Urbanization exacerbates challenges in housing, transportation, energy, environment, welfare, and safety. This study proposes a "DID-based safe smart city model using digital twin" to enhance citizens' quality of life and advance societal development. We develop a standardized layer model for the Cognitive Internet of Things (CIoT) environment, utilizing blockchain's distributed ledger technology and Decentralized-Identity (DID) for secure device communication. Emphasizing explainable AI (eXplainable Artificial Intelligence), the model ensures transparency in processing IoT-collected big data. By integrating autonomous decision-making algorithms and real-time 3D data visualization through digital twins, the model enhances problem-solving and preventive capabilities. This research distinguishes itself by combining CIoT, blockchain (DID), and digital twin technologies to create a comprehensive smart city standard model addressing content integration and scalability.
