Cardano’s Hoskinson Warns Crypto Becoming Post-Quantum Will Require Trade-Offs
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, pointing to post-quantum standards released by the U.S. National Institute of Standards and Technology in 2024. The problem Hoskinson explained is what it would cost if the new protocols are implemented before miners and validators are ready.
“Post-quantum crypto oftentimes it’s about 10 times slower, 10 times larger proof sizes, and 10…
