Blockchain for Education: Lifelong Learning Passport

2018 , Gräther, Wolfgang , Kolvenbach, Sabine , Ruland, Rudolf , Julian, Schütte , Ferreira Torres, Cristof , Wendland, Florian

Certificates play an important role in education and in professional development in companies. Individual learning records become essential for people's professional careers. It is therefore important that these records are stored in long-term available and tamper-proof ledgers. A blockchain records transactions in a verifiable and permanent way, therefore it is very suitable to store fingerprints of certificates or other educational items. Blockchain reveals forgery of certificates and it supports learning histories. In this paper, we present the Blockchain for Education platform as a practical solution for issuing, validating and sharing of certificates. At first, we describe the conceptual system overview and then we present in detail the platform implementation including management of certification authorities and certificates, smart contracts as well as services for certifiers, learners and third parties such as employers. Finally, we describe use cases and first evaluation results that we gathered from end user tests with certifiers and conclude with a discussion.

Dieses Positionspapier analysiert die Blockchain-Technologie aus wissenschaftlicher und anwendungsorientierter Sicht der Fraunhofer-Gesellschaft. Es untersucht relevante Technikaspekte und damit verbundene Forschungsfragen. Dabei zeigt sich, dass die Technik in allen Bereichen noch grundlegende Forschungs- und Entwicklungs-Herausforderungen aufweist. Diese liegen beispielsweise in der Modularisierung einzelner Blockchain-Konzepte sowie deren Kombination und Integration für anwendungsspezifische Blockchain-Lösungen.

This position paper analyzes blockchain technology from the scientific and application-oriented perspective of the Fraunhofer-Gesellschaft. It examines relevant technical aspects and related research questions. It shows that technology still has fundamental research and development challenges in all areas. These include, for example, the modularization of individual blockchain concepts as well as their combination and integration for application-specific blockchain solutions.
