Homework on UTXO vs Account Model

Ethereum 101

OK, I got two likes on my quote but no answa XD. Can anyone help?

  1. Saving space means that each block can include more transactions which also potentially impacts network speed.

  2. In the UTXO model, there is no specific address one can identify as “the sender” so it is more difficult to decipher who is sending and who is receiving each output/input. In the account model it is simpler, just showing one transaction between one account and another.

  1. any saving of space will be beneficial, blocks can include more transaction and faster

  2. you can easily see where money comes from and sent to. its a bit less secure

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Smaller Transactions, the file grows slower, less fee

  2. How is the account model not as great as the UTXO model for privacy?
    Account and balances are public

    Account model doesnt contain inputs and outputs transactions, thus requiring less space

  2. How is the account model not as great as the UTXO model for privacy?
    Easier to see where the money is coming from and going to. Not as secure as bitcoin.

  1. It is a benefit because it is more energy efficient. The blocks will not get filled up too fast, so it prevents lag time and high fees

  2. Because you can send the exact amount, so you don’t send yourself the change. Thus it is more obvious who received the money

  1. This allows more code to be added in each block leaving space for programs such as smart contracts without blowing up the block size.

  2. With Eth you can send exact amounts from one account to the other. This means that when checking the blockchain you can see exactly how much was sent from one account to the other. With Bitcoin UTXOs are used and can be split in a transaction and sent back to yourself making it harder to identify the sender and receiver.

  1. Less space per transaction equals more transactions that can be stored in a block. This is crucial for blockchains to have especially one with as many tokens and as big as Ethereum. The more that can fit into a block the more efficient and faster the network becomes.

  2. Because it is easier to track where money is going in an eth transaction than those that use UTXO’s. As the UTXO model allows for you to have multiple outputs in a transaction, as opposed to one, and some of which could even be you sending money back to yourself. Which adds further confusion as one from the outside cannot tell which outputs are to others or yourself.

  1. Account model takes less space on the blockchain and more transactions could be stored in one block. This allows space for smartcontracts and more code to be stored in block in general.

  2. Because externally it is easier to track where money is flowing with Account model. With UTXOs in Bitcoin it is from external point of view harder to find where this amount coming from and where it is heading in connection to the owner of the funds.

  1. The account model in Ethereum has more efficient memory usage. Storing a single account balance saves memory compared to storing several UTXOs that comprise a user’s total balance. Transactions in the account model are also smaller in size because they only specify the sender, receiver, the transfer amount, and a single digital signature.

  2. The UTXO model makes it harder to link transactions, whereas the account model is more fungible. When change addresses are consequently used in the UTXO model, it makes tracking the owner of coins harder compared to the account model.

  1. It is simpler transactions are smaller. That save space in the blocks and allows for faster transactions.

  2. Transactions are easier tot follow from the outside because there are just straight transactions and no multiple transactions

  1. You have smaller transactions, with a simpler model to express in code. “move money from account A to account B”, making updates on the blockchain.

  2. From the outside you can see how much money was sent and for which address.

More information can be added to Ethereum blocks because less space is used for inputs and outputs.

You cannot send money back to yourself in the same transaction. Account balances merely change for each address on the exchange. You can see who sent what to who more easily.

Yes, if you want to cloak your activities, you receive your change at a different address than the one you sent from. Some blockchains, such as Cardano, do this automatically now. I personally think it’s annoying to have endless addresses, as it forced me to keep my own accounting books. The apis on the crypto tax services are apparently not ready to handle this.

  1. By updating accounts rather than calculating endless UTXOs, less block space is required per transaction, and the network is more efficient because more of these simpler transactions can fit in a block. ETH fees would be absolutely insane under the UTXO model.

  2. Since the account model does not allow for receiving UTXO change (and all the ways you can cloak your activities through that mechanism) people can look at the blockchain data and easily see which wallets have what.

  1. less space means faster t’s
  2. it’s easy to see where the coins are going, and when you try to send to yourself

  1. Less space required means faster transactions and lower fees.

  2. Because in the account model it is more difficult to mask distribution of assets to your own accounts. In the UTXO model you can have several outputs and nobody knows if one or more of them belong to you, whereas in the account model you just have one sender and one recipient, who can either be you or not, which makes it easier to keep track of the money flow.

  1. It’s a benefit because with less space it allows for more transactions to be stored into the block.

  2. With the ETH account model structure. It can allow the transactions to be seen from where they’ve been sent to & whom. It doesn’t allow for mult- outputs including yourself for privacy.

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

  • The requirement for hard storage is reduced;
  • The account balance can be read quickly;
  • A smaller tx means that it executes faster - overall;

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

  • in bitcoin utxo(s) can be sent back to yourself hiding balance ownership;
  • there is no transaction tracking in etherium: you can’t send back to yourself and account balances are public.

  1. The block can include more transactions within it, thus increasing the overall efficiency.

  2. The account model can be easily verified where the money comes and goes to. UTXOs makes it difficult for users to know which where that money goes to because of the possible numerous outputs.
