Keep in mind that Bitcoin and its blockchain aren't quantum-safe. The network would have to undergo a hard fork to migrate away from legacy signatures. Who knows how long that's going to take and when it will be needed. Lock uses a combination of traditional, non-quantum-safe cryptography and a quantum-safe system. I don't have the technical know-how to comment on how that would work on a blockchain that itself isn't protected against the worst-case scenario and what would happen to Lock in case a quantum attack happened.
Yeah, you are correct, as this is a very concerning and important matter these days.
Because we, as its adopters, fear what would happen if a quantum computer damages/attack its network in any way.
At the same time, if we think about it from another perspective, we know that every technology has its pros and cons.
So what if this technology is used to make it safe from bad actors to protect it rather than damaging it in any way?
The meaning of this is that it will depend on the situation and what kind of people/person is using this technology.
This will decide whether quantum computing is a technology against this asset or supports it.
Other than this, what I think is that, as adoption of Bitcoin is increasing day by day, and now it has reached the international level where we have seen it also has been added to some countries' strategic reserves, e.g., the US. So I don't think countries like these or big powers will ever let this happen. Because if this happens, it will also damage them, which can impact their economy, right? CMIIW!
