Definition 14.6 Markets III: Commodities, Energy and Crypto · Chapitre 14 — Blockchains for Traders

Gas is the unit in which Ethereum measures the computation and storage a transaction uses; each block has a gas limit. A transaction pays, per unit of gas, the block’s base fee, which is burned and set by protocol, plus a priority fee (a tip) that it chooses and that goes to the block’s proposer.

A demand shock under EIP-1559: from block 5 to block 34 demand for gas is four times higher. Blocks fill, the base fee rises 12.5% a block until demand falls back to the target (half the limit), and decays when the shock ends. Illustrative demand; exact protocol arithmetic. Data: the chapter’s tutorial.
