Addressing Bitcoin's Quantum Computing Challenge: BIP 360 Discussion with Hunter Beast | MIT Bitcoin Expo 2025

Can Bitcoin survive a quantum future? At the 2025 MIT Bitcoin Expo, Bitcoin Magazine's Technical & Opinion Editor Shinobi sits down with Hunter Beast, author of BIP 360, to explore the existential threat posed by quantum computing to Bitcoin’s cryptography.

Hunter breaks down the difference between physical and logical qubits, explains how Shor’s Algorithm could crack ECDSA, and details his proposed post-quantum migration path for Bitcoin. They also discuss game theory, government signaling, and how legacy coins from early Bitcoin days might be exploited — or saved — with proposals like Hourglass.
