Gas is a fundamental concept in the Ethereum blockchain, representing the computational effort required to execute transactions and run smart contracts. Each operation on the Ethereum network, whether it is a simple transaction or a complex smart contract, requires a certain amount of gas to be performed. Users pay for gas using Ether (ETH), the native cryptocurrency of Ethereum, which incentivizes miners or validators to process and validate these operations. The gas system helps manage the network's resources, prevent spam, and ensure that transactions are prioritized based on their gas price, which is the amount users are willing to pay per unit of gas. This mechanism allows for a flexible and efficient way to allocate computational power, maintain network security, and ensure fair usage of the Ethereum blockchain.
