Bitcoin blocks usually take about 10 minutes to confirm. According to new research from Google, quantum key derivation might only take around 9 minutes. That similarity is hard to overlook. The main point isn’t that quantum computers will eventually break crypto—we’ve expected that. What matters now is that Google has reduced the estimated resources needed by about 20 times. That means fewer qubits, fewer gate operations, and shorter timelines. Plus, 1.7 million BTC are stored in old address formats where the public key is already visible. Attackers wouldn’t have to hurry; they could take as long as they want. 🔓 The crypto industry often sees upgrades like SegWit and Taproot as successes, and they are. However, Taproot brought back direct public key exposure for different reasons. Now, every design choice in crypto has a quantum aspect, whether teams realize it or not. ⏳ The threat isn’t immediate, but the time to prepare is now—and that window won’t last forever. 🏛️ If your organization holds digital assets, you should add post-quantum cryptography to your risk register now, not two years from now. https://www.ccn.com/education/crypto/google-quantum-computers-break-bitcoin-ethereum-9-minutes-1-7m-btc-risk/ #Cybersecurity #QuantumComputing #Crypto #RiskManagement #Blockchain
