The Protocol: Quantum computing could break Bitcoin sooner, says Google
CoinDesk
Google researchers suggest that quantum computers could compromise Bitcoin's security using fewer qubits than previously estimated, potentially accelerating the timeline for necessary cryptographic upgrades.Summary
Google's Quantum AI team has released a whitepaper suggesting that Bitcoin's security could be compromised by quantum computers more easily than previously anticipated. The research indicates that cracking Bitcoin's cryptography might require fewer than 500,000 physical qubits, with specific attack methods potentially needing only 1,200 to 1,450 high-quality qubits. The report highlights that Bitcoin's Taproot technology may inadvertently facilitate these vulnerabilities. As quantum technology advances, the findings raise urgent concerns about the timeline for migrating digital asset networks to post-quantum cryptography before current encryption methods become obsolete.
