Quantum Risk Is Real—But It’s a 2030s Problem, Not a 2020s Panic

Despite growing speculation, Hoskinson insists quantum computing isn’t close to breaking modern blockchain cryptography. Researchers broadly agree, treating CRQC-level machines as a 2030s-era threat, not an imminent one.
He pointed to DARPA’s Quantum Blockchain Initiative (QBI), which is evaluating whether practical, large-scale quantum computers could exist by 2033. That program, he says, is the clearest benchmark for tracking meaningful progress. Until then, quantum-secure migration will be driven by planning and hardware readiness — not emergency action.

Exactly—threat is real but not immediate.

Plenty of time to prepare before quantum becomes practical.
