- The mempool is a copy of all unspent transactions and is present on all nodes.
- The mempool grows in size and transaction times can slow
- A larger mempool means that transaction times slow and in order to transact faster a higher fee is needed for miners to take the transaction and use it in a block.

What is the mempool?
The mempool is where valid transactions wait to be confirmed by the Bitcoin network. -
What happens if the miners can’t keep up with the rate of the new transaction?
If miners can’t keep up with the rate of the new transactions the nodes start prioritizing transactions by setting up a minimal transaction fee threshold. Transactions with a fee-rate lower than the threshold are immediately removed from the Mempool and only new transactions with a large enough fee are allowed access to the Mempool. (99bitcoins.com) -
How does a growing mempool effect transaction fees?
When the mempool grows the transaction fee increases.

1. What is the mempool?
A list of unconfirmed transactions that reside on each node. All mempools may not contain the same unconfirmed transactions due to incomplete network propagation.
2. What happens if the miners can’t keep up with the rate of the new transaction?
The transactions offering the highest fees get confirmed first.
3. How does a growing mempool effect transaction fees?
If a mempool is growing at a rate the miners can keep up with it likely won’t affect rates. As the list becomes bigger the Miner is forced to choose between transactions and will select those with the highest fees first.

-the mempool is a list of legitimate but unconfirmed transaction stored at each nodes. They are consulted by Miners in order to select the next transaction they will confirm and include into a block.
-the difficulty of mining decrease? Transaction with the lowest fee are rejected?
-The more transaction, the bigger the mempool, the more competation for transaction to being confirmed. In order to win the competition you need to increase the fees. So globaly, the effect of a bigger mempool is higher fees.

It increase an average waiting time for transaction to be put into a block, therefore you need to put a bigger fee in order to process your transaction quickly. So at the end transaction fees will get bigger and bigger.

The same as the answer from 2. (Mempool grows -> transaction fees grow)

No. Transactions remain in the mempool to be confirmed at a later time. Unless the mempool size reaches a certain limit set up by the node, at that point cheaper transactions start to get rejected.

The mempool is the list of all unconfirmed transactions.

If miners cannot keep up with the rate of new transactions, the mempool backlog increases along with the rate of new transactions.
-
A growing mempool results in higher transaction fees because there is more transactions that are competing attempting to be confirmed.

The mempool is a queue of unverified tx that have been pre-checked by a node. The node places the tx it sees fit in the mempool. From there the tx wait to be picked up and verified by a miner, which at that point is able to append it to the blockchain.
-
If miners can’t keep up with the rate of tx the mempool grows and wait times become longer.
-
A growing mempool will drive the tx fees up.

- it’s a list of all the transactions which are pending the “approval” of a miner who successfully validated/added a block of transactions from the mempool into the blockchain.
- The mempool grows in size and transactions take more time.
- Fees go up, because there is more competition for getting your transaction through, which normally, decreases the size of the mempool since “non essential” transactions are delayed until a time when fees settle lower.

If miners can’t keep up with the rate of new transactions then the mempool will increase in size, transaction times will potentially be longer.

A growing mempool will likely lead to an increase in transaction fees. Miners will pick transactions from the mempool with the highest fees, so if users want transactions to be confirmed quickly they would need to increase their fee, thus increasing the average fee cost.

A mempool is where an unconfirmed transaction is stored after being confirmed by a node that it is a valid transaction, where it waits for a miner to add it to the blockchain.
-
If miners can’t keep up with the mempool the mempool will grow and the time for a transaction to be added to the blockchain will be slower.
-
In a growing mempool the transaction that have the highest fees will be chosen first and the smaller ones will have a longer wait period and may result in people paying more to have their transactions done in a timely fashion.

The mempool is the node’s holding area for all the pending transactions. It is the node’s collection of all the unconfirmed transactions it has already seen enabling it to decide whether or not to relay a new transaction.
The number of unconfirmed transactions will increase in the mempool.
If the mempool is full, the fee market may turn into a competition: users will compete to get their transactions into the next block by including higher and higher fees . … A larger transaction will require a larger fee to be included in the next block. There is no simple way to calculate a transaction size by hand.

The mempool is a pool of unconfirmed transactions being passed to nodes around the network. Miners will gather mempools with higher byte sizes first, as. they are financially incentivized!

Growing mempools affect transaction fees because of the free market competition. By creating larger byte sized transactions (ie more inputs and outputs in your transaction) you create a larger fee (because fees are generated based off of byte size of transaction, not VALUE of BTC being exchanged). These larger fee TX’s will be prioritized by miners creating new blocks for the financial incentive, and smaller transactions will be remain in the mempool until a miner picks it up.
