Novel blockchain reference model for government services: Dubai government case study

摘要

Blockchain, a Distributed Ledger Technology, is a disruptive and revolutionary technology that enables transacting data in a decentralized structure without the need for trusted central authorities. Many industries have taken steps to unleash the potential of blockchain technology, including the government sector, and early adopters are exploring the use of blockchain as one of the critical capabilities needed to create new business models and to radically transform government services and functions. However, despite this interest in adopting Blockchain technology, there is a lack of Blockchain frameworks or reference models/architecture that addresses government services in literature. In this paper, we propose a novel blockchain model that can be adopted by governments to establish government-led blockchain ecosystem for government services. The blockchain model is proposed based on the outcomes of our analysis of permissioned blockchain platform, and analysis of blockchain powered housing rentals use case that is being implemented by the Dubai Government. The proposed blockchain model outcomes includes a blockchain governance structure, participants and roles definition, and network architecture design which explains the deployment options and components. We also explain the model lifecycle and blockchain services, and we shed the light on the security and performance of the model. The study also includes exploring many blockchain use cases used by governments through proofs of concept or prototypes. Our analysis of Hyperledger Fabric design features shows the platform's relevance to government services and use cases. The Hyperledger Fabric analysis also identifies the platform's actors, services, processes and data structure of Hyperledger Fabric.
