gas-fees
The fee required to verify and process a transaction on a blockchain network.
Gas fees are payments made by users to compensate for the computing energy required to process and validate transactions on the blockchain. Just as a car needs gas to run, smart contracts need 'gas' to execute code. The distinct 'Gas Limit' determines the maximum work allowed, while 'Gas Price' determines the cost per unit of work.

Think of the [blockchain](/en/terms/blockchain) like a busy toll highway. To drive your car ([transaction](/en/terms/transaction)) from A to B, you have to pay a toll. If the road is empty, the toll is cheap. If it's rush hour and everyone wants to drive, the toll goes up, and you have to bid higher to get on the road first.
