Glossary
This glossary defines and explains many LayerZero concepts and terminology.
- the UA that send() the message at the source chain as srcUA, (srcChain, srcAddress)
- the UA that lzReceive() at the destination chain as dstUA, (dstChain, dstAddress)
In Layerzero's perspective, srcUA and dstUA are different, though they might be the same entity.
ULN is a messaging protocol, firstly introduced in the LayerZero white paper, that allows lightweight cross-chain messaging with configurable trustlessness on the specification of Oracle and Relayer, the two roles that are relaying block information and transaction proof across chains.
A contract address that can be notified to move a block header.
Any process that delivers a transaction proof in the LayerZero system.
The contract that handles the message payload packing on the source chain and verification on the destination chain. Ultra-Light Node is an implementation of Messaging Library
The contract that verifies the validity of a proof. Merkle Patricia Tree inclusion proof is an implementation of Proof Library.
