It is reported that Caldera is an Ethereum-based Rollup platform designed to achieve horizontal expansion and interoperability between Rollups. Caldera does not focus on optimizing a single blockchain, but allows project parties to launch customizable Rollups while maintaining the security and decentralization of Ethereum. The platform introduces Metalayer, a unified layer designed to connect Rollups based on optimistic and zero-knowledge (ZK) frameworks, thereby achieving coordination, communication, and resource sharing while retaining the unique characteristics of each Rollup.
