Diploma Issuing On The European Blockchain Service Infrastructure

Traditional systems of academic credential verification are often cumbersome, prone to fraud and inefficient. Often, they require the involvement of several organizations to verify the validity of one credential, leading to difficulties for individuals to prove that their certifications are trustworthy and Higher Education Institutions (HEIs) and employers having a hard time verifying them. The proliferation of fake credentials undermines not only HEIs but also several other sectors of society, such as healthcare, posing a great risk to public safety. This work aims to tackle this issue by describing a blockchain-based system employing the European Blockchain Service Infrastructure (EBSI) for the issuance and verification of academic certifications. By leveraging the blockchain’s intrinsic qualities of security, immutability and decentralization, the solution provides a more secure, transparent and efficient processes of credential issuance and verification. After conducting a thorough systematic literature review of related implementations, several key architectural approaches were considered, namely the use of standardized data models for credential creation, the use of automation for data handling, and the adoption of digital wallets for credential storage. Furthermore, the developed system establishes a hierarchical trust chain, integrates trusted authentication mechanisms, ensures regulatory compliance and provides a simple mechanism for credential issuance and verification. Several security and scalability tests were conducted, guaranteeing the easibility of the system.
