Tamper-proof digital certificates will be needed by every education provider in the coming years and discussions about standards, metadata and validation, are slowly leading to tangible results. In May 2022, I had the pleasure to give a presentation on "Blockchain for Certificates" at the European Association of Distance Learning (EADL) in Copenhagen. Besides our Moodle plugin, I also mentioned the European Digital Credentials for Learning (EDCL) framework and the ESCO competence model. This is contrasted with the German model, which is currently being developed by xHochschule.
