Homework on UTXO vs Account Model

  1. It is a benefit because transactions can be processed more quickly. It also means more transactions can be stored on a block giving Ethereum blocks more scalability.

  2. The account model has one sender and one recipient, you can only send the exact amount. You can clearly see which address sent money, which address received it and exactly how much was sent. In the UTXO model a transaction has multiple outputs. You can’t clearly see which outputs are to a recipient and which outputs are being sent back to the sender. Nor can you see exactly how much was sent to another party.

  1. Faster transactions, more transactions, less computer calculations, less energy costs, and as a result more environment friendly.
  2. Bcz any one can see from which account funds came and to which account sent.

  1. It’s a benefit because the blockchain will be more light in terms of the data that it stores.
  2. Because we can follow all tx’s on the etherscan and can see who sends how much of something to whom. That kills privacy in some way.

Homework on UTXO vs Account Model - Questions

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    A: It will allow you to fit more transactions into each block. It will increase the processing efficiency of the transactions.
  2. How is the account model not as great as the UTXO model for privacy?
    A: It’s not as private as the UTXO model and the public will be able to see exactly what your balance is on the public ledger.

  1. The benefit of the account model not requiring as much space as the UTXO model is that more transactions can be stored on a block allowing them to be processed faster, reducing energy costs and increasing scalability.
  2. The account model is not as great as the UTXO model for privacy because every transaction can be traced from beginning to end, and see where it came from, where it went, and how much. Where as in the UTXO model it is harder to track because because transactions can be split to multiple outputs.

  1. Using an account model instead of the UTXO model results in less space which can free up resources on the blockchain to enable more transaction volume and the processing of smart contracts.
    2.The account model is not as great as the UTXO model for privacy because you can not batch multiple transfers back to yourself via wallet addresses that you control on the same transaction.

Homework on UTXO vs Account Model:

  1. When space within transactions is saved, it makes it easier for the network to process it, and express it in code/text.

  2. The account model provides less privacy since each transaction is singular. Unlike bitcoin, which allows multiple transactions to occur at one time. Making it difficult to infer who the addresses belong to. Therefore, ethereum makes it significantly easier to observe the transaction amount that was sent, and who it was sent to.

  1. Smaller txs. means more txs. per block => less fee / tx. and higher processing speed of txs. => more participants can be accommodated on the network.

  2. Account balances are updated => Exact amounts are sent => Not possible to split up a tx. between multiple targets (including the sender) => Harder to obfuscate tx. details as to what tx. amt. is going to whom exactly.

  1. It is a benefit as far as the scalability issue of the blockchain is concerned, as each block can contain much more transactions.

  2. When using the account model instead of UTXO model, you can’t send multiple transactions including transactions back to yourself.

    It’s a benefit because that means that more transactions can fit in one block.
  2. How is the account model not as great as the UTXO model for privacy?
    the account model is not as great for privacy because every transaction you make is transparent(the sender and the amount of money you sent to the reciever are both visible to everyone)

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    A block can store more transactions. Block space efficiency is always benefit because of the nodes have a copy of the entire blockchain.
  2. How is the account model not as great as the UTXO model for privacy?
    Bitcoin is a bit more Non Fungible so 1 ₿ is not 1 ₿ for example black shady adres.
    Ethereum is fungible 1 ETH = 1 ETH and in ethereum. Each transaction can be seen from the outside, how much was sent and to whom.

  1. Because the Account model does not register each Input and Output of each Transaction information like in the btc UTXOs model.
  2. It is more fungible, that means that there is no tracking of each UTXOs, if someone send you eth, you won´t see at a coin level wich individual coin represents which transaction, you can see the address that sent you money but ALL eths are the same.

    Benefits are uses less space, flexibility in terms of fungibility.

  2. How is the account model not as great as the UTXO model for privacy?
    Account model is fungible and UTXO model is NonFungible. Fungibility is less clarity.

    It takes less space and provides a balance at all times
  2. How is the account model not as great as the UTXO model for privacy?
    You can send yourself back in a multioutput transaction. Funds to from A to B it is easier to see

Homework on UTXO vs Account Model - Questions

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
  • Because it takes up less space it allows for the recording of more transactions.
  1. How is the account model not as great as the UTXO model for privacy?
  • The account model can only send to one address at a time. Making transactions more visible as you can see the address it went to and how much was sent. Unlike the UTXO model where you can obscure transactions by bundling multiples addresses in one transaction, making it harder to track where transactions where sent to and how much was sent to each address.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Because the transactions are smaller, so the blocks are lighter, and hence makes Ethereum faster.

  2. How is the account model not as great as the UTXO model for privacy?
    Because the information is more visible, since it’s moving the balance from one address to another.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?

A: It’s a benefit because it uses less space, which means you can fit more tx’s in each block, at a cheaper price. It also doesn’t require the nodes to hold a copy of the entire UTXO history.

  1. How is the account model not as great as the UTXO model for privacy?

A: Because the account code & balances are public. With the UTXO model, you are able to send money to a recipient and yourself within the same tx. With the account model this is not possible as you are moving coins & essentially subtracting it from one balance and adding it to the other. There are no ‘input’ or ‘output’ notions.

  1. it is not only easier to write in code but also saves space in blocks.

  2. in a UTXO model you would send btc to multipole addresses in one transaction, but in an account model you send the exact amount to one address, so it visible how much and to what address you send to.

    There will be more space on each block for more transactions. The nodes do not need a full transaction history also saves space.
  2. How is the account model not as great as the UTXO model for privacy?
    On ETH the transactions are more public and more people can see it. With BTC there will addresses but keep a sense of security.
