LayerZero is a trustless cross-chain communication protocol that uses ultra-light node technology and a combination of relayers and oracles to balance the security and cost of cross-chain communication.
Light nodes and ultra-light nodes
Light nodes are a node mode that stores block headers instead of complete transaction information and verifies the existence of transactions through Merkle trees. Ultra-light nodes (ULN) further simplify and verify transactions by streaming block header data to reduce costs.
LayerZero's cross-chain core roles
1 Oracle and Relayer
Oracle, as an oracle, tells the target chain contract when to verify and the verification results; Relayer provides the proof and specific cross-chain information required for verification.
2 Division of work between Oracle and Relayer
The oracle transmits the source chain block information to the target chain, while the relayer transmits cross-chain messages and verification paths to ensure the security and accuracy of the information.
3 LayerZero's cross-chain life cycle
The detailed process from user-initiated transactions to cross-chain information verification and execution involves multiple steps such as communicators, validators, network layers, and relays to ensure the smoothness and security of the entire cross-chain process.
Evaluation of the advantages and disadvantages of the LayerZero protocol
Advantages
