This is an overview article of the potential of the blockchain in higher education. We've covered the blockchain in OLDaily before. In a nutshell: a transaction (contract, credential, whatever) is encrypted in a block, and the block is added to a chain of encryptions. So the transaction is public and verifiable, but secret and secure. It's tempting to imagine a network of competencies, badges and blockchains, as Doug Belshaw did last year, but the Tapscitt version is a lot more conservative: "a student receives a custom learning experience from a dozen institutions, while the blockchain serves to track the student's path and progress."
