Authors - Oleksii Shapoval Abstract - Stackable micro-credentials have a significant potential for making the study process more flexible and personalized. The paper introduces an approach for managing educational processes related to the acquisition of stackable micro-credentials with the use of blockchain technology. The approach allows learners to build verifiable personalized skill trees with cryptographic provenance of their progression. The paper first outlines related works in the fields of micro-credentials, stackable credentials, and the application of blockchain technology in education and knowledge certification. Then, the approach is described, starting with a high-level overview, elaboration on incorporated technologies, and a description of the main processes. The contextualization of the work is then provided, elaborating on implications and practical advantages of the presented approach. The research contributes to the field of knowledge management by providing a practical blueprint for how blockchain technology can be applied for personalization of learning process. This approach can be applied for a number of use-cases, from small-scale workshops to online courses and education institution environments.
