- France’s ANSSI will stop certifying non-quantum-resistant security products starting in 2027.
- The U.S. NSA also mandates quantum-resistant algorithms for national security systems by the same year.
- Nearly 10% of Bitcoin’s supply is considered structurally unsafe from a quantum computing breakthrough.
- Cryptocurrency projects like Algorand, Aptos, Solana, and Ethereum have begun hardening their systems against quantum threats.
France’s national Cybersecurity agency, ANSSI, publicly announced at the France Quantum 2026 Summit that it will halt certifications for products lacking quantum-resistant encryption starting in 2027. This policy shift, reported by Reuters, mandates businesses to purchase only quantum-safe products by 2030. Consequently, vendors must demonstrate post-quantum cryptography capability by 2027 or lose access to lucrative government contracts.
“It’s not only a technical issue,” ANSSI chief of staff Samih Souissi stated. “It’s a matter of governance, industrial planning, regulation, and sovereignty.” This commitment aligns with the U.S. National Security Agency’s CNSA 2.0 suite, which requires all national security systems to use quantum-resistant algorithms by the same 2027 deadline. Therefore, two major global certification authorities have converged on an urgent timeline for post-quantum security.
Meanwhile, the cryptocurrency industry is grappling with the same quantum threat to its cryptographic foundations. Data from Glassnode estimated nearly 10% of the total Bitcoin supply, around 1.92 million BTC, is “structurally unsafe” from a quantum computing breakthrough. Coinbase also warned that proof-of-stake blockchains like Ethereum and Solana may be at greater risk.
However, many blockchain networks have already begun work to harden their systems. Coinbase noted Algorand has a staged roadmap and is among the first to deploy quantum-secure cryptography. It also said Aptos was well-positioned for the transition. Both Solana and Ethereum have created clear roadmaps to upgrade to quantum-resistant signatures.
