G7 Cybersecurity Working Group urges post-quantum cryptography migration amid quantum risk
The G7 Cybersecurity Working Group on September 3 called on governments and businesses to begin transitioning to post-quantum cryptography immediately.
Why it matters
If cryptocurrency networks, exchanges and custodians are eventually required or pressured to migrate to post-quantum cryptography, the upgrades would involve significant cost and infrastructure coordination across the ecosystem. The report signals that regulators are treating quantum computing risk as an active policy concern rather than a distant theoretical problem.

What happened
The G7 Cybersecurity Working Group released a document titled 'Preparing for the Post-Quantum Era: A Call to Action' on September 3, 2026, urging governments and enterprises to begin transitioning to post-quantum cryptography. The working group warned that current public-key cryptography systems face future risk from quantum computing, and organizations should prepare before cryptographically viable machines arrive. The report does not specifically mention cryptocurrency, but Cryptopolitan noted the guidance is directly relevant to blockchain networks, exchanges, custodians and wallets that depend on the same public-key cryptography at risk. The near-term threat is not a quantum computer breaking Bitcoin imminently, but rather the governance, infrastructure and compatibility burden of migrating systems before quantum capabilities become real. No other outlets covered the story at the time of reporting.
