Cardano's founder stated that fully deploying quantum-resistant encryption is extremely costly.

According to a report by Decrypt, Cardano founder Charles Hoskinson warned that while quantum-resistant encryption schemes were standardized by the National Institute of Standards and Technology (NIST) in 2024, their computational cost and data scale will significantly reduce blockchain throughput in the absence of hardware acceleration support, potentially resulting in a performance loss of about an order of magnitude. He pointed out that to determine whether quantum computing has reached a usable stage, more attention should be paid to DARPA's quantum benchmarking program, which plans to assess the feasibility of practical quantum computing by 2033.
