What makes cross-chain messaging secure? The answer lies in DVN architecture.

Think of DVNs as independent checkpoint systems. Every time a message leaves the source chain, these verification networks kick in to authenticate it before it reaches its destination. No single point of failure, no blind trust.

What's clever here is the modular design—projects can choose their own DVN setups based on security needs. Some might want multiple layers of verification, others prefer speed with baseline safety.

This verification layer is what separates robust cross-chain infrastructure from the risky bridges we've seen collapse before. LayerZero basically turned message verification into a customizable security framework rather than a one-size-fits-all solution.
