Understanding Bitcoin: Unspent Transaction Output (UTXO)

Understanding how the blockchain works with transactions, not balances is a key concept, and in particular, how unspent transaction output works (UTXO)

I have been trying to understand this concept for a while, and your video was pretty good at explaining it. Thank you sir!

[nahomg]

This was a perfect explanation of UTXOs, you explained it better than my university lecturer. Thank you! 👍

[aave]

This is probably the best explanation I can get anywhere online! Thanks!

[bradleyjuma]

Hi. Could you help me with some unspent funds that is just sitting on block cypher. I sent it to a wrong address by mistake and I am wondering if there is a way to get those back since it is unspent because it wasn’t a valid address. Frustrating

[FidoeFTW]

Thank you so so much my friend. You explained it very well and I understood the basics of UTXO very quickly.

Why do some blockchains like Digibyte say they have the longest "UTXO" blockchain, are there different types of blockchains other than this?

So the wallets create a new 'change address' that is connected to your originating address? BC on the Blockchain Explorer, it shows my originating address is less, but if I add in the newly generated 'change address', it adds up to the correct amount.

* can this be cancelled by any chance? and how long may it take TIA

"privacy concerns if you keep using the same change address VS sending to a new address which is preferred"
I don't get this. The wallet creates a new address for the "change" sent back to me each tx? But my receiving address doesn't seem to change after every tx I make..?

Waiting for your reply,
Thankyou.

How does the change transaction work? If you want to send someone 0.05, but you have 0.10, do you make a second transaction to send 0.05 back to you? How do you make a transaction from another person? Do they have to sign it? Or do you send 0.05 to the receiver and 0.05 to yourself in the output?

So my question is, how do you send fix this issues, especially when the you've sent Bitcoin to a wrong address or an address that you are unsure where you got it from??
