The Ethereum network has long faced congestion issues, and Caldera is building a cross-regional transportation network for this digital metropolis. Unlike traditional single-chain scaling solutions, Caldera innovatively constructs interconnecting channels between aggregation layers, allowing the project to maintain the security of Ethereum while enjoying customized performance optimizations.

Caldera's core technology 'Metalayer' acts as a universal interface, skillfully integrating optimistic rollup and zero-knowledge rollup technologies. This integration allows different types of rollup solutions to connect seamlessly, much like the transfer systems of different lines in an urban subway network, significantly enhancing resource sharing and collaboration efficiency.

In this innovative ecosystem, the ERA token plays multiple roles. It is not only a pass for paying cross-summary transaction fees but also a staking certificate for participating in network security maintenance. More importantly, the ERA token grants holders voting rights on the development direction of the ecosystem, embodying the concept of decentralized governance.

In the current rapid development of Layer 2 technology, Caldera stands out among numerous Rollup solutions with its unique interoperability approach. This cross-rollup integration solution not only enhances the overall efficiency of the Ethereum network but also provides new possibilities for the future development of the blockchain ecosystem.

As blockchain technology continues to evolve, projects like Caldera that focus on ecological interoperability are likely to play an increasingly important role in the future, driving the entire Ethereum ecosystem towards greater efficiency and flexibility.
