Homework on UTXO vs Account Model

Ethereum 101

  1. Scalability is increased with the account model, because less storage is used compared to the UTXO model.
  2. The account model reduces privacy because transactions can only go from one account to the other, whereas the UTXO model transactions can send funds to multiple accounts at once, one of which can be your own account.

  1. Less congestion on the network that would benefit all the code running for all the smart contracts.

  2. Anyone can see exactly how much you sent to each address unlike a UTXO which usually has more than one output.

  1. Less space for the account model means that more transactions and smart contracts can be fit onto the block, this is a reason why smart contracts are executable on the ethereum network.
  2. The account model is easier to track movement of ether from one account to another, where as with UTXO’s could be going to any number of addresses and it can be difficult to trace which address belongs to which person/business/company.

1.) It is a benefit because it allows for more transactions to be stored in a block and processing this model doesn’t require as much computing power or storage.

2.) Because where transfers are sent as well as from where they were sent is plainly visible.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Cheaper transactions, total blockchain data grows slower.

  2. How is the account model not as great as the UTXO model for privacy?
    Less easy to obfuscate the flow of tokens, although it does not really matter with automated transaction tracing.

The account model doesn’t require much space as the UTXO model, why is that a benefit?
In the account model, balances are stored as a global state of accounts, kept by each node, and updated with every block. This is similar to a database.Account-based systems offer storage benefits because the account’s state and transactions are smaller. More efficient memory usage, only specify the sender, receiver, the transfer amount, and a single digital signature.
This also means that it’s faster to get new nodes online in a system running the account model because less data is needed to get them in synch.

How is the account model not as great as the UTXO model for privacy?
The UTXO model has privacy more than account model because it has multiple inputs and outputs in the transaction history and hard to track address is from who send or receive it (I can sent money to someone and sent money back to myself.It hard to tell which output go to me or which output go to someone else) while account model shows clearly that you sent 1 ETH from A to B in the balance transaction.

1- Will probably be better for smaller blocks and faster transactions, for scalability
2- It goes from one to one, you can track who sent the money. In UTXO, you can have multiple outputs which is harder to track.

  1. The account model requires less space than the UTXO model is better for block time, more transactions in blocks, as well as the ability to process multiple Ethereum tokens, and store the balance of all transactions of addresses.

  2. The account model is easier to track ethereum transactions from to address to address. The UTXO model allows for a single sender to send bitcoin to more than one address in the same transaction, allowing for the potential of more privacy.

  • it will allow us to include more tx in the block, and faster processing.
  1. How is the account model not as great as the UTXO model for privacy?
  • because we can’t send tx to ‘anonymous’ address. Tx in Ethereum is done from address to address.

1.It reduce block size, and solve the problem of full block like problem in btc network, as stated low block size can be propagated fast.
2. Traceable.

  1. Because the account is just updated after the transaction, +1/-1. There is no inputs & outputs. You just update numbers in the database. In code only: “move x from A to B”
  2. From outside, you can see exactly how much money you sent to which account. In bitcoin, UTXOs make it complicated to view from outside.

  1. it is making it more simple and fungible…

  2. without having utxo,you are not able to split transaction or send money back to you ,so it making it easier to trace and reduces privacy

  1. the fact that an account model doesn’t require as much space as the UTXO model is a benefit, because the transactions will take far less time to process, which increases the execution speed.

  2. The account model is not as great as the UTXO model for privacy, because transactions are from one account to another account. It does not handle multiple outputs , nor payments to oneself.

  1. It reduces block size and saves space which is more efficient. It would make for smaller, easier transferable blocks and faster processing.

  2. With Ethereum you can see transparency of the transaction, with UTXO you can have several outputs at the same time and can have hidden identity.

  • saving space means more transactions in a block and could increase the speed and scalability.
  1. How is the account model not as great as the UTXO model for privacy?
  • because you are just moving funds from A to B, you are not sending funds and sending back to yourself at the same time (change) which would make the transaction undistinguishable from the other.

More efficient, possibly fewer transaction fees.

Account model is easier to track.

  1. Because the block stores more transactions and utilizes the space more efficiently by processing more blocks.

  2. The account model is not as secure as the UTXOs when it comes to privacy.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? It leaves more space for transactions to flow through the blockchain.
  2. How is the account model not as great as the UTXO model for privacy?
    The account model increases transparency to where you can see who’s sending and receiving money.

There is more space to run smart contracts and put your hashing power towards such instead of having to include UTXOs as well.

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

The account model doesn’t give much privacy as the UTXO model.

  1. Much more data can be saved.
  • It is faster to get new nodes because less data is needed to synchronize them.
  1. The account model implicitly encourages address reuse and thus makes ir easy to create a transaction history for a single user; in this way the transactions of a account are evidenced.
