The post BlackRock Raises Alarm Over Bitcoin’s Quantum Threat appeared on BitcoinEthereumNews.com.

BlackRock, a global leader in investment management, has publicly voiced its concerns surrounding the potential threats that advances in quantum computing pose to Bitcoin. For the first time, the investment giant has recognized quantum technology as a potential danger to cryptocurrency in its official risk assessments, subsequently broadening its asset fund risk disclosures for investor awareness. How Might Quantum Technology Threaten Bitcoin? Quantum computing, once fully developed, could compromise Bitcoin’s security. BlackRock warns that existing cryptographic algorithms, which safeguard digital currencies and broader information systems, might become ineffective. This perspective was shared with the United States Securities and Exchange Commission in a formal report emphasizing that prevalent encryption methods utilized worldwide, including in Bitcoin, might face vulnerabilities. Can Bitcoin’s Security Adapt to Quantum Computers? Currently, the Bitcoin network remains unharmed by quantum computers, but imminent technological enhancements pose challenges to wallet and transaction security. The Elliptic Curve Digital Signature Algorithm (ECDSA), a pillar of Bitcoin’s security, stands firm against traditional computational methods. However, a sufficiently advanced quantum computer could potentially crack ECDSA using methods like Shor’s algorithm, leading to swift decryption, while Grover’s algorithm might significantly enhance mining efficiency. In light of these risks, the Bitcoin community is exploring a variety of solutions. A proposal by the developer Hunter Beast, known as the QuBit protocol, suggests an innovative address format to incorporate quantum-resistant digital signatures. This initiative could parallel strategies akin to the implementation of the Segregated Witness protocol. Other measures in exploration include developing post-quantum cryptography and enhancing blockchain technologies with quantum capabilities. Discussions for necessary updates to the Bitcoin network are also actively taking place, reflecting a comprehensive approach to fortifying security against quantum threats. Broader Industry Challenges Apart from quantum concerns, BlackRock’s documentation highlights various industry risks including regulatory ambiguities, environmental consequences of mining, regional mining power…
