Stackability planning in informal learning and soft skill acknowledgments

This paper assesses the issue of stackable learning paths in the context of expanding the capabilities of the DCP host that manages digital badges based on the Open Badge 2.0 standard. Blockchain technology helps to keep diverse, interrelated data elements in a coherent unit. The up-to-date state of the stackable certificate system supported by soft skills is ensured by IPFS-based data storage. A model for this is presented in the paper.
