In the previous article, we learned about Caldera ERA and how it enables developers to create custom rollups linked to a unified layer called Metalayer.
But the most important question is: what makes Caldera truly different from other solutions like Arbitrum or zkSync?
The answer lies in the feature of interoperability.
What does interoperability mean in blockchain?
Interoperability simply is the ability of different systems to communicate and integrate with each other.
In the blockchain world, each network or rollup is often an 'isolated island,' making it difficult for applications within it to interact with applications existing on another network.
This isolation creates a problem known as fragmentation, where liquidity and resources are divided among multiple networks.
How does @Caldera Official address this issue?
Here is where the role of the Metalayer comes in, which acts as a unified layer above the different rollups.
Enables applications to communicate directly across different Rollups without the need for complex bridges.
Allows resource sharing (such as liquidity or data) between rollups.
Maintains the privacy and characteristics of each rollup individually.
Illustrative Example
Let's assume we have:
A DeFi project operating on Optimistic Rollup.
An NFT Marketplace project operating on ZK Rollup.
In the traditional setup, it would be difficult to connect these two projects directly.
But through Caldera and the Metalayer layer:
A user can buy an NFT from the marketplace using their assets stored in the DeFi protocol without needing a complicated transfer through bridges.
All of this happens smoothly and securely, as if they are operating within a single network.
Benefits for developers
High flexibility: the developer does not need to worry about choosing the right type of Rollup, as they can always communicate with other systems through Metalayer.
Better user experience: the end user will not have to navigate between networks or pay additional transaction fees.
Liquidity re-unification: instead of scattering assets across different networks, they can be shared and utilized throughout the entire ecosystem.
Compared to the current situation
Traditional solutions: rely on bridges that are often slow, complex, and pose a security vulnerability.
Caldera's solution: interoperability is directly integrated within the architecture via Metalayer, reducing complexity and increasing efficiency.
Conclusion
By providing effective interoperability, Caldera not only solves the scalability problem but also builds an interconnected ecosystem that makes Ethereum a more powerful and integrated platform.
It is an important step towards achieving a connected Web3, where applications can communicate seamlessly without technical barriers.
