How do Bitcoin and Ethereum differ in the way they keep track of transactions? Don’t worry—the class rep is here to explain:
Bitcoin uses the UTXO (Unspent Transaction Output) model: each transaction spends some existing outputs and creates new ones.
The Bitcoin balance displayed in your wallet is calculated by adding up all the UTXOs that belong to you. There’s no “balance” field on the blockchain.
The most expensive thing in crypto has never been transaction fees—it’s the cost of not understanding the rules.
