Some may ask, is Caldera's Rollup a departure from Ethereum? On the contrary. Caldera is essentially Rollup-as-a-Service, specifically designed to scale Ethereum. It does not seek to challenge Ethereum's status, but rather to help more applications better rely on Ethereum.
In other words, Ethereum is the security foundation, and Caldera is the performance accelerator. It's like having many cars on a highway; Ethereum is the main road that everyone uses, but it can get congested. Caldera provides a dedicated express lane for certain large vehicles, which does not compromise the safety of the main road and allows the vehicles to go faster.
For the entire Ethereum ecosystem, this is a win-win situation. Applications gain performance, and Ethereum gains more usage scenarios and value accumulation. Therefore, Caldera is not meant to replace anyone but to make the entire ecosystem smoother. This is why more and more projects are beginning to consider using Caldera to create their own Rollup.
