Homework on UTXO vs Account Model

[Emmett]

1. Because ETH is just moved directly from one account to another. There are no scattered UTXO’s to locate on the blockchain and sum together
2. Becuase you can see the direct transfer from one account to another. With bitcoin there is usually 2 outputs at least where one is the ‘change address’ this makes it a little harder to see where monies are going to in a transaction.

1. The account model benefits over the UTXO model from increased space that is available from not having to record multipl inputs & outputs of UTXO’s. This make it faster & leaves room for things like smart contracts
2. The account model simply updates account balances when TX’s are made whereas the UTXO model ( which can have multiple i/p’s & o/p’s) permits the situation where differentiation between outputs is difficult to determine. This can shield identity from reverse tracing thereby making the UTXO system MORE private than the account system. (Not easy to arrive at that summary from Ivans explanation - (sorry mate you kept me busy chasing your thoughts for a while there)

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

@almanat

maybe I misunderstood but I though it was more fungible and therefore bit more private since you cant trace origin of the the txn and blacklisted coins… combining UTXO would just corrupt the whole balance, in the eyes of the law. one would think…

The UTXO model it just makes it harder to track, there are still procedures to keep track of the funds provenance of a wallet (since the blockchain is public, there will always be a way to track any wallet funds). The Account Model is quite easy to track the provenance of a wallet/account, since you can track “from, to, quantity, hash, time” on the blockchain in a way more simple than UTXO.

Hope this gives you a clear view of the subject, keep learning! :

If you have any doubt, please let us know so we can help you!

1. Becuase they don’t use uxtos sistem, then is possible to write the in code using less bits… is in other words one imput and one output in every "transaction"always.
2. Because anyone can see exact how much money is sent in each transaction (in bitcoin you can sent part of the money back to you).

[N8ture]

1.More transactions can be processed using less block space.
2. UTXO model enables you to send a transaction to more than one address while not showing how the amounts were allocated to each one.

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?

The account model’s space efficiency compared to the UTXO model’s is beneficial because smaller file size is a compounding effect. Small file size increases rate of data transfer, decreases storage capacity time, and consequently smaller fees.

@filip

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

The privacy of the account model doesn’t grant the same anonymity as the UTXO model. This is due in part of the publicity of the account model’s transaction history. UTXO model encrypts all inputs and outputs.

1. More space could lead to slowing down.

2. In the account model could be track the address of who has been paid and where will go.

[Mroman]

1. It makes the transactions on the network faster
2. You can not check past transactions

[Ziheng]

1. This will allow more transactions to fit in a block, hence speeding up the transaction time and reducing the transaction fees.
2. For the UTXO model, one can have multiple outputs in a single transaction. Hence, it is impossible for an outsider to know which output is going to which person, and this increases one’s privacy. Whereas for the account model, when a transaction is made, it is clear that where the money is going, from a sender to a receiver.

[BryanSC]

1. The account model saves space compared to UTXO, which creates faster and more efficient transactions.

2.With the account model, your spending is more visible. You can see exactly how much was sent to which address, and you can’t send eth back to yourself.

[Benitez]

1. by taking up less space you you can make the network more efficient.
   2.You cant really be anonymous with etherium you can see transactions move from account to account.

[Pkgno1]

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

This is a benefit because it makes the Ethereum network faster as there is less data in a block and more transactions and smart contracts.

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

Because its easier to track and followw each coin with the account model.

[0xMac]

1. Less space is less energy from nodes is less expensive transactions.
2. It is easier to track one transactions with one row compared to one transactions with multiple rows. Also eg some criminal bitcoins can be banned from exchanges.

[rubio132]

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   By making Eth network faster by not needing as much data in a block and speeding up transactions since funds is going from point A to point B.

2. How is the account model not as great as the UTXO model for privacy?
   Less privacy because everyone can see transactions on the eth network. Exactly how much and location.

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

1.- Because the blocks could be lighter and can propagate much faster over the network

2.- Because each transaction could be easily identified, goes from A to B, and you can’t sent it back to yourself like in the UTXO model

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?
   the block can stay smaller like this, therefore it enables more and faster transactions.

2. How is the account model not as great as the UTXO model for privacy?
   The UTXO model can have different outputs, which makes it difficult to trace a transaction. In the account model on the other hand, the transaction moves from A to C, which can be traced much easier.So no multiple outputs.

[zinovsky]

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   Is a benefit because the blocks can include more transactions
2. How is the account model not as great as the UTXO model for privacy?
   Because in ethereum you can easily trace the transactions

[Wren]

1. The benefit is that it has better storage because it takes up less space.
2. The account model has no outputs and the transactions are seen from the outside. It is not as good a model for privacy as the UTXO.

[hamzastrife]

1. Because additional space will allow more information to be transferred across the network of nodes
2. Because you can’t send funds to yourself and is difficult to find out where your money came from, since your balances are simply updated instead of seeing how the UTXO is transferred

[Trinity]

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
   That is giving increasing transaction numbers in a block.
2. How is the account model not as great as the UTXO model for privacy?
   It is a balance that you have. And that is traceable and visible for everyone.
