Google's Quantum Warning Starts Repricing Crypto Security

Post-quantum tokens jumped after new Google research cut the estimated resources needed to break elliptic-curve cryptography, sharpening pressure on older chains to prepare.

Traders pushed into post-quantum crypto names after Google published new research suggesting the encryption that protects bitcoin and many other chains may be easier to crack than earlier estimates assumed. CoinDesk reported that Quantum Resistant Ledger and Cellframe each jumped about 50% over the past day, while bitcoin and ether barely moved.

The move followed Google's March 31 warning that a future machine with fewer than 500,000 physical qubits could break the elliptic-curve cryptography used across crypto in a few minutes under the company's hardware assumptions. Google said that machine does not exist now, but it tied the disclosure to a 2029 transition timeline and urged the industry to start migrating toward post-quantum defenses.
