David Chaum, the god of cryptocurrencies: Bitcoin still has time before quantum computers pose a real threat to their password integrity.

David Chaum, the godfather of the cryptocurrency and the founder of the first digital currency (Digicash), said in his talk about "Google Quantum Computer Progress": "Google's news of quantum superiority has strengthened my belief that quantum computing is coming soon. Therefore, I think we should all use anti-quantum methods.” Chaum said Bitcoin still has time before quantum computers pose a real threat to their password integrity. In addition, Chaum himself is advancing his own project, which is an anti-quantum signature blockchain that protects users from any metadata leakage. Chaum claims that its project white paper will be open to the public by the end of the year.
