## EIP-1559 Base Fee Mechanics

EIP-1559 introduced a fundamental change to the fee structure of the Ethereum network by implementing a dynamic base fee that is burned. This mechanism aims to make transaction fees more predictable and less reliant on user-submitted bids.

The base fee increases or decreases automatically based on the network's congestion relative to a target block size. This design ensures that users only need to pay a small priority fee to incentivize validators, while the base fee helps regulate demand.

For derivative protocols, this provides more stability in transaction cost forecasting. It also creates a deflationary pressure on the network's native asset.

The introduction of EIP-1559 significantly altered the economic landscape for all participants on the network.
