1- The account model doesn’t require much space as UTXO model. This is a benefit because it means that all transactions will have a smaller Byte size allowing for more transaction in a block.
2- The account model is not so great for privacy because you can see exactly who sends and who receives as the model just subtracts from one account and adds to the other. You cannot send to yourself unless you control the other account.
The account model used by Ethereum is fungible, meaning there is no way to distinguish between funds. 1 ETH = 1 ETH
The UTXO model is more private because you can send to multiple addresses including yourself within the same transaction.
The UTXO model used by Bitcoin is non-fungible, each coin can be traced all the way back to it’s origin. If a coin is was used in a bad way its use will be tainted. 1 BTC /= 1 BTC

1.Compare to Utxos mode, Ethereum account model is simpler, save more space and its token more fungible. Since the tokens can’t be trace individually thus it can’t be blacklisted and create unequal value.
- Ethereum account is similar to a bank account where one address record all income and outgoings of that account. The UTXOs are spendable only once and new UTXOs can be assigned to new addresses so that its harder to trace the owner of the fund.

- That is beneficial because it lowers the size of the blocks, allowing space for smart contracts.
- Because in the UTXO model, there’s no way to tell which of the outputs is the one that comes back to me. However, you have less ability to track the movement of each coin, making them more fungible.

The benefit of the account model is two fold one on space/data saving the other is the maintaining the value of the crypto currency or token, being an account this enables transactions like a bank also so individuals can know who it is being sent to and from who.
UTXO model provides a level of anonymity because it uses the crypto graphic public address to note as to where the transaction is coming from and to which address it is going too and then this gives an element of traceability but still anonymity, With an account the transactions start at the account and end at someone else’s account so transactions and address’s are easier to know and thus who the owner/sender is.

It increases space efficiency blockchain - it is possible to store more transactions in one block.

Because you cannot use a change wallet and send the money back to yourself in the same transaction as you are sending to someone else. On top of that in the account model all account balances are visible on the blockchain whereas in UTXO model to obtain the current account balance you need to sum all the available UTXOs for a given address.

- Because it leads to smaller transactions and their bigger amount per block therefore smaller fees and slower growth of node size.
- By usage of UTXOs there is possibility of sending some fund to oneself and someone else. In that case It is hard to tell specify destination of particular UTXOs. Account model is much more straightforward so it’s harder to maintain privacy.

1). The account model does not require much space as the UTXO model, why is that a benefit?
A) because we just have the transaction to (update the balance; send from A to B). the UTXO model need to check all the UTXO’S that you can spend. which requires more capacity. more space for smart contract. 
2). How is the account model not as great as the UTXO model for privacy?
A). It is much more transparent and simpler than UTXO, due to only having the sender and recipient visible. you can see that Ivan sent Filip pocket money for the weekend which increased his balance and decreased Ivan’s with the same amount. a crystal-clear transaction with little computation involved and much less capacity needed. another benefit with Ethereum is it is less likely to become dragged into the murky waters of money laundering due to its transparency.

-Less space means more efficiency and lower overhead. Since each transaction takes less space, you can fit more transactions into a single block. - How is the account model not as great as the UTXO model for privacy?
-The account model gives complete transparency of all inflows and outflows to and from your wallet address. And you can’t send Ethereum back to yourself the way you can with Bitcoin.

- it’s simpler and allows for more transactions at a faster rate.
- it’s less private you can who sends what to who and you can’t track where the coins came from unlike the UTXO model which allows you to trace back where the coin came from since mined. You can only send to one recipient.

Q: The account model doesn’t require much space as the UTXO model, why is that a benefit?
A: It frees up space on the blocks for smart contracts and transactions. In other words, there is more storage capacity on blocks.
Q: How is the account model not as great as the UTXO model for privacy?
A:The UTXO model has multiple outputs for each transaction. Therefore, when I make a transaction, it is hard for you to know how much Bitcoin I sent to another person vs. how much I sent to myself. With the account model (Ethereum), there is only one output for each transaction. Therefore you know exactly how much ETH I sent to a particular address.

Less space on the account model means more space to store transactions and faster processing.

In the account model, you can track the transaction and you see the balance. In the UTXO, it is harder to track transactions and there is no balance. Just UTXO.

Both models achieve the same goal of keeping track of account balances in a consensus system. The benefits of the UTXO Model are: Scalability — Since it is possible to process multiple UTXOs at the same time, it enables parallel transactions and encourages scalability innovation - How is the account model not as great as the UTXO model for privacy?
The account model is not as great as the UTXO model for privacy because there are no outputs. Each transaction can be seen from the outside, how much was sent and to whom.

It’s because the account model don’t need to store the information of the inputs and outputs which are required in bitcoin blockchain as a way to track each coin. So it has less information stored in the transaction. The less the space it requires, the more transactions can be done in a period of time

In account model, if someone wants to send its token to somebody’s address. There are only 2 addresses that are in interaction and people are able to distinguish which is sender and which is receiver. In UTXOs, most of the time, one of the outputs of a transaction is sent back to the sender and there’s no possibility of determining which output is to sender, and which output to receiver.

- require Less space = more transaction with the same amount of memory comparing with UTXO, the network require more transactions to be crowed. So much simpler to follow
- Because it is simpler than UTXO, there a less steps to follow to check the which address made transactions to a certain one. All in one bulk order, instead in UTXO, it is so much hard to see, where a part of the BTC in transaction could be from somewhere else, gathering of UTXOs

It is space saving so it allows more space for transactions in less time. -

ETH is fungible and has less privacy. UTXO can send 1 transaction to multiple addresses and yourself making it harder to trace and identify. Where Account simply sends from one account to another.
