🗂️ Technical principles | UTXO and account models
· Definition: A UTXO can only be spent in its entirety. If the payment amount is less than the UTXO's value, the excess is returned to the sender's address as change.
· Why: In the UTXO model, unrelated transactions can be validated in parallel, and using a new address to receive change also helps protect privacy. The trade-off is that writing complex contracts is less convenient.
· Reminder: If you notice that some of your bitcoin has gone to a new address of your own after a transfer, it's usually change—not lost coins.
