Cardano Founder Claims 50% Chance of Quantum Threat by 2033; Bitcoin's Adam Back Dismisses Altcoin Concerns

Cardano founder Charles Hoskinson stated that there is more than a 50% chance that commercial-scale quantum systems capable of threatening current digital security will emerge by 2033. Hoskinson argued that sufficiently advanced quantum computers could decipher the mathematical structures protecting private keys and transaction signatures on blockchain networks, and called for the cryptocurrency sector to prepare now.

Hoskinson noted that Cardano is developing post-quantum security solutions using lattice-based cryptography and plans to integrate U.S. FIPS 203–206 standards. In response on X, Adam Back took a more cautious stance, stating: “Don’t listen to altcoin promoters. Bitcoin researchers are handling this. Altcoins mostly copy Bitcoin’s cryptographic libraries anyway, so they will most likely follow Bitcoin’s path.”
