  The mempool, short for memory pool, plays a crucial role in the blockchain network. It is a temporary storage area where pending transactions are held before they are included in a block and added to the blockchain. When a transaction is initiated, it is first broadcasted to the network and enters the mempool. Miners then select transactions from the mempool to include in the next block they mine. The mempool acts as a waiting area for transactions, ensuring that they are valid and ready to be processed by miners. Transactions in the mempool compete for limited block space, and the priority of inclusion is determined by factors like transaction fees and size. Once a transaction is included in a block, it is removed from the mempool and becomes a permanent part of the blockchain.

  The mempool is like a queue where transactions wait to be confirmed and added to the blockchain. It acts as a temporary holding area for pending transactions, ensuring that they are valid and ready to be processed. Miners select transactions from the mempool based on various factors such as transaction fees and size. Transactions with higher fees and smaller sizes are usually prioritized for inclusion in the next block. Once a transaction is included in a block, it is removed from the mempool, and the process continues for the remaining transactions in the mempool.

  In the blockchain network, the mempool serves as a temporary storage space for pending transactions. When a user initiates a transaction, it enters the mempool and waits to be confirmed by miners. Miners select transactions from the mempool based on their own criteria, such as transaction fees and size. The mempool acts as a competitive space, where transactions compete for limited block space. Once a transaction is included in a block, it is removed from the mempool and added to the blockchain. The mempool ensures that transactions are processed in a fair and efficient manner, while also allowing users to track the progress of their transactions.
