However, with the different directions of "whether this research marks the practical application of quantum computing" and "will usher in the next wave of science and technology", the discussion on the coin ring pays more attention to the breakthrough of Google Coin and even blockchain in the field of financial security and the threat of "quantum hegemony". In fact, quantum threats, such as quantum computers, have a long history of subverting all current cryptography and destroying cryptocurrencies.
Since the birth of Bitcoin, people have mentioned and discussed Bitcoin many times. The powerful computing power of 20 17 quantum computer will crack the security of bitcoin within ten years. Faced with the concerns and doubts of most markets, many fields have given relevant explanations for many years. The method of "quantum hegemony" and the fear of cracking cryptographic systems are not unique to coinage.
At present, in addition to the Pacific Ocean, quantum chain and other cryptocurrency projects mainly based on quantum resistance, many experts in cryptography and quantum cryptography advocate establishing the problem of ensuring the safety of funds as soon as possible. According to William Tutton, a Bloomberg technology reporter, on Twitter last month, the National Security Agency has been working on related technologies. Therefore, unless the threat of quantum computing suddenly breaks out, Bitcoin still has time to deal with it. "Bitcoin is alive, * * * is there, and the currency is there. If you don't upgrade, it won't disappear because of algorithms or loopholes. But the problem of quantum resistance has not been solved. With the continuous development of quantum computers and the arrival of more qubit chips, this will still be the sword of Damocles hanging over cryptocurrency. "
