“No, the NSA is not going to hack us with their quantum computer,” Antonopoulos detailed to the crowd. “The interesting thing is what happens when that technology becomes commercially viable and more broadly available. That’s where you see two of Satoshi’s initial design choices that in retrospect are absolutely genius. First of all, Bitcoin uses two fundamental cryptographic systems in order to achieve its security. One is elliptic curve multiplication on a prime field which is a one-way function. That depends on prime factorization mathematics which is vulnerable to quantum technology. The other is hash algorithms, and hash algorithms are not actually factorizable with quantum technology. We don’t have very good algorithms for breaking hashes with quantum computing.”
