SD-SmartCert: A Blockchain-Based Certification System with Selective Disclosure

Abstract

The research paper explores the concept of selective disclosure within blockchain networks, addressing the tension between transparency and privacy. It introduces cryptographic schemes that allow users to reveal only necessary information, maintaining confidentiality. The paper analyzes various selective disclosure methods, such as Zero-Knowledge Proofs and Attribute-Based Encryption, highlighting their applications in enhancing privacy and security in digital transactions. It also discusses the implementation of these schemes in blockchain for certification system, emphasizing their potential to foster trust and promote wider adoption of blockchain technology across different industries. The paper concludes by identifying future research directions to optimize these cryptographic protocols for better scalability and interoperability in blockchain systems.
