Mempool is a database structure that exists on full nodes, it hold all verified but unconfirmed transactions, which means they not yet written to a block within the block chain.
-
If miners can’t keep up with the mempool, that means transactions will take longer to be confirmed on a block.
-
When mempool is growing that’s creates a higher competition between transactions and the higher the miner are being incentivized by fees the faster that transaction is to be processed.

- Mempools are ‘pools’ of unconfirmed transactions on the blockchain
- The mempool will begin to fill, ultimately leading to longer transaction wait times, especially if the fee is small
- A growing mempool will effect transaction fees because the miner will select the transactions with the highest fees first, resulting in a rise in fees in order to have transactions process more quickly

What is the mempool?
list of valid but unconfirmed transactions sitting in a list on a node waiting for miners to add to blockchain
What happens if the miners can’t keep up with the rate of the new transaction?
the Mempool list grows longer and longer and or people offer more fees to get their transactions confirmed or wait longer time period to confirm transactions
How does a growing mempool effect transaction fees?
becomes more expensive to make transactions, people will have to offer more fees to get their transactions confirmed, and the market for fees will boom, miners own market

1: A mempool consists of all unconfirmed transactions that any given node has received, checked, and made sense to that node. Each node has its own mempool which may differ slightly depending on which transactions they have received.
2: Then transactions will, on average, take longer to process.
3: As the mempool increases, fees will start to increase in order to incentivize more miners to enter.

The mempool is a list of unconfirmed transactions that is held by all nodes on the network. A new unconfirmed transaction only gets put into the mempool if it makes sense. Miners take these transactions from the mempool and add them into new blocks.

This will create longer wait times for transactions.
-
Transaction fees increase because miners will choose the transactions with the highest fees first.

1, Mempol stores unconfirmed transactions until it is picked up by miners.
2. If your fee is low it will take longer for the miner to pick it up and as the mempol grows it takes even longer.
3. A growing mempol would increase the transaction fees.

What happens if the miners can’t keep up with the rate of the new transaction?
The mempool will grow bigger. Unconfirmed transactions will not be confirmed and will be rerturned.

A growing mempool will cause transaction per byte to increase because miners will choose the higher transaction fees to mine first.

How does a growing mempool effect transaction fees?
miners can choose the txn that gives the highest fees. And whoever offers the higer fee will get their txn picked up first.
Can someone answer these Question please ? if possible.
How many satoshi/byte can there be in the next block ? Averagely how many transactions are there in the next block created ? Or is it just one new txn in the next block?
Because if it is several txns in the next block, that means not just one miner created the block, but rather all the miners who mined the several other txns, also helped create the next block ?

1- A list of unconfirmed transactions that have been verified by the nodes that are yet to be added to a block by the minors.
2- Transaction time will increase
3- Fees will go up as there is more competition to be in the next block. Minors will pick the transactions with the highest fees.

A block can have 1MB of transactions. I have never done any approximations how many tx fit in one block, it varies on the complexity of transactions.
A miner builds a block with tx from its own mempool and then begins to mine it, they don’t help each other but compete which one will mine the block fastest to get the mining reward.
