EIP-1559 introduced a fee-market mechanism with a base fee adjusted from block demand and a separate priority payment. The base fee is burned rather than awarded to the block producer. Transactions specify a maximum total fee per gas and a maximum priority fee, allowing wallets to express a ceiling without automatically paying that entire ceiling. The specification also permits temporary variation around a target level of block gas usage, rather than treating every block as an identical fixed-capacity auction.

If blocks use more execution gas than the mechanism's target, the base fee rises; below-target usage pushes it down. The adjustment depends on prior block usage, so an application's estimate can reason about the next step rather than guessing an unconstrained new auction price. Consider a transaction whose total cap no longer covers the next block's base fee: it waits or must be replaced under relevant node policies. Increasing the cap authorizes a larger possible price, but does not make contract execution itself require fewer gas units.

The mechanism did not eliminate congestion or guarantee cheap transactions. Scarce block resources can still command high fees, and contract complexity still affects gas consumption. Burning fees also does not guarantee that ETH supply decreases over every period: issuance and aggregate activity matter. For research, separate the specification's fee rules from claims about token valuation or investment performance. Compare actual gas usage, effective prices, burned fees, and issuance using clearly defined periods rather than treating the existence of a burn as a complete economic conclusion.
