What is blockchain and how does it apply to higher education? In this episode of Thinking Outside the Sandbox, Sandbox Deputy Director of Research Brian Fleming sits down with Chris Jagers, CEO of Learning Machine, a company that creates software for education providers, employers, and students to create and issue and track digital certificates using block chain technology, to explore the use of blockchain technology in higher ed, and its impact on a host of issues from digital transcripts and alternative credentials, to privacy, security, and authenticity. Sandbox is pleased to present this podcast as part of our ongoing coverage of pedagogical innovation and higher education, and of the many promising practices taking shape across the industry through the use of technology.
