    smaller and faster
  2. How is the account model not as great as the UTXO model for privacy?
    with utxo you can send change to yourself. you cannot with accounts in ethereum. You can also see account balances instead of having to search for all utxos for a specific address

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    When you have more space you can add more transactions to blocks.
  2. How is the account model not as great as the UTXO model for privacy?
    you can’t go back and see where you got money from

  1. The blocks will be able to store more transactions, increasing the efficiency of the node.
  2. Because in Account Model, you can’t send your own money to yourself in the same transaction, which helps cover tracks if you want that feature.

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. The account model saves space by not needing a UTXO and only storing the actual transaction making it more scaleable.
  2. How is the account model not as great as the UTXO model for privacy?
    A. In the Account Model you can see how much was sent and to who.

  1. quicker transactions because the tx data in blocks is smaller
  2. cannot send to oneself to hide identity or ownership, also one balance = one public address (by checking an address, one can easily see the complete balance of the address), not like in bitcoin where a single wallet uses multiple different addresses known only to the private key owner

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

Hello sir, could you explain a little bit more why you said that? you mean the UTXO model or account? I do not understand the answer to this question.

If you have any more questions, please let us know so we can help you! :slight_smile:

It is a benefit because you can get more transactions in each block.

Its more transparent since its more of a simple ledger.

  1. The account model needs less space for a transaction (less complex because of no UTXos are stored)
  2. The transaction shows the amount of coins beeing sent. e.g. 2 ETH from Address A to Address B.
    Each account model transaction update both sender and receiver account which means less privacy.
    On the other hand BTC transaction is more trackable on Coin-Level but due the fact that a tx can consist of several UTXOs it is not clearly visible which UTXO address is owned by the sender of the transaction.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    There is less information in each transaction enabling more transactions to fit in each block.

  • How is the account model not as great as the UTXO model for privacy?
    It does not allow you to obfuscate the value holder’s identity by sending the UTXO on to a new account.

1 that is a benefit because that makes for less data per transaction. therefor you can fit more data into a single block. Increasing speed of transaction and more functionality.
2 Because you can track where your ether is coming from. Ans where it is going. You can not send it to the same adres in a single transaction.

  1. Because in that account model it shows your balance, it stores transactions and it doesn’t have UTXOs, so it updates them in your account. As well as the blocks can include more transactions, because it doesn’t need update the inputs and outputs.

  2. Because there are no inputs or outputs, the transactions just move from point a to b. It just adds and removes the numbers from your balance. The other nodes can see to which person you have sended or received the transaction from.

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

It is beneficial to take up less space because it allows more smart contracts and transactions to be appended onto the block chain. As an added benefit in allowing more transactions to be added to the block chain, miners may charge lower fees.

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

In the account model you can send exact amounts in a transaction, eliminating the need to make change as in the UTXO model. In the UTXO model you can send money to yourself, to make change, as part of a multi part transaction that you cannot distinguish to whom each transaction goes to. In the account model you can send money to another account controlled by you, but that transaction would also be from one account to another account, or one on one.

  1. Less space spent on transactions means more space for other functions on the network.

  2. The account model does not allow for the addresses in which the money is being sent to be convoluted making it easier to track. UTXO allow for many output destinations in one transaction so it is more difficult to tell who is receiving the funds.

This increments the speed of the network, as the transaction history does not have to be traced back in order to generate a balance.

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

With the UTXO model, several outputs can be generated at the same time, and it is not possible to tell which output went to what recipient. With the account model it is visible on the blockchain which adress sent, and which received the given amount.

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

The account model has three strong benefits

  • Space- each new block can include more transactions
  • Speed- with less data generated at each transaction the transaction speed increases
  • Money laundering- stolen coins are easier to use on an account model because they cannot be traced.
  1. How is the account model not as great as the UTXO model for privacy?
  • The account model only processes individual transactions. Therefore, the sender and receiver of each transaction are clearly visible.

  1. more transactions and faster transactions.
  2. account model tracks the address of who you paid, with utxo model you can pay a new address which could be your own.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Smaller contract/transaction size on the Blockchain makes for faster transaction times because more contracts can exist on each block.

  • How is the account model not as great as the UTXO model for privacy?
    It is easier to trace exactly the source and destination of a contract on the Ethereum Blockchain compared with a transaction on the BTC blockchain which has multiple inputs and outputs. This makes for increased privacy.

  1. The account model has a benefit over the UTXO model because less data is required which can speed up transaction times and fit more transactions on each block.
  2. The UTXO model is more private than the account model as it is easier to trace transactions on the ethereum network compared to the bitcoin network.

1. In Ethereum you do not have transactions with the same information as in Bitcoin, just updates of balance in the accounts. This enables a larger number of transactions
2. In the UTXO model one input can have several outputs. This makes it harder to find out to where it goes. In the account model one input will have one output thus easier traceable.

1 Transactions can be made faster because the code is lighter.

  1. Transactions happen between accounts A and B and are easily traceable. With UTXOs it is possible to include yourself as a recipient and obscure which amount goes where.
