## Mempool Filtering

Mempool filtering is the process by which nodes in a decentralized network analyze pending transactions residing in the memory pool to determine which ones should be prioritized for inclusion in the next block. This practice involves evaluating transactions based on factors such as fee rates, complexity, and adherence to network policy rules.

By rejecting transactions that do not meet these criteria, nodes protect the network from spam and ensure that block space is utilized efficiently. This is a critical component of market microstructure, as it directly influences how transaction fees are priced and how quickly orders are executed in decentralized exchanges.

Effective filtering helps maintain network performance during periods of high volatility. It essentially acts as a gatekeeper that maintains the health of the blockchain by discarding low-quality or invalid requests before they consume computational resources.
