How Does a Miner Choose Which Transactions to Include from the Mempool?

Miners typically prioritize transactions offering the highest fee-per-byte (or gas price). Their goal is to maximize the profit from the block reward and transaction fees.

They also check that the transaction is valid and has not been double-spent. The miner's choice is a competitive economic decision, leading to a dynamic fee market.

This selection process determines the order and speed of transaction confirmation.
