Gas fee is a commonly used term for the cost that certain blockchain protocol users pay to network validators each time they wish to perform a function on the blockchain.
Gas serves as an incentive for network validators to record transactions accurately and behave honestly in the upkeep of the protocol.
While Ethereum and Polygon use the term “gas fees,” other blockchains such as Solana and Bitcoin use the term “transaction fees.” “Gas” comes from the fee’s similarity to the fuel which keeps a vehicle running.
