The greatest threats to crypto have emerged in every shape imaginable over time: hacks, fraud, bans, leverage, collapse.
Today, the single greatest threat to crypto is Quantum Computing.
Every threat before it was a human failure. Bad code, bad actors, bad leverage, bad governance. Painful, sometimes criminal, but fixable. You patch the exploit. You regulate the custodian. You de-lever the system. The technology underneath kept working.
Quantum computing isn't a human failure. It's a mathematical fact arriving on a countable clock.
Elliptic-curve cryptography, the thing securing nearly every wallet and chain on earth, rests on one assumption: certain problems are too hard for any computer to solve. Quantum computers don't solve that problem faster. They dissolve the assumption entirely.
And the exposure isn't future-dated. Every public key ever published on a ledger is already sitting there, permanently, waiting.
Every blockchain, every wallet, every exchange, every piece of infrastructure holding value today will eventually have to rely on post-quantum cryptography. There's no fork, no insurance fund, no auditor coming to fix this one after the fact.
For developers, the decision is simple: build on a chain that's post-quantum native from the ground up, not one that promises to retrofit it later.
The clock already started. Slowly, then suddenly.
