Key Components of LayerZero
When you explore LayerZero, you'll discover its key components that facilitate seamless inter-blockchain communication.
Immutable Endpoints serve as the backbone of this system, ensuring censorship resistance and message immutability while managing message delivery. Each endpoint is deployed on connected blockchains and generates unique packets for cross-chain transactions. This process utilizes unique packet generation with sequential numbering (nonce) to ensure proper message transmission.
The MessageLib Registry boosts security by registering verification libraries and utilizing immutable modules to prevent vulnerabilities.
Decentralized Verifier Networks (DVNs) independently verify messages using advanced technologies, enhancing accuracy.
Lastly, Permissionless Executors commit verifications and call the 'lzReceive' function to process validated packets off-chain.
Together, these components create a reliable framework for executing cross-chain transactions without central control, ensuring a robust inter-blockchain communication experience.
