockchain was created many years ago to solve the problems of data transfer Integrity, several years later the issues persist. Blockchain securities are one of the most important considerations to be investigated, and data integrity is about ensuring the accuracy and validity of messages such that when they are read, they are the same as when they were first written. It is of the opinion that passing information across from one person to another cannot be the same as it was first said at the onset. Our work investigated Blockchain security issues, studying Integrity emanating from transactions across the blocks and how to deal with the securities issues. It also investigated decentralization and issues in blockchain to investigate how to mitigate the security issues associated with blockchain. It further discusses the use of key management in solving security issues in blockchain, viewing different key management systems of private and public keys, and solutions in addressing the blockchain problems. Lastly, we contributed the use of Decentralized Identity systems (DIDs) into the blockchain where we use a unique identifier, “ID.me” to verifier the individual credentials before any transaction, this was done by sending a digital ID through the issuer to the verifier to authenticate the integrity and identity of the holder and this proof worthy of protecting the information and maintaining the privacy of the user of the blockchain technology
