How Does the Concept of ‘Fee Market’ Differ in PoW versus PoS?

In PoW, the fee market is a pure auction where miners select transactions based on the highest fee per unit of gas/weight. In PoS, while an auction element exists, the mechanism is often integrated with staking protocols and may include fee burning (like Ethereum post-Merge).

PoS validators are selected pseudo-randomly, which slightly reduces the direct competitive pressure of the PoW auction.
