Caldera (ERA) is a rollup platform on Ethereum that allows for horizontal scalability and interoperability between rollups. Instead of optimizing a single blockchain, Caldera enables projects to launch customizable rollups with the security and decentralization of Ethereum. The platform features Metalayer, a unifying layer designed to connect rollups across different optimistic and Zero Knowledge (ZK) infrastructures. This allows for coordination, communication, and resource sharing while preserving the distinctive characteristics of each rollup. Caldera's native governance and utility token, $ERA, is used for the following: - Paying transaction fees within Metalayer for interactions between rollups. - Staking for validator nodes participating in the network. - Participating in governance decisions regarding protocol updates and treasury allocations.
