Recent years have witnessed substantial advancement in the subject of smart cities. The purpose of smart city development is to enhance the quality of life for citizens. This was accomplished via the use of IoT and cloud computing technologies. Another promising technology is blockchain, which has the ability to deliver a myriad of value services to its end users. For virtual assets with value, such as Bitcoin, it is a programmable digital register that is immutable. To properly exploit blockchain technology's services inside smart cities, it is necessary to identify the technology's features, as well as its main needs and research obstacles. As such, this essay will try to define the properties of blockchain technology. Additionally, the critical needs for integrating blockchain technology into smart cities are outlined. A possible use case for blockchain technology is used to show how a smart city could be protected. There is also an overview of how a real-world three-blockchain-based smart city case study works. Finally, a number of critical research issues are highlighted and explored.
