Upgrade to ProLayerZero is a messaging protocol connecting 30+ blockchains. Unlike bridges that move assets, LayerZero sends arbitrary messages across chains. This enables 'omnichain' applications: tokens that exist natively on multiple chains (OFT standard), governance that aggregates votes across chains, and cross-chain DeFi. The protocol uses two independent entities (an Oracle and a Relayer) that must agree on a transaction's validity. This separation of concerns provides security without requiring a trusted setup for each chain pair.
