Homework on UTXO vs Account Model

Ethereum 101
#3731

  1. It frees up space for smart contract information. Alternatively, each block can contain more movements of money.

  2. It’s easier to connect an account to an IP address and find out who owns it.

  1. Less space meaning faster network with more transaction per second.

  2. How is the account model not as great as the UTXO model for privacy?
    If I am not wrong, the UTXO allow to send to multiple addresses in the same transaction so it can cover exact amount sent to which address.

Late night studying…

  1. On the Ethereum network you have a balance instead of UTXO model and therefore takes up less space on the blockchain.
  2. It is less private in that balances are there for everyone to see.

  • The advantage lies in the option to include more transactions into a block along with the smart contract byte code.

  • BTC keeps record on the movement of every UTXO from its beginning. However, as you can send money back to yourself along with money you send to other members in one transaction, it is harder to figure out how many coins you really control. With Ethereum, every account is completely transparent in terms of the balance.

    Lower fees, less scalability issues

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

On the blockchain storage space incurs a cost. So more space for a transaction or for storing state means the transactions fees are grater, and over time state storage along can balloon up to massive storage sizes for the blockchain. Larger size would probably mean the TPS will be reduced, And this could also lead to scalability issues as well.

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

Account model means that your address would actually have a balance value that is stored and can be read easily. In UTXO, the balance of an address is always derived from different UTXOs. Though everything on the blockchain is public, this requires more work to see the actual balance of an address. And in the UTXO model, being able to send transactions to multiple addresses at the same time makes it harder to identify each transaction individually.

This enables many more transactions per block in comparison to the Bitcoin blockchain.

The account model displays both where the money comes from and where it is going, as in one account to another single account. Therefor it is not as private as the UTXO model where a transaction can have multiple outputs or accounts.

    Less space requirements means more Transactions on a Block, which results in faster turn times and less expensive transaction fees.

  2. How is the account model not as great as the UTXO model for privacy?
    Unlike in UTXOs where you can send money back to yourself, the Account Model allows you to send an exact amount to another person. So from the outside, when somebody is viewing the Ethereum Blockchain, you can see exactly how much $$$ was sent, who sent the money, and to which address. And the receiving address is EITHER somebody else’s address OR it’s your address.
    In UTXO, your account balance is not written on the Blockchain (your Wallet will determine your account balance). But, the Account Model shows your Account Balance.

  1. Tracking an account balance versus tracking multiple UXTO’s requires much less space and makes Etherium more fungible as all that is required is moving a coin from one ledger to another and updating both ledgers… ie no tracking necessitated

  2. This account model is not as private as the UTXO model as everyone can see from where to where a coin goes; whereas in the UXTO model one coin can got o multiple places (multiple UXTO’s) and no once can tell if any of the UXTO;s went back to the sender.

    *Every transaction is smaller, fees will be smaller, each block will grow more slowly, as there is less data.
  2. How is the account model not as great as the UTXO model for privacy?
  • Account codes and balances are public knowledge. You can’t make anonymous dummy tx’s back to yourself as in Bitcoin.

1.) lower space means there is more space for transactions in the block.

2.) at the account model there i had a transaction from A to B and by the UTXO model i had a lot inputs and a lot outputs and the outputs can be my adress or another.

It will take up less space in the block

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

It shows clearly the transaction from account A to B. Can not send money back to you.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?UTXO models require a lot more space/data for each transaction, requiring the info for each UTXO input and each output, whereas the account model transactions only require a simple statement of data (i.e. send 1ETH from A to B)

  2. How is the account model not as great as the UTXO model for privacy?
    The UTXO model allows transactions to come back to your own wallet, without anyone knowing how much went from your output back to your wallet. The account model would require you to own 2 or more wallets in order to “hide” or privatize your transaction.

1.
A transaction in eth don’t have input and output like UTXO, so it takes less space/storage and that means you can store more transactions in a block.

2
The Privacy is less with the eth transaction model, you can track a transaction exactly from what account send to what account. and eth is a fungible token, that means 1eth is always equal to 1eth, same value, not like the bitcoin where you can track every utxo and see where the btc is coming from and therefor the value can differentiate.

  1. It allows for more transaction throughput because each transaction requires less space in a block
  2. Transactions go from one address directly to another which is documented on the blockchain. Transactions cannot split into multiple destinations or partiality back to yourself. This is arty first easier to follow.

  1. The benefit lays in less costs to make a transaction. Every bit of space in a Block costs money to be added to the Blockchain, because of the Proof Of Work system. Also the space for every Block is limited.
  2. In Bitcoin you can make a transaction and send money to somebody( or several recipients) and in the same transaction send money back to you, from the outside nobody can say which amount went to yourself or to the other person (s).

Smaller transactions mean they’re quicker and faster. This also means more transactions can be store in a block.

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

Because you can see where the transactions are going to and from as it is the simple transfer of 1 Ethereum on the account. The UTXO model allows for multiple inputs/outputs in a transaction which obfuscates the transaction making it more private.

  1. the space savings are beneficial as the transactions take up less space in a block, Allowing for more transactions to fit per block.

2, the account model is worse for privacy as you cannot hide transactions by sending UTXO’s back to yourself

Make Ethereums blocks simpler and -I’m assuming- allows for more Ethereum to be transacted per block.

2. How is the account model not as great as the UTXO model for privacy?
With the UTXO model, all UTXOs linked to the private key must be spent each transaction. This means with all addresses hashed the reader cannot distinguish between the sender and the receiver and therefore can’t determine where each transaction is going.
The account model however just sends Ethereum from one account to another and is easily traceable.
