Preface

Government


There are various applications of blockchain being researched currently that can support government functions and take the current model of e-government to the next level. First, in this section some background for e-government will be provided and then a few use cases such as e-voting, homeland security (border control), and electronic IDs (citizen ID cards) will be discussed.

E-government or electronic government is a paradigm where information and communication technology is used to deliver public services to citizens. The concept is not new and has been implemented in various countries around the world but with blockchain a new avenue of exploration has opened up. Many governments are researching the possibility of using blockchain technology for managing and delivering public services. Transparency, auditability, and integrity are attributes of blockchain that can go a long way in effectively managing various government functions.
