The Chain IDs in the Wormhole context are
u16integers that map to chains. Note these Chain IDs are not the same as other Chain IDs used for things like wallets.
A Delivery Provider performs the service of watching for Wormhole Relayer delivery requests and performing the delivery to the intended target chain as instructed
The contract that calls the Wormhole Core contract. It's address is included in the message published and a sequence number for the message is tracked to provide a unique id.
The Finality of a transaction is dependant on the blockchain properties. After a transaction is considered final, it can be assumed the state changes it caused won't be rolled back.
Validators that exist in their own P2P network that serve as Wormhole's oracle by observing activity on-chain and generating signed messages attesting to that activity.
The Guardian Set is a set of guardians that are responsible for validating a message emitted from the core contracts. Occasionally the members in the set will change through a governance action.
Each Guardian will issue a
Heartbeaton a 15s interval to signal that it is still running and to convey details about its identity, uptime, version, and status of the connected nodes.
An Observation is the data structure that describes a message that was emitted by the Core Contract and noticed by the Guardian node.
A Relayer is any process which delivers VAAs to a destination.
A nonce, strictly increasing, tracked by the wormhole core contract and unique to emitter chain and address
A Spy is a daemon that eavesdrops on the messages passed between Guardians, typically to track VAAs as they get signed.
A daemon that is configured to monitor a blockchain node and observe messages emitted by the wormhole contracts.
Term that refers to the full range of cross-blockchain interoperability.
Chain-and-path agnostic token that exists on a layer outside the blockchain ecosystem, which can be used to conduct transactions on any blockchain.
Decentralized application that enables users to create and/or use xData.
Data that exists in a layer outside of Layer 1 blockchains, which is accessible by all chains.
