Quantum computing is here, although it’s far away from making it into the mainstream. To make a long story short, it will revolutionize computer hardware and be a lot faster than traditional machines. This will pose a problem for bitcoin and other blockchain projects, because they rely on math problems that normal computers have difficulty solving, including for key encryption.
I recently had the opportunity to sit on a panel with Gavin Brennen of Macquarie University in Sydney, Australia, a physicist and one of the world experts on this topic. He presented a very nice paper that examined the perceived danger in some detail.
