G7 Report Warns of Quantum Risks to Encryption
G7 Cybersecurity Working Group report of 3 September 2026 urges immediate post-quantum cryptography planning by governments and organizations.
The G7 Cybersecurity Working Group released a report on 3 September 2026 that identifies quantum-computing advances as a risk to existing public-key cryptography.
The report calls on governments and organizations to start migration planning to post-quantum cryptography without delay.
It notes that attackers may already be storing encrypted data for future decryption once capable quantum systems exist.
What remains unknown
No specific timelines, migration paths, or technical recommendations for Bitcoin or Ethereum are stated in the reported summary.
