 === Transaction Pools
 
-. ((("bitcoin network", "transaction pools")))((("transaction pools")))Almost every node on the bitcoin network maintains a temporary list of unconfirmed transactions called the _memory pool_, _mempool_, or _transaction pool_. Nodes use this pool to keep track of transactions that are known to the network but are not yet included in the blockchain.
