From a chain connector to an application-configured transport layer
LayerZero's V2 announcement on December 14, 2023 described an omnichain messaging protocol with endpoints, DVNs, Executors and an X-of-Y-of-N security model. Its current documentation describes source and destination endpoints, per-channel nonces, message libraries, verification and destination execution.
The model is intentionally modular: applications choose required and optional DVNs and thresholds. That makes LayerZero less like one bridge with one validator set and more like a transport layer whose security depends on the OApp's selected stack and the underlying chains and operators.
