How Does the Base Fee Adjustment Mechanism in EIP-1559 Work?

The base fee adjusts automatically based on the network's utilization of block space. If the block is more than 50% full, the base fee increases for the next block to cool demand.

If it is less than 50% full, the base fee decreases to encourage usage. This adjustment happens in small, predictable increments to maintain fee stability.
