Homework on UTXO vs Account Model

  1. It doesnt take that much space and therefore a larger capacity is possible. One block can therefore store more transactions.
  2. The account model has less privacy because you dont send the coin urself

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

Creates much simpler transactions that. take less space in a block, so more transactions can be processed at the same time

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

You can see exactly how much money is being sent, and to which address, in comparison to Bitcoin where you can have multiple inputs and outputs including money being sent back to you

  1. More transactions will fit in one block, so this makes it faster and more scalable.

  2. You can easily see who is sending what and to who. 1 eth = 1 eth. When you send 1 Bitcoin to a person it will have different outputs, so you’ll not know how much you sent to who and much change went back to you.

  1. The less space it takes up, the lower the processing power is required between each transaction.
  2. In the account model you can see exactly where the transaction is going and to whom and with the UTXO model there might be several inputs and outputs to include funds coming back to yourself.

  1. the data for the transaction is estimated on the available assets in the account model.
  2. no anonimoty, transactions can be traced. with UTXO not possible.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    As the Ethereum blockchain already needs more space due to the smart contracts and their states being saved on the blockchain, it makes sense to limit the space used where possible.

  • How is the account model not as great as the UTXO model for privacy?
    You can not send coins back to yourself, account balances are public. Easier to visually follow as coins go from one account to another

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

Transaction processing is faster because the transaction data smaller. It’s more fungible than bitcoin as it only stores transactions and amounts and is not keeping track of the entire coin history.

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

You can’t send coins back to yourself through an anonymous address.

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?
    More space in a blockchain enable more transactions as well as more complex contracts
  2. How is the account model not as great as the UTXO model for privacy?
    We can not trace totally the entire chain of transactions for one precise etherium. It makes etherium a little bit more fungible. Though, the fact that the transaction doesn’t allow to be split and having a part of the utxo back to our Bitcoin account on BTC, it’s impossible to trace which part of the Bitcoin sent is back to the sender.

  1. The account model doesn’t require space because any space saving would be of benefits to the nodes that are operated by individuals.

2.because in the account model you cannot send funds to different account and the transactions are not easily traceable.

  1. Smaller transactions mean saved space, making everything run faster which means smaller fees (per byte).

  2. You can’t obfuscate your intentions with dummy transactions, anyone can view each transaction from the outside and all transactions are bound to an account. With UTXO, users can use a new address for each transaction.

  1. Makes the network more scalable
  2. It’s not possible to confuse someone looking at the transaction by sending funds to yourself

You can fit more transactions into a block and that makes it more scaleable, faster and has lower requirements for the storage capabilities on nodes.

You can’t track the origin of the ETH on the same level as with BTC UTXOs. UTXO you can track back to when it was first mined and you can see the entire road, whilst with ETH you see only 1 step back and forward. Meaning that you see who sent and where, but you can’t see the path of that particular ETH. With ETH you can also send exact amounts, so you don’t have multiple outputs that are difficult to distinguish.

  1. It serves as a benefir because it doesn’t store up space and makes these spaces available to make transactions faster

  1. Account model dose not store all the utxo’s wich makes the blocks smaller and faster

2.cause utxo follow the coin from the beginning when its miner through all transactions up to current time( wich would be now)

quicker and takes less space so more efficient

How is the account model not as great as the UTXO model for privacy?
in the account model you see exactly where money it going, in UTXO you can send multiple transactions to hide which is your account

  1. Smaller transactions, smaller fees, node grows slower.
  2. Because UTXO can have multiple transactions, to help protect identities.

  1. If the account model uses less space per transaction, it could potentially have more transactions in the same blockspace (1mB in BTC example). This makes it more scalable, because when more transactions can be placed in a block it’s less likely to have a “full mempool” (not sure what the naming of this is at etherium), which means the time a transaction is unconfirmed en the cost of a transaction will potentially be lower then using the UTXO model.
  2. You are not allowed to send funds to multiple parties in one transaction. For example when you send some btc to a certain adress the change of the used UTXO’s will be sent to your own adress, but from the outside it’s impossible to determine which of the transactions is going where.

  1. It is beneficial because smaller blocks are faster. Also more storage is available for more transactions to be stored. It is time and storage efficient.
  2. With the account model, it is one connection from sender to receiver. It’s easier to than it would be to track a UTXO because UTXOs can be sent to multiple accounts which makes it harder to follow.

1 The account model not requiring much space as the UTXO model, is a benefit because the network is more efficient in terms of bandwidth utilisation and more nodes and participation is possible hence more blocks, more transactions, more adoption.

2 The account model is not as great as the UTXO model for privacy because it’s easier to trace TX since you can only add to or remove from the balance. This reduces the anonymous nature of bitcoin which makes it possible to send multiple transactions to multiple people including yourself at the same time it more difficult to trace unlike ETH.

  1. It is a benefit because it takes less space. It was a problem for btc the size of tx, and that s why segwit happened.
  2. Because on Eth you have balance, always an updated account. The sender sends directly to recipient.
