Alex Thorn, head of research at Galaxy Digital, has highlighted the significant threat posed by quantum computing to Bitcoin and other cryptocurrencies. According to Thorn, existing solutions are even worse than people believe, posing a greater risk than anticipated. He emphasizes that public-key cryptography, essential for Bitcoin’s security, will be vulnerable to attacks from quantum computers. This vulnerability affects all crypto assets, not just Bitcoin. Thorn further warns that the timing of such an attack is unknown and could potentially pose a national security threat. The recent release of Microsoft’s Majorana 1 chip, which may revolutionize quantum computing, has re-ignited concerns about this risk. Notably, cypherpunk Jameson Lopp has called for destroying cryptocurrencies susceptible to quantum attacks. Further details can be found in the original article on U.Today.
