Mining & GAS
Gas refers to the fee, or pricing value, required to successfully conduct a transaction or execute a contract on the Ethereum blockchain platform. Priced in small fractions of the cryptocurrency ether (ETH), commonly referred to as gwei and sometimes also called nanoeth, the gas is used to allocate resources of the Ethereum virtual machine (EVM) so that decentralized applications such as smart contracts can self-execute in a secured but decentralized fashion.
Gas, on the Ethereum network, measures the amount of computational effort required to perform transactions through the network. Think of Gas similar to how fuel allows a car to drive. Gas fuels any type of transaction on the Ethereum blockchain.
