In EIP-1559, every transaction fee is composed of both a base fee and a miner tip. The base fee is burned, and the miner tip is paid to a block's miner. The miner tip equals the gas used in a transaction * minimum(miner tip, fee cap - base fee). The miner tip is essentially a small bribe to miners in order to incentivize the inclusion of transactions with the largest tip into a block. "Miner Tip" is a visual representation of an ETH tip between users and miners with the ETH symbol containing the exact miner tip formula code from go-ethereum.
