Gas Fees
Gas fees are the cost paid to process transactions on blockchains like Ethereum.

Transaction Fee. Varies. Rewards Validators.
Expanded Explanation:
On blockchains that run smart contracts, every action from sending ETH to mining an NFT requires computing power. Gas fees compensate the network participants who provide that power. When demand is high, fees rise because users compete to have their transactions processed faster. These fees can be frustrating where costs sometimes spike. Some blockchains try to compete by offering specifically lower fees.
