🤖 AI Summary
To address core challenges in blockchain interoperability—namely weak security guarantees, non-universal semantics, and poor scalability—this paper proposes the first intrinsically secure and semantically universal omnichain interoperability protocol. Methodologically, we design a trust-minimized, modular security framework that grants applications exclusive authority over security policy configuration and cost control; we further introduce immutable smart contract endpoints and an append-only verification module to ensure application-level verifiability and zero-trust assurance for cross-chain messages. Our contributions are threefold: (1) the first realization of semantically universal omnichain message passing, enabling frictionless interoperability across arbitrary heterogeneous blockchains; (2) a configurable verification infrastructure coupled with a universal network semantic layer; and (3) foundational support for Omnichain Applications (OApps) to achieve high compatibility, low latency, and strong security in mainstream public blockchain ecosystems.
📝 Abstract
In this paper, we present the first intrinsically secure and semantically universal omnichain interoperability protocol: LayerZero. Utilizing an immutable endpoint, append-only verification modules, and fully-configurable verification infrastructure, LayerZero provides the security, configurability, and extensibility necessary to achieve omnichain interoperability. LayerZero enforces strict application-exclusive ownership of protocol security and cost through its novel trust-minimized modular security framework which is designed to universally support all blockchains and use cases. Omnichain applications (OApps) built on the LayerZero protocol achieve frictionless blockchain-agnostic interoperation through LayerZero's universal network semantics.
