Gas fees are the fees required to process transactions or run smart contracts on a blockchain network like Ethereum. These fees are paid to validators as compensation for the computing resources they provide to maintain the security and efficiency of the network. The amount of gas fees can fluctuate based on network demand; when the network is congested, fees tend to increase, and vice versa. Additionally, transaction complexity also affects the amount of gas required; more complex transactions require more gas, resulting in higher fees. Understanding the gas fee mechanism is important for users to optimize costs and efficiency in transacting on the blockchain.
