France to Phase Out Non-Quantum Encryption by 2027: What It Means for Bitcoin and Crypto

France is taking a decisive step toward a quantum-safe future. The country’s national cybersecurity agency, ANSSI, announced it will stop certifying security products that lack quantum-resistant encryption starting in 2027. The move has major implications for the entire tech industry — and the cryptocurrency ecosystem in particular.

🔐 What ANSSI Announced at the France Quantum 2026 Summit

Speaking at the France Quantum 2026 Summit, ANSSI chief of staff Samih Souissi revealed the agency’s timeline: starting in 2027, ANSSI will no longer certify products that do not incorporate post-quantum cryptography (PQC). By 2030, businesses should purchase exclusively « quantum-safe » products.

This announcement was not unexpected for industry insiders. « ANSSI has been telegraphing this move for years, » said Marin Ivezic, founder of consulting firm Applied Quantum, in a LinkedIn post. « What changed yesterday is that ANSSI’s chief of staff said publicly that the date is now firm. »

ANSSI certification is a critical prerequisite for use across French government agencies and critical infrastructure operators. The move effectively forces vendors to demonstrate post-quantum cryptography capabilities if they want to continue working with the French state.

« It’s not only a technical issue, » Souissi said. « It’s a matter of governance, industrial planning, regulation, and sovereignty. »

🌍 A Global Movement: France and the U.S. Converge on the Same Timeline

France’s decision aligns remarkably closely with U.S. policy. The National Security Agency (NSA) already requires all national security systems to use its CNSA 2.0 suite of quantum-resistant algorithms by 2027.

Under CNSA 2.0, all new national security system acquisitions must support the approved algorithms by January 1, 2027. Noncompliant systems must be phased out by the end of 2030, and by 2033, the entire installed base must be fully migrated.

« Two of the world’s most demanding cryptographic certification authorities, serving two of the world’s largest defense and government technology markets, have independently converged on the same year: 2027, » Ivezic noted. « This is not a coincidence. »

⚠️ Why This Matters for Bitcoin and Cryptocurrencies

The quantum threat is being taken very seriously in the crypto industry — and the numbers are staggering.

According to on-chain analytics platform Glassnode, nearly 10% of Bitcoin’s total supply — approximately 1.92 million BTC (over $120 billion at current prices) — is considered « structurally unsafe » in the event of a quantum computing attack. These are primarily coins held in addresses using older, vulnerable signature formats (P2PK).

In April, Coinbase warned that Proof-of-Stake (PoS) blockchains, including Ethereum and Solana, may face even greater risk from quantum computing because of the signature schemes validators use to secure their networks.

Which Blockchains Are Preparing?

Coinbase also acknowledged that many blockchains have already started hardening their systems:

• Algorand has a « staged roadmap toward full quantum readiness » and is among the first networks to deploy cryptography designed to be secure against quantum computers.
• Aptos is « well-positioned for the transition to post-quantum secure transactions. »
• Solana and Ethereum have created clear roadmaps to address quantum threats, including upgrading signature schemes to be quantum-resistant.

Researchers estimate that quantum computers could, in theory, be operational by 2030 — exactly the timeline set by both ANSSI and the NSA.

🎯 The Bottom Line

ANSSI’s decision is a powerful signal for the entire technology and financial industries. It serves as a stark reminder that the quantum threat is no longer science fiction — it’s a concrete risk materializing on a 2027-2030 horizon.

For the crypto ecosystem, this is both a warning and an opportunity. Projects that anticipate and integrate post-quantum cryptography now will be the big winners of the decade. Those that delay risk becoming technically obsolete — and leaving their users exposed.

ANSSI’s message is clear: prepare now, or be excluded from the market. It’s a lesson the crypto industry would be wise to heed.
