Homework on UTXO vs Account Model

  1. It is beneficial because it uses less space. There is no notion of UTXO’s, just stores balances.

  2. The account model is less private. You can track who has paid and if the money goes to you but the UTXO model you can send and receive but you cannot see who the transactions are going to whether yourself or someone else.

Less space is put onto the Ethereum Blockchain, meaning more efficient transactions and fewer costs to put it in the blockchain.

It is not as great because, unlike the UTXO model, you’re able to see exactly how much one account is sent to another. With the UTXO model, UTXOs are sent to both the recipient and the original account, so someone looking in from the outside won’t know how many funds were sent to each individual.

The account model does not have utxo which lowers data requirement thus reducing the size and making it faster

The account model is not good for privacy as you can track the address each transaction can be seen, how much was sent to whom

  1. It is a benefit as it reduces the block size thus rise the speed and the number of transactions to be validated.
  2. Because in the UTXO model, you can send back money to yourself or splitting your transactions into different UTXOs but in the account model, the balance simply adjust once the transactions have been made.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Less space means more transactions fit in a block, making it faster and cheaper.

  2. How is the account model not as great as the UTXO model for privacy?
    The account model registers the balance, making it easy to read where a transaction comes from and where it goes. It is harder to trace all UTXO’s as they can have multiple outputs in one transaction.

  1. Faster transactions, cheaper transactions.
  2. Because you can do multiple transactions to your self and others, and the one who watches cant tell witch is going were.

  2. Because you cannot backtrack the transactions.

  1. the saved space can be used to store code, state, and transactions in Ethereum

  2. using UTXO model, we can send money both to real recipients and our wallets in one single transaction, which makes tracking the money flow harder

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?

The benefit of smaller transaction size is that it increases the speed and efficiency of all nodes on the network by consuming less resources.

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

The benefit in terms of privacy of the UTXO model when compared to the account model is that you can make several outputs at the same time having funds going to a third party and another address you control at the same time, therefore creating confusion.

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

the benefit of not requiring much space is the faster transaction speed
The UTXO model limits the amount of code we can fit in a block. Ethereum allows more transactions to fit per block.

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

because the account model allows us to see who trancted to whom and see exactly how much was spent in a transaction.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
  • Because it will take less space and therefore it will make transactions faster.
  1. How is the account model not as great as the UTXO model for privacy?
  • due to its simplicity the security part is a bit reduced.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? – Saving space is always more efficient since more data can be fit into the block, moreover, there is not a data center holding or managing data (as happens in centralized finance), therefore the network is operating by individuals thus the less the data the more individuals can join the network (somehow make it easier for individuals to join).
  2. How is the account model not as great as the UTXO model for privacy? – UTXO model eases/offers privacy advantages to users. Users can handle each UTXO separately by storing each UTXO in a unique address, privacy is possible while account model is traceable.

  1. With less space you can store more information and transfer information faster.
  2. Account model is less private because you see where the transaction goes but with UTXO model you can send to several outputs not showing to whom you send funds.

1- Because the account model doesn’t require more space like the UTXO. It reduces block size and make the Tx faster.

2- Because you can track the sender and receivers transactions.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It is more fungible and less traceable. Therefore it is easy to swap and change from one coin to another. Since there is less space it makes things run faster overall than you would have on a model more like BTC.

  2. How is the account model not as great as the UTXO model for privacy?
    You can see exactly which address/accounts sent transactions each way for both sending and receiving.

#3907

1.) The account model not requiring as much space as the UTXO model is a benefit because transactions are easier to explain in coding and smart contracts. With UTXO’s, one transaction can have many outputs and can make coding more difficult to develop.
2.) The account model isn’t as great as the UTXO model for privacy because it is a lot easier to track an original input. The UTXO model uses a lot more block space, and UTXO’s can be spread all over an initial transaction; in contrast, an account model transaction can be simply traced to the address where two accounts traded balance numbers.

1.account model requires less space than UTXO model and makes for more transactions and faster payments
2.account model has less privacy because you can see the exact addresses sent and received and single transactions cant be split up to multi addresses as is the case with the UTXO model.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    The Account model does not save each utxo as it stores balance of all transactions reducing the space each takes up in the block, it also has hundreds of ERC20 tokens settling on the ETH blockchain.
  2. How is the account model not as great as the UTXO model for privacy?
    UTXO can be spent to multiple accounts making it harder to track and know which address is the same as the senders and it is possible to track each btc. In the account model is much simpler, it goes from a to b. in the account model it is possible to see the balance-all eth are the same.

  1. It’s simpler and it takes up lesser space on the blockchain.
  2. Because on BTC, when you view the UTXO’s you cannot / don’t have a way to distinguish which wallet receives transactions. On the other hand, Ethereum shows all transactions information including address, and you can only send transaction to one address and not multiple.

  1. The nodes will need less storage space and also can fit more transactions into a block
  2. You can see where the money is coming from and where it is going in a single transaction whereas in the UTXO model there are multiple inputs and outputs where the outputs could actually be going back to the original owner and someone reading the transactions wouldn’t know
