Bitcoin, Nostr, and the Quantum Problem

Washington just made quantum a national priority, and governments don’t scramble funding for science fair projects. This one walks through why quantum is a sovereignty story before it’s a tech story. Who’s positioned (IBM, Google, IonQ, the post-quantum security plays), where the durable money actually sits, and the part that should keep you up at night. Quantum doesn’t threaten proof of work. It threatens the signature layer. Your keys. Same problem hits Nostr, except there the keys secure your voice and your identity instead of your coins. The near-term defense isn’t exotic math. It’s hygiene. Fresh addresses, no reuse, treat key management like the first-class problem it is. Quantum isn’t just a threat. It’s a forcing function, and it’s about to test whether the decentralized world can keep its promises when the cryptographic floor starts moving.
