Quantum computing headlines increasingly suggest bitcoin is on the verge of collapse, with claims that future machines could crack its cryptography in minutes or overwhelm the network entirely. But academic research paints a more constrained picture. Some widely cited "breakthroughs" rely on simplified problems that don't reflect real-world cryptography. And quantum attacks on Bitcoin? The energy required is equivalent to a small star, according to research papers shared on X by Bitcoin hardware entrepreneur Rodolfo Novak. Bitcoin's security rests on two different kinds of math, and quantum computers threaten them in two different ways. One, known as Shor's algorithm, targets...
