Issues and challenges associated with blockchain in smart cities

ABSTRACT
Since its inception, the blockchain technology has shown promising application prospects. From the initial cryptocurrency to the current smart contract, blockchain has been applied to many fields. Conventional IoT ecosystems involve data streaming from sensors and different devices to a centralized cloud computing server. Issues that arise include security and privacy concerns due to third party management of cloud computing servers, single points of failure, a bottleneck in data flows and difficulties in regularly updating firmware for millions of smart devices from a point of security and maintenance perspective. One can enable smart cities with a blockchain to offer enhanced security via storing transactions in a secure, transparent, decentralized, and immutable ledger. However, both blockchain and smart cities are in their infancy and significant research efforts are needed to integrate them. In this paper, we comprehensively review the role of blockchain in enabling IoTbased smart cities.
