As the Class Central report suggests, this article reminds us of Audrey Watters's outline of blockchain in education dating from April of 2016 (where she wrote "One Bitcoin is currently worth about $415" - heh). "Decentralised trust systems may well be the future but I don't see that it solves a core problem," writes Chris Fellingham. "Edtech... does not have a problem of trust in its credentials — it has a problem of credibility in its courses." It may be that the decentralization blockchain enables might be valuable, he writes, but it may come with a cost, just as decentralization of news media brought with it the scourge of fake news.
