Cross-chain Messaging Standardized

Cross-chain messaging was the wild west for years. Every bridge with its own protocol, security model, integration requirements. Building multichain apps meant learning five different systems.

The space is consolidating around a few major players now. LayerZero, Chainlink CCIP, Wormhole dominate. Each with different tradeoffs but increasingly similar interfaces.

What changed is developers stopped caring about the underlying mechanism. They want to send messages between chains. How that happens underneath matters less than reliability and cost.

The security models still differ significantly though. CCIP leans on Chainlink's oracle network. LayerZero uses configurable security. Wormhole has its guardian set. Understanding these differences matters for high-value applications.

CCIP makes sense for projects already using Chainlink oracles. Adding CCIP is natural in that context. The unified security model simplifies reasoning about risk.

Interoperability between messaging protocols would be the endgame. Message sent via LayerZero, received via CCIP. We're not there yet but the abstraction layers are heading that direction.
