In brief
- Charles Hoskinson said quantum-resistant cryptography is already standardized, but remains too slow for widespread use.
- He pointed to DARPA’s quantum benchmarking program as a key reference for when cryptographic risk becomes practical.
- Hoskinson said Cardano is exploring staged mitigations while waiting for hardware acceleration to mature.
As blockchain developers debate protocol updates to counter possible future quantum attacks, Cardano founder Charles Hoskinson said the central issue is timing and not what changes to make, warning that moving too soon could carry a high cost for blockchain networks.
According to Hoskinson, the cryptographic tools needed to protect blockchains from future quantum attacks already exist,…
