How Do Full Nodes Share Mempool Data to Improve Network-Wide Fee Estimation?

Full nodes constantly relay unconfirmed transactions and their associated fee rates to their peers across the network. This peer-to-peer sharing ensures that all nodes maintain a consistent, up-to-date view of the global mempool state.

Algorithms on each node use this shared, real-time data to calculate the current competitive fee rate for confirmation.
