Homework on UTXO vs Account Model

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? Smaller block size, low cost for TX’s, lower block time

  2. How is the account model not as great as the UTXO model for privacy? UTXO transactions are easier to see but harder to gauge who the recipient is.

  1. The account model dosen´t require much space in the block. Therefor it saves space and goes faster from A to B. The transactions is therefor more efficient transactions.

  2. Because its easier to track one transaction from another. When you send a UTXO it can have multiple outputs and its hard to sau where the money goes from to where

  1. It requires less space therefore more Tx in the block therefore less Tx time.
  2. Txs can be tracked.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? Takes up less space with not as much information.

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

  1. The bigger the block size it also increases the transaction fees,Ethereum with account model makes it faster to transact and much cheap and greater storage capacity.

  2. The UTXOs can keep transaction on the blockchain/leadger but account model doesnt keep track of transaction and it only update the wallet balance.

It’s a benefit because it saves a lot of data by eliminating the change outputs and showing only the sender, receiver, amount transferred, and a single digital signature.

  1. How is the account model not as great as the UTXO model for privacy
    The UTXO model makes it difficult to connect transactions by making it harder to trace the ownership of coins. The account model, on the other hand, by encouraging address reuse, makes it easier to create a transaction history for the user and hence, is not as good for privacy.

Homework on UTXO vs Account Model - Questions

1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
The account model saves the balance instead of keeping track of UTXOs which results in smaller block size and faster processing.

2. How is the account model not as great as the UTXO model for privacy?
The account model is not so great for privacy because it is a simple transfer from one account to another whereas in UTXOs multiple outputs are created.
“The UTXO model makes it harder to link transactions , whereas the account model provides better fungibility . When change addresses are consequently used in the UTXO model, it makes tracking the ownership of coins harder compared to the account model. With regard to fungibility , the account model offers better privacy. There is complete transparency of UTXO movements, read as assets, in the UTXO model when no privacy-preserving techniques are applied”.

  1. because the block can store more transactions
  2. you can see exactly how much money was sent, where it came from and who received it. With UTXO it could have multiple outputs so hard for people to tell where the money goes.

    1. Account model does not save each utxo as it stores balance of all transactions there reducing size of block making it faster
    1. With the account model, you can see and follow every transaction. It the UTXO model, you can have several outputs at the same time and can hide, to whom and how much you are sending.

  1. It saves storage space, thus decreasing the cost of running the blockchain for the users, and it also increases the number of transactions per block, making transactions faster.

  2. In the account model it can be easily tracked which account sends funds to which, because ETH tokens are fungible, unlike in the BTC UTXO model.

  1. Less space means more transactions. It is more efficient.

  2. If you know someone’s ETH address you can see their balance. With the UTXO model you necessarily don’t know if someone is sending money to themself. This is not as private but easier to trace.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    A: Because it can store more transactions in each block and have faster transactions.
  2. How is the account model not as great as the UTXO model for privacy?
    A: because you can’t send to multiple addresses like the UTXO model can.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    More space is always benefit

  2. How is the account model not as great as the UTXO model for privacy?
    Because in UTXO you cannot see which transactions were sent to yourself and which to someone else. In Account model you cannot send coins to yourself.

1. The account model doesn’t require as much space as the UTXO model; why is that a benefit?
Less required space for Ethereum means less required fees. The block size would also be reduced, probably also allowing for greater transaction speed.

2. How is the account model not as great as the UTXO model for privacy?
With the UTXO model, there can be multiple recipients and multiple senders in a single transaction. This “murkiness” creates more privacy. With the account model there is only one sender and one recipient per transaction.

Now that’s what I call an Answer. With capital “A”.

  1. Account model doesn’t require as much space as the UTXO model because each transaction means simply that one account (address) sent some value amount to another account, while in the UTXO model, it’s possible that one transaction (BTC) contain many outputs (many other addresses may receive BTC in one single transaction) and inputs, and, because of that, each transaction requires more space (bytes) than a simple transaction that just send some value (ETH) from one address to another. This is a benefit for the Ethereum Blockchain because it allows more transactions in a single block and, also, the deployment of lengthier smart contracts.

  2. The account model enables the possibility that, once someone has access to your address, this person may see every transaction that you sent, or received, and every other types of interactions you have previously had (such as deployment or interaction with smart contracts). The UTXO model, on the other hand, enables the possibility of one address sending BTC to many other addresses (outputs) at the same time, and those other addresses could belong (or not) to the same person that originated this particular transaction.

1 The account model not require as much space as the UTXO model because it does not need to store the entire history of transactions. This makes it more efficient and cost-effective, as it requires less storage space and computing power.

2 The account model is not as private as the UTXO model because it does not use a public ledger to store transactions. This means that all transactions are visible to the account holder, which can make it easier for third parties to track and trace transactions.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Ethereum account model updates transactions send money to point A and B. It’s less space, send exact amount of money and no further need to send back money.

  2. How is the account model not as great as the UTXO model for privacy?
    Less privacy and can’t send money back to yourself.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    that helps to save a whole lot of space, we would want to have as much space as possible for other tangible and relevant stuffs such as writing our code rather than UTXO

  2. How is the account model not as great as the UTXO model for privacy?
    we can’t really add any level of privacy to what we have going on such as creating multiple transaction in a single output to make it confusing for the public to figure what is the output outcome.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    its less space and exact amount
  2. How is the account model not as great as the UTXO model for privacy?
    its less privacy acount model but utxo are more private
