UTXO’s are the amounts of BTC as the output of a transaction.
-
You would be out of luck and the transaction would be declined.
-
The wallet would, take the Input - the output to find the transaction fee.
-
By not knowing the person behind an address, this would allow you to send yourself the same amount of BTC in multiple transactions which would appear as if the BTC was spent to several different people.

Thank you @Maki. Right… My all UTXOs are assigned to my address and kept separately. Thus, if a single UTXO isn’t large enough to satisfy the demand of the input amount, then the wallet will use a second, a third, etc until the total is greater than or equal to the amount your sending.
Have a great day!

- Describe what Unspent Transaction Outputs (UTXO) are.
It is the balance in your wallet - What would happen if you don’t have any single UTXO that is large enough to cover for your transaction? It stays in the wallet
- How would a bitcoin wallet specify the transaction fee when creating a transaction? Input-Output. It checks the blockchain for the fee.
- How could you use the notion of transaction inputs and outputs to increase privacy in your transaction? You could send the money to another wallet which belongs to you.

- UTXOs are Unspent Transaction Outputs. These are the amounts that come from the inputs before they get sent out as outputs.
- If a single UTXO is not big enough the wallet will add any additional inputs until it gets enough to cover the total outputs.
- The wallet will find the best transaction fee at the time based on other transactions on the blockchain. It will then specify the fee as the difference between the transaction and the remainder or change that you get back.
- Make use of multiple output addresses.

Q: Describe what Unspent Transaction Outputs (UTXO) are.
A: UTXOs are the balance of the wallet.
Q: What would happen if you don’t have any single UTXO that is large enough to cover for your transaction?
A: The transaction doesn’t happen.
Q: How would a bitcoin wallet specify the transaction fee when creating a transaction?
A: Input = Output + Transactions fee. The wallet tracks what UTXOs your wallet can use and then it calculates your fees based on the current and previous transactions.
Q: How could you use the notion of transaction inputs and outputs to increase privacy in your transaction?
A: By using some inputs and outputs instead of one.

You can use multiple UTXOs as inputs to a new tx. If you still don’t have enough then your tx would be declined.

Describe what Unspent Transaction Outputs (UTXO) are.
When a transaction takes place, there is an input and an output. Before these outputs become an input for another transactions, they are UTXOs. -
What would happen if you don’t have any single UTXO that is large enough to cover for your transaction?
If a wallet does not have a single UTXO large enough to cover the cost of the transaction, multiple UTXOs can be used. If all UTXOs are still not large enough, the transaction is declined. -
How would a bitcoin wallet specify the transaction fee when creating a transaction?
It is the input minus the output. -
How could you use the notion of transaction inputs and outputs to increase privacy in your transaction?
It is impossible to tell who the sender is, and who the recipient is. As input = output, if part of the output is sent back to the sender, it is even harder to determine where the outputs have gone, thus making the transaction more private.

Your wallet will calculate the sum of your total unspent transactions to equal the amount needed, if not enough the transaction is not allowed to take place.

A transaction will result in UTXOs. A wallet can query the blockchain for UTXOs using it’s private key and determine the owner’s available balance by summing the UTXOs.
-
A transaction can have multiple inputs, so more than one UTXO would be used.
-
A wallet will derive the fee automatically based on inputs = outputs + fee
-
There can be multiple receive addresses in a single transaction, and the recipient can control one or many of these addresses. It is more difficult to determine the actual amount received, because outputs can be split between the addresses.

UTXOs are the total amount of unspent outputs accumulated from previous inputs.
-
My wallet automatically adds up all UTXOs, and if the total UTXO is large enough to cover the transaction, the transaction will pass. If not, the transaction will fail.
-
Fees are calculated by deducting the output from the input.
-
By creating more output addresses.

- Describe what Unspent Transaction Outputs (UTXO) are.
UTXOs are unspent transaction outputs. They are the sum of all transaction inputs in your wallet, aka the balance.
- What would happen if you don’t have any single UTXO that is large enough to cover for your transaction?
If you have no single UTXO large enough to cover a transaction, then your wallet will sum up and combine other UTXOs in order to cover the transaction amount. However if there are not enough UTXOs available to cover a transaction it will be invalidated.
- How would a bitcoin wallet specify the transaction fee when creating a transaction?
A BTC wallet will check the blockchain and decide on a reasonable transaction fee to recommend to its user. This recommendation will be based upon recent transaction fees paid on the blockchain by other participants.
- How could you use the notion of transaction inputs and outputs to increase privacy in your transaction?
In order to increase privacy one could send multiple transactions to different wallets owned by the same individual in order to confuse anyone checking on the public ledger. As addresses are not specifically linked to an individuals identity it is quite difficult to link UTXOs to a specific individual.

UTXOs are created from the previous transactions as unspent outputs. Kind of like change from a money transactions.
-
The Transaction would be denied
-
In most cases the bitcoin wallet would search the blockchain and then come up with a fairly fast transaction that would be fairly priced from other data on the blockchain.
-
Anonymity is provided by bitcoin transactions as output can be sent to multiple channels as well to same input channel. No one would know who the wallet belongs to, except the private key owner.

1.) UTXO’s are output transactions that are sent to you and have not been spent so they essentially just sit in your wallet.
2.) Your wallet will automatically calculate a sum of your UTXO’s and send back an output as change.
3.) Your wallet will generate the best fee possible to get you into the blockchain reasonably the fastest by looking at previous transaction fees in the blockchain.
4.) You could send out outputs to 2 different addresses, one of them belonging to you only.

Describe what Unspent Transaction Outputs (UTXO) are.
Your wallet balance that represents the unspent inputs from the previous transaction -
What would happen if you don’t have any single UTXO that is large enough to cover for your transaction?
The individua UTXOs read by the wallet will be summed up and used to pay the transaction. If there is not enough funds then, the transaction will simply be invalid and won’t go through. -
How would a bitcoin wallet specify the transaction fee when creating a transaction?
It will be the difference between the transaction input and the transaction output. Because of the fee, the actual output will be slightly less than the input and that difference will be the transaction fee portion. -
How could you use the notion of transaction inputs and outputs to increase privacy in your transaction?
There is no viewable personal data associated with the UTXO nor anyway of using it to derive the private key. You can also generate more output addresses.

- UTXOs are unspent outputs from a previous transaction that is now in your wallet.
- Granted that the sum of all your UTXOs is still not enough, it would be rejected.
- The wallet determines the fee by the amount of data that makes up the transaction. The wallet will propose a fee that can execute your transaction the fastest.
- Generate multiple output addresses.

Thank you for your input. Much appreciated
Cant visualize most of this yet, but its all getting slowly clearer.
