How Do Different Blockchain Consensus Mechanisms (E.g. PoW Vs. PoS) Handle Transaction Fee Distribution?

In Proof-of-Work (PoW) systems, like pre-Merge Ethereum or Bitcoin, the miner who successfully solves the block receives all the transaction fees. In Proof-of-Stake (PoS) systems, like post-Merge Ethereum, the validator who proposes and attests to a new block receives the transaction fees.

PoS often involves 'burning' a portion of the fees, reducing the amount distributed to the validator, which is a key difference from PoW.
