Blockchain·2yGas Fees In Ethereum: How Transactions Are Powered
Gas is a unit that measures the computational effort needed for operations on the Ethereum network, such as transactions and smart contract execution. Users pay gas fees in Ether (ETH) to incentivize miners or validators. The gas limit is the maximum amount of gas a user will spend, while the gas price is the amount of ETH paid per unit of gas. High gas fees can lead to delays and higher costs during congestion, while Ethereum 2.0's shift to Proof of Stake and sharding aims to make transactions faster and cheaper.
