Quantum Computing

Jim Cramer says he plans to sell all of his bitcoin because of concerns that quantum computing could threaten crypto security within three to four years. Bitcoin has remained resilient near $64,000, with many traders treating the warning as another contrarian signal.

Solana Foundation CISO Michael Coates says crypto’s next major security challenge is shifting from code exploits toward AI-powered social engineering, fake identities and compromised credentials. The foundation is also evaluating post-quantum cryptography as blockchain networks prepare for longer-term risks from quantum computing.

Hong Kong’s banking sector received a Quantum Preparedness Index score of 2.3 out of 10 from the Hong Kong Monetary Authority. The regulator is pushing banks toward stronger post-quantum cryptography planning, pilots and practical preparedness by 2030.

Quantum computing is moving from distant theory toward a practical risk for encrypted systems, and Bitcoin may be among the first major networks tested. Market experts say the largest challenge may not be cryptography itself, but whether decentralized governance can move quickly enough to deploy post-quantum protections.

Galaxy Digital has launched a $5 million initiative aimed at helping Bitcoin developers prepare for future quantum-computing threats. The program will fund work on quantum-resistant signatures, wallet migration tools and security audits as the industry weighs long-term risks to blockchain cryptography.

Project Eleven says a new zero-knowledge proof system could let wallet owners prove control of quantum-vulnerable bitcoin without exposing seed material. The approach may support a recovery path under BIP-361, but it does not cover Satoshi-era coins generated before modern wallet derivation existed.

A proposal from Binance founder Changpeng Zhao to freeze Satoshi Nakamoto’s estimated 1.1 million bitcoin if quantum computers threaten Bitcoin’s cryptography has divided prominent industry figures. The dispute centers on whether defending the network from a future hack would justify intervention in coins long treated by markets as permanently dormant.

The White House has issued twin executive orders to accelerate U.S. quantum computing efforts while preparing federal systems for a future where today’s encryption may no longer be safe. One directive pushes advanced hardware and sensors, while the other forces a shift to post-quantum cryptography.

The Algorand Foundation has unveiled a plan to harden its network against future quantum threats, with user-facing upgrades slated to begin in 2026. The roadmap reflects a broader industry push to prepare blockchain infrastructure for post-quantum cryptography.
