Abstract	Because urban populations will be the growing faster in years to come, many initiatives including smart city projects have been proposed to meet the needs of urban people and to improve their quality of life. Sustainability, energy efficiency, and a green environment are the major aspirations of smart cities. Many challenges, including air quality, energy efficiency, urban mobility, safety and security, have been faced to make the smart cities concept a reality. However, perhaps in all such things the major challenge faced by the smart cities is data privacy and security. In this paper we have discussed securing smart cities using block chain technology. A smart city uses many sensors and actuators, and it is relying completely on the concept of the Internet of Things (IoT). To maintain sustainability and real-time deployment of smart cities the necessary factors required are secured wireless connectivity and IoT. Being smarter also makes the city more vulnerable to cyber attacks. We have proposed a comprehensive survey about various applications such as healthcare systems, smart vehicles, smart trafficking, and smart economy sharing services in the smart cities, which implements blockchain technology. Case studies of smart Dubai and smart London have also been presented in this paper. © 2021 Elsevier Inc. All rights reserved.
