Homework on UTXO vs Account Model

Ethereum 101
#502
  1. It’s a benefit as the UTXO model requires a larger space, meaning that smaller transactions means smaller fees (per byte)
  2. because your account balances are public , account code is public .

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    small space is benefit for computing and network, make more efficiency.

  2. How is the account model not as great as the UTXO model for privacy?
    UTXO has all transactions history. it can trace every single coin/BTC history. But account model can only trace account level transaction not coin/ETH level.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    A: it is not stored on ethereum it only updates without inputs and outputs so less space and less privacy so everyone can see to verify

  2. How is the account model not as great as the UTXO model for privacy?
    A: it is fungible and tracing them is not as easy but UTXO makes it easy to trace and can not be fungible

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It allows a larger number of small transactions to take place. It takes less space on the blockchain network because the balance of an address is not considered as the sum of all its UTXOS. Rather, it in the account model the users balance is calculated as a whole, which decreases transaction fee/ byte and space.
  2. How is the account model not as great as the UTXO model for privacy?
    Due to the account model, everyone on the ETH network will know who is sending and receiving, whilst in Bitcoin the sender and receiver are kept anonymous.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    The account model requires transactions to record just the from and to account addresses with the debit and credit amounts. This will keep block size down, which should in turn increase transaction speed and keep fees lower.

  2. How is the account model not as great as the UTXO model for privacy?
    The account model only keeps the detail of your balance. Your account balance is set and is public. No account or balance information is held explicitly in the UTXO model, a wallet will aggregate all UTXOs that are assigned to you to work out a balance. The UTXO model allows transactions to have multiple outputs which can include yourself, enabling more privacy

  1. the less space a transaction requires the less likely that the network will be congested
  2. account model has a balace update model such as bank account. you can see exactly from where to where a transaction has been send. the UTXO model spends all unspend transactions on each transaction and sends back the change to yourself. Making it practically impossible for an outsider to distinguish which part is going back to you and which part is going to person B, C, D…

  1. The account model is lighter and faster.

  2. The account model means that individual accounts can be identified more easily and trails of transactions can be followed. The UTXO model is harder to unpick as there are lots of UTXOs linked to different wallet addresses, many of which are controlled by the same user.

  1. smaller space means less byte, means less fees for transactions
  2. easy to follow tx because accounts are public

Etheruem keep track of balances in method that doesn’t required all the tracking of UTXO model. The Eth model is fungiable (easier to perform exchanges).

How is the account model not as great as the UTXO model for privacy? In the UTXO model we can send funds back to ourselves on a different address, which makes it difficult to track.

1 less space less energy

2 btc the input=output the output can go to different adresses which can in control of anybody
eth is just the balance + or -

You can pack more transactions into a block (smaller transactions, slower growth, smaller fees per byte)

    in ACOUNT MODEL: Account balances and codes are public. fungible, CANT obfuscate
    in UTXO: non fungible, CAN obfuscate.

1.It is easier to express in code than the UTXO model because it needs fewer space.

2.Because you can not send ETH in one transaction to multiple addresses which some or all could belong to you like it is possible with BTC:

  1. Less space is required in each block and therefore cheaper/faster to complete transactions, more space for smart contracts.

  2. Transactions aren’t easily traceable and harder to detect fraudulent transactions.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    One block can store more transactions, resulting in faster and more efficient transactions.
  2. How is the account model not as great as the UTXO model for privacy?
    With the account model you can see the amount and the account which has accepted transactions. The UTXO model allows you to send a transaction to multiple addresses without showing at the same time to whom the payments belong.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It makes each coin the same, thus fungible and size of transaction is smaller
  • How is the account model not as great as the UTXO model for privacy?
    Because you can track who sent what to whom

    Faster transaction times, lighter data exchange.

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

Because transaction is on an account by account basis, this makes it easier to track as opposed to UTXO’s which can have multiple outputs in one transaction.

2. It is easier to tell from which account ETH has come from, however you cannot see which ETH is associated with any particular transaction unlike bitcoin and so has fungibility - all individual ETH are indistinguishable from another. In bitcoin, if a BTC is associated with a particular crime, it can end up being not as valuable as a clean BTC as it can be traced to that crime and hence may make it harder to sell eg if it is banned from particular exchanges as a result.

    The smaller the transaction the slower the bolck files grow which also results in smaller fees per transaction or byte
  2. How is the account model not as great as the UTXO model for privacy?
    All balances are public and trx’s can’t be sent with privacy in the same way they can with btc utxo’s (ie fake transactions)
