Ethereum Gas refers to the fee required to conduct transactions or execute smart contracts on the Ethereum network. It serves as a compensation for miners or validators who process and verify transactions.Gas is measured in units called “gwei,” which is a fraction of Ether (ETH), the native currency of Ethereum. When a user wants to perform an action, they specify a gas limit (the maximum amount they are willing to spend) and a gas price (the amount they are willing to pay per unit of gas). The total fee a user pays is calculated by multiplying the gas limit by the gas price. If the network is busy, gas prices can increase due to higher demand, and users may need to pay more to get their transactions processed quickly.Gas ensures that the network operates efficiently, discouraging spam and ensuring that only meaningful transactions are executed. Understanding gas helps users make informed decisions regarding their transactions and manage their costs effectively.
