How Does the EIP-1559 Upgrade Affect the Determination of Gas Fees?

EIP-1559 introduced a mechanism where a portion of the transaction fee, called the "base fee," is algorithmically determined and burned (destroyed). Users also specify a "priority fee" (tip) to incentivize miners/validators.

This makes fee estimation more predictable and reduces volatility compared to the previous auction-style system.
