Abstract

To keep up with demand, the rapidly expanding smart city market requires innovative technology that can make city infrastructure more efficient, transparent, and safe. In order to provide a solid foundation for the administration and optimization of smart city systems, this paper will suggest using blockchain and digital twin (DT) technologies. Virtual copies of physical objects called “digital twins” provide real-time monitoring, analysis, and management of urban assets. Distributed and immutable ledger technology, blockchain ensures data integrity, security, and transparency. Data silos, security holes, and trust issues are some of the major challenges in smart city management that the proposed framework aims to address by integrating different technologies. This statement outlines a number of difficulties. Create digital twins of buildings, transportation networks, and utility networks as a first step in the integration process. These digital twins are constantly updating their data sets with information gathered from sensors, IoT devices, and other sources ...
