The founder of Cardano claims that the full deployment of quantum-resistant encryption is costly

According to Decrypt, Cardano founder Charles Hoskinson warned that quantum-resistant encryption schemes have been standardized by the U.S. National Institute of Standards and Technology (NIST) in 2024. However, without hardware acceleration support, their computational costs and data scales will significantly reduce blockchain throughput, potentially resulting in about an order of magnitude performance loss.

He pointed out that to assess whether the risks of quantum computing have reached a usable stage, more reference should be made to DARPA's quantum benchmarking program, which aims to evaluate the feasibility of practical quantum computing by 2033.
