Gas

Gas is a unit that measures the computational effort required to execute transactions or smart contracts on the network. Each operation within a transaction consumes a specific amount of gas, and users pay gas fees in Ethereum (ETH) to incentivize miners to include their transaction in a block.

The gas price, typically set by the user, determines the transaction's priority: higher prices attract faster processing. This mechanism ensures that complex or resource-intensive operations are fairly compensated while preventing spam and inefficient use of the network. By aligning incentives, gas keeps the Ethereum ecosystem efficient, secure, and continuously operational.
