Bernstein: Quantum Computers Are Not an Immediate Threat to Bitcoin Security

Wall Street research firm Bernstein states that the development of quantum computers is not an imminent crisis for the Bitcoin network (08/04). In its latest report, Bernstein acknowledges that future quantum computers pose a technical challenge to digital asset cryptography, but this is not categorized as an emergency. Analysts estimate that the industry has between three to five years to implement post-quantum security systems.
This report responds to Google research suggesting that future quantum machines could potentially break Bitcoin transaction signature encryption with fewer resources. However, Bernstein emphasizes that achieving a real attack would require major breakthroughs in hardware and cost-efficiency that are not yet solved. Therefore, quantum challenges are viewed more as an evolution of scheduled protocols rather than an abrupt crisis for the market.
Bernstein also highlights the involvement of major institutions like BlackRock and Fidelity, which have an interest in strengthening network security standards. Currently, the developer community has prepared preventive measures through proposals like BIP 360 to reduce vulnerability to quantum attacks. With the cryptography migration targeted for 2029, market stability is expected to remain intact as new security technologies are adopted across the industry.
