## Cross-Chain Data Validation

Cross-Chain Data Validation is the process of verifying data integrity as it moves across different blockchain networks. This is crucial for cross-chain bridges and protocols that operate on multiple chains simultaneously.

By using cryptographic proofs or relayers, systems ensure that data originating on one chain is valid and untampered when received on another. This prevents attacks where fraudulent messages are injected into the cross-chain communication layer.

It is a critical infrastructure component for the interconnected multi-chain financial ecosystem.
