Blockchain for government services — Use cases, security benefits and challenges

摘要

Public sector and governments have been actively exploring new technologies to enable the smart services transformation and to achieve strategic objectives such as citizens satisfaction and happiness, services efficiency and cost optimization. The Blockchain technology is a good example of an emerging technology that is attracting government attention. Many government entities such as United Kingdom, Estonia, Honduras, Denmark, Australia, Singapore and others have taken steps to unleash the potential of Blockchain technology. Dubai Government is aiming to become paperless by adopting the Blockchain technology for all transactions by 2021. The Blockchain is a disruptive technology that is playing a vital role in many sectors. It's a revolutionary technology transforming the way we think about trust as it enables transacting data in a decentralized structure without the need to have trusted central authorities. Blockchain technology promises to overcome security challenges in IoT enabled services such as enabling secure data sharing and data integrity. However, it also introduces new security challenges that should be investigated and tackled. In this paper, we review the literature to identify the potential use cases and application of Blockchain to enable government services. We also synthesized literature related to the security of Blockchain implementations to identify the security benefits, challenges and the proposed solutions. The analysis shows that is huge potential for Blockchain technology to be used in to enable smart government services. This paper also highlights future research in the areas of concerns that required further investigation.
