LayerZero is an omnichain protocol that aims to enable cross-chain communication between different blockchains without the need for third-party intermediaries, thereby providing a smoother and more secure cross-chain interaction experience.

The core operating principle of the protocol is based on three main components: Endpoint, Oracle, and Relayer.

1.Endpoint: LayerZero deploys a set of smart contracts on each supported blockchain. These smart contracts are responsible for connecting all supported blockchains and can easily integrate new blockchains into the LayerZero network. Through these endpoints, different blockchains can communicate and interact with each other without the use of cross-chain bridges or other complex solutions.

2. Oracle: An oracle is a third-party service whose role is to transmit data from one blockchain to another, usually block header information. These data transmissions are to ensure the synchronization and correctness of each chain.

3. Relayer: The main task of the relayer is to obtain proof of a specified transaction and propagate its verification to other chains. According to the design of LayerZero, anyone can become a relayer, which makes the entire system more decentralized and secure.

LayerZero's overall design makes it similar to a universal blockchain translation mechanism, making asset exchange and application use across multiple blockchains simpler and more efficient. Through the collaboration of endpoints, oracles, and relayers, LayerZero ensures secure, fast, and reliable cross-chain interactions, which is why it is considered one of the most anticipated airdrop projects.
