Explain the Concept of ‘Double-Spending’ and How Blockchain Prevents It.

Double-spending is the risk that a user could spend the same digital currency more than once. Blockchain prevents this by requiring all transactions to be confirmed and recorded on a public, immutable ledger.

Once a transaction is validated and added to a block, the network consensus ensures it cannot be reversed or duplicated, maintaining the currency's scarcity.
