Google’s New Quantum Research Reignites Push to Harden Bitcoin
A new research paper from Google has intensified debate over whether Bitcoin can adapt in time to withstand advances in quantum computing
Banking, traditional finance at risk as well
The issue also extends beyond cryptocurrency. The same class of cryptography secures banking systems, government communications and large parts of the internet.
In theory, the same cryptographic systems that secure Bitcoin also underpin global banking infrastructure, payment networks and government communications.
Google and cybersecurity agencies warned that attackers may already be collecting encrypted data today in anticipation of future quantum capabilities, a strategy known as “store now, decrypt later.”
Any viable quantum attack would not be isolated to crypto markets, but would extend across financial institutions and critical systems that rely on public-key encryption. Bitcoin is not uniquely vulnerable, but it is uniquely transparent. Its ledger makes exposure visible, and its open-source development model makes its response observable in real time.
Market reaction has remained muted so far, with prices largely unaffected by the latest research.
