Study on Blockchain-Based Certificate Verification and Validation

This review critically examines the developing state of blockchain technology as an evolutionary measure to improve the security, transparency and efficiency of certificate authentication and verification processes. Conventional approaches are usually susceptible to forgery, time-consuming manual actions and lacking inherent trust. The core features of immutability, decentralization, cryptographic hashing and verifiable chain of transaction provided by Blockchain create a profitable paradigm shift to create tamper-proof and easily verifiable digital certificates. This paper gives an up-to-date and comprehensive review of the literature, sets the background context necessary for understanding the challenges of legacy systems, critically surveys the various methodologies being sought and employed, emphasizes new and emergent applications in an extensive range of industries and concludes by briefly discussing open issues and promising areas for future research and development in this emerging field.
