What is Gas?

"Gas" is the name of a special unit used in smart contract-enabled blockchain networks. It measures how much "work" an action or set of actions requires to perform. For example, to calculate a Keccak256 cryptographic hash, it takes 30 gas each time the hash is computed, plus another 6 gases for every 256 bits. data is hashed. Every transaction that can be performed with a transaction or contract on the platform has a certain amount of gas cost, and operations that require more computational resources will cost more gas than operations that require fewer computational resources.
