Son: Dad, did you know that Bitcoin transactions are recorded in blocks on a chain called the blockchain?
Dad: Son, I have heard the term "blockchain" before.
How does it prevent double-spending?
Son: Each bitcoin can only exist in one block at a time, so it can't be in two separate blocks simultaneously. What we call "bitcoin" or "coin" refers to an unspent transaction output, alternatively identified as "UTXO".
Dad: Ah, got it. That ensures the integrity of the transactions then.
Son: Exactly, Dad! It's one of the reasons why Bitcoin is considered secure and trustworthy.
