Recently looked at @Caldera Official , and it feels like it has made the act of 'building a chain' no longer feel so aloof.
In the past, creating a chain had a technical threshold as high as climbing to the sky, and it required a lot of money; whereas #Caldera 's approach is: with just a few clicks, you can quickly build your own Rollup, as easy as opening a small online store.
It also supports various modular combinations—whatever settlement layer, DA layer, or proof system you want, you can choose them all yourself. For project teams, this means 'freely building your own chain', no longer passively squeezed onto a major public chain paying high fees.
$ERA can also be considered the underlying 'fuel ticket' in the ecosystem; if Rollup continues to explode in the future, tool-like projects like Caldera will definitely have a chance.
