#量子计算威胁 Does quantum computing threaten Bitcoin? This wave of public opinion is really quite interesting. On one side, Nic Carter says that 1.7 million Bitcoins are at risk, while on the other side, Bitcoin Core developer Jameson Lopp directly dismisses the urgency—there's no need to panic in the short term, and any protocol changes would take at least 5 to 10 years.

I looked into the details and feel that this matter isn't as urgent as it seems on the surface. Quantum computing is indeed a potential threat, but it's still in the "theoretically feasible" stage, and cracking the Bitcoin network is still a long way off. The funniest part is that someone pointed out that the fund backing Nic Carter has invested in a quantum-resistant tool company—this is very representative, creating anxiety on one hand and making money on the other.

But Lopp is also right; we should be prepared just in case. If an upgrade is really needed, it will be a major event involving the entire system—fund migration, consensus modifications, all of which are significant. So now is the time to start preparing plans, but there's no need to be scared right now.

Such things are common in the crypto world—when a hot topic emerges, various players act according to their interests, and the truth is often drowned out by information noise. What we, the onlookers, should do is listen to multiple perspectives and not let a single viewpoint hijack our thinking.
