How Does a Transaction’s “Replace-by-Fee” (RBF) Feature Attempt to Reduce Latency?

Replace-by-Fee (RBF) allows a user to submit a new version of an unconfirmed transaction with the same nonce but a significantly higher transaction fee. The original, lower-fee transaction is then dropped by nodes, and the new, higher-fee version is prioritized by miners/validators.

This effectively lets the user "bid up" their fee to accelerate inclusion, thereby reducing the latency of the transaction's confirmation.
