Homework on UTXO vs Account Model

  1. its a benefit because that means we can fit more transactions in a block therefore it may be cheaper and faster.

  2. The account model is easy to visually follow whereas the UTXO model can have many outputs including sending back to self.

  1. The more space available the more transactions can fit into block
  2. The UTXO model - part or all of the transaction can be sent to yourself or someone else, there’s no way to tell from the outside. The account model - there’s just a balance change, the transaction is easier to see.

  1. Blocks can have more transactions. This is crucial as the Ethereum Network has hundreds of ERC20 tokens.
  2. Because you can trace back to the address that has been paid whereas in UTXO multiple accounts can be paid which one can be your own.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Space saving is vital to a platform as large and complex as Ethereum, makes the use of its applications and smart contracts more efficient.
  2. How is the account model not as great as the UTXO model for privacy?
    In UTXO you can send funds to someone else and at the same time back to your own wallet without it being linked to you as a person. No one call tell which transactions goes to which wallet. In the account model you can only send one exact amount to somebody and everyone will be aware of where you sent it.

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

Every transaction is smaller, so blocks can include more transactions and nodes can process those transactions much faster than with the UTXO model.

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

The account model doesn’t allow you to send some Ethereum to yourself and some to someone else like the UTXO model does with BTC. The funds go from one account to another account, making it easy to see who the funds came from and where they’re going to.

  1. More transaction can fit into a block which will result in shorter transaction time.
  2. Because you can’t send ETH back to yourself on a specific transaction as you can do with BTC. The ETH goes from one account to another which is easily tracked.

  1. This would be a benefit, since less space will be needed in any given Ethereum blockchain. @filip I’m so sorry but I’m not too sure how else this would be a benefit other than saving space, maybe speeding up transaction confirmations? Or allowing the blockchain to contain the other bits of relevant information like data on smart contracts or the state of all smart contracts? Help :cry:

  2. Because the account model specifically identifies each party in a transaction by displaying movements in every Ether owner’s account, there is little anonymity in terms of who owns Ether, or where it is going. In other words, if Ether is transferred somewhere, there is a corresponding account that receives it - and this account will have na corresponding owner (who can theoretically be identified).

    Considering the number of transactions stored on the chain, the less space transaction takes the more transactions the chain can put through. UTXO model is slower and more expensive.
  2. How is the account model not as great as the UTXO model for privacy?
    The account model has less privacy because you cannot send coins to yourself.

It takes up less space and has a greater storage capacity. One block can store more transactions, increase storage efficiency.

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

The account model is not as great as the UTXO model for privacy because there are no outputs. Each transaction can be seen from the outside, how much was sent and to whom. UTXO model is hard for public to tell which amount of money goes to where, because one transaction could have multiple outputs.

1 - The account model blocks can include more transactions
2 - UTXO model can pay out multiple accounts, one of them can be your own

  1. Blocks can do more transactions and transfers are faster.
  2. Because you can exactly what will transfered between accounts. With the UTXO you can´t see it always.

  1. Less block space per transaction may equate to less cost per transaction.

  2. Without “change” wallets it is clear which address was the sending and which was the receiving for a given transaction.

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

  • Simplicity — Ethereum opted for a more intuitive model for the benefit of developers of complex smart contracts, especially those that require state information or involve multiple parties. An example is a smart contract that keeps track of states to perform different tasks based on them. UTXO’s stateless model would force transactions to include state information, and this unnecessarily complicates the design of the contracts.
  • Efficiency — In addition to simplicity, the Account/Balance Model is more efficient, as each transaction only needs to validate that the sending account has enough balance to pay for the transaction.
    2. How is the account model not as great as the UTXO model for privacy?
    With the account model we can see the amount of eth sent to any address.

Smaller transactions means smaller fees.

2. How is the account model not as great as the UTXO model for privacy?
In account model, addresses of who has been paid can be tracked as one input corresponds to one output.
In the UTXO model it is harder to track: you can have several inputs and several outputs at the same time. Transactions are mixed and obfuscated.

It makes the each coin more fungible because there’s no history of outputs.

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

UTXO allows you control over your outputs and there is no way to tell where each output is going.

  1. You can put more txs in a block.
  2. Because in UTXO model, you can create multiple outputs. The real transfer is hidden among the others and you can only guess the real transfer from outside.

  1. Speed. Less time to execute.

  2. You can see what wallet was used to send crypto through all transactions to get there. One input and one output.
