The concept of a Smart City originated in the media industry, referring to the use of various information technologies or innovative concepts to connect and integrate city systems and services. The goal is to enhance resource efficiency, optimize city management and services, and improve the quality of life for citizens. SC is an investment of Rhine Capital in Germany and developed by the Hanover Tenacity Laboratory through three years of exploration into the combination of blockchain and smart cities. It is a perfect ecosystem, born from this exploration. SC will leverage user participation in the real-world applications of smart cities across various levels, rewarding users with tokens which are then returned to B-end parties. This fosters tighter C2B integration, identifies shortcomings in smart city applications, and prompts B-end parties to make improvements. Ultimately, the goal is to achieve perfect harmony between people and the city.
