The Architecture of Digital Scarcity: Why Bitcoin is True Intern

If you copy a digital photo, you have two photos; if you copy a digital dollar, the entire financial system breaks. ​For decades, computer scientists tried to create digital money, but they always ran into the same wall: the digital world is built for endless copying. To stop people from spending the same digital token twice, early systems had to rely on a central company—like a bank or PayPal—to act as the ultimate referee.

​Bitcoin changed everything by eliminating the referee entirely. It isn't just a software app; it's a self-sustaining network that uses simple physics and economic incentives to keep thousands of strangers completely honest. In this beginner-friendly session, we will strip away the financial hype and look at the core mechanics that allow Bitcoin to exist as secure, un-copyable internet money.
