How Does the Mempool Size Fluctuate and What Does It Indicate about Network Congestion?

The Mempool size is the total number or total size of unconfirmed transactions waiting across the network. It fluctuates based on network demand and the rate at which blocks are mined.

A rapidly increasing Mempool size indicates high network congestion, meaning there is more demand for block space than the network can currently process. Conversely, a shrinking Mempool suggests the network is clearing the backlog, leading to lower fees and faster confirmations.
