Blockchain technology has the potential to revolutionize digital identity management and authentication systems by introducing a decentralized, secure, and transparent approach. This paper aims to explore the key concepts, features, and potential applications of blockchain-based authentication systems. It provides an overview of blockchain technology, explaining its decentralized nature, immutability, and cryptographic foundations. The advantages of using blockchain for authentication, such as enhanced security, user control, transparency, and resilience, are highlighted. Additionally, the challenges and limitations, including scalability, interoperability, and regulatory compliance, are discussed, along with potential solutions. Successful implementations and case studies illustrate real-world applications and lessons learned. The policy implications and regulatory considerations, encompassing data protection, privacy, and governance frameworks, are examined. Finally, the importance of adopting blockchain-based authentication systems and recommendations for future research directions are outlined, emphasizing the need for continued innovation, collaboration, and the development of appropriate standards and guidelines.
