This is a puff piece promoting Greenlight Credentials but it does offer one of the more compelling use cases for blockchain in education: "The benefit of a distributed ledger technology like Blockchain is that it allows employers and colleges to have instant verification of a multiple-source transcript." The key here is multiple-source. "Student profiles can host a range of evidences of learning including badges and a portfolio of artifacts." Of course, when you have multiple credentials in a single space, no one credential is special any more. Cue the crisis in academia.
