Homework on UTXO vs Account Model

Ethereum 101

  1. The account model requires less space because transactions store less information.
  2. In te UTXO model you see the different UTXOs being spent but you cant see how much receives the recipient in total because some may be used to pay fees or to send back to the owner.Moreover, we can track the “coins” in bitcoin because UTXOs gives us the info of where do they come from so in reality bitcoin is not fungible.

  1. The account model is beneficial with regards to space because it enables ethereum to have more transactions per block compared to bitcoin.

  2. The account model is not ideal for privacy because its easier to see your wallet balances and you cant hide your transactions as easily.

  • transactions more fasters
  1. How is the account model not as great as the UTXO model for privacy?
  • is more transparent and readable to see whats happend, in UTXO you is more difficult to see what happend with the criptos

  1. The account model not requiring as much space is a benefit from both blockchain space and coin fungability point of view. It also means a wallet does not have to parse as much of the blockchain to acquire your balance.

  2. The account model could be considered worse on a privacy point of view because there is no discrepancy on where all the funds have gone. It is between the accounts stated in the transaction and not anyone more.

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

Blocks can contain more transactions, transactions can be faster as less size to mine and it also helps nodes require less space potentially for more transactions.

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

UTXO can send to multiple at once while not showing how the amounts were allocated to each one. Account model is not as private because each send is one to one so you can always check how the amounts were allocated to each one.

  1. its much simpler to write in code, it takes less space and is more efficient
  2. UTXO model is more private because it has many inputs and outputs and you do not know who controls the address. Ethereum updates account balances but its easier to see what account addresses the payment is going to.

  1. It is a benefit because a transaction does not have to consist of UTXO’s. This makes transactions faster and not as complex.
  2. The account model does not let an address send back to itself to disguise the funds being transacted. It is more transparent because the transaction just shows they transfer from one account to another, whether it be between 2 of your own accounts or your account and someone else.

  1. The account model makes it easier to write commands in code unlike the UTXO model which has to have numerous commands for all the transactions that happen to a wallet. For example, it is simpler to write “send 1 ETH from this wallet to that wallet” vs. “this wallet receives this much BTC from A. Then this much from B. This much from C. And then sends out ‘x’ amount to D, ‘y’ amount to E, and ‘z’ amount to F.” This condensation of transaction commands will allow more space for other things like more transactions.

  2. The ETH account model is not so good at privacy as the UTXO model on BTC because anyone can tell who exactly sent the ETH to which recipient. The UTXO model obscures this because it allows a wallet to receive multiple inputs and send out multiple outputs, making it impossible to determine who sent what to whom.

1 - Because less space would allow for more transactions, would also be cheaper.

2 - Because Ethereum only has one address per input and ouput, so you can’t send some back to yourself as a way to create more anonymity like Bitcoin.

It’s a benefit because one block can store more transactions, which means faster processing and potentially lower fees.

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

Because you cannot send multiple transactions at the same time to obfuscate your leftover balance. If someone knows a certain wallet belongs to you, they can see how much money you have and how much you’ve sent and to whom at all times.

  1. it means not as much space is taken up on the blockchain. blocks can have more transactions
  2. because it does not allow you to send funds to yourself, you do not send TXs to many outputs. there is one input and one output for every TX. very obvious where funds are going.

  1. It not taking up as much space allows for more transactions to be allowed in a single block.
  2. Fungibility is key when determining privacy.

it can only store the TX’s from our balance to an other balance and doesn’t has all the outputs and inputs of the UTXO’s
2. how is the account model not as great as the UTXO model for privacy?
you can only send to one acount money with the account model and with UTXO model you can send BTC to more than one address and even back to yourself

  1. The account model is lighter, so it is easier to run and is faster.

  2. The account model states who is the sender and who is the receiver. so there is less privacy. The UTXO model is more vague and registers several transactions as a bulk , you can send money back to yourself on the same transaction.

  2. How is the account model not as great as the UTXO model for privacy? Because you can see on the database what accounts have sent/ received money.

  1. Because you can use the added space for more TXs.
  2. the account model shows the sender and receivers balance where as the UTXO model does not.

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
Because it makes the transactions lighter -> the transactions part of the blockchain lighter to store
2. How is the account model not as great as the UTXO model for privacy?
Because with UTXOs it’s possible to send money to multiple addresses within 1 transaction which makes it easier to cover the tracks. With Ethereum, each address had an account and whenever a transaction is done we can see track it easily.

The account model doesn’t require as much space as the UTXO. It reduces block size which allows for faster tx’s.

2. How is the account model not as great as the UTXO model for privacy?
There is a lack of privacy in the account model because you can track the sender and receivers information.

Homework on UTXO vs Account Model:

  1. The account model doesn’t require much space and that is a benefit because its transaction require significantly less space including short information about numbers of users accounts.
  2. Account model is not as great for privacy because it shows to the publicity how much money exactly an account has. Also coins of this model are fungible nevertheless their origin including illegal one.
