  11. 11. For example, after taking an examination to demonstrate his or her academic proficiency level, an individual could direct the testing organization to share the test results with one or more third-party evaluating organizations. With this diversification and the changes it brings about, different evaluating organizations may come to utilize individuals' test results in different ways, each in accordance with its own evaluation methods. http://www.sony.net/SonyInfo/News/Press/201602/16-0222E/index.html

  46. 46. Summary: Blockchain Benefits • Inbuilt identity management • Data controlled/owned by students rather than any single institution • Increases transparency • Reduces risk of fraud • Enables collaboration/interoperability • Permits disintermediation – Badge issuing based on badge collection • Lowering of process costs – Lowers entry barriers to education market – ‘university of one’
