Once upon a time, building a chain was like an old scholar annotating ancient texts—meticulously proofreading word by word (adjusting virtual machines) and thoroughly verifying the entire text (calculating data costs). It took three months to make it 'stand firm,' which was already quite a feat. Now, with the arrival of Caldera's modular engine, it feels like handing a set of building blocks to a child: if you want EVM, just piece together EVM; if you want SolanaVM, just piece together SolanaVM, and you can even choose the data layer (Celestia or NEAR). In just three days, you can build a chain that looks decent.
RARI Chain and ApeChain, these 'ready-made building blocks,' are already neatly arranged, with over fifty chains taking shape. Some developers jokingly say: 'In the past, building a chain was like writing an eight-legged essay; now it's like a crossword puzzle—the ERA is that pencil for filling in the crossword, not expensive, but indispensable.'
