According to ChainCatcher, Cardano founder Charles Hoskinson has stated that the threat posed by quantum computing to blockchain technology is overstated and not an immediate concern. He emphasized that while the industry knows how to build quantum-resistant systems, these protocols are significantly slower and more costly, deterring networks from sacrificing throughput.
Hoskinson mentioned that until the National Institute of Standards and Technology (NIST) establishes post-quantum cryptography standards (FIPS 203-206), the industry cannot hastily adopt algorithms that might become obsolete. He referenced the U.S. Defense Advanced Research Projects Agency's (DARPA) Quantum Blockchain Initiative, which is assessing the feasibility of scalable practical quantum computers by 2033, with significant quantum challenges expected to emerge in the 2030s.
