Could Quantum Computers Defeat Bitcoin? Not So Fast.
One of the most overlooked problems of blockchain systems is their ability to resist the fast-evolving machines known as quantum computers. These powerful computers use quantum physics to solve complex problems that are beyond the reach of traditional devices by using qubits—an evolution of the classic binary bit. Qubits are able to represent the value 1 or 0 at the same time, which promises to deliver an exponential increase of computing power. The world’s top superpowers are pouring billions o...
