Gas fees are essential costs for executing transactions on Ethereum, compensating validators for their computational work. Measured in Gwei, these fees ensure network security and prevent spam. The London Upgrade improved fee calculation, introducing a base fee that burns tokens, enhancing ETH's utility.

Gas fees represent the cost that users must pay to execute transactions on blockchain networks like Ethereum. These fees function as compensation for the computational resources and energy required to process and validate each transaction on the network. Think of gas fees as the operational expense necessary to keep decentralized networks running smoothly—without them, there would be no incentive for validators to maintain the blockchain.

What Are Gas Fees and Why Do Users Pay Them?

When you perform any operation on the Ethereum blockchain, from sending tokens to interacting with smart contracts, you’re consuming network resources. Gas fees compensate network validators for this computational work. Users pay these fees in ETH, Ethereum’s native cryptocurrency. Without gas fees, the network would be vulnerable to spam and denial-of-service attacks, making it economically rational for participants to submit transactions only when they’re willing to pay for the resources consumed.

From ETH to Gwei: Understanding Transaction Costs

Gas fees on Ethereum are typically measured in Gwei, a smaller denomination of ETH where 1 Gwei equals 0.000000001 ETH. This measurement system allows users and developers to work with more practical numbers when discussing transaction costs, rather than dealing with extremely small fractions of ETH. The base fee, priority fee, and maximum fee per gas are all denominated in Gwei, making this unit essential for anyone participating in the Ethereum ecosystem.

How the London Upgrade Transformed Gas Fee Calculations

The Ethereum network underwent a significant transformation in August 2021 with the London Upgrade, which fundamentally changed how gas fees are calculated and burned. Prior to this upgrade, gas fees operated on a simple auction model. The London Upgrade introduced the concept of a base fee that burns tokens out of circulation, creating a deflationary mechanism. This change not only made fee estimation more predictable but also gave ETH additional utility beyond being merely a medium of transaction—it became a store of value as fees are permanently removed from supply.
