Today’s operating landscape is full of pitfalls for businesses, particularly crypto-native ones. Companies that spent years building up bitcoin treasuries are now reportedly exiting the market, while on Wednesday (April 1) the Solana-based DeFi exchange Drift suffered an attack that drained $285 million in digital assets. And a new report from Google, titled “Safeguarding cryptocurrency by disclosing quantum vulnerabilities responsibly,” is only adding to the sector’s woes by highlighting the fact that quantum computing capable of breaking the cryptography underpinning bitcoin, ethereum and nearly the entire public chain ecosystem, is getting closer to reality. “We want to raise awareness on this issue and are providing the cryptocurrency community with recommendations to improve security and stability before this is possible, including transitioning blockchains to post-quantum cryptography (PQC), which is resistant to quantum attacks,” Google researchers wrote. The assertion cuts against the popular narrative that decentralized systems are inherently more resilient. Instead, Google’s analysis highlights a structural asymmetry: banks can quietly upgrade their cryptographic infrastructure, while public blockchains are bound by transparency, immutability and social consensus. Many systems rely on cryptographic primitives, especially elliptic curve signatures, that are theoretically vulnerable to sufficiently advanced quantum attacks. While those attacks remain impractical today, the exposure is already embedded in the chain.

Quantum risk is different because it is anticipatory. The threat of Q-Day, when it becomes both economically and technically feasible for quantum capabilities to reach and breach practical cryptographic relevance, has long been known about well before the
