EBSILUX

EBSILUX is a collaborative project integrating Luxembourg into the European Blockchain Services Infrastructure (EBSI) that ran from February 2021 to February 2023. Led by the Luxembourg Ministry for Digitalisation in partnership with Infrachain, the Luxembourg Institute of Science and Technology (LIST), and the Interdisciplinary Centre for Security, Reliability and Trust (SnT), the project implemented verifiable credentials for academic diplomas using Self-Sovereign Identity (SSI) principles.

The technical architecture comprises software components for three key entities within the European Self-Sovereign Identity Framework (ESSIF):

• Issuer components for universities to create verifiable credentials
• Holder wallet for students to store and manage credentials
• Verifier system for employers and institutions to validate diplomas

  The implementation uses walt.id's open-source solutions for SSI functionality and relies on EBSI as a trusted registry through a dedicated blockchain node hosted in Luxembourg.

The project successfully demonstrated the feasibility of using verifiable credentials and distributed ledger technology for digital diplomas, with the University of Luxembourg as the primary implementation partner. Key technical features include:

• Compliance with EBSI and ESSIF standards
• Web-based digital wallet interface
• Automated verification mechanisms
• Integration with the EBSI blockchain network
  While the initial pilot concluded in 2023, the project identified several challenges for wider adoption, including the need for:
• Additional features like credential revocation
• Improved wallet interoperability
• Simplified verifier tools for institutions
  The system aims to enhance the efficiency and reliability of diploma issuance and verification processes while supporting student mobility across the EU.
