Homework on UTXO vs Account Model

Ethereum 101
#81
  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? This is a benefit because each transaction takes up less space on the blockchain allowing for faster transaction speed and lower fees.
  2. How is the account model not as great as the UTXO model for privacy? The account model is less private because it is not possible to send transactions back to yourself. This means the exact transaction amounts between addresses are always visible.

This means a block can take more transactions. Also, it is faster to get the total balance if an account.

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

In Ethereum a transaction takes one input and one output, while in Bitcoin each transaction can take multtiple inputs and outputs (UTXOs).

  1. Benefits are: less storage burdens, bulk transactions are more efficient, accounts are stateful gives over all account balance, gives developers abstraction thats easier to understand and interact with and build app’s for.
  2. UTXO is stateless environment, users are encouraged to use new address for every transaction improving privacy.

    It allows the network to operate faster and cheaper as it is more efficient, blocks can have more transactions.
  2. How is the account model not as great as the UTXO model for privacy?
    With a UTXO model you can send part of a transaction to one person and the rest back to yourself in a different wallet for example and it is harder to track how much btc you may have.

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

The account model effectively incentivizes reuse. As the cost to the system (possibly in fees, but certainly in node operation costs) for a balance update is lower than the creation of a new balance.

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

The account model inherently incentives revelation of transaction sources.

The UTXO model improves privacy by making it more difficult to associate transactions issued by the same party.

    Because therefore more transactions fit into the same block size.

    In contrast to the account model, with the UTXO model you can create several outputs in a transaction and with that mask who the beneficiary and the amount paid is.

  1. Can include more transactions per block for same block size. Smaller fees since fees are per byte.
  2. Accounts are public. Not sure if account holders’ names show up or something like that.

  1. The Ethereum TXs take less space which is less complex than the UTXO model of BTC but it is a bit less private.
  2. Anyone viewing the Ethereum blockchain can see how much money was sent and to which address it was sent. In the UTXO model, some UTXOs can be transferred back to the sender so it is more difficult to determine how much was really sent to the recipient, making the BTC TX more private.

Hello,

  1. The code is expressed more easily with the account model, and the transactions are lighter data-wise because it just requires updating the shared database of the nodes.

  2. With Ethereum you can trace how eth has travelled from one account to the other directly, but with the UTXO I can send back btc to myself and to some other guy with the same transaction, so it becomes more difficult to understand how much btc has been effectively sent to some other user.

Best,

  1. because it keeps the TX low in file size, you can have more transactions in a block.
  2. you can not send part of a transaction back to yourself or divide the transaction in more smaller transactions. at the end it is a balance that takes one away from you and adds it to the person you send it to. You can see exactly the amount and the destination.

  1. It means more transactions can fit into a block and allows for easier mining.

  2. with the account model you can’t create ambiguous transactions hiding how you spend your money due to transactions just being an update from one account to another as apposed to having multiple outputs of a transaction that could be going to anyone including you.

1 That makes scalability more efficient because it takes less memory to send a transaction. As a result we get cheaper and faster transactions than a blockchain that have UTXO model such as bitcoin.
2 On one ethereum transaction you can only send your coin to one recipient. On a UTXO model on the same transaction you can send your coin to one other recipient and to yourself at the same time which makes it harder to track it.

  1. The account model doesn’t require much space as the UTXO model is a benefit because it means the Ethereum blockchain will not fill up as fast as the Bitcoin blockchain and so more transactions can be included in each block which helps with scalability.

  2. The account model is not as great as the UTXO model for privacy because the account balances are shown and you can see exactly how much money is transferred from one account to the other. The UTXO model on the other hand can send outputs to multiple addresses including yourself. An outsider does not know who owns those addresses so it is easier to be more private.

  1. More transactions can occur on each block which speeds up transaction time.

  2. Funds simply move from one account to another making it easy to see where funds came from and where they went to. Bitcoin, on the other hand, allows for funds to go to 2 places within the same transaction making it a bit more private.

  It benefits because it makes it much simpler.   It is much easier to say, "Send 1 coin from A to B."  than to say, "Send this many coins through 5 inputs and through these 5 outputs."  I hope that made sense.
  The account model makes it so that you can't send money back to yourself and give yourself change.

  1. Because it requires less storage and less code to be written. In this way, each block can include more transactions.

  2. In UTXO model it’s easier to hide your activity as you in the same transaction you can send money to different wallets and even yourself, making impossible for a 3rd party to guess how much money you have sent and to who. In the account model transaction are simler and clear, so less private.

More space=more transactions/smart contracts on the block

Because you can see who sends sth to who. While in Bitcoin, you always have the option to send money back to you and make it unclear where the money goes.

  1. Less information is stored, meaning transaction sizes are smaller. More transactions can fit in a block, meaning lower fees and quicker transactions.

  2. Less traceability. He cannot find out where the Etherum has been previously or where it exactly came from.

more tx can be put in the block

beacuse you can not control where does the money came from or if it was stolen

  1. It is benefit because each transaction takes less space and network can handle more transactions per second.
  2. There is less privacy in the account model because it is transparent who is recipient of a transaction and this is due that there is no need for a change in the account model. In UTXO model is unable to see which coins were sent to other party and which were sent back to yourself.
