Trading Notes | UTXO and Account Models
① Ethereum uses an account model: the blockchain directly records each account’s balance. A transfer deducts from one account and adds to another.
② 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.
③ After sending Bitcoin, if you notice that some coins went to a new address of yours, that’s generally change—not lost coins.
