Transaction Notes | UTXO and Account Models
① Bitcoin uses the UTXO (Unspent Transaction Output) model: each transaction spends some existing outputs and creates new ones.
② The fee for a Bitcoin transaction is the sum of all inputs minus the sum of all outputs. This difference goes to the miner who includes the transaction in a block.
③ If you notice that some bitcoins were sent to one of your new addresses after making a transfer, they’re usually change—not lost coins.
