News Bitcoin - Antonopoulos Details Bitcoin’s Two Layers of Protection Against Quantum Computing

An attendee listening to a keynote speech given by Andreas Antonopoulos asks: “Is it possible, for example, that the NSA boasts a quantum computer that will be able to break Bitcoin’s cryptography?”

“Yes, it is certain that the NSA has already built quantum computers, because Google has one in their data center, and if they have one the NSA has one that is ten times better, that costs as much as a moon mission and that can break encryption systems at a much better rate and with more efficiency,” explains Antonopoulos. “Now here’s the interesting question — Do they use that to break Bitcoin?”

“The simple answer is ‘no’. We know from history that if you have such a thing, this is the most important and well-guarded secret. Any time you use it you have to come up with a parallel construction story that tells the world how you managed to break that encryption without using such a thing, because such a thing doesn’t exist. When the British captured the Enigma they would let ships sink because they didn’t have a good enough story of how they knew the U-boat was going to be there. They let cities be bombed because they didn’t have a good enough story of how they knew they were going to be bombed and so if they couldn’t create a good enough story they could not risk revealing the most important secret they have.”
