Donald Clark was a fan of blockchain a couple of years ago but he reports that he has "fallen out of love with this technology" because "I’ve still to see a single implementation in learning that is worth the candle." I think this is true, and I think most of the educational implementations to date have been trivial. But I'm more concerned about this: "In truth education and training does not want to be decentralised and democratised or disintermediated, as almost everyone in the field works in an institutions that will protect themselves to the death." This is also true, and what we might see in education is the educational version of Stellar or Ripple: the big banks creating their own version of the tech and setting up their own centralized network. But I also think there more to the picture than badges and credentials. More to come. Soon.
