Homework on UTXO vs Account Model

  1. Quicker transactions, blocks can store more transactions.

  2. Because with UTXO you cannot see where the people are sending money to, it could be to themselves or someone else.

  1. Having more space on a block would be a benefit as it will avoid issues with slower transaction confirmations and fees.
  2. The account model tracks the exact addresses of where it was sent from to where it was sent to with absolute certainty. While with utxo, one can potentially send to multiple addresses in a single transaction including to oneself.

Homework on UTXO vs Account Model - Questions

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    In Ethereum there is no notion of UTXO´s, the account model requires less space in the block than the UTXO model. The blockchain can add more transactions per block, resulting in more transactions per second.

  • How is the account model not as great as the UTXO model for privacy?
    At the Ethereum blockchain we can see exactly what amount was sent and to which address. It’s a little less private than BTC, because on the Bitcoin blockchain we can send funds to someone and to ourselves at the same time making it harder to know which one is who.

  1. Transactions taking up less space in the account model is a benefit as this means more transactions can be added to each block.

  2. The account model doesn’t allow users to send money to multiple wallets within the same transaction. This means you cannot obfuscate your spending by sending money back to yourself in addition to other recipients like you can with the UTXO model.

  1. This means you can fit more transactions in one block without slowing down the time it takes to propagate the new block throughout the system.

  2. With UTXO, you send a whole amount, sending the amount you want to the recipient and the change back to yourself and there is no way for anyone to know which amount was sent to the recipient and which amount was sent back to yourself - all they can see are two UTXOs. With the account model, however, you send a specific amount so everyone can see how much was sent and how much was received.

The account model doesn’t require much space as the UTXO model, why is that a benefit?
Because there are no inputs and outputs, only we move funds from A to B and then update the numbers at the blockchain, so there is no UTXO.

How is the account model not as great as the UTXO model for privacy?
In Bitcoins there are inputs and outputs, no coins, only UTXO, so we can easily track inputs and the outputs, so we can follow them, how did they traveled through the network, so in bitcoin we can know exactly where the UTXO came from, while in Ethereum we don’t have the same tracking, because we have the updates of balances, so we can not go back and see exactly where it is coming from so we don’t have the same traceability of coins, which makes the coins much fungible.

    Less storage capacity is required.

  2. How is the account model not as great as the UTXO model for privacy?
    Because the account model does store a balance and it is easier to see the amount and participants in the transaction.

The account model doesn’t require much space as the UTXO model, why is that a benefit? That is a benefit because you there can be more transactions recorded into the blockchain, unlike Bitcoin that is more constrained.

How is the account model not as great as the UTXO model for privacy? The UTXO model involves sending outputs that are spread across multiple addresses, some of which may be to other addresses owned by you; whereas the account model involves transferring balances from one account to another, which is more traceable.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    The account model is simple and efficient because it only updates the balance.

  • How is the account model not as great as the UTXO model for privacy?
    The account model keeps a record of the sender and receiver of the funds only. The UTXO model keeps track of single bitcoin transactions which can go out to many outputs at the same time.

Homework on UTXO vs Account Model - Questions

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

Answer: less space, means faster transaction beacause more can be processed in the same space.

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

Answer: Because there is more information reconciled in a smart contract and the utxo’s must be reconciled to connect the dots for the same understanding of information.

hello,
1) A benefit of account model over UTXO is account model has less data per transaction allowing for more transactions per block.
2) Account model is not as great as the UTXO model for privacy due to the fact that there are no change wallets in ethereum allowing someone viewing the blockchain to see how much money was sent and to which addresses it was sent to.

1.Account model does not save each utxo as it stores balance of all transactions there reducing size of block making it faster

2.Easily to know where the money come from and where you send money to. UTXO model is hard for public to tell which amount of money goes to where, because one transaction could have multiple outputs.

  1. Less block space makes faster processing transaction and lower transaction fee.
  2. Account model is easier to track where is the transaction comes from and the amount send to whom.

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

It is a benefit that the account model doesn’t require much space as the UTXO model because it is simpler, allowing for faster transaction and processing time. Transactions on the ETH blockchain are updated leaving a current balance only. It is also said to be more fungible because the coins cannot be tracked nor distinguishable between other coins on the blockchain.

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

The account model is not as great as the UTXO model for privacy because it is apparent how much ETH you send and to which address. Whereas with BTC and the UTXO model, you have some privacy, because in a single transaction you can send BTC to someone else and back to yourself without making yourself obvious to an outsider.

1 The account model doesn’t require much space as the UTXO model, why is that a benefit?
it means the construction of Txs are less complex than with BTC allowing for:

  • more TX per block
  • faster processing
  • lower fees (though you may not believe that right now…)

2 How is the account model not as great as the UTXO model for privacy?
ETH accounts may be considered as similar to your holdings with a bank; anyone who has access can see all your holdings and because its a public blockchain this means everyone can see the holdings in any account. Contrast this with BTC where wallets/accounts dont hold a balance but link to a series of UTXOs which then give you your balance; with UTXOs there is no way for anyone to determine which output in a UTXO belongs to which recipient

  1. It’s a benefit because you can fit more transactions per byte.
  2. When using the UTXO model you spend all your UTXOs into different outputs (recipient addresses) when sending BTC. You may be the owner of all recipient addresses, the outside world doesn’t know which addresses belong to you. This makes it somewhat private.

  1. It makes transactions easier to track and monitor. As well as making ETH more fungible.

  2. Because no funds are sent back to yourself. Its only the account sent from and sent to that is listed so in this way it is less anonymous and less secure.

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

Answer: Using less space creates less congestion on the blockchain and saves time which is more efficient.

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

Answer: With the account model the transactions are more easily identified than the UTXO model because transactions can’t be split and sent to more than one address.

  1. The account model is not as great as the UTXO model for privacy because you can track each UTXO to know where each coin comes from. There are no traces of the account model coin because there are no input or outputs.

1.More space for an account model means that the transactions fees are smaller.
2. The UTXO model does not have private account balances so, every transaction is traceable.
