Homework on UTXO vs Account Model

Ethereum 101
#3631

  1. Because it requires less blockspace in the blocks so it contributes to improve the block size issue.

  2. Account model manage each transaction sustracting value for a wallet and adding the sustracted value to another and it is shown as an only transaction. With the UTXO model the transactions may be shown as several outputs to different wallets even if one of the address is you own wallet, therefore, you can not say which transaction is the “real” one.

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

Less the space requirements more the transactions can happen on the blockchain. Many dapps are running on top of Ethereum blockchain and those dapps are running many transactions. Less space is beneficial for the blockchain overall.

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

In the account model, transactions are simpler, from account A to account B. There is no multiple outputs like the UTXO model where you can send something to someone and send to yourself something at the same time. Any observer of the transaction wont be able to know if you send something to yourself. So the privacy is a bit less in account model than UTXO model.

Not needing to rely on UTXO is crucial for scalability, because Ethereum is a platform where more and more tokens are being made, some of whose primary appeal is based in the expediency that large block sizes can not accommodate.

The account model, however, sacrifices some security for speed, as you can more precisely trace the single transaction output - as opposed to the multiple UTXO output which is a tracing of the entangled transactions more than a streamlined ledger with a clear, discernable address.

  1. The blocks can contain more transactions making the smaller and easier to transfer. It is also a simpler model.
  2. it is possible to track transactions since you can’t send money back to yourself in the same transaction that you use to send money to someone else. This makes the transaction easier to follow.

  • More transactions can be accommodated in a block
  1. How is the account model not as great as the UTXO model for privacy?
  • It is easier, more straightforward to identify the movement of the funds to and from a certain address down to the exact amount of coins spent.

  1. The account model allows for more transactions per block.
  2. The account model doesn’t allow for obfuscation where I could send bitcoin to someone and myself. In such a transaction you cannot tell which public key received which percentage of the transaction. Where in Ethereum the transfers are clear in who receives what.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? It allows for more transactions and faster transactions.
  2. How is the account model not as great as the UTXO model for privacy? Because your transaction clearly shows what was sent and received rather than having multiple accounts between which you can’t distinguish.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    As each transaction requires less space, each block can contain more transactions increasing speed and decreasing costs.

  • How is the account model not as great as the UTXO model for privacy?
    In the UTXO model you have the possibility to obscure transactions by sending funds to yourself as a part of multiple transactions.
    In the account model a transaction goes from one wallet to another wallet and are easily traced.

1.less storage space is needed making for more transactions per block and each node not needed as much storage to keep the state of accounts up to date.
2.it is slightly less private as addresses can be seen where eth was sent from it cannot be disguised as it can with multiple outputs in the utxo format.

1- Account model takes less space that means more transaction can take at the same time and user have to wait less for them.
2- Account model is very simple to track because it has one single input and output while in UTXO model their are multiple input and output in every single transaction thats why UTXO model is good for privacy in compare of account model

  1. Because smaller size block can make things faster. Miners dont have to use so much power which is environmental friendly and also reduce its size also increase the usability & friendliness when adopting it.

  2. Because account model are very easy to trace from 1 account to another account together with the amount whereby UTXOs can have multiple inputs & outputs and I can be in both inputs & outputs in a single transaction.

  1. It makes transaction time rate faster because it’s used to process transactions from A to B without using the UTXO model which can include several inputs and outputs for a single order or transaction. UTXO model uses more space for each transaction, while the account model just processes one-by-one transactions for each instructed action.

  2. Because of the traceability of transactions. On UTXO, the sender can be the recipient and use the inputs and outputs to send and received transactions that won’t be traceable after being processed in different stages of blockchain. In the case of the account model, it tracks and registers the A to B transaction in the network and shows the balance of the account.

    Transactions take up less space so more transactions can occur at a faster pace.
  2. How is the account model not as great as the UTXO model for privacy?
    The account model easier to trace were transactions come from and where they are going. UTXO is harder to track because there may be many inputs and outputs.

  1. Each block can hold more transactions and more complex code, increasing scalability and efficiency, and decreasing cost
  2. The account model only allows for a direct transfer on account balances unlike the UTXO model where you have the ability to send different amounts to multiple accounts, including you own, within the same transaction making it harder to trace on the blockchain

  1. This makes it easier on the block to create faster transactions. Easier for scaling, unlike Bitcoin that had issues in this area.

  2. The UTXO model is more discrete when it comes to transactions. You could send a transaction to someone while sending Bitcoin back to you. This makes it less transparent on what is going on in the transactions. Eth being a fungible token all it does is update wallets to the new balance. But one could fallow the path which leads to one wallet for one transaction.

  1. Less space means more transactions can be included in a block. Overall it would make processing faster.

  2. Account model is not as great because when transactions are sent they are delivered to a single address. As a result it is easier to pin down the source of that single address versus a UTXO model where the UTXO’s can be delivered to multiple addresses in one transaction and one can potentially mask their transactions if they wanted to.

  1. It would be a benefit in ether’s case because it allows more room on a block to store SC’s and the state of them on the network.

  2. Makes ETH fungible, you wouldn’t be able to trace back the origins of the transactions of single ETH and there is a now record of what each wallet address of a balance each wallet would have.

  1. The account model gives less info and takes less space to write as code, freeing up more space on the blockchain.

  2. The account model doesn’t obfuscate the accounts through which money is being sent and received, including the amounts. It can’t hide which amounts are sent out and which are returned to the original address for example. On the other hand, while UTXO’s can somewhat obfuscate how much of each payment is going to whom, their structure makes bitcoin less fungible. This makes some UTXO’s that were used as ransomware etc become “tainted”, similar to marked bills that get flagged in circulation.

  1. Because, the account model relies on balances but not outputs. It’s just a matter of addition and subtraction, so no traceability is required like the UTXO model. This also increased the txn speed.

  2. In UTXO every BTC can be traced to its origin, from the time it has been mined. You can create multiple txns in the UTXO model and it’s just gonna take so much time and effort to manually track all outputs with all that lengthy hashed addresses. Whereas, in account model you just know where the balance came from and who has it gone to.

  1. Because with account model the transactions are less clunky and you get the computation outcome faster, and increase scalability of the network.

  2. because with account model it assumes that for every debit there is a credit - and each transaction is traceable on both the sender and the receiver end.
