- The mempool is the aggregate of all unconfirmed transactions in a node.
- The mempool grows and transaction speeds decrease if the miners can not keep pace with increasing transactions.
- Transaction fees will increase because people will incentivize miners with higher fees to decrease transaction time.

Answers to the “Mempool” Questions:
-
It is a list of transactions that still needs to be processed, but the node is not ready yet to process these transactions. So they will be added to the Mempool.
-
Then these new transactions will be added to the Mempool.
-
Miners want to make the most money out of every unit of work. So they might process the transaction with the best fees first.

- A Mempool is a waiting area for Bitcoin Transactions.
- Transaction’s will be delayed in getting put into the block chain.
- The larger the sat/B the larger the fee thus these will be the first transaction’s the minors will transact.

1- is the list where validated unconfirmed transactions stand in a node. Every node has its mempool.
2- that transaction wont be picked for that specific block, the miner will go for the most rentable TX first.
3- the more UTXO the more expensive the transactions fees will be. so a growing mempool will be directly affected by the complexity of a TX and will be more expensive than simpler transaction where there is not split to several addresses and destinations.

The mempool is a list of unconfirmed transactions. Each node has its own mempool.
-
If miners can’t keep up with the rate of new transactions then the size of the mempool will grow.
-
Miners have an incentive to choose transactions which offer higher transaction fees, so this can have the effect of increasing transaction fees overall.

Homework on Mempool
Mempool is a list of all transactions that haven’t been confirmed yet.
If the miners cannot keep up there will be longer transaction times and a backlog will build up
Transaction fees go up,

Please could somebody answer some questions I have? A couple Are justKconfirmations.
can you confirm:
*if as well as high fees, a miner will prioritise a transactions with fewer inputs and outputs, because more of these take up more block space?
*That transactions are only returned to the mempool, if invalidated after the 6th block? One source told me that technically the previous five blocks are also part of the pool.
Also:
*Are miners fees only paid out, if and after accumulating up to when the 6th block confirmation takes place?
*do a high percentage of miners go out of business, if they spend so much electricity, and are unlucky enough, on so many occasions to not solve the algorithms attempted.
*Fees seem to be higher from a digital wallet, than when using an exchange. Is there a reason for this with respect to how miners interact with exchanges, rather than dealing directly with an SPV? I ask this because I have made transactions through exchanges and none have been delayed.
Thanks in advance
- The mempool is a place where unconfirmed transactions wait for a miner to pick them up to add to the next block.
- If the miners can’t keep up with the rate then the mempool grows larger and there are longer transaction times.
3.Transaction fees increase with a larger mempool because of the competition to get the transaction to the next block.

Following on from my last post, I guess that miners only interact with the mempool. If that’s the case, why aren’t exchanges much slower than SPVS, WhenThe latters fees are higher?
1. What is the mempool?
Menpool consists of all the unconfirmed transactions, but transactions that already make sense and are in the nodes but not in blocks yet, in other words, not in the blockchain yet.
2. What happens if the miners can’t keep up with the rate of the new transaction?
The mempool will get bigger.
3. How does a growing mempool effect transaction fees?
The fees will increase because there will be increased competition, since the transactions with the highest fees will be picked up by miners faster.

Sits in the mempool unconfirmed highest fees get confirmed first. Fees go up.

As more unconfirmed transactions sit in the mempool fees rise to the highest bidder to fit on the block. AS the mempool decreases lower fees will be accepted.

- A Mempool is where all the unconfirmed transactions are held and wait for a miner to confirm and add to the next block.
- The Mempool will get bigger and the confirmation process will take longer
- The Miners will always pick the transaction with the highest fees. A growing Mempool will push the fees higher as the more inputs and outputs there are the more space is required for any 1 block.

Mempool- Homework
1- Mempool is a data base that has every node in the chain where are stored all the UTXO´s untill a miner confirms them and put them in a block
2- The mempool then will grow and accumulate more transactions.Miners will pick the transaction with the highest fee to confirm it. The higher the fee , the fastest the transaction will be confirmed.
3- A growing mempool will result in an increase of the fees

Miners pick transactions based on the sat/B ratio, meaning they will pick the most profitable txs based on their size and fee. 
No, tx are invalidated if they get replaced by a tx with a larger fee and uses the same UTXOs, that gets in a block and gets confirmed thus invalidates the original tx.
In case of a stale block they get unconfirmed and returned to the mempool, but the blocks are part of the blockchain, they are not in the mempool.
That is relative, I have made very low fee transactions with a wallet. Exchanges on the other hand combine withdrawals into one large tx that makes it cheaper for them than sending each withdraw as a separate tx. This doesn’t really impact the price of the end user since exchanges usually have a fixed withdraw fee.
Same reason, they wait so they can cram as many withdraws from as many users into one tx to save on tx fees.

There be a need to pay higher fees. The highest fees will prioritize transactions to get to the blockchain faster
