  1. Its a place where all the transaction which are still unspent are collected.
  2. It will be transacted in one of the next blocks. Mepmpool grows.
  3. The Mempool is getting larger and more filled. So the transaction fees are getting higher because more worthful transactions will be transacted first.

01 What is the mempool?
The mempool is a data store in each node which contains all unconfirmed transactions that were received by that node.
02 What happens if the miners can’t keep up with the rate of the new transaction?
The more transactions that get created and broadcast to the network, the more storage is required in the mempool. If the miners cannot keep up with the rate of new transactions, the mempool storage will keep growing.
03 How does a growing mempool effect transaction fees?
It does not! According to my understanding, the transaction fee is dependent on the size of the transaction in bytes and not the size of the mempool itself.

addendum to answer 3: If transactions with low fees take a long time to process, eventually what may end up happening is that they will be transacted at a higher fee at the discretion of the sender. This is nevertheless an indirect implication of an impact on fees.

  1. The mempool is a sort of waiting room for unconfirmed transactions.

  2. The mempool will become larger what will increase the transaction time and probably the transaction fees will become more expensive.

  3. The minors will process the transactions with higher gas fees first, so this will cause a raise in transaction fees, otherwise people will stay in a waiting line for a very long time.

The mempool, This is where transactions are stored within each node until it has received enough confirmations to validate it onto the blockchain.

The number of unconfirmed transactions will increase in the mempool.

A growing mempool increases transaction fees because miners are incentived to choose transactions that offer them the highest fee in return for appending the transaction onto the blockchain.
Miners can neglect lower fees until they have mined through the higher bids

  1. What is the mempool?

A me pool is a group of nodes broadcasting transactions pending verification and validation by a miner.
2. What happens if the miners can’t keep up with the rate of the new transaction?
Transactions can pile into a mempool , being rebounced to more nodes , increasing the size of the mempool. The transactions might be taking more time under these circumstances.
3. How does a growing mempool effect transaction fees?
A growing mempool will lead to a longer confirmation process. As miners always select highest fees transactions , fees might increase.

What is the mempool?
During wallet construct a new transaction and sent to other nodes to verify.It will be state “unconfirm”.
At state ‘unconfirm’ that waiting miner pick this transaction to add into the blockchain, it will put in the special place call
“mempool”.So, basically mempool is data structure that each node has.(List of unconfirm transaction on each node)
and then miner will check all transaction from it own local copy of mempool and pick the transaction with the highest fee because miner want to get money

What happens if the miners can’t keep up with the rate of the new transaction?
The list of unconfirm transaction in mempool will keep growing and delay process to state “confirm”.

How does a growing mempool effect transaction fees?
The transaction fee go up because the miners will choose the transaction with the highest fee first.

Mempool is a place that unconfirmed transactions wait for miners
If miners can not keep up the mempool gets larger which makes longer transaction times
Transaction fees increase with a larger mempool because of competition to get the next block so larger fees are offered to get transaction first

Mempool is where each node participating in the network put uncomfirmed transactions.

If the miners cant keep up with the rate of new transactions then the mempool grows and the transaction times can blow out.

A growing mempool can mean that miners are likely to give preference to transactions with larger fees attached.
