Homework on UTXOs vs Account Model - Answers
- The account model doesn’t require much space as the UTXO model, why is that a benefit?
This is because every transaction is smaller in size for the account model. This also enables a larger number to be fitted into a block for a higher transaction speed.
- How is the account model not as great as the UTXO model for privacy?
Ethereum’s account model
○ Does not allow multiple inputs and outputs in the same way that Bitcoin allows for them
○ Does not allow for money/assets to be transferred to different wallet addresses, including your own, in the same transaction (like on Bitcoin).
○ This reduces privacy as you can always tell which account the assets came from and went to in any transaction, rather than in the case of Bitcoin where the UTXOs can be sent to a change wallet so ownership of assets is obfuscated.
