Serge Ravet offers an extended and well-argued case against the use of blockcerts in education. The term 'blockcert' refers to a specific approach using blockchain to validate digital credentials. The question being posed asks what advantage they have over badges and (especially) the Verifiable Claims W3C specification. The problem, argues Ravet, is different from the solution offered by blockchain: "A credential is not fungible, i.e. its ownership can't be transferred to someone else or transformed into something different, like exchanging a credential for a bowl of lentil stew." So there is no 'double-speding' problem, the one thing blockchain was invented to solve.
