Is UTXO synonymous with leftover money in an address and the only reason UTXO is even a concept is due to security concerns of not changing an address after every transaction? Hence, your "unspent outputs" must be moved to x address.



Or am I missing something completely?



I read that you might have $10 balance in an address but your UTXOs might be $2 and $8 in the same address. How does this affect execution of a transaction on the blockchain?



Can somebody please shed some light on the difference between UTXOs and current address balance?



Thank-you!

          Not really. A UTXO is more like a particular bill or coin in that it's a specific "chunk" of value.



          The reason UTXO is a concept is because bitcoin is designed as a set of UTXOs rather than as a balance. It's the same way cash is designed as a set of bills and coins rather than a balance. When you say, "I have $100.43 in cash", you mean that you have some set of bills and coins whose value totals to that amount. This is analogous to a set of UTXOs in bitcoin.




          Or am I missing something completely?




          I think what you're missing is that bitcoin was not designed to have accounts with balances as the primary implementation but to instead have a set of unspent outputs.




          I read that you might have $10 balance in an address but your UTXOs might be $2 and $8 in the same address. How does this affect execution of a transaction on the blockchain?




          The blockchain doesn't care about addresses. If you have two UTXOs that you have the correct key(s) to claim, you can form a transaction that claims those two UTXOs and creates some new UTXOs as its output.




          Can somebody please shed some light on the difference between UTXOs and current address balance?




          A "current address balance" is the total value of all the UTXOs a particular key can claim.

            If you total the UTXOs, you get a number that you can think of as the balance on that address. But the blockchain itself doesn't give that number any particular meaning -- it's just UTXOs.
