The “balance” shown in a Bitcoin wallet—is there really a number like that stored on-chain?
It’s worth understanding the difference between the UTXO and account models.
In the UTXO model, unrelated transactions can be validated in parallel, and using a new address to receive change can also help protect your privacy. The trade-off is that writing complex smart contracts is less convenient.
If something is unfamiliar, avoid taking a large position at first. It’s safer to try it with a small amount.
$BTC uses the UTXO model. The balance shown in the wallet is actually the sum of multiple unspent outputs. Currently: 82589.99.
