SoulCert - Decentralized and Secured Certification System Using Soul-Bound Non-fungible Token

The paper introduces SoulCert, a decentralized application that leverages blockchain technology to address the challenges of academic certification. Utilizing soul-bound non-fungible tokens (NFTs), SoulCert provides a secure and transparent system for issuing, verifying, and managing tamper-proof academic credentials. The system extends the ERC721 standard with additional functionalities from ERC5192 for locking and unlocking tokens, ensuring the integrity and authenticity of certificates. The paper discusses various Ethereum token standards, their use cases, and the methodology behind SoulCert, highlighting its potential to revolutionize the academic certification process. The paper also presents performance comparison between different operation within SoulCert and economic feasibility for real world application.
