Abstract

"Background/Objectives: As urbanization increases worldwide, so do the need for smart cities that enable more efficient city management. Based on smart city operational data, it explains the digital twin technologies required to predict outcomes and control according to circumstances through virtual simulations and presents related metaverse technologies. Methods/Statistical analysis: Introduction and explanation of smart city services using blockchain. The data infrastructure underlies each area, such as city operations, essential in a smart city. Findings: Therefore, blockchain is used to avoid hacking, data errors, and system failures of the existing centralized management and ensure data integrity and system stability by building a more secure server. In addition, blockchain enables the establishment of governance and free access to information through individual information sovereignty. Improvements/Applications: Most smart city models do not have a high level of authentication. Therefore, this study investigated a new smart city model that provides security and convenience to citizens by mutually complementing the virtual and real worlds by predicting urban situations through digital twins that can simulate impossible conditions in reality based on blockchain-based authentication.
