Homework on UTXO vs Account Model

[Crazysword]

less space means faster transactions, more fungible.
the account model is as great for privacy because you cant trace it back and you cant send it back to yourself it just holds a balance.

Because you dont have to track every utxo. That saves space and reduces the size and growing of blocks.

The UTXO model implies that installments muddle what portion of an exchange is going to the beneficiary and what part is being gotten back to the sender.

1. There can be more ETH transactions and the savings in space is a huge feature.
2. The account model will show who is making the Ethereum transactions while the UTXO is a unique transaction string in the blockchain.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   The account model is a benefit because not needing much storage space enables confirmation times to be faster, in which it theoretically lowers transaction fees.
2. How is the account model not as great as the UTXO model for privacy?
   In Bitcoin’s UTXO model new addresses for each payment gets created. Furthermore, one always has to spend their entire UTXO, therefore sending money to the recipient and whatever change is left over back to oneself. In the account model the transaction that the user has sent out is recorded. It is similar to a bank account, sending from a bank account is a direct path, money from one account is being sent to a receiving account. In other words, it is known who is the sender and who is the recipient.

1. Because in Account Model you cannot trace the past transaction or where the coin originates, you will only be able to check the current balance.
2. In account model you will not be able to send money or some change to yourself so everybody can see where coin moved (to which address). While in UTXO you can make a few transactions at the same time to yourself or somebody else and yourself.

1. Faster to do a transaction
2. Account Model can track recipient’s account

[Divij_Dawar]

1. The transaction will take up lesser space and hence more transactions can fit in a block.
2. The account model isn’t good for privacy as you can track the address of who has been paid whereas in the UTXO model privacy is higher.

[UFAME]

1. Easier to express in code & text vs tracing multiple outputs for an answer
2. The account model has only updates, no output transactions. ETH is fungible vs BTC non-fungible, Each BTC is specific & traceable.

1. The account model doesn’t require as much space as the UTXO model, why is that a benefit?
It’s a benefit because it frees up resources for executing logic-based instructions as opposed to storage transaction history.

2. How is the account model not as great as the UTXO model for privacy?
Because, unlike the UTXO model, you are not able to send two transactions at once, preventing you from sending a transaction back to yourself, which makes it difficult to know which account received the value.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   It means that the block size is smaller, thus faster transaction and also lower transaction fee.

2. How is the account model not as great as the UTXO model for privacy?
   The transaction from one account to another is recorded, including the balance, whereas for UTXO model, each transaction can have multiple inputs and outputs, thus it is harder to trace where the funds go to exactly.

The UTXO model does not incorporate accounts or wallets at the protocol level. The model is based entirely on individual transactions, grouped in blocks. We can compare this to people holding certain amounts of cash.

Any space saving is an advantage. Since the entire network nodes are intended to be managed by individuals rather than data centers, the lower the data requirements, the more potential participants.

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

The account model is not so good for privacy because you can track the address of who has been paid while the UTXO model can pay out multiple accounts, one of which can be yours

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?

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

1. Full nodes are able to able to reduce costs from space savings

2. In the account model, the payee and recipient is exposed in the transaction as the fund is transferred directly from one party to the other.

[Fengzi]

1. The Account Model benefits from not using as much space by being quicker. It only tracks the balance in the wallet instead of having to track each UTXO.
2. UTXO is capable of sending BTC to another wallet and back to the individual so it is not possible to know how the BTC arrived.

[Jay_Wagner]

1.More transactions can fit into a block.

2. Account model is an A to B transaction, everyone can see where assets went and who received it. UTXOs can be multiple transactions at once and nobody knows who the addresses belong to, some can be sent back to yourself.

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

1. The smaller the packet the faster the transaction and less resources needed to conduct the transaction or the more transactions per second that can be completed.
2. Accounts are more easily traced whereas UTXO finds the first available opening to conduct the transaction providing better anonymity as it is randomized.

[ShreyPanda]

1. By not requiring as much much space, it is a benefit. Blocks can then store more transactions and operate more efficiently.

2. It cannot be tracked by its UTXO footprint. Under the account model, the balances are just being updated rather than being able to see which accounts spent what.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   Smaller block size means smaller fees.
2. How is the account model not as great as the UTXO model for privacy?
   The account model is easier to trace because it is a single transaction public on the blockchain, with the UTXO model you can have multiple addresses in one transaction

[Pedro_GM]

1. Because blocks would be smaller, thus allowing faster processing, higher scalability and an increase in the blockchain’s capacity.

2. The account model is not as great in terms of privacy because you can easily trace back the address that sent you money, as there are no outputs. In the UTXO model, you can have multiple outputs in a transaction, making it harder to know how much money was sent and to whom.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   It allows for faster blockchain validation
2. How is the account model not as great as the UTXO model for privacy?
   The account model does not have UTXO’s, which allows people to track every transaction. There is no question from where the TX came or Went because each transaction is a single action
