: Focus on these "Three Cs" first. Who is your main character, what is their situation, and what is stopping them from getting what they want?.
: Take a technical concept (like a hash) and ask a "what if" question. For example, "What if this code controlled every bank account on Earth?".
If this hash was active, it meant someone had successfully bypassed the world's most secure encryption to launch a decentralized currency backed not by gold or debt, but by private data.
