What is the BitCoin Mempool?

The BitCoin mempool (short for memory pool) is a collection of all unconfirmed transactions on the BitCoin network. When a transaction is made, it is first broadcasted to the BitCoin network and enters the mempool, where it waits to be confirmed by miners and added to the blockchain. The mempool serves as a waiting area for transactions and acts as a bottleneck for transaction processing speed.

How does the mempool work?

When a transaction is made, it is sent to a node on the BitCoin network. This node then verifies the transaction and adds it to its local mempool. The transaction is then propagated to other nodes on the network and added to their mempools as well. This process continues until the transaction is added to all the nodes’ mempools.

Why is the mempool important?

The mempool plays a crucial role in the BitCoin network as it determines which transactions are included in the next block to be added to the blockchain. Miners prioritize transactions with higher transaction fees, so transactions with lower fees may take longer to be included in a block. The size of the mempool can also give an indication of network congestion and the current transaction fee market.
