Cardano founder says the quantum threat to cryptocurrency is overhyped

According to ME news, on December 9 (UTC+8), Cardano founder Charles Hoskinson stated that the threat of quantum computing to blockchain is exaggerated and not urgent at present. He pointed out that the industry already knows how to build quantum-resistant systems, but quantum-safe protocols run 10 times slower and cost 10 times more, and no network is willing to sacrifice throughput. Hoskinson said that before the US National Institute of Standards and Technology (NIST) establishes post-quantum cryptography standards (FIPS 203-206), the industry cannot rashly adopt algorithms that may be deprecated. He cited the US Defense Advanced Research Projects Agency (DARPA) Quantum Blockchain Initiative (QBI), saying the project is evaluating whether practical large-scale quantum computers can be achieved before 2033 and expects real quantum pressure to emerge in the 2030s.
