- —Litecoin, Dogecoin, Zcash, Bitcoin Cash and Dash also use the UTXO model

- —The term UTXO emerged among developers around 2011–2012, not in the whitepaper
- —The model prevents double-spending without a central authority
Why it matters: The reminder highlights Bitcoin's foundational design and how UTXO chains differ from account-based networks such as Ethereum.
