In multi-chain networks, Data Availability (DA) is the underlying cornerstone that determines security boundaries. The lack of efficient DA not only poses barriers to user asset verification but also opens the door to potential attacks. Caldera's Metalayer redefines this issue from a global perspective.

Caldera believes that DA is not merely a storage challenge, but a dynamic collaboration of storage, transmission, and verification. Metalayer introduces a layered data strategy:

Core Layer: Critical state data is hosted by a core validator cluster, ensuring it is always verifiable and responsive;

Optimization Layer: Low-sensitivity data reduces on-chain burden through compression and batching, enhancing performance;

Open Layer: Supports access to external DA services, allowing developers with different needs to freely choose compatible solutions.

This flexible architecture balances security and scalability, capable of meeting the high-security standards of financial applications while also accommodating high concurrency in gaming, social, and other services. For nodes, staking $ERA and participating in DA services can also yield economic incentives, further enhancing network redundancy and reliability.

The #caldera of @Caldera Official binds the economic model to data integrity, transforming DA from a behind-the-scenes cost into ecological value. $ERA is both the network fuel and a proof of trust. As on-chain demand grows, Caldera's data layer may become the reference paradigm for the next generation of Rollups.
