Updated: Jan 06 2026- Quantum Threat Warning: David Duong, Coinbase's Global Head of Investment Research, warns that advancements in quantum computing could pose a structural risk to Bitcoin's long-term security, with approximately 32.7% of the circulating supply (around 6.51 million BTC) potentially vulnerable due to exposed public keys, prompting investors to reassess security strategies.
- Rising Regulatory Attention: As concerns about quantum computing are increasingly reflected in regulatory guidance and institutional disclosures, Duong emphasizes that the issue is shifting from theoretical to strategic, with U.S. and European agencies expected to mandate transitions to post-quantum cryptography by 2035 for critical infrastructure providers.
- Short-Range Attack Risks: Duong also highlights the risk of short-range attacks occurring when transactions enter the mempool, where public key exposure puts all outputs at risk, underscoring the urgency of migrating to quantum-resistant signature schemes to safeguard assets.
- Preparing for a New Security Regime: Although the probability of a successful quantum attack in the near term remains low, Duong stresses that early planning is essential given the long-term viability of cryptographic assumptions, ensuring Bitcoin's adaptability and security in the future.
