What Is the ‘Mempool’ and Its Function in Cryptocurrency Transactions?

The Mempool (Memory Pool) is a staging area for unconfirmed transactions that have been broadcast to the network but have not yet been included in a block by a miner. Its primary function is to hold and validate these transactions, allowing miners to select the most profitable ones (typically those with the highest fees) to include in the next block.

It acts as a backlog for network activity.
