Homework on Mempool - Questions

  1. What is the mempool?
    The mempool is a collection of recorded transactions examined by nodes, but as yet unverified by miners.
    They’re like planes on the taxiway waiting for clearance to take off.
  2. What happens if the miners can’t keep up with the rate of the new transaction?
    If there’s a backlog of miner verifications, a backlog would form, and transaction times would increase. This would probably increase transaction fees, which would attract more miners :slight_smile:
  3. How does a growing mempool effect transaction fees?
    A larger mempool would tend to increase transaction fees, as higher fees would be offered or demanded in order to attract miners to transactions.

1- A transit stop for all newly received transactions on the way to their final destination where they get confirmed.

2- Memo pool size becomes larger.
(Although, I am not sure why would fees increase when a sender already agree upon a specific % of fee at the time of processing the transaction?

3- Fees of new received txs increase.

Mempool is a list of transactions that are valid and waiting to be added to the blockchain.

When a transaction is send to a node and the node has validated it and broadcasted it forward to other nodes it is also been added to a list of all other valid transactions that have reached and been checked by the node.

Transaction confirmation time will increase if the miners can’t keep up with the rate of new transactions.

The mempool will keep growing and transaction confirmation time will increase.

Growing mempool will increase the transaction fees.

As it takes longer time for your transaction to be confirmed the result for reasonable fast transaction at this point would be increasing the transaction fee.

Increasing the transaction fee will make your transaction more attractive for miners to look at since miners get the fees and are therefore incentivized in patching up a block with transactions that are small by size and that has the highest fees.

  • What is the mempool?
    Transactions are inside the mempool waiting to get picked by a miner which wraps it in the next block.
  • What happens if the miners can’t keep up with the rate of the new transaction?
    Transactiontimes growing cause the miners can‘t handle the amount of transactions.
  • How does a growing mempool effect transaction fees?
    Transactionfees are higher.

  1. A list of transactions.
  2. The mempool develops a backlog which slows transaction speed.
  3. Transaction fees increase in order to incentivize miners to process Transactions.

  1. What is the mempool?
    A mempool is a list/data structure of verified (double spent) unconfirmed transactions.

  2. What happens if the miners can’t keep up with the rate of the new transaction?
    List of unconfirmed txs is then larger - lots of txs have status pending

  3. How does a growing mempool effect transaction fees?
    Increasing of fees because of bigger competition in txs. Miner would like to pick txs with the highest
    fees - satoshi/byte. Every block size has a space limit.

1- Mempool is the list of all unconfirmed transactions held by a node, waiing for a miner to add them to a block which will confirm/ complete the transaction.

2- Transactions will take a long time to be added to the blockchain and confirmed

3- Fees will rise as miners seek to process the highest fee paying transactions first, wallets will see this and propose you pay a higher fee than the latest transactions and this can snowball while the network is busy.

  1. What is the mempool?
    unconfirmed transactions that are wating to be confirmed

  2. What happens if the miners can’t keep up with the rate of the new transaction?
    A backlog of transactions builds up --> Growing the mempool

  3. How does a growing mempool effect transaction fees?
    Transaction fees will go up as he mempool builds as there is more competition for priority processing and the fees to do such transactions will go up due to supply and demand of processing speed of the miner network

  1. A mempool is a list of unconfirmed transactions that each node holds. Each node may hold a varying amount of transactions in it’s mempool (just means certain transactions have yet to be broadcasted to it.)

  2. If the miners can’t keep up with the rate of the new transactions, then the mempool will continue to grow and get larger.

  3. If a mempool continues to grow, then users sending transactions will have to spend higher Tx fees if they want their transaction to go through.

1- The mempool is the list of all verified but unconfirmed transactions waiting to be entered into the blockchain.
2- In the case miners are unable to keep up with transactions the transaction time increases.
3- The increasing mempool has for effect of increasing tx fees due to the fact that miners choose the tx’s with the higher fees thus creating a competition among tx’s with higher fees having a snowball effect.

  1. What is the mempool?
    mempool represents the transactions that have been broadcast to the network but are yet to be confirmed by a miner and added to the blockchain

  2. What happens if the miners can’t keep up with the rate of the new transaction?
    The mempool will get larger, having more unconfirmed transactions in it.

  3. How does a growing mempool effect transaction fees?
    Transaction fees will increase as people would want to pay more to have their transaction included in the blockchain faster

1.- Mempool is where txns are store before they are picked and added to a new block by a miner.
2.- If miners cant keep up with the rate of new txns, mempool starts to grow in size.
3.- A growing mempools induce new txns to increase proposed txn fees in order to get picked quicker by a miner.

  1. The mempool is where all transactions are kept after being validated by nodes and before being confirmed and added to a block on the blockchain.

  2. If miners can’t keep up, the mempool grows and transactions will take longer to be executed.

  3. If there are many transactions in the mempool waiting to be confirmed, it means there will be longer processing time for a transaction. Transactions with higher fees will be executed first by miners, therefore fees will increase.

What is the mempool?

a mempool is where all unconfirmed transactions go that has not yet entered the blockchain, a miner still needs to pick up the transaction

What happens if the miners can’t keep up with the rate of the new transaction?

The transactions will build-up

How does a growing mempool affect transaction fees?

They make them more expensive, miners take the transactions with the highest fees first

  1. Mempool is a pool of unconfirmed transactions. Every node has its own mempool. This contains its own transactions that are not confirmed yet and also unconfirmed transactions of other nodes that are waiting for transactions.

  2. If there are many tx that have to be confirmed, the mempools will grow and it will take longer for a single tx to be fulfilled.

  3. Every tx has to be confirmed by miners. Only then, the transaction is made and put on the blockchain. The incentive of miners is to make money. Every tx has a fee which is “paid” to the miner. Hence, the miners first accept those transactions that have the higher fees.
    If the mempools are growing the fee rates will rise because one is willing to pay more fees for a faster fulfillment of the tx.
