The account model doesn’t require much space as the UTXO model, why is that a benefit?
It is easy to express in code and text to move ETH from one account to another.
Bitcoin can have a number of inputed UTXOs and then all of those have to get outputed
to another account.
How is the account model not as great as the UTXO model for privacy?
The UTXO model can send a Tx to more than one node. There is no way
to tell which output goes to me and which output goes to the recipient.
This model gives more privacy.
The account model updates accounts by adding and subtracting numbers due to the
transactions. There are not any UTXOs. It is less private because there is not
a way to send money back to the owner of the account initiating the transaction.
Outside nodes can see how much money you sent and to what address.
