Earlier this week, Google gained "quantum hegemony" (presumably). This has caused a heated discussion about the world of cryptocurrencies (which can be imagined).
Cryptologists and cryptocurrent enthusiasts have had an endless debate about the impact of Google's quantum computers on bitcoin and other digital currencies. (The NASA file that was later deleted shows that Google's machines can complete calculations in seconds, while traditional machines take thousands of years to complete.)
David Chaum, who was hailed as the "father of passwords" for inventing the anonymous payment system e-Cash in the 1980s, did not stand idly by.
Yesterday, Chaum issued a statement on Google innovation, once again reiterating his position that the cryptocurrency world should develop anti-quantum technology from now on.
"We don't know how far other countries have gone in developing quantum computers. In the past, government agencies have been cracking passwords and have encryption capabilities for years, but no one knows."
"Google's news of quantum dominance makes me more convinced that quantum computing is coming, so I think we should all use anti-quantum methods."
Of course, even Bitcoin has a safe time before the quantum computer poses a real threat to its password integrity, but Chaum is pushing Praxxis to the fullest, which is a blockchain that uses anti-quantum fronts while protecting Users are not affected by any compromised metadata.
Chaum said that the Praxxis white paper will be released before the end of this year.
But he is not the only one who is worried about the quantum proof consensus algorithm.
Another project that is already underway is QAN. According to its project roadmap, the team claims to have achieved “quantum difficulty” in the beta testing phase.
QAN Chief Technology Officer Johann Polecsak said:
"It's best to make the worst plans for cryptography. We can observe in recent literature that past skeptics are now practicing their cryptographic protocols in post-quantum settings – just in case, Users should not worry now, but experts should be prepared in advance."
Polecsak and Chaum believe that it is time to prepare for the post-quantum world, and they are not alone.
Andrew Yang, the Democratic presidential candidate who is friendly to cryptocurrencies, is also paying attention to this. In fact, Yang has extensively discussed quantum computing and its potential threats to cryptography on his website.
Therefore, although Google’s “quantum first” theory may not have anything to be a little fussed, may it be better to pre-empt people than to regret it in the future?
