A mempool (short for "memory pool") the queue of pending and unconfirmed transactions for a cryptocurrency network node. There is no one global mempool: every node on the network maintains its own mempool, so different nodes may hold different transactions in their mempools.

The first miner on the network to find a suitable block earns all the transaction fees from the transactions in that block. As a result, miners tend to prioritize transactions with higher transaction fees.
+Mining is the process by which unconfirmed transactions in a mempool are confirmed into a block on a blockchain. Miners select unconfirmed transactions from their mempools and arrange them into a block such that they solve a particular math problem.
The first miner on the network to find a suitable block earns all the transaction fees from the transactions in that block. As a result, miners tend to prioritize transactions with higher transaction fees.
When a Bitcoin transaction is made, it is stored in a Bitcoin node's mempool before it is confirmed into a block. When the rate of incoming transactions exceeds the rate transactions are confirmed, the mempool grows in size.
The default maximum size of a Bitcoin node's mempool is 300MB, so when there are 300MB of transactions in the mempool, we say it's \"full\".
