Gas Fee

The fee paid to compensate blockchain validators for the computational resources required to process and confirm a transaction — denominated in the blockchain's native currency.

On the Ethereum network, "gas" is the unit measuring the computational effort required to execute a specific operation. Every transaction — from a simple ETH transfer to a complex DeFi interaction — consumes a specific amount of gas. The gas fee paid equals gas used multiplied by the gas price, denominated in gwei (a fraction of ETH). Users set their gas price; higher gas prices mean miners/validators prioritize your transaction faster.

Ethereum's EIP-1559 upgrade (August 2021) introduced a base fee — a minimum fee that automatically adjusts based on network demand — plus an optional tip to validators. The base fee is burned (destroyed), making ETH deflationary when the network is heavily used. Gas fees on Ethereum mainnet can range from under $1 during quiet periods to $50–200+ during periods of intense demand (like NFT mints or market crashes when everyone tries to transact at once).

High gas fees have driven activity to Ethereum Layer 2 networks (Arbitrum, Optimism, Base) and alternative blockchains (Solana, Avalanche) that offer much lower fees. Bitcoin also has transaction fees, though they work differently — users pay a fee per byte of transaction data, denominated in satoshis. Bitcoin fees have spiked significantly during periods of high network activity, particularly around ordinals/inscriptions activity in 2023–2024.
