Study Notes | UTXO and Account Models
① Bitcoin uses the UTXO (Unspent Transaction Output) model: each transaction consumes several existing outputs and creates some new outputs.
② Ethereum uses the account model: the blockchain directly records each account’s balance, and a transfer deducts funds from one account and adds them to another.
③ Receiving funds at the same Bitcoin address every time exposes your transaction history. Many wallets default to using a new address for each incoming payment and change.
