Rollups are a type of Ethereum scaling technology that can package a large number of transactions and submit them to the mainnet, preserving Ethereum's security while significantly reducing transaction fees and increasing speed. Common types include Optimistic Rollups and ZK Rollups.
Caldera (ERA) is a Rollup ecosystem that emphasizes "modularity, interoperability, and customization", with the goal of creating a network of interconnected chains. Developers can easily deploy their own Rollups through Caldera, optimizing performance and cost for different applications such as gaming and DeFi. ERA, as the representative project of Caldera, is driving the next generation of scalable blockchain architecture, allowing each application to have "its own chain". This not only enhances user experience but also opens a new chapter for Web3.
