#以太坊 #ETH - Mempool memory pool

Ethereum’s mempool is a temporary storage area used to store all pending transactions. When you initiate a transaction, the transaction first goes into the mempool and waits for miners to add it to the next block. Miners select the transactions they mine based on transaction fees (Gas fees), and generally speaking, transactions with higher fees are prioritized. Therefore, transactions in mempool may wait for different amounts of time to be processed depending on network congestion and transaction fees.

Imagine that Ethereum is like a giant computer that can process transactions sent by many people. When you want to send a transaction (such as transferring money to a friend), the transaction is like an envelope and you put it into a giant mailbox (mempool). There may already be envelopes from many other people in this mailbox. Then, the postman (miner) will come to this mailbox, take some envelopes, and deliver them to their destination. However, the postman can only take a certain number of envelopes at a time, so if there are too many in the mailbox, your envelope will have to wait a while before it can be delivered.

Key points of mempool:

What is mempool: an area where pending transactions are stored.

Function: Help users view their transaction status and provide mineable transactions for miners.

How transactions enter mempool: When a user initiates a transaction, the transaction first enters mempool.

How transactions are mined from the mempool: Miners select the transactions they want to mine, usually based on transaction fees.

Impact of network congestion: When the network is congested, transactions in mempool may need to wait longer to be processed.
