Homework on UTXO vs Account Model

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    THe block size is kept low so transaction fees (gas) can be kept lower, the transmission of blocks could be faster as well so in theory less stale blocks
  2. How is the account model not as great as the UTXO model for privacy?
    You can check the balance of the account on the blockchain and the obfuscation of your intention by sending back UTXOs to yourself is not possible

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? The benefit of not requiring much space in the account model is that it is more efficient to determine the balance of an account as you only have to retrieve one data record. It it not necessary to revisit every transaction involving that account.

  2. How is the account model not as great as the UTXO model for privacy? The account model clearly shows what was spent and to whom the asset was sent. The UTXO model, on the other hand, does not reveal the owner of the wallets involved in the transaction.

  1. The blockchain here is smaller and dont have to add all the transactions to get the balance.
  2. We have the from and to addresses for the whole transaction.

   You are not keeping track or record of transactions on the chain, only ballances. 

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

   In the UTXO no one can tell what wallet belongs to who, and you can send multiple translations at once. You can tell how much money was sent and to what wallet. You can only do one translation at a time.

Benefits of the Account Model
The account model requires less space than the UTXO model because it only updates balances in accounts, rather than storing multiple transaction outputs. This reduces blockchain size, leading to faster transactions and lower storage needs.

Privacy Comparison
The account model is less private because transactions update account balances directly, making it easier to trace the flow of funds. The UTXO model, by creating new outputs for each transaction, makes tracing the flow of funds more complex and enhances privacy.

Transactions in Ethereum take up less space because the account model updates balances directly without needing to track individual UTXOs. This is beneficial because it reduces the amount of data stored on the blockchain, making it more efficient.

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

The UTXO model enhances privacy by breaking transactions into multiple outputs, making it harder to trace the ownership of specific coins. In contrast, the account model updates balances directly, making transactions easier to trace and reducing privacy.
