Homework on UTXO vs Account Model

  1. Any space savings is a benefit. As the network full nodes are meant to be operated by individuals rather then data centers the lower the data requirements the more potential participants.
  2. Easily to know where the money come from and where you send money to. UTXO model is hard for public to tell which amount of money goes to where, because one transaction could have multiple outputs.

  1. Smaller or less space equals to faster txs. Capable of more txs per minute.

  2. The account model adds all balances and is public, whereas The UTXO model is not Fungible(Not Distinguished)

1 - The benefit is that we can have more space for other data.

2 - In the account model it’s easier to track exact transactions from A to B. While in UTXO is harder to know who was the payee as 2 transactions are made. (one to the payee and one back to yourself)

The account model doesn’t require much space as the UTXO model, why is that a benefit?
This is a benefit because it requirer less space. It will make the Tx faster

How is the account model not as great as the UTXO model for privacy? Because you can’t sent change to your self.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? There is less transaction fees, and less advanced computers can handle the ETH network.
  2. How is the account model not as great as the UTXO model for privacy? Because the account model does not allow users to send money to another user and yourself at the same time in one transaction.

  1. It is a benefit as the transaction “weight” is much lighter as all UTXOs require a lot of space to be recorded.

  2. Account model is not private as in the UTXOs model you can send, on the same TX, some BTC back to your wallet, theoretically confusing any tracking. On the Account model you just have a simple movement of coins where 1=1 which makes it easy to track.

    It is a benefit for increased time for a transaction to completed and the size of the network

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

    You can see exactly who sent you an amount. It is visible that a transfer was made from point A to point B

  • This will make it faster

  • The account model simply moves funds from A to B which is very traceable. The UTXO model has inputs and outputs which allows you to send funds to yourself at a different address and increase privacy.

The more efficiently a blockchain runs, the more use cases can be programmed to carry out. Blockchain technology needs efficiency gains for mass adoption.

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

Transactions are generated directly from one account to another, so transactions are more traceable.

1.The UTXO model creates an environment where parallel processing capacity across multiple addresses is possible, enabling a much better infrastructure for scalability.

2.UTXO provides a higher level of privacy, as long as the users use new addresses for each transaction. With Ethereums transparancy you can see who sent to who and the transaction amount.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? It’s a benefit because it reduces block size.
  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 the TXO model can hide the origin recipient of a transaction wear as the account model all transactions can be viewed from the outside.

  1. Simpler and more flexible transactions.
  2. You can see who sent money and to whom as there are no multiple outputs as with the UTXOs.

  1. There is less space taken up on the blockchain.

  2. The blockchain shows the actual amount being transacted plus it also shows who own the addresses of the sender and the receiver.

  1. Because with less space required by the account model, one block can store more transactions, increasing storage efficiency (more space available). More transactions performed at the same time means greater scalability and in turn potential mainstream adoption.
  2. With Ethereum and its account model it is easy to know where the money comes from and where it is headed (from which account to which account), because there are no outputs. With the UTXO model, it is harder to discern which amount of money goes to where, because one transaction could have multiple outputs. In other words, the account model is much simpler (money goes from A to B), while UTXOs can be spent to multiple accounts.

Indeed, also the account model require less space than UTXO model because transactions are smaller in bytes, making each block more efficient and faster to mine in order to handle even more different type of data (like smart contracts transactions from dapps).

    Because you can fit more transactions in a block

  2. How is the account model not as great as the UTXO model for privacy?
    Because it is clearer to see who makes and receives a transaction

Because transaction execution, propagation, verification, and confirmation can take place more efficiently

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

Its so because the data structure and model purpose serves a different functionality

  1. Transactions take less space so there’s more simplicity, faster network I guess ?
  2. More fungible, there are just updates between wallets in ETH. big difference with bitcoin

It saves computing power

In the account model its much easier to see the balance of an account, so therefore you can track the wealth of users much easier

  1. Etherium’s account model doesn’t require much space as Bitcoin’s UTXO model. That is a benefit because each block takes up less space and has a greater storage capacity.

  2. Etherium’s account model is not as great as Bitcoin’s UTXO model for privacy because there are no outputs. Each transaction can be seen from the outside, how much was sent and to whom.
