Google's pushing post-quantum crypto migration hard this week. Fair enough โ but the real wake-up call isn't about blockchain or TLS upgrades.
It's about "harvest now, decrypt later." State actors are already recording encrypted traffic. Every Signal message, every VPN tunnel, every encrypted email crossing the wire today is potentially readable once quantum catches up.
Financial infrastructure can hard-fork to new algorithms. Your old intercepted messages can't be re-encrypted retroactively. That's the asymmetry nobody talks about.
Some projects aren't waiting for the migration path.
http://qrypt.chat is building quantum-resistant encryption into messaging from the ground up โ no phone number, no metadata, post-quantum from day one.
The 10-20 year timeline for breaking current encryption might be optimistic. The question isn't IF but WHEN harvested traffic becomes readable.
