Homework on UTXO vs Account Model

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    With Bitcoin and UTXO model, to get balance we have to make a search in the UTXO schema, to find all historic previous transactions, just to get balance.
    With Ethereum, there is just a number that stores the balance, and this is this value that is updated for each transaction happening to our balance, it’s easier and so it takes less space.

  2. How is the account model not as great as the UTXO model for privacy?
    In Ethereum, there is a one to one, while making a transaction ; so you know the sender and you know the receiver.
    With UTXO, you have a one to many, so it’s good for getting a better historic transactions and good too for privacy.

    The less space it takes, the more transactions can fit in a block, so it will be faster.
  2. How is the account model not as great as the UTXO model for privacy?
    Because you cannot send back money to yourself, but instead the exact amount you need to pay others. In UTXO you can make it show like you are sending to someone else, but in fact it is you but with different address.

Using less space allows more transactions per block

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

It is easy for anyone to see on the blockchain exactly how much you have and who its was sent to. Unlike bitcoin transactions it is impossible to send transactions to yourself and somebody else in a way that makes it impossible to know who got sent what. This makes some bitcoin transactions less traceable. The Ethereum blockchain shows balances on chain and doesn’t require a compiler program built in to your wallet to compile all the UTX-0’s you can spend and add them all up.

  1. the account model just update transection rather than using the input and output method. this method uses less space bacause the transections are smaller

  2. the account model and trace address of the payee and payor. where UTXO can be pay to serveal address and the detail is unknown.

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?

Because it shows a balance of all coins where is not possible to “track” it back as UTXO in the Bitcoin blockchain and transactions are simpler. For example, I wanna send 1 ETH and I send 1 ETH but in BTC where I wanna send 1BTC, it doesn’t mean that input will be 1BTC it depends on UTXOs it could be maybe 2 maybe 10 UTXOs to send 1BTC so that takes much more space in tx.

  1. How is the account model not as great as the UTXO model for privacy?
    It’s a simple transfer from A to B in the required amount without a change and it is not as complicated as in the UTXO model

Takes up less space in the blocks resulting in more transactions per block.
2. How is the account model not as great as the UTXO model for privacy?
You cannot make multiple output from one transaction to hide what amount goes to a target wallet belonging to yourself and ones that belong to others.

  1. Less space means more txs per block, which implies a faster network.
  2. You can trace a UTXO, but you cannot tell who is receiving the funds. In the account model, senders and recepients are known.

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 is a benefit because now it takes less time and less space for the Ethereum network to function.

  2. How is the account model not as great as the UTXO model for privacy?
    Since transaction do not contain inputs/outputs in the account model, there is no remaining balance that is sent back to the sender. Therefore it is quite simple to identify which transactions are sent to which addresses.

Blocks can include more transactions less latency

With the account model, you can see and follow every transaction. It the UTXO model, you can have several outputs at the same time which can be more private

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

It save space so it can be executed faster. Wallet does not need to count a balance then send the amount to the target account. The ETH chain transactions are more fungible too, because only the basis and target account and the amount of money involved in a transaction. In UTXO model different small pieces of values are involved and if one piece of value is shady it my not be spent in the future. So it is not as fungible.

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

It is not as great because in the account model the basis account, the tartget account and the amount of money are involved. This let individuals to map the trace of money more easily than in UTXO model.

You can add more transactions in the block, and they can be processed faster

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

you can trace each transaction from who to whom one input and one output, in a UTXO there are multiple outputs and you won’t know to whom they all are

  1. The account model doesn’t require as much space as the UTXO model, why is that a benefit?
    The account model is build around the fact that each TX updates the accounts. There are no inputs and outputs that can increase the size of a TX. That means more transactions in a block, and a greater potential for network scalability.

  2. How is the account model not as great as the UTXO model for privacy?
    In the account model, you can not create a TX where you send money both to yourself and some else. Also, you can not get change back.

Because you only have to say to the network that you are sending to another account, while with UTXO you sacrifice space for security/privacy using more complexity

Because everyone know how much are you sending anywhere. with UTXO it’s different

  1. It increases its scalability as you can put more transactions into a single block.

  2. You cannot obscure where you are sending your Eth.

    Less information to store, hence transactions take less space

  2. How is the account model not as great as the UTXO model for privacy?
    UTXO you can send coins back to yourself in same transaction as sending to someone else part of coins making it harder to know what coins one account actually controls. In account model you can trace exactly what an account holds, thus less private.

    With more space and each transaction Transparent and Smaller, the Blockchain has better storage capabilities, decentralisation, and Adaptability.

      The Account Modal Provides global, full read Permissions, Tracking Trasactions of account balances and Transactions of User Address’s Providing a Secure, but Transparent Model.

  1. The smaller the data space the esear it gets for to be a node, considering that nodes often are individuals and they keep the system alive. Also it makes Tx faster.

  2. Its easer to trace the Tx form where it came and where it gos.

  1. Without the UTXO’s, less space is needed for Ethereum transactions. This seems to be a benefit for speed.
  2. With the account model, you can see what account gave you money, however after you receive said money, it becomes one with everyone else in the account. With the UTXO model, you still have the ability to track said money, even back to miner if one wished. You could use this model with UTXO’s by sending two branches of money in a transaction, for example you could send an account money, and also send yourself money in the same transaction. There would be no way for an onlooker to tell the difference when viewing the transaction.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
This is a benefit because transactions are smaller/take less space than Bitcoin transactions.

2. How is the account model not as great as the UTXO model for privacy?
With Ethereum, you can always track exactly where ETH came from/sent too, you don’t have as much privacy as UTXO has with sending Bitcoin back to the same wallet during a transaction.

Answer 1 - Because Account Model don’t need to store all UTXOs and it only stores balance from transactions hence saves space which also allows block to use less space for storage and can store more transactions/data

Answer 2 - In Account model it is possible to see the flow of transaction from sender to receiver
