The research landscape in the emerging field of digital government and industrial metaverse applications is rapidly evolving, with a strong emphasis on integrating advanced technologies to enhance public services and industrial training. Recent developments highlight a shift towards leveraging blockchain services, particularly Non-Fungible Tokens (NFTs), to create more sustainable and interoperable smart city ecosystems. These innovations aim to bridge the gap between physical and digital realms, fostering a more integrated metaverse experience. Additionally, there is a notable surge in the use of Virtual Reality (VR) and game engines, such as Unreal Engine, to develop immersive training applications for industries like shipbuilding, addressing critical safety and operational challenges. These advancements not only promise to revolutionize traditional training methods but also to set new standards for user engagement and decision-making in high-stakes environments. The integration of these technologies underscores a broader trend towards creating more interactive, efficient, and secure digital environments, with significant implications for both public administration and industrial practices.
