Caldera is the 'master scheduler' for multiple Rollups, and ERA is the fuel that keeps this scheduler running.
For developers, Caldera's greatest value lies in its ability to pull isolated Rollups into a unified Metalayer, allowing direct verification of states between chains without relying on third-party cross-chain bridges through lightweight clients and aggregated signatures. This not only reduces security risks but also saves a significant amount of Gas.
ERA's role here is to drive the entire network—sending cross-Rollup messages and executing verification tasks require ERA, and nodes need to stake it to participate in consensus. Even better, ERA can also participate in governance, such as proposing new functional modules and adjusting fee mechanisms, which is crucial for ecological development.
As more projects connect to Caldera, scenarios requiring multi-chain collaboration, such as cross-chain DEXs, on-chain games, and AI applications, will increasingly emerge, and the frequency of ERA's usage will rise accordingly. In simple terms, it is the essential lubricant for the 'multi-chain interoperability' machine.
