[Coinbase Head of Research: About One-Third of Bitcoin May Face Quantum Attack Risks] BlockBeats News, January 6 – David Duong, Global Head of Investment Research at Coinbase, has warned that with the accelerated development of quantum computing technology, the long-term security of Bitcoin is entering 'uncharted waters.' He pointed out that the risks posed by quantum computing are significantly underestimated in the current $3.3 trillion crypto market. Duong stated that approximately one-third of Bitcoin's supply is at structural risk of quantum computing brute-forcing private keys in the future, as the public keys of these wallets have already been exposed. Although quantum computing is still in its early stages, the associated threats have evolved from theoretical concerns to real-world risks. He emphasized that compared to the potential impact of quantum computing on mining efficiency, the true core risk lies in the security of digital signatures. Once quantum computers achieve sufficient computational power, attackers could derive private keys from public keys and directly steal Bitcoin assets. Previously, institutions including BlackRock have explicitly listed quantum computing as a risk factor in Bitcoin ETF filings, and some researchers even predict that quantum computing could threaten Bitcoin's cryptographic system within 4–5 years.
