Homework on UTXO vs Account Model

Ethereum 101
#1025
  1. The account model doesn’t require much space as the UTXO model, why is that a benefit? More room on the network and quicker transaction times
  2. How is the account model not as great as the UTXO model for privacy? There seems to be a contradiction. In one sense bitcoin UTXO’s are traceable going backward from a transaction Ivan talked about how a bitcoin is fungible in that you could determine that that particular bitcoin was used in say a drug transaction. Then in another sense Bitcoin is more private because in a transaction your output UTXO’s are not traceable because you can send to multiple addresses?

UTXO vs Account Model Homework

  1. The Account Model doesn’t require as much space as the UTXO model and so Etherium has more space to handle more transactions.
  2. The Account model is not as good for privacy because in Etherium even though you can see which accounts have sent you money you can’t see what individual coins represent which transaction.

1 Transactions get faster.
2 The transactions of the account model are much easier to track since they don’t have multiple input and output.

  1. More space = faster TX = smaller fees. + a more open network for miners to step in the game because requirements are easier to maintain.

  2. I can’t really relate fungibliness of ETH to its privacy and the same with BTC and non - fungibliness…HELP PLEASE

When you say: “you can see which accounts have withdraws and deposits”, does that mean you have a name on the account or smth? How could it be not private? My head cracks…

  1. The account model of ETH does not have inputs and outputs so blocks have more space to include transactions and smart contracts.

  2. The UTXO model is better for privacy because transactions can have multiple outputs.

  1. Less space requires less computing power and storage and therefore less processing time making it quicker.
    2.The transactions in the account model are easily tracked. It’s possible to see exactly how much money was sent and to which account

  1. The account model doesn’t require much space as the UTXO model, why is that a benefit?
    the added benefit is fungibility of ETH as characteristic. Also blocks are easier transferable and faster in terms of processing. No UTXO model which requires more data.
  2. How is the account model not as great as the UTXO model for privacy?
    On bitcoin blockchain all UTXO’s represent the history of every single bitcoin every created by miners. In theory the history of all coins is traceable. Account model provides an added layer of privacy in terms of fungibility but with Bitcoin Person A can transfer funds to Person B from the outside but in reality Person A sends funds to Person B and Person A all in 1 single transaction, thus BTC has added layer of privacy (optional not default).

1.) Faster, requires less space and it makes the account model more fungible.

2.) The account wallet is a single address and everything that address does is traceble, a utxo wallet can have multiple addresses in the same wallet that are unknown to others if you dont show there yours, this is an extra layer of privacy in my view.

It makes the network more usable for more coins. Anyone can make a coin or contract or both. This will make the New Web 3.0 bigger and better. Adoption as well. More big corporations are getting on board and that will bring a more robust economy for MORE people to use. More people = more value.

  1. Two benefits are: It can fit more transactions and is more scalable model then BTC.

  2. In the account model the transactions are easily tracked, because is possible to see how much was sent in a transaction. Is only possible send to one address instead of many as in UTXO model.

1 the account model is a ledger you dont need to trace the coins adventures it just show coming from one account into another it reduces data it also keeps all coins equal in value (you do not know what mischief the coins might have been involved with it might change their desirability thus their value)
2 account model i see what came from one account into another with utxo i could send 3 bitcoin into another address and have some come back to me as change or redirect a partial or complete payment with ledger the money shows in the account and leaves an account no areas of grey

1- The account model does not require space because it transacts one specific instruction at a time where as UTXO has more variant. It has input and output which could be changed in value or it could be redirected to a different destination.

2- UTXO could be harder to trace or transaction can be concealed giving it more privacy where as account model is more transparent.

  1. The account model saves more space, anytime you are saving space it makes processing transactions easier for the node/miner.

  2. UTXO’s can be split between destination address and “change” wallet and is difficult for someone to know the difference.

  1. Less space means you can put more transactions in each given block, making transactions times decrease thus making the network more efficient.
  2. In the account model you can only send transactions from account A to B. So you can see exactly where the transaction originates and is delivered to. In bitcoin you can split transactions and send them to multiple addresses all in one transaction.

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

You allow the network to become more efficient by saving space and creating a faster network due to less data due to the removal of UTXOs, as well as making the Ethereum blockchain more fungible in doing so.

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

In a UTXO model you are able to have multiple recipients in a transaction, allowing for more privacy due to the difficulty of seeing where each fraction of the ‘coin’ got split and to whom. With Ethereum it is account to account, and is simply expressed as -1 +1. One account sends, while the corresponding account receives.

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

    • You could fit more transaction in a block because the transaction size is smaller.

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

    • It is less private because you can’t mask you recipient address.

  1. More transactions can be processed at any point in time and less power is required for the account model.

  2. In the account model, the sender and recipient of the Ethereum transaction is transparent. However, in the UTXO model, it is possible to send Bitcoins back to oneself, the sender and recipient is less clear in a transaction.

  1. This means that each transaction is lighter and take less space than a single BTC transaction, this would create a block with way more transaction in it and so the blockchain way faster than the BTC one
  2. In the UTXO model you can send money to yourself in the same transaction as you can put more than one output, in this way we can’t really know which money went to a specific address; while in the account model it’s more the bank system where there is an account and this account can send money to another account and we can clearly see all the transactions in a transparent way.

  1. This is because account model transactions are only single debit and credits from one address to another while UTXO model is a collection of several transaction outputs toward many different addresses in same transaction. This lets you put more transactions into a block compared to UTXO blockchains.

  2. Account model does not allow you to hide transaction recipients so everyone can see who sends you money and who you sent money to.

1.Smaller transactions means lesser fees and faster processing.

  1. In the Account model you have a transaction from one account to another and it’s easy to follow. In the UTXO model one transaction can have multiple outputs, meaning it’s hard to follow.
