Gas Fees
Transaction fees paid to validators/miners for executing operations on a blockchain.
In-Depth Explanation
Gas measures computational effort. Users pay gas fees (gas used × gas price) to incentivize block producers to include their transactions. Ethereum gas fees vary with network congestion. High gas fees were a major driver of L2 adoption. Post-EIP-1559, a portion of ETH gas fees is burned.
