Good morning @quipnetwork family, holidays time but always happy to share with you my quantum mind ☕️ There's a quantum attack vector that almost nobody in crypto is discussing and it's arguably more urgent than the "future" quantum threat people debate. It's called "harvest now, decrypt later." Here's how it works: Nation-state actors and sophisticated adversaries are harvesting encrypted blockchain data TODAY. Not to decrypt it now classical computers can't. They're storing it and waiting for quantum hardware to mature enough to break it retrospectively. Every transaction you've made. Every wallet interaction. Every signed message on-chain. If it's been recorded and it has, that's what a public ledger is it can be decrypted the moment the right quantum hardware exists. This isn't theoretical. Intelligence agencies have been running harvest-now-decrypt-later programs on classical encryption for years. There's no reason to assume blockchain data is being treated differently. My honest opinion: the people who say "quantum is a future problem" are right about the decryption timeline. They're wrong about when the collection of vulnerable data started. It started the moment you made your first on-chain transaction. @quipnetwork 's post-quantum wallet infrastructure protects forward from today. It can't undo the past. But it can stop the ongoing harvest from growing. Did you know about harvest-now-decrypt-later before reading this? And does it change how urgently you think about post-quantum security?
