Homework on UTXO vs Account Model

Ethereum 101

  1. Benefits are faster transactions, less data being sent since only one tx can be sent and no need to add UTXOs in wallet.
  2. Account model doesn’t have the traceability of transactions making ETH fungible.

Since the account model doesnt require the same storage capacity as the UTXOo does, it supports faster network speeds and higher scalability.

UTXO model allows for you to send multiple outputs at once, which could include yourself once or even multiple times. The account model is only wallet to wallet and is trackable through account balances.

  1. less space in the block, fast transaction, low fee
  2. In account model an tx has one input and one output, is easy traceable, instead in the UTXO model the tx can have multiple input and output, that give you a ability to sent to yourself. This offer more privacy .

  1. 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. You can’t send funds to your self and funds go from 1 account to other account. It’s easier to visually follow.

  1. Less space and nodes with less burden.More transactions, less memory.
  2. Because you can track address of recipient and how much money was sent.

  1. It’s quicker to execute because it’s not taking as much space as BTC transaction
  2. Easier to track the transactions as transactions in the ETH network are not mixed

  1. The account model doesn’t require much space as the UTXO model. The benefit is that you have more transactions in a block.
  2. The account model is not as great as the UTXO model for privacy because you can track the address of who is sent the money and also the receiver of funds.

  1. The account model has smaller transactions, which allows for greater capacity and makes the process faster and fees smaller.
  2. The account model is not as private as the UTXO model, as tracking addresses is very easy. The UTXO model allows for multiple payout addresses including ones to yourself which can be much more difficult to trace.

  1. Less space in the block
  2. Because we can see the source of the money, where it comes from (address).

  1. Lower transaction fees , more transactions per block, faster.
  2. Transactions and balance are public.

  1. Taking less space in the block

  2. The transaction has one input and one output and you can track the sender and the receiver

  1. Smaller transactions results in a lower size of the transaction (in bytes). A block on the blockchain just have a limeted size/ volume of transactions it can take (1MB for Bitcoin. Therefore the ETH miners/ nodes can put more transactions in a block in comparison to Bitcoin which makes it finally cheaper and faster.

  2. In the Account Model of ETH you have a kind of Balance but no UTXOs. In ETH you simply update the balance and it is easy to track wehre the transaction comes from and where it goes. The UTX modell in Bitcoin allows you to send Outputs to several adresses like your own.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    because it simply says to move X eth from A to B and updates the balances. Instead btc tx has to take into consideration all input (UTXO) and then the outputs

  2. How is the account model not as great as the UTXO model for privacy?
    because with btc if utxo is not big enough for a payment they will be used two or more utxo and the change will go back to me. Or anyway I can send in the same tx btc to someone else and also to me at the same time. Now, there is no way to tell which part of the tx went back to me and which to the other person.
    Instead in eth a tx updates the balances and so the tx either goes to somebody else or it goes to me. No mix situation.

    Transactions take up less space, which means you can put more transactions in a block, thus making them faster and cheaper.

  2. How is the account model not as great as the UTXO model for privacy?
    You can easily see all the balances and follow all transactions which are more simple than in the UXTO model with bunch of inputs and outputs. With the account model you can’t send the change back to you with the same transaction like you can with the UTXO model.

  1. Less space contributes to lower data requirements, which enables more nodes to participate on the network, and therefore greater network security. Account model also affords more efficient data storage with more transactions per block and more faster processing times.

  2. The UTXO model used in Bitcoin allows for multiple outputs in a given transaction, any number of which might be controlled by the sender. This enables greater anonymity as it can become difficult to decipher which address was the intended recipient and which address(es) might be merely a change wallet owned by the sender designated as a means of generating greater privacy. Total anonymity is less plausible on the Ethereum network, as the account model offers a simpler flow of transaction. There is no notion of UTXO’s issuing between multiple inputs and outputs. There is simply a sending address and a receiving address, which is transparent and traceable. Each transaction is displayed publicly on the blockchain, detailing how much was sent and to whom.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Everything is synchronized to all nodes (you would like to avoid replication as limited as possible)
  • How is the account model not as great as the UTXO model for privacy?
    If you send one transaction that is split in two amounts/output (and one of them is from yourself) it is easier to see which addresses are behind it. In Bitcoin is a change wallet used what is giving more privacy.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
a. You can fit more transactions into a block and because of that have a faster network propagation as well as lower transactions fees compared to the Bitcoin network
2. How is the account model not as great as the UTXO model for privacy?
a. With the UTXO model it’s easer to obfuscate the flow of money by, for example, creating a transaction with multiple outputs, where one could send a certain amount of the total output to someone else, while the remainder flows back to an unknown BTC address held by the sender

Less space equals less strain on the network

Because as an outside person can see the recipient of ETH and the senders address unlike with UTXOS where there can be multiple recipients making it harder to distinguish who is who.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Takes up less space on the block. It just records the amount of ETH and not all the unspent transactions (UTXO’s).

  2. How is the account model not as great as the UTXO model for privacy?
    Because it is fungible. The transit of coins can easily be tracked from account to account since there are not a multitude of transactions to follow.
