Homework on UTXO vs Account Model

Ethereum 101
#2146

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Because we can squeeze in more data in each block, thus increasing BC performance, reducing fees and reducing network latency.

  2. How is the account model not as great as the UTXO model for privacy?
    With the account model, it is not possible to obfuscate the transaction.

  1. Less space for a transaction will loll for more transactions and more participants.

  2. Account model allows to track every transaction (less privacy). UTXO model allows several outputs at the same time and anomynous about the address and quantity that you send

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

-It allow for more data (transaction) to be store in each block. UXTO model require alot of storage space because of all the input and output. Account model update the balance within each wallet instead of tracing all the UTXO.

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

-UTXO can have two output with one transaction, making hard to identify which output (wallet address) belong to whom. Where as a model account you can’t do that because the total balance is stored in the wallet. When making a transaction it will just subtract from the balance and send the exact amount that is needed.

  1. The benefit is less data use per transaction means faster transaction speed in general.
    2.You cannot send funds to your same wallet and funds go from account to account, which is easier to follow.

Because blockchain size is a critical factor in the scalability of the model.

in UTXO model there are ways to avoid leaving traces, for example exploiting the fact that a transaction could have multiple outputs, but in ethereum you can easily visualize which amount of money goes from which address to which other adress.

    Reduces the size of the block making it faster.

    Privacy is not as good in ETH where it is easier traceable.

Transactions are faster and cheaper.

In an account model is no possibility to camouflage transactions, every transaction goes directly from one acc to another acc.

  1. The account model doesn’t require much space as the UTXO’s model because instead of having UTXO’s, the system just gets updated and it is more efficient, allowing more storage for transactions.
  2. The account model is not as good for privacy as we can see who is sending the money, whereas the UXTO can pay out multiple accounts, and one of them can be your own.

1)it saves space which allows for more transactions to be included in the same block
2)the anonymity is not as good bc you can track all address that sent and received vs UTXOs can have multiple accounts it pays to

  1. The benefit is that more transactions can be put into less MB than in the UTXO model.

2 You can not send funds to yourself in the account modal, But UTXO model allows you to send funds to yourself and other parties simultaneously.

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

It reduces transactions size which means more space in a block for more transactions and lower fees per transaction (less bytes).

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

A transaction in UTXO model can have multiple outputs, making it harder to know to who belongs each output, meanwhile in account model, every transaction is only a substraction from one account and an addition to the second account.

The ETH blockchain has all transactions yet no UTXO (Vs Account model); the code for all smart contracts and the State of all smart contracts (S1-S4) over the time durations of the contract.

It is much easier for Account model to code the balance transfers from and to whom totals the totals are Summed rather than code in BTC what each UTXO in and out and what each goes

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

The entitlement is not directly attributable to the user’s ownership OR VALUE Transfer yet for these smart contracts, the blockchain assigns ETH into existence which now drives Gas.

ETH models does provide a balance of your assigned Account yet this takes up less space to convey in code and is less private.

BTC is Transaction-based; it is more challenging to protect privacy for account-model blockchains LIKE ETH

UTXO in Bitcoin can be tracked, by its nature, / each Satoshi is non-fudgeable;

In BTC, one send the UTXO as a transfer of 9one or more allot or UTXO s in one steps, including to yourself for the necessary change, including as input the output as UTXo to yourself;

Each of BTC UTXO is traceability back to the miner that created it

As an Account model, all ETH is presented as a balance of this account

One ETH is indistinguishable from the other, as Sum only.

In ETH can send exact amounts to exact address.

Efforts for hiding account balances, transaction amounts, and linkage between senders and recipients are underway.

1: by requiring less space the account model allows to have more transactions per block which in turns accelerates the network and reduces fees.
2: the account model is not as great for privacy because each transactions are only one to one. so you know which source went to which destination.

  1. Less space means smaller blocker sizes
  2. In the UTXO model you can have outputs that deliver back onto yourself and to someone else all in the same output. This makes it harder to determine if the receiver(s) are another person other than yourself.
#2160
  1. since no UTXO’s take up space (bytes), all transactions are smaller (take up less space in the bocks), less fee
  2. there is less privacy because in the Tx history, you only see sender and reciever. there are no extra selftransactions which would make it hard to know how many btc are moved to sender or to yourself. in this matter we can discus that ETH is more fungible and less traceble

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Lower space requirements means that theoretically there will be a lower barrier to entry to become a node or miner, and also the running costs should be lower / performance of the nodes should be faster which will encourage more computers to join the network.

  2. How is the account model not as great as the UTXO model for privacy?
    Under the UTXO system, it is difficult to determine exactly who is receiving the currency from each transaction; The outputs from each transaction are marked for various address destinations, but the public is unaware of who owns each of the addresses. On the other hand, the account model works similarly to a bank system where it is clear how much balance is held in a specific account, as well as the inflow and outflow over time.

#2162

This makes it simpler to find a balance, and also is more efficient in its storage

UTXO’s allow for a better audit trail of the transfers of value

#2163

Great answers. It’s easy to understand. Great work. :clap:

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
By not using the UTXO model, transactions don’t need to as large. This means that smaller transactions will have smaller fees per byte and transactions could potentially go faster (in certain situations.)

2. How is the account model not as great as the UTXO model for privacy?
This account-model doesn’t allow for the sending of transactions to both a recipient and yourself in one transaction. It is easy to see which account paid another, their balances, etc.

  1. Less storage and more transactions or smart contracts per block.
  2. The account is public, all transactions can be linked to the account.
