Homework on UTXO vs Account Model

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

Transaction takes less space it is a simple model less private. Each transaction just updates account.

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

Account model can not sent money to multiple address in one single transaction.
In Account Model you can see which address is getting the money. UTXO Model can send out multiple payout in one single transaction and on the outside no one will know who received which output.

Less space means higher speed.

With UTXO, you could send money back to yourself.

    1. Due to the fact that the account model requires less space, it frees up volume for more transactions per block.
    1. The account model allows you to send exact amounts to the recipient, and only one amount per TX. Thus you cannot send money to yourself and the external recipient at the same time.

1/ the Ethereum model doesn’t remember transactions, it simply updates balance account in suming the movement (debting or crediting), as opposed to Bitcoin model, which keeps tracks of any transaction: the latter consumes far more energy, room, etc…to keep all these infos, as first one keeps one balance and addresses (sender, recipient, qty, datesof transaction)
2/UTXO model like Bitcoin allows to create outputs for multiple recipients, including ourselves, and from multiple inputs: privacy is then larger than in a simple once a time movement on ethereum.

  1. If transactions require less space this will lead to a faster transaction, blockchain infrastructure will be better used and this is a real upside as the ETH network is very big.

  2. In the account model you can see you much money you have sent and to whom you’ve sent it. While in UTXO is harder to track transactions.

Answer: saving space ensures that more transactions can be packed into the blocks and sending the tx is faster

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

Answer: there is no way to send you money back and each tx is exact traceable you exactly who sent the money and where it was sent to

    One block can store more transactions, increase storage efficiency.
  • How is the account model not as great as the UTXO model for privacy?
    It is easy coins come from and where you send coins to a UTXO model is hard for public to tell how many coins goes to where, because one transaction could have multiple outputs.

It takes less time for computing transactions.

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

Account model does not have inputs and outputs, only incoming and outgoing transaction and current balance, which is not so great for privacy.

Because less space taken for transaction give more space in the block for code and state of the Smart contract.

Because you cannot send in one transaction funds to someone else and back to yourself like in UTXO model.

  1. As the account model doesn’t require as much space as the UTXO model, it generates higher speed as well as room for more transactions in the block.

  2. The account model is not as great as the UTXO model for privacy because you can’t see who has sent the transactions and who has received it. It is also not possible to send multiple transactions at once, which makes it is easier to track.

Can store more transactions in a block. Which is better for scalability.

utxo can mask their outputs so essentially you can move your bitcoin more privately and or to yourself.

  1. You can take more tx’s in one block. Means the transactions is faster confirmed and done. That also means maybe lower transaction fees?

  2. Because in the UTXO model you can send the money back, so noone will understand what send you whom. And also in Account model you have like a balance. Everybody knows when you receive from whom.

  1. It saves blockchain space to produce more transactions.
  2. You can track down the address of who sent funds, with UTXO that is not possible since it has multiple outputs.

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

The transactions are smaller in the account model, which means they are cheaper and faster.

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

It is very difficult to figure out who is sending and receiving funds in the UTXO model, partly because one transaction may have many outputs, including back to the sender. This is not possible in the account model. Etherscan shows a ledger of transactions, which are easier to read as they are one to one, and the balance of each account is adjusted accordingly.

    transactions are smaller and retreiving account balances are easier

  2. How is the account model not as great as the UTXO model for privacy?
    with UTXO you never know who is receiving the different balances, but with account model there is only one recipient.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? - it takes up less space on the blockchain, and are easier to compute,
  2. How is the account model not as great as the UTXO model for privacy? the UTXO model requires you to output all your UTXO so every transaction has at least 2 outputs your receiver and yourself with the balance this makes it harder to know who is getting what. With the account model you have fewer outputs meaning your transaction cannot be as easily “disguised”.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
• Account model allows for smaller transaction sizes and the blockchain node file doesn’t increase as quickly as a blockchain with a UTXO model.
2. How is the account model not as great as the UTXO model for privacy?
• The account model only allows a user to send a transaction to someone else, or to a different address you own. You cannot do both. On the other hand, in the UTXO model, you can do both. A user can send multiple transactions to themselves and others. This enables users to hide who they are sending funds to.

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?
    -This saves space on the blockchain and allows more transactions to be fit in a block

  2. How is the account model not as great as the UTXO model for privacy?
    -In the UTXO model transactions can have multiple outputs and so one can send back transactions to self owned wallets which may be untraceable, whereas in the account model transactions will only be moved by updating numbers on the blockchain .

  1. Faster transaction speed, lower transaction fees.

  2. In the UTXO model, you can not know which address belongs to whom. In the account model you know where the money came from and who it was sent to. The UTXO model can also know if the BTC came from a dishonest means like a scam or a hack, so it may be harder to spend, whereas the account model can not. ETH acquired by a scam or hack would not be know to the recipient. So, it would be more discouraging to scam/hack someone for BTC as it would be less discouraging for a dishonest person to scam/hack someone for ETH.

  1. Space saving is a benefit as it leads to more efficiency on the blockchain and reduces power required to for full function. As the full nodes are meant to be operated by individual miners rather than mining data centers, the lower the data requirements the more potential participants. which makes a securer network.

  2. An individual cannot send funds to themselves.
    coins go from one account to other account. It is more user friendly and easier to manually track.
