Homework on UTXO vs Account Model

Ethereum 101
#764

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It makes the blocksize much smaller and this improves the transaction time a lot.

  2. How is the account model not as great as the UTXO model for privacy?
    Because there is no way to “hide” a transaction by sending coins to several addresses in the same transaction like in bitcoin. An ethereum transaction does not have any outputs.

:+1: thanks for elaborating on the topic here

  1. Less data to work with resulting in less time to transact

  2. Because with utxos you can track where the transactions came from right back to where it was mined. With ETH you can see from the outside what address you are sending money to on the BC

  1. Less space used on the Account Model allows for more transactions to be included in blocks.

  2. The Account Model reduces privacy of transactions, as a balance is transferred from one account to another (i.e. person A has 10 Eth, who sends 1 Eth to person B = balance for person A would reduce by 1 & person B’s balance would increase by 1). This makes it easier to track who received a transaction & which address it came from.

  1. It makes transactions a lot faster. And more transactions per block

  2. There is no way to hide where you send the currency to. It’s like a balance. Send x to recipient y . With bitcoin you can send bitcoin back to yourself in the same transaction

  1. Transactions need less storage space in the blocks and can be processed faster and cheaper.
  2. It is easier to trace the transactions, because there are no multiple outputs within the same transactions. Ether is always transferred from account A to account B.

  1. it is faster, more transactions in one block and taking up less space
  2. with the BTC model you can send BTC to your own wallet where it is not visible that this is that specific account. With ETH the transactions go to specific accounts.

more txs fit on a block, process faster

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

Account model is less private, can clearly see where each tx is going or coming from, no way to obfuscate the txs, no outputs on Ethereum just updates

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 block chain size can be fractions of the size
  2. How is the account model not as great as the UTXO model for privacy?
    On account of you not being able to hide your transactions as you only have transactions that can be added or removed

  1. Because such extra space can be economized for other uses (e.g. more transactions and transactions are smaller).

  2. The UXTO model can have multiple outputs/destinations (including one from the sender) which can’t be tracked (or easily spotted). Meanwhile, the account model uses a one to one transaction method and therefore it is easier to trace --> less privacy.

  1. More transactions / block, faster transactions, less data to broadcast between nodes and maybe cheaper?

  2. A bitcoin transaction can have multiple inputs and outputs and there is no way of telling witch outputs went back to sender. This is not the case wit eth as you send an exact amount and account balance is updated with that exact amount.

  1. It is way simpler model. Less space - faster transactions.

  2. There is no way to send money back to myself or give myself some change in one single transaction . You can track the address.

    It reduces the space for tx on the blockchain, improving the performance of the Etherium solution.

  2. How is the account model not as great as the UTXO model for privacy?
    The Etherium Transaction it has who sends to who, A sends to B, leaving it expose the acct that send, the accts that receives and the amount.

    More transactions per block can be stored.

  2. How is the account model not as great as the UTXO model for privacy?
    Unlike a UTXO that can be traced back through the blockchain the account Ethereum is more fungiable.There is no way of determining one individual ETH from another.

  1. Because there is no tracking involved like UTXO’s which traces the origin of all the way back to the coin creation or UTXO start. This is a benefit because it free’s up space in the block
  2. In the UTXO model within one transaction there are funds sent to a seperate account and also the change back to yourself but its indistinguishable as to which account is yours so thats where the privacy aspect comes into play. With ETH its clear who sent what to what account there is no concept of change being sent in addition to sending funds to someone else.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Less space means more transactions can be executed. It helps clear out space in the block.
  2. How is the account model not as great as the UTXO model for privacy?
    Bitcoin TX can have multiple inputs and outputs. It is infeasible to tell which output went back to the sender. This adds privacy and security to the blockchain. But, Ethereum account model it is possible to know the exact amount and account balance that is updated. ETH is fungible which means less privacy.

  1. Less space means the model is simpler, easier to express transactions on, faster, easier for a distributed network, more storage.
  2. In the account model, one account is debited and another credited so there is no anonymity as there can be in the UTXO model which permits sending of a transaction to various addresses from different sources.

The account model doesn’t require as much space as the UTXO model, why is that a benefit?
Some benefits of less space required can be faster processing, a greater amount of available functions, and faster potential adoption by users who can engage with less processing and memory requirements/costs.

How is the account model not as great as the UTXO model for privacy?
The account model displays the balance and adds or subtracts from involved accounts. One ETH equals one ETH. So, it is easy to see what accounts sent and what accounts received. UTXOs do not display collective balances; all UTXOs must be added together to come up with a balance. One BTC does not necessarily equal one BTC. UTXOs can trace history back to individual coins. One BTC could be less quality, have been involved in nefarious activity, or been connected to criminal activity compared to another BTC. The sender can combine UTXOs and recipients so that it is extremely difficult or impossible to identify which transaction goes to a specific account. Overall, making UTXOs much strong with respect to privacy.
