The idea of blockchain has caught the imagination of decision-makers recently not only in finance but also in government and education. This article is a pretty good overview of how blockchain technologies might be applied in education (specifically, to support competencies and credentials, beginning maybe with badges), along with an outline of some of the costs and limitations of the technology. Some of the major differences between government and educational applications and financial applications include the use of 'permissioned' ledgers, which limits who can add data to the blockchain, and interoperability with government and educational data systems.
