Imagine a future society based on Blockchain: each project is like a city, and each chain is its infrastructure. In this society, Rollup technology can be used to build various functional areas, such as residential areas, financial centers, and transportation networks.

In this vision, Caldera plays the role of a city developer, providing a full suite of solutions. However, the true core driving this city is ERA. ERA is not just a token; it is more like the lifeline of this on-chain city—serving as the power supply, municipal fees, and the cornerstone of community governance.

Although ERA may not be the most eye-catching element, it plays a crucial role in the operation of the city. It determines the normal functioning of infrastructure and affects all aspects from water and electricity supply to the tax system. ERA represents the perfect combination of administrative costs and operational credit, and is key to the normal operation of the city.

If Caldera is the tool for designing and building this digital city, then ERA is the fuel that ensures the stable operation of this city. It is not just a simple token, but a core component of the entire on-chain city ecosystem.

This new model of urban governance demonstrates the potential applications of Blockchain technology in future social management, painting a picture of a future filled with innovation and efficiency.
