  1. less space, easier to transfer, faster proces
  2. less privacy possible with ethereum, utxo you can sen do your own addrs

  1. It means the blockchain takes up less space and so it is easier for Nodes to download and sync with the blockchain. It also means that transactions take up less space in a block so there can be more transactions per block.

  2. The account model simply updates accounts in the database with exact amounts. You can send an exact amount from A to B. There is no way to send money back to yourself as part of a transaction output so you can’t disguise where money is being sent.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    One block can store more Tx with less space , confirmation is faster.

  2. How is the account model not as great as the UTXO model for privacy?
    Individual inputs and outputs of all Tx can be traced easy, Account Model is the balance of account transferred from Payor to Payee

    More transactions can be put into a block in the account model.
  2. How is the account model not as great as the UTXO model for privacy?
    UTXOs can be sent to the other recipients and yourself at the same time which makes it harder to trace.

    You can put more transactions in one block and takes less time

  2. How is the account model not as great as the UTXO model for privacy?
    You can track the sender and recipient of each transaction form the contract

    less space per transaction means more transactions per block.

  2. How is the account model not as great as the UTXO model for privacy?
    with the UTXO it is possible to trace on coin level where the TX is coming from. with the account model this is not really possible. there is no traceability of the coin and also no distingish between coins

  1. As less space is needed to store a single transaction, it is possible to store more transaction in a block. That improves scalability issues.

  2. With ethereal you can’t send back money to yourself, as it is possible to spend the excat amount required for a transaction. With bitcoin it is hard to distinguish the transaction from sending money back to yourself, that makes it harder to track.

  • The account model doesn’t require much space as the UTXO model, why is that a benefit?
    This allows for fast transaction times, as there is less data needed to complete. Furthermore this makes transactions cheaper.

  • How is the account model not as great as the UTXO model for privacy?
    You can see who has sent you “coins” with the account model.
    With UTXO’s 'you can spend in a grouping, you can also send part of this transaction back to your self, this makes it very difficult to know what you are doing with your Satoshi’s. However UTXO’s history can be tracked, what address the UTXO’s have been held in. There is an un-erasable record of each and every UTXO’s movements.

1-The account model doesn’t require much space as the UTXO model, why is that a benefit?
It’s a benefit because less space in a block is needed, so you can put more transactions in a single block. It means it’s faster and cheaper

2-How is the account model not as great as the UTXO model for privacy?
UTXO is better in terms of privacy because you have outputs that will go to another addresses. That addresses can be other person or yourself, and can’t be known from outside. So in a single transaction, you can send btc to other person and to you again and no one knows that it’s happening like that.
Account model just update balances between addresses, something more similar to bank accounts. You send 1 Eth to other person, so you’ll have -1 and he/she will have +1 Eth. Furthermore, in the same transaction you can’t also send back to you money, for one reason: You move mone from A to B, but not to A+B+C in the same transaction. If you want to send money to you, you should send mone from an Account A to an account B and both would belong to you.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Less space required per tx, allows more them to be added to each block; which speeds up the tx settlement time per tx.

  2. How is the account model not as great as the UTXO model for privacy?
    Because unlike the UTXO model, the account model doesn’t allow you to send multiple transactions at once. This make each account model tx more transparent on the blockchain and traceable to the receiving address.

Because it makes the blockchain and the network faster, as less data needs to be handled and distributed. (More transactions fit into blocks.)

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

You can include various outputs in an UTXO, which makes it difficult for an outside observer to tell what part of the money went to whom. For example, a person might pay for something while simultaneously sending 2 other transfers to friends and 2 additional transfers to addresses that are under the sender’s own control - all in the same transaction. This is not possible in Ethereum’s account model, where a person just can send 1 transfer per transaction and sender and recipient are therefore less difficult to deduce.

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

    Ethereum wallets require less space using the account model by just holding values, compared to a Bitcoin wallet that uses the accumulation of unspent transaction outputs to create a total. This requires more space as it stores more transactions needed to fit into a block.

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

    The account model provides transparency of transactions indicating where they are being sent. In comparison to UTXO transactions, they can be modified by sending transactions to hidden outputs.

    faster processing and more functions available.
  2. How is the account model not as great as the UTXO model for privacy?
    maybe I misunderstood but I though it was more fungible and therefore bit more private since you cant trace origin of the the txn and blacklisted coins… combining UTXO would just corrupt the whole balance, in the eyes of the law. one would think…

  1. A practical example is that Bitcoin recently had polemic discussion about its blockchain size, transactions capacity and fees that resulted in a network fork. Based on that, I assume that space is important in the blockchain since block may store more transactions or smart contracts so to speak.
  2. With UTXO model, even though you can track the inputs and outputs, in one transaction you may send to 2 or more addresses making difficult to investigate to where it was sent and to whom. But with Account model, it is easier to follow since it moves from A to B.

    • The account model doesn’t require much space as the UTXO model, why is that a benefit?
      A: Each transaction is smaller, resulting in lower fees per byte and less clutter in the block, as well as faster transaction times.
    • How is the account model not as great as the UTXO model for privacy?
      A: You cannot obfuscate transactions by sending funds to yourself and to someone else in the same transaction. In the UTXO model several outputs can be sent in one transaction and it is harder to know who it is going to. With ETH it is much simpler, funds flow from one wallet address to another.

  1. Less space = faster = lower price
  2. It is weigh easier to trace account transfers/balance on the account model than tracing inputs and outputs and not know which output goes to recipient and which one goes maybe back to the referrer, like we have on UTXO model

  1. I t only keeps track of the account totals no history can be traced to previous transactions.
  2. In btc you can send money back to your self and no one knows where the outputs are going. In the account model the transactions are more transparent because for instance you send the exact amount and cannot send your self change.

The account model doesn’t require much space as the UTXO model, why is that a benefit?
The account mode saves space in blocks. This will make transaction faster and more efficient . Ethereal can run a smart contract. Less data capacity may attract individuals as node.

  • How is the account model not as great as the UTXO model for privacy?
    Account model can send one transaction at a time and you can see exactly from which account money was sent to which account . UTXO can have several transaction at once and you cannot see who sent where from outside.

  1. With less space it makes allows it to be faster.
  2. Account model you can track A send to B. UTXO you can send to multiple accounts making hard track and to know which address is the same as its senders.
