The mempool matters.

Every second, tens of thousands of pending transactions battle for block space. So each blockchain transaction competes in the mempool to be confirmed as quickly as possible – and for the lowest fee.

All transactions move through the mempool.

The mempool contains all possible future block states.

Mempool data is pre-consensus, ever-changing, and thin.
