The cryptocurrency industry faces an accelerated quantum computing threat timeline, with Google research from March suggesting quantum computers may be able to break encryption by 2029, significantly earlier than previously expected. This represents a dramatic shift from previous estimates that placed quantum capabilities at least a decade away. The urgency stems from quantum computers' ability to solve complex mathematical problems much faster than conventional computers, potentially allowing them to unscramble conventional encryption methods that protect digital transactions and wallets. As reported by The Hindu BusinessLine, this threat is particularly concerning for the $2 trillion global cryptocurrency market that relies on blockchains secured by decades-old cryptography.
Bitcoin faces particularly acute quantum computing risks due to its extensive transaction history. Roughly 35% of the token's circulating supply could be exposed to quantum computing attacks, according to an unpublished June 2026 working paper by independent researcher Ahmed Raza Muhammad Umer, with other research estimating the figure could reach as high as 50%. The vulnerability stems from Bitcoin's 17-year history of transactions that have generated large numbers of visible public keys. As reported by The Hindu BusinessLine, just one incident involving stolen tokens could significantly impact the cryptocurrency's price, with Moody's analyst Cristiano Ventricelli noting that "everyone will feel the impact." The threat has already prompted reconsideration, with Jefferies' Christopher Wood removing a 10% bitcoin allocation from his model portfolio due to the long-term "existential" threat of quantum computing.
France has announced a comprehensive shift toward quantum-resistant security standards, with the cybersecurity agency ANSSI announcing at the France Quantum conference in Paris that it will stop certifying security products lacking quantum-resistant encryption from 2027. According to Reuters reports, Samih Souissi, ANSSI's chief of staff, stated that the agency will certify only quantum-resistant security products from 2027, with businesses advised to purchase only quantum-safe products by 2030. ANSSI certification serves as a gateway for sales into French government agencies and critical infrastructure, with the qualification process typically taking 12 to 18 months, creating a tight timeline for vendors starting now.
The cryptocurrency industry is beginning comprehensive defense preparations against the quantum threat. Some crypto companies and blockchain developers are already drawing up plans to upgrade their networks with quantum-resistant cryptography, though this represents a potentially years-long effort requiring sweeping infrastructure changes. As reported by The Hindu BusinessLine, Chris Tam of BTQ Technologies described quantum computing as "the most direct and existential threat towards cryptocurrencies and crypto networks." The problem is particularly complex for blockchains due to their decentralized nature, with none of the top 20 blockchains having implemented a post-quantum signature algorithm. The Ethereum Foundation is targeting 2029 for full protection from quantum computing, while the Algorand Foundation plans to start supporting post-quantum accounts later this year.
WISeKey International Holding Ltd. has demonstrated strong financial performance with full year revenue of CHF 19.3 million in 2025, representing a 62% increase from CHF 11.9 million in 2024. The company's subsidiary SEALSQ contributed CHF 18.3 million with 66% growth, while Q4 revenue reached CHF 8 million, doubling from CHF 4 million in Q4 2024. According to the company's earnings call, approximately CHF 3.5 million of the full year increase relates to five months of revenue contribution from IC'Alps, which was acquired through SEALSQ on August 4, 2025. The company maintains a strong balance sheet with over CHF 429 million in cash and short-term investments as of December 31, 2025, growing to more than CHF 535 million as of April 30 following a CHF 125 million capital raise for SEALSQ in March 2026.
