No, this is the same fuel that you put into your automobile! The terms "Gas" or Gas Fee grew popularity in the blockchain space from the Ethereum Network. Gas is the fuel that allows Ethereum to operate, in the same way that a car needs gasoline to run.
A gas fee refers to the fee required to conduct transactions or execute contracts on the Etherum network. On the Ethereum Network gas fees have to be paid in Ethereum's native digital reward, ether (ETH). Gas prices are usually quoted in gwei, (The denomination used in defining the cost of gas) which is a denomination of ETH. Each gwei is equal to one-billionth of an ETH (0.000000001 ETH or 10-9 ETH).
A gas fee represents the specific amount of Ether (ETH) needed for a user to perform a transaction on the Ethereum blockchain network. It serves as the cost associated with executing operations or running smart contracts on the network.
Gas Fee's have been adopted in many blockchain projects and the term is used for rewards for the transaction to occur, that may or may not be in their own native digital reward or in an alternate digital reward like ETH.
