Homework on UTXO vs Account Model

Ethereum 101

  1. Because it is faster and less storage demanding as blocks can include more tx which is key to the huge ethereum ecosystem.
  2. The account model is very easy to track, in the UTXO model for each tx you have many different inputs and outputs and quantities and recipients may be less clear.

  1. The account model doesn’t require much space as the UTXO model because it doesn’t have inputs and outputs, which means there’s no tracking of UTXOs.
  2. The account model is not as great as the UTXO model for privacy because you can see who sent you the transactions, but you can track or distinguish to see every transaction it previously came from. In the account model, you can only see your balances.

1 the result is less time and less fees
2 Because of transparency. A ledger model operates on adjusting balances on a database,each node as well as the public have access to the latest version of the blockchain making it easier to visually follow account movements.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    It just has to save a balance, not all the amounts from x number of addresses - this makes it cheaper to send txn.

  2. How is the account model not as great as the UTXO model for privacy?
    It is based on the the wallet account and not on the non fungible bitcoin. To increase privacy in BTC one can send a txn to oneself and another wallet address in the same txn - in ETH you cannot.

1.It is a benefit because it provides room for more efficient and faster transactions.

  1. The Account model lacks privacy and is non fungible

Well one of the first things that we have to consider is that the account model doesn´t keep track of all the history of the UTXO´s, therefore in the ETH blockchain the blocks include a lot more of transactions instead. In the Bitcoin Blockchain you can see all the transactions made with specific BTC (all its background), while the account model used on Ethereum only adds and subtracts the value and you cannot send them to yourself.

    • It won’t require as much computing power and storage. In essence, the Network is more flexible and faster.
  2. How is the account model not as great as the UTXO model for privacy?
    • With a UTXO model you can send money to several addresses in the same transaction including sending some money back to yourself. This feature adds a certain level of privacy. In the account model, each transaction simply updates the account balance and there is no way to do several of them to a different account in the same transaction.

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

The UTXO model is structured in such a way that each transaction consists of many unspent transaction outputs being grouped together to form inputs to the current transaction and then outputs from the current transaction going to the recipient(s) and/or some btc going back to the user.

With the account model there are no UTXOs just one single transaction going from the sender to the recipient.

This saves space in the blocks on the ethereum blockchain but has the minor downside in that transactions are more visible, so privacy is only very slightly decreased.

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

Because each transaction in the btc UTXO model consists of multiple unspent tx outputs from previous transactions as inputs and because each transaction most likely will contain multiple transaction outputs, there is another layer of privacy so to speak in that it is difficult to find out how much btc is actually going to the recipient in any given transaction.

With the account model this concept of UTXOs is eliminated and each transaction consists of a delivery of funds from point to point or from sender wallet address to recipient wallet address, allowing participants in the network to see exactly how much eth is exchanging hands in any given transaction.

  1. It is beneficial that the account model doesn’t require much space as the UTXO model because it only updates the TX data from account(s) - “A” to account(s) - “B” rather than storing a full copy of blockchain on propagated nodes to meet consensus.

  2. Ethereum account model is not as great as the UTXO model for privacy because Tx Inputs interoperate from Account (A) to Account (B), updating the balance, and not the traceable TX data from a single or multiple TX Inputs / Outputs on BTC Nodes ; Network Blockchain.

  1. it is a benefit that allows Block contain more Transactions; increases speed; requires less computing power
  2. it is not necessarily not as great it is just that you cannot send money back to yourself during the transaction which makes it less private and you cannot trackback each individual coin.

  1. The account model transaction requires less space on the blockchain. A smaller blockchain requires less storage and less network traffic; therefore less space is better.
  2. A transaction in the account model only involves one sender and one receiver address. In the UTXO model several inputs and several outputs are involved. A single UTXO transaction can send funds to several addresses, some which may (or may not) belong to the sender. This makes it more difficult to track who actually received the funds.

  1. Because it take up less memory make it easier for someone to run a full node
  2. Because you can’t hide you spends

  1. The account model save space and more transactions can fit into a block, this increases the speed, and reduces the fees for transactions. Saving storage space is always a benefit on such a huge network.
  2. Since the account model for Ethereum shows how much was sent to another account for single transactions. In the UTXO model several transactions can be made and it would not be known who got what amount.

  1. The account model doesn’t require as much space which is beneficial because blocks can include more transactions.

  2. The account model isn’t as great as UTXO for privacy as with UTXO the transactions are basically untraceable you cannot confirm where payments are sent to exactly or the exact amount sent to each party. With the account model there are no change wallets in Ethereum, so the addresses are specified and you can track where money has been.

    It is simpler. Lower costs.

  2. How is the account model not as great as the UTXO model for privacy?
    There is no way to send money back to yourself. You can see exactly how much money you sent and to what address.

  1. It takes less space than utox model which make tx go through BC faster as you can only send from A to B
  2. An account model is less private. You can only send from A to B ( not to multiple accounts including yourself) and anyone can see that.

  1. This allows for a more efficient network, where it is much easier for individuals to run nodes as it will cost less due to less information needed to be stored.
  2. In the UTXO model you can become on of the outputs in a transaction in which you were an input, so it is not possible to see exactly how much BTC was sent to each output in a transaction.

1)This is beneficial because storing the blockchain requires less space - less storage then.
2) That is because in UTXO model you can send two transfers in one transaction - one to X and one to yourself and nobody will know which transfer goes to X and which back to you. And account model you can check the balance and see how much less money you have and how much more money X has.

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    Every transaction is smaller and saves space, which is good for the nodes and processes things faster,

  2. How is the account model not as great as the UTXO model for privacy?
    It is not as private because the account model doesn’t have the concept of an input and output (which can be multiple). The account model code is public and balances are public.

Utxo uses more space then the account model. This means less space more transactions.

In the account model you can see from where to where the sent amount goes. Therefore less privacy.
