What is Gas?
Gas is a unit that measures the amount of computational effort required to execute operations on the Ethereum network. Every transaction or smart contract execution on Ethereum requires computational resources, and gas is the fee paid to compensate validators for these resources.
Prevents Spam: By requiring a fee for every transaction, gas helps prevent spam and ensures that the network isn’t clogged with unnecessary transactions.
Incentivizes Validators: Validators, who are responsible for verifying and processing transactions, receive gas fees as a reward for their work. This incentivizes them to maintain and secure the network1.
Regulates Network Demand: Gas prices fluctuate based on network demand. When the network is busy, gas prices increase, which helps manage the load on the network2.
