- With the rapid digital transformation of ed- ucational and professional environments, certificate ver- ification has become a critical security concern. Tra- ditional certificate authentication systems rely on cen- tralized repositories and manual verification processes, which are vulnerable to forgery, unauthorized modifica- tion, and operational inefficiencies. Blockchain technol- ogy offers a decentralized, immutable, and transparent framework that addresses these challenges. This sur- vey presents an extensive review of blockchain-based cer- tificate authentication systems proposed in recent litera- ture. Various architectures, blockchain platforms, smart contract models, cryptographic mechanisms, and opti- mization techniques are analyzed. A detailed compari- son is presented to highlight strengths, limitations, and open research challenges. The study aims to serve as a comprehensive reference for researchers and practition- ers working on secure and scalable certificate verifica- tion solutions.
