#caldera and $ERA @Caldera Official Blockchain which helps other projects in building their own blockchains which is known as "rollups". Caldera also make many rollups work side by side which as a result makes the whole system faster and more flexible. "ERA" is the token used in the Caldera system. Let me explain you with an example for your better understanding.

EXAMPLE:

Ethereum is like a tall building with only one slow elevator (Layer 1). Everyone has to wait in line. Caldera creates many small, fast elevators (rollups) on each floor. You get to where you need to go faster but you’re still inside the same building (Ethereum).
