     A **State** variable can be accessed throughout the contract. Functions inside a contract can call and use a state variable. This is known as `global scope`. A state variable is permanently stored in the contract. Variables `message` and `messageCount` in our code are state variables.

 - **Introduction to Airnode**: The Airnode is an architecture created by API3 to be the relay of data offchain bringing it onchain. There are two types of oracles:
 - A push oracle, where the data is sent to the blockchain constantly via a certain criteria. A price feed is a great example of a push oracle as we need to know the latest update of what the value of an asset is at any given time and need that onchain data immediately.
-- A pull oracle, where the data is requested at the time of need and we wait for a reponse of that request. A random number is a great example of how this would work. We need one for a mint, send the mint request wait for the request and once the data is received do some logic. This is a less time sensitive request.
