Quantum Risk Is a Long-Term Upgrade Challenge—not a Wallet Panic
Quantum computers are not cracking crypto wallets today—but preparation has a long lead time.
Google Research’s March 31, 2026 paper estimates that a future cryptographically relevant quantum computer could run Shor’s algorithm against 256-bit elliptic-curve cryptography with fewer than 1,200 logical qubits in one circuit. These are error-corrected logical qubits, not a working machine available today. The result is a resource estimate, not evidence that current wallets are compromised. Google recommends that blockchains plan for post-quantum cryptography before such hardware exists. What migration steps should networks prioritize first?
