The Migration Race Nobody Talks About. Post-quantum signatures are the main line of defense.

The first sign of a quantum attack on crypto might not be a headline. It might just be a wallet going empty — no trace, no explanation, no culprit.

Christopher Smith, CEO of Quantus Network, thinks that's exactly how it could play out. Bad actors who crack elliptic-curve cryptography won't necessarily announce themselves by…

It's a chilling scenario, and not an implausible one.

Satoshi's Bitcoin stash — worth around $63 billion — gets all the attention when people talk quantum risk. But Smith thinks that's probably not the first target.

8 / 15

That's the thing about plausible deniability. A quantum-capable attacker doesn't need to announce what they've done.

Smith puts the odds of quantum computers threatening modern cryptography at roughly 50-50 by 2028.

Sean Cheetham of Blockchain Capital sees the early 2030s as a more realistic window. Michael Coates of the Solana Foundation is even more skeptical — he's pointed out that the…

That skepticism isn't unreasonable. Quantum hardware is genuinely hard to scale. Error rates remain a serious problem.

Google accelerated its own post-quantum cryptography transition timeline to 2029, partly because of exactly that kind of AI-assisted breakthrough.

Roy Blackstone, CEO of NGRAVE, doesn't mince words on what happens if blockchains aren't ready. Catastrophic, basically.

Post-quantum signatures are the main line of defense. Blockchain networks are actively working on migrating away from elliptic-curve cryptography toward cryptographic schemes…
