G7 calls for immediate migration to post-quantum cryptography

The G7 Cybersecurity Working Group, chaired by France, has issued a joint statement titled ‘Preparing for the Post-Quantum Era: A Call to Action’. The document urges public authorities and companies to begin migrating to post-quantum cryptography immediately to ensure security against future quantum computing capabilities.

For Bitcoin holders, the transition involves assessing whether their addresses have exposed their public keys. Addresses that have never sent transactions do not reveal their keys, whereas addresses used for previous transactions show them permanently, potentially making them vulnerable to future quantum attacks. The G7 outlines five areas of action: raising awareness of quantum risks, developing national strategies, advancing research and adoption, strengthening government-industry cooperation, and integrating post-quantum methods into security requirements and procurement.
