  1. increases transaction speed.
  2. the acct. model is based on updates vs. utxo’s which follows the outputs and returns to original sender acct.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? I would think that any space savings is a benefit when you are talking about scalability and speed of the network, space saving would facilitate growth in these areas.

  2. How is the account model not as great as the UTXO model for privacy? Because you can see what wallet is responsible for each tx.

  1. The account model requires less space than the UTXO model. That benefits the network with faster transactions, not as much storage on the block and greater fungibility.

  2. On the account model you are sure how many coins the recipient received, while on the UTXO model it can be doubtful if the coins were sent to a recipient or came back to you.

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?

Having more space on each block is a benefit because it allows for blocks to include more transactions, and that is essential for the Ethereum ecosystem since there are thousands of tokens being settled on the blockchain.

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

Because there are no “change” wallets in Ethereum, you can´t send funds to yourself, funds go from one wallet to the other, and that makes it easier to follow visually. On the other hand, Bitcoin with its UTXO model, is more complex in the transaction progress, all the unspent transactions go to a “change” wallet, making it more difficult for someone to identify which of the addresses are other users or the owners “change” wallet.

  1. Less space, so more transactions can be fit in
  2. The transactions are easier to be tracked on the account type, and it’s more fungible too

  1. less space that is mean more transaction can be stored in one block.
  2. we can easily know how many was sent , where it sent to and where is it from.

  1. This is a benefit because the less space used in the block the better, so using less space is considered beneficial.

  2. The account model lacks in privacy compared to the UTXO model because it is much easier to track where the transaction came from.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It is more simpler, one block can store more transactions and faster processing.

  2. How is the account model not as great as the UTXO model for privacy?
    In UTXO model, there is tracking system, we have input and output, each previous output is input, we can track UTXO.
    In account model there’s no input or output, we can see all TX and who send TX, we can see balance update, which is number. We can’t distinguish between coins, we have TX and who send money, we can’t see what coin is from what TX.

Hi everyone,

  1. More transactions can be included in a block, they can be processed faster, which is a benefit for scalability.
  2. With the UTXO model, a transaction can have multiple inputs and outputs. You can for example send money to various adresses, some of them being yours, so really we can not easily work out that A is just paying B, it’s kind of hidden by the multiplicity of inputs and outputs. The account model is more simple, some money is removed from an account and added to another account, it makes it easier to just see A is paying B, which is not as good for privacy.

  1. Benefits of the smaller account model are as follows: with transactions being smaller than they are in the UTXO model, the node file of the Ethereum network increases in size at a slower rate. Also, transaction fees in the account model are less than they could be in the UTXO model, otherwise.

  2. If privacy is the priority, the UTXO model is a better choice for the following reasons: The code for the Ethereum account is public along with the balance in those accounts. An individual is able to camouflage his financial transfers with the UTXO model (as in BTC), and no so in the account model such as that used in Ethereum.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It is a simpler model and doesn’t take nearly as much space on the block chain.
  • How is the account model not as great as the UTXO model for privacy?
    You cannot in essence hide transactions in the same way you can with BTC. In BTC, you can send some or all of a transaction back to yourself and on the blockchain it will be impossible to see when this happens and which receiving wallet is one that you control.

  1. More transactions can be processed , and the can be processed faster compared to bitcoin because the miner does not have to scan the blockchain for every single UTXO.
  2. with dthe account model you do not have the ability to send yourself funds back. In bitcoin you can send someone an amount of BTC and send the rest back to you. In the accounting model of ethereum you can only send ETH to a different account, but to yourself.

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

More tx’s can be processed, so the network is faster. It’s more scalable. One block can store more tx’s.

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

On the Eth network you can easily know how many eth was sent, from where and to where, while on the UTXO model you can doubt if the coins were sent to a receiver or to themself.

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

It can increase quantity of transactions in one block and speed of the network.

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

You can directly define transaction values and directions. From whom and how much ETH was sent. The UTXO isn’t perfect as well in that but has more complex traceability comparing with accounts.

  1. Account models can process more txns per block = cost effectiveness.

  2. The account model is more highly transparent since you cannot send to yourself in multiple utxo txns which obfuscate how much and to who.

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 account model of the Ethereum network does not require as much space as the UTXO model because it is much simpler and does not require it to track the UTXO and the input/output of its transaction.
  1. How is the account model not as great as the UTXO model for privacy?
  • The account model is as not as good a privacy model as the UTXO because it has a more straightforward transaction model and accounts can be tracked easier. In the UTXO model, there is no way from the outside to track if a UTXO account goes to a different account or its own account.

  1. With less space requirement more transactions can take place at a faster pace.
  2. With the account model has wallet reuse and uses a name service that can tie wallets to other wallets and a person’s public identifier. A UTXO is fungible and less easy to track.

  1. First your assets are not traceable on Ethereum because balances are just changed you cant see which particular coin came from where in its origin. You have more space for more Transactions in a block and you are more scalable

  2. Because you can see from which account the money came from and caust the balance change. In Bitcoin you just the outputs and you have no balance to take a look. On Ethereum you also cant send Transactions to your own same wallet.

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 the less space usage allows more transactions in a period.
In other words, the account model allows to shortcut the time that nodes read every single UTXO. This allows more transactions!
The account model allows you to verify the flow of ETH but not the details. For example, which ETH coin is used for the transaction, etc.

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

The drawback of account model is you cannot send ETH back to the same address.
On the other hand, you can send some BTC to both multiple addresses including your address in one transaction.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It is a benefit because less space is required and that allows to add more transactions into a block.

  2. How is the account model not as great as the UTXO model for privacy?
    Because the account model makes it much easier to know exact transactions and where Ethereum is flowing on the blockchain so it is fungible, while UTXO’s only track unspent transactions and the BTC wallet SPV will track those UTXO’s and adds them all together from the blockchain.
