Ask HN: What Kind of Threat Does Quantum Computing Pose to Bitcoin?
5 by jcuenod | 2 comments on Hacker News.
My understanding of quantum computing and what it can do is popular mechanics level at best. I have heard people dismiss bitcoin as inevitably insecure "because of quantum computing" and, conversely, I've heard people dismiss quantum computing as hype, the reality of which lies too far in the future to worry about. Is the concern simply, "we don't know how this could change the computing landscape," or is something more like "quantum computing promises to calculate primes in O(1) time, rendering keypairs worthless"? And how far out are we realistically?
