Most Investors Think Quantum-Resistant Means Safe Forever BUT... That's Not What Cryptographers Mean!?

The more I've dug into "quantum resistant" crypto projects the more I've realised most investors (including me originally) misunderstand what that phrase actually means.

When I used to hear "Quantum resistant blockchain"

I used to interpret it as "This project is safe from quantum computers"

But I've learned that's not what it actually means at all.

What it really means is based on everything currently known, no practical quantum attack is known YET. RSA wasn't broken because quantum computers became faster. RSA was broken (theoretically) because Shor found a completely different way of looking at the problem. He found hidden structure that classical computers couldn't exploit efficiently. That's what initially got me thinking...

When blockchain projects market themselves as quantum resistant because they use lattice cryptography, are they saying "we know this is safe against future quantum algorithms" or are they saying "nobody has found the quantum equivalent of Shor yet"?

I actually went away and built a small research framework trying to understand this distinction better. What surprised me most wasn't that I found a way to break lattice cryptography (I obviously didn't), it was discovering how much uncertainty still exists underneath the marketing language. The cryptographic community does not claim lattice cryptography is quantum proof. The claim is much narrower and more like:

- no efficient quantum attack is currently known
- many smart people have looked
- several hardness reductions exist
- and lattices remain our strongest major post-quantum candidate

I am posting this to raise awareness because thats very different from these QR blockchains being immune from being broken. In finance people price uncertainty all the time but when it comes to post-quantum projects many investors seem to treat "quantum resistant" as if it means "solved forever". Personally I now think the question isn't whether lattice cryptography is broken, it's whether investors understand the difference between the best known candidate VS proven future proof technology... Most don't and I didnt until recently.

Curious how other people think about this.

When a blockchain markets itself as quantum resistant, what level of confidence do you think investors should actually attach to that claim?
