The #mempool, short for "memory pool," is a temporary storage area in the Bitcoin network where valid, unconfirmed transactions reside before being added to a block by miners.
It acts as a waiting area for transactions awaiting confirmation, containing a backlog of pending transactions. Miners prioritize transactions based on factors like transaction fees and size.
Transactions with higher fees are typically included in blocks first. The mempool's size and congestion fluctuate depending on network activity.
Transactions may be delayed if the mempool is congested, leading to longer confirmation times and potentially higher fees for faster processing.
