Gas metering refers to the process of measuring the amount of computational work required to execute operations on a blockchain, particularly for smart contracts. Each operation consumes a certain amount of “gas,” which is a unit of measurement used to quantify the computational effort.When users initiate a transaction or interact with a smart contract, they must specify how much gas they are willing to spend. This limit determines how many operations can be performed and ensures that the network’s resources are utilized efficiently. If the gas runs out before the transaction is complete, it fails, but the user still pays for the gas already consumed.Gas prices can fluctuate based on network demand. Higher fees incentivize miners to prioritize certain transactions, especially during peak usage times. Understanding gas metering can help users manage their transaction costs effectively and ensure that their operations are executed in a timely manner. Overall, gas metering plays a crucial role in maintaining network performance and fairness among users.
