Homework on UTXO vs Account Model

Ethereum 101
#1605
  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? Transactions are smaller making it faster and needs less storage
  2. How is the account model not as great as the UTXO model for privacy? You can see which account paid who. You cannot hide your transactions by sending back money to yourself. It is harder to track as you have to check for UTXO to see when the money is originating from

Less space transactions take more of them can fit into one block leading to decreased fees and better speed.

In the account model you cannot have multiple outputs that leads to better privacy.

Gracias por la respuesta Carlos!!! He podido dar luz a UTXO :blush: :dizzy:

  1. Uses less block space = less congestion.
  2. When using UTXO’s you can have 2 or more outputs and you can’t tell if you are sending yourself funds simultaneously sending funds to another person.

  1. Any sort of space savings is a benefit because if less space is needed the costs go down and more transactions are allowed.

  2. You can’t send funds to yourself while with a UTXO model it groups the unspent amount than verifies if you can send it or not.

    This allows for more transactions and faster transactions.

    The Ethereum account model has no way to send a transaction to yourself, as payments are exact. Addresses, balances, and transaction tracking are very easy to follow.

  2. You can see where the funds go from account to the other.

  1. Smaller block overhead which equates to faster processing. Fees are smaller too.
  2. The UTXO model can pay out multiple accounts including yourself and
    the accounts are publicly visable to everyone.

  1. The account model doesn’t use up as much space as the UTXO model because there aren’t any Inputs and Outputs. Ethereum txs are simply deducting the quantity of tokens being sent from account A’s wallet and adding them to the recipient’s account B’s wallet.

  2. The account model isn’t as private at the UTXO model because it is very clear how much money is being sent to which accounts, where as in bitcoin it’s hard to distinguish where the UTXO’s are going since UTXOs can be sent to multiple wallets in one tx, including send UTXOs back to the sender.

  1. Each transaction updates accounts. So when ETH is sent the EVM adjusts the account balance in the blockchain rather than using UTXOs. It leaves more room for the more complete instructions for the EVM to implement. Transaction speed increases.
  2. You can trace where a set of transaction came from by using UTXOs, the account model does not keep track of each single output.

  1. The reduced space usage of the account model means that a block with many transactions in it is smaller in size and although Ethereum blocks a limited by total gas limit rather than bytes a smaller block is quicker and easier to transmit over a network.

  2. The account model is less good for privacy as any given transaction shows the recipients of the transaction with no possibility or concept equivalent to the change address in Bitcoin. In a transaction sending 4 ETH for example, ALL of that ETH must have left the source wallet, with Bitcoin one or more of the outputs could be going back to the source wallet. As such more can be deduced from Ethereum transactions as to the true flow of currency.

You store more transactions in a block because transactions are smaller. This also means smaller transaction fees.

2. How is the account model not as great as the UTXO model for privacy?
The account model doesn’t allow you to send to multiple addresses and including yourself.
A transaction is only sent to one address at an exact amount. It’s easy to follow where the funds are going and the account balances are public.
With UTXO you can send to multiple addresses including back to yourself. It’s harder to track where the funds are going. You have more anonyminity.

  1. Transactions are easier to represent as a code.
  2. Because we can not distinguish coins. We can see only the balance of the wallet not inputs and outputs as it is in BTC.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? add more transactions to the block, more efficient, smaller fees
  2. How is the account model not as great as the UTXO model for privacy? You can view how much someone spends and what address receives it.

  1. Account model requires less space than a UTXO model. This is beneficial because it allows for fast transactions due to a smaller block size. Node file size is not as big as with BTC/UTXO. Resulting in less fees (on paper).

  2. Account model isn’t as strong as BTC for privacy. It’s easier to track direct transactions as opposed to UTXO’s. On Ethereum the recipient address can be tracked. Whereas on BTC it can be obfuscated by making multiple UTXO’s in one transaction.

1.The reason that is a benefit is because it makes the transactions take up less space, so it makes more room for other things like the smart contract code. It means there is less space needed for the transactions. This means you can fit more transactions and more things in general per block

2.The reason that this model is not as private is because you can not have multiple inputs and outputs like with the UTXO model. You only have the balance which is changed when you send or receive a transaction. So you can not do a single transaction and send funds to another address and at the same time send funds to your own address like with Bitcoins UTXO model.

  1. Smaller transactions making them easier to code, text, and move, and takes less space (more efficient)
  2. Account model is simple account to account transaction (one address to another leaving) and lacks UTXO, has no complicated outputs

  1. In computer science is every space you can save, especially in the internet, is a benefit!
  2. Funds are send from one account to another.It works like a book keeping method.

1- Because we can fit more transactions in the blocks.
2- Because its easier to visually follow the funs and also funds cant be send back to yourself.

  1. The account model uses up less space, creating faster transaction speeds and capacity for storage.

  2. The account model shows the balance of an address, including the sender and recipient. While a UTXO can send multiple address in one transaction. Making it difficult to decipher how many and to whom a transaction has been sent.
