In this article [“Blockchains for Government: Use Cases and Challenges“, author Yelena Yesha et al. review] blockchain concepts and use cases, and discuss the challenges in using them from a governmental viewpoint. [They] begin with reviewing the categories of blockchains, the underlying mechanisms, and why blockchains can achieve their security goals.
[They] then review existing known governmental use cases by regions.
