Bitcoin is not vulnerable to Quantum computer attacks, Andreas Antonopoulos has confirmed.
Speaking in a Q&A session, the celebrated commentator explained how Bitcoin’s hashes are resistant to quantum algorithms, making it all but impossible to infiltrate it with current technology.
“We don’t have very good algorithms for breaking hashes with quantum computing,” he said.
Responding to a question regarding whether the US National Security Agency, hereinafter NSA, had the quantum technology to crack Bitcoin, Antonopoulos simply replied, “yes,” but that they wouldn’t use it for that purpose.
“It is certain that the NSA has already built quantum computers. Google has one in their data center, and if they have one, the NSA has one that’s ten times better,” he continued.
“...Do they use that to break Bitcoin? The simple answer is ‘no.’”Full Read Here:
