Homework on UTXO vs Account Model

Ethereum 101
#2769

  1. because more transactions will fit in a block, quicker transactions, less storage etc.

  2. because you can directly see which adresses your transactions go with a account model. with Utxo you always “spend” all your UTXO’s but nobody knows how much goes back to yourself

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

  2. How is the account model not as great as the UTXO model for privacy?
    There is an actual “account” that belongs a private key with all their information and is it easier to track then UTXO’s who can send funds to self.

  1. With the account model the benefit is more transaction while using the same amount of data.

  2. You can not split transactions to have different outputs, account model is a direct path.

  1. Space savings is a benefit as it results in cheaper transaction fees and faster times. Lower data requirements = more potential participants. Blocks can include more transactions which is beneficial for ETH as thousands of ERC20 tokens are created on ETH blockchain.

  2. There are no change wallets in Ethereum. The destination addresses are the ones originally specified. Bitcoin, on the other hand, sends any unspent UTXOs to a “change” wallet, and it therefor is more difficult for someone to know which of the addresses sent to are new individuals vs the sender’s change wallet.

1.) The benefit of the account model is the decrease of needed space on the blockchain for every transaction and services.

2.) The account model allow it to follow easily all transactions that an account did and to which other accounts the transactions were sent. In the UTXO model transaction recipients are almost invisible or not traceable.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    A) Increased efficiency being able to store more TX’s

  2. How is the account model not as great as the UTXO model for privacy?
    A) You can see from which account someone is sending to which account is receiving it reducing security.

  1. The account model takes up less space which means there is more space for more transactions on the blockchain.

  2. The UTXO model has transactions being sent from you and back to you as the sender in such a way that from the outside you cannot distinguish who is sending who Bitcoin.

    You can fit more transactions in a block
  2. How is the account model not as great as the UTXO model for privacy?
    You can see from which address the ETH has come from but you cannot see the transactions before that.

    A. smaller block size means smaller fees. More TX in block means shorter confirmation times.
  2. How is the account model not as great as the UTXO model for privacy?
    A. accounts are made public.

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

It is a benefit because the transactions are simpler and become easier and quicker to process in the blockchain.

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

The account model lacks privacy in comparison to the UTXO model because it is possible to verify the sender’s and recipient’s address for every transaction, whereas the UTXO model doesn’t reveal that information as precisely.

The Account Model reveals an address’ balance, which the UTXO model does not do.

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?
    It is considered a benefit because it takes less space; there is no tracing back like UTXO notion.
  2. How is the account model not as great as the UTXO model for privacy?
    It shows where the money is going from just looking at the transactions unlike UTXOs that you may be actually sending yourself changes but it cannot be seen from looking at the transactions right away.

  1. Less weight results in less fees per transaction.
  2. Because the account model shows exactly where a transaction originated and where it ended up whereas in the UTXO model, several inputs can lead to several outputs making it unclear exactly which UTXOs belong to a given entity.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    By that you can fit more tx in a block.

  2. How is the account model not as great as the UTXO model for privacy?
    In UTXO you can follow the trace of any coin up until its origin, while with the Ethereum account model you cannot see that far but only who sent you the Eth.

1.) It simplifies transactions.
Nodes and Blockchain need to store less.
With smaller transactions there are smaller fees.

2.) A transaction has one Input and one Output which is stored on the Blockchain. By that everyone can theoretically see where you have sent ETH to.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
Less space is beneficial because you can fit more in one block.

2. How is the account model not as great as the UTXO model for privacy?
In UTXO you can not see what amount you are sending to someone else and what amount you are sending to yourself also you could be sending everything to yourself in a different wallet address.

In the account model, you are sending the funds directly to recipient.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? - it means you can fit many more transactions into a single block.
  2. How is the account model not as great as the UTXO model for privacy? - you cannot send anything back to yourself. in the ETH model you cannot go back UTXO per UTXO to see where the money is coming from, you can just see which account sent you coins.Basically you do not have the same traceability.

  1. It saves storage space on the blockchain. It’s less complex.

  2. It is clear to see which address sent how much of what to who using etherscan.io. So while all transactions are visible, the provenance of tokens cannot be verified. Whereas with UTXO’s you can see their journey since being mined to the present day on the block explorer.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    You can fit more transaction on each block

  2. How is the account model not as great as the UTXO model for privacy?
    In the account model you have accounts where you send transactions to, and it is easy to trace these transactions.
    In bitcoins it is easier to create new address, so in this case you can send UTXO to new addresses.

  1. The account model is smaller in size, which allows for slower growth in the block chain, and faster transaction times.
  2. The account model is open for public viewing on the block chain. So with this model, there is a one for one transaction that if viewable, vice UTXO where you can have multiple addresses on one transaction.

  1. Saving space is always a benefit. You can have more transactions, it is lighter.

  2. You can’t send funds to your self and funds go from 1 account to other account. It’s easier to visually follow.
