How Does RBF Allow a User to Effectively ‘Unstick’ a Low-Fee Transaction?

RBF allows a user to 'unstick' a low-fee transaction by creating a new, identical transaction (same inputs and outputs) but with a significantly higher fee. This new, higher-fee transaction is then broadcast to the network.

Since miners are incentivized by profit, they will prioritize the version with the higher fee and include it in a block, simultaneously invalidating the original low-fee transaction. This mechanism allows the user to dynamically adjust their fee to compete in a congested market without waiting for the original transaction to be dropped.
