Homework on UTXO vs Account Model

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Because you can put many more transactions on each block as they are much smaller.
  2. How is the account model not as great as the UTXO model for privacy?
    Its less private as its easy to see the address the transaction comes from and to which account it goes to whereas UTXO is more private as you can have multiple outputs which you can’t identify.

  1. The benefit is that you can have more transactions in one block which naturally will decrease the fee for each transaction.

  2. The account model not as great as the UTXO model for privacy since you cannot split your transaction therefor you can see exactly who received it and see exactly how much.

  1. Less Tx byte size allows for more throughput on the network.

  2. With the account model in ETH, you can see each Tx, in that it shows which account sent what amount to which account. In the UTXO model of BTC a wallet can construct a Tx to send part back to yourself or chop up outputs into different amounts so that it is next to impossible to find out.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Allows for smaller transaction data relative to UTXO model, aka more transactions per storage space.

  2. How is the account model not as great as the UTXO model for privacy?
    Much easier to track transactions between accounts, and the coins are Fungible in ETH. In UTXO model, transactions are more complex and cannot be tracked based on amount sent to an account/wallet as the tx’s can be broken into multiple routes and values.

1 - By using the account model it frees up more space on the blockchain allowing faster transactions.
2 - The account model allows anyone to follow the transactions on the blockchain clearly however with the UTXO model it isn’t as clear.

  1. It will be quicker for propagating it through the network, less tx times.
  2. You can always see from where a tx comes from, there is no change back in 1 tx as with btc.

  1. In distributed system it’s benefit to transmit smaller (aggregated) data because data size has dependence on system performance and scaling.
  2. In UTXO model better hide which part of transactions is send as payment and which is “send” back to you.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It makes the transactions faster and make room for more transactions.

  2. How is the account model not as great as the UTXO model for privacy?
    Account model it is easy to see where the tx came from and where it`s going. UTXO can be sent to different addresses at the same time and while you can see trace the final amounts in the tx, you can not see what assets where used in the tx.

1. The account model doesn’t require as much space as the UTXO model, why is that a benefit?
Transactions don’t take up as much space as in the UTXO model meaning more transactions can fit in a single blocks, so it’s faster and more efficient.

2. How is the account model not as great as the UTXO model for privacy?
With the UTXO model there is no balance and you can send funds to different outputs (including yourself) in one single transaction making the UTXO model more opaque. The account model does have a balance and is very transparent because there are only 2 addresses involved in a single transaction. If someone knows your address it is not difficult for them to see you’re balance and to trace back what amounts you’ve received and send from/to whom (what address). This can all be seen on the blockchain and there’s no way to “repackage” transactions with some additional outputs like in the UTXO model.

  1. The account model doesn’t require as much space as the UTXO model, this benefits the account model in the sense that it helps to keep block sizes smaller, more transactions into a block and is faster.

  2. The account model is not as great as the UTXO model in the sense that in the account model when a transaction is made it simply changes the account sender and account receivers account balance instead of doing it in the UTXO way where all coins are simultaneously sent, the receivers amount then the remaining back to the sender.

1/. Less space is better because it speeds up transactions and allows for more transactions to complete quicker because they are smaller.

2/. The account model is not as great as the utxo model for privacy because it is easier to see where the money has come from and where its going to, whereas the utxo model has multiple inputs and outputs.

  1. Is a benefit for number of transactions that a block can hold, and for the overall size of the blockchain in storage.
  2. In the account model the transaction goes directly from wallet to wallet, which contains the actual balance, for the UTXO model instead the inputs and outputs charasteristic makes it less clear how much money goes to whom.

  1. More room for smart contracts :slight_smile:
  2. With the UTXO model, distinguishing between the two outputs of a simple transaction is impossible.

  1. The account model does not store the balance of the transactions making the block size smaller.
  2. Anyone can see the transaction inputs and outputs in the Ethereum account model whereas the UTXO model doesn’t allow visibility into where the output transactions are going.

  1. It could be because transaction can be faster due to less information. UTXO’s can track back to the origin transaction whereas the Account Model simply adds or subtract.

  2. From the outside the account model blockchain will show how much eth was sent from an address and to whom received it plus the outsider will know that it was definitely received.

  1. Less space means you can fit more txs and/or smart contract bytecode on a blockchain of a given size.
  2. In the account model when you send funds it is clear who is receiving them (the other account), whereas with the UTXO model some funds may get returned back to your change address, but outsiders cannot distinguish between the recipient’s address and your own change address.

  1. a)Simplicity for programmers.
    b) Storage - more room for contracts .
    c) Smaller fees ? …
    d) Faster network .
  2. In UTXO model user can use new address for each transaction that they receive then it can be difficult to link accounts to each other. Also you can use multiple outputs .

  1. This allows for more transactions per block, which might make transactions cheaper and faster.
  2. The UTXO model allows for multiple outputs per transaction whereas the account model allows only one.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Account model benefits would be that it is much simpler and more efficient than UTXO.

  2. How is the account model not as great as the UTXO model for privacy?
    UTXO transactions are deemed to be more private as you cannot easily know the recipient of the transaction especially as a UTXO transaction will have at least 2 UTXOs. With account model you will be sending to a single address where the receiver may be known.

  1. It’s more simple and efficient since the transactions don’t have to include state information.

  2. In UTXO model’s stateless environment, users are encouraged to use more addresses for every transaction instead of an account.
