In simple terms, LayerZero provides interoperability between blockchains, without the use of traditional cross-chain bridges and wrapped tokens, and most importantly, does not require trust when verifying cross-chain transactions. Let's consider the main advantages of this protocol:

Ease of development. Decentralized applications based on LayerZero have only two functions - sending and receiving data. Creating such an application for a developer will only require knowledge of languages ​​such as Solidity, Rust, etc. Since there are no intermediaries in this system, two completely different blockchains can interact with each other without restrictions.

Protocol potential. As the name of the protocol suggests, LayerZero is a low-level infrastructure that can be used by cross-chain liquidity aggregators, yield aggregators, lending protocols and any other decentralized applications (dApps) running on multiple blockchains.

The main component of the protocol is the endpoints “Endpoints”, located in connected blockchains and representing a series of smart contracts. Once such a smart contract is deployed on the desired blockchain, they cannot be changed or stopped, ensuring an unchanging data flow.

To transfer data between endpoints, LayerZero uses relays and oracles. When sending from one blockchain to another, the endpoint on the source blockchain notifies the relay and the oracle about the message and the endpoint on the destination blockchain. The oracle then sends the corresponding block header to the target blockchain endpoint, and the relay confirms the transaction.
