Homework on UTXO vs Account Model

Ethereum 101
#3170

  1. It leads to a simpler blockchain model that can handle more transactions, and therefore, more demand.

  2. The account model makes it very easy for someone to track funds and the address of the recipient. With the UTXO model, one can send bitcoin to multiple addresses, with potentially one of them being your own. In this case, one cannot distinguish which address is the recipient because of the multiple outputs.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit? Becasue it allows for less congestion in the network and leaves room for other functions.

  • How is the account model not as great as the UTXO model for privacy? In the account model if you check the blockchain you can see that 3 eth was sent to “A” and in the UTXOs you really do not know how much was provided

  1. Results in faster transactions due to smaller blocks
  2. It is easier to trace the balances. In the UTXO model the coins are not fungible

  1. It is a benefit because it leaves more storage for more smart contracts on the blockchain
  2. because you can see exactly how much you sent and to who

  1. This is beneficial because it potentially means less data, lower costs, and hopefully more users.
  2. It is easy to see who has been paid from where so less privacy vs UTXOs which is more difficult to see because of the presence of more outputs.

  1. Because it allows the blockchain to go faster and nodes available for other functions. Also, it helps a fast update of blances in wallets.
  2. The account model lacks a bit of privacy because you can’t send back money to yourself. And most importantly, it is extremely fungible, which means that 1 ETH = 1 ETH always, and you can’t differenciate between coins, this allows you to see wallets movements, but not the exact precedence of the coin, while with UTXOs you can track the exact UTXO and know from where to where it has been send. In the case of the UTXOs you can block a UTXO when it comes from a scam, and in tht case 1 BTC won’t be the same as other BTCs.

I.It means that transactions take up less space and as such blocks can include more transactions✍🏾
II.Faster settlement time, and lower fees :writing_hand:t5:

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

In the UTXO model, you can muddle/ obscure your transactions by sending funds back to yourself(a wallet you own) as well as to others(wallets owned by other people) i.e the possibility of one transaction with multiple outputs. With the Account model however account balances are visible and it is possible to determine who(as in, which account) sent funds, and who(as in, which) account received funds :writing_hand:t5:

Space savings is a huge benefit, transactions take up less space and blocks can include more transactions also it provides faster settlement time, the lower the data requirements the more potential participants.

The account model is not as good for privacy as you can track the address of who has been paid, whereas the UTXO model can pay out multiple accounts one of which can be your own.

  1. This allows less data stored and more computational power available which is important since Ethereum is executing smart contracts rather than just tracking and storing transactions.

  2. The account model has a more linear and therefore trackable transactions while the UTXO model in bitcoin can be more difficult to track where funds are being sent to.

Because it allows more and faster transactions

How is the account model not as great as the UTXO model for privacy?
The UTXO can send multiple transactions at the same time, which is not possible with account model. Thus, account model makes it easier to trace the balance of each account

    because the account model updates balances with each transaction, much less space is required on the blockchain and the speed of the transaction is increased.

  2. How is the account model not as great as the UTXO model for privacy?
    with the UTXO model you can pay someone and send money back to yourself without anyone outside of the transaction being able to tell which output went back to you. this is a privacy aspect which is lost with the account model.

  1. The account model requires less less space than the UTXO model and this is a benefit since less space requires less data requirements allowing for nodes to operate faster when syncing the entire blockchain. Reduce transaction times, increase efficiencies, and thus costs can go down.

  2. The account model is not as great as the UTXO model for privacy because you cannot send money back to yourself nor give myself change from a transaction. Which can be done in the UTXO model but since no one can say who the owners are of those addresses the transaction can be deemed more private. In the account model these transactions cannot be done therefore your transactions are slighly less opaque and thus more interpretable meaning a bit less private. You can see which transactions where made from where to where in the account model.

More transactions can be used in a block, which is critical for ethereum, which also has hundreds of ERC20 tokens settling on the ETH blockchain.

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

It is less reliable so you can see which accounts it comes from and which accounts it goes to.

    Nodes have lower hardware requirements (memory) which supports decentralization

  2. How is the account model not as great as the UTXO model for privacy?
    The scheme is much simpler (you have no back references to your account) and is therefore easier to track

  • Less space required for each transaction
  1. How is the account model not as great as the UTXO model for privacy?
  • For the UTXO model, you can send to multiple addresses within one transaction.
  • For the account model, you can only send to a single address per transaction.

  1. less space and more efficient
  2. u can track eth but btc is more secure because of utxos.
#3186

  1. In this way the transactions are faster and cheaper and the block needs more space for tokens and smart contacts like erc20.

  2. In UTXO model you have more options in tx, for example you can send to multiple addresses btc in one transaction that means you can lose track easier.

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

  2. How is the account model not as great as the UTXO model for privacy? No way to send money or to give back some change to yourself. Easy to track the transactions. Doesnt have many outputs like the UTXO.

You dont need much capicity to save the transaction

By UTXO you have many in and outputs, Eth only have one.

  1. More transactions can be stored in one block, which is an advantage in and of itself. A
    transaction is processed after receipt and is saved as an update. There are no open
    issues, so to speak.
  2. Everyone sees on the blockcain which address is sending and which address is receiving.
    An address cannot be both sender and recipient at the same time. (unlike bitcoin)
    The privacy is classified as very low or rather lower.
