A new report from Google Quantum AI and Citi highlights the potential threat of quantum computing to cryptocurrencies, with Bitcoin being particularly vulnerable. The study found that Bitcoin's cryptography could be broken by a quantum computer using fewer resources than expected.
According to the research, this poses a significant risk for Bitcoin by 2026, potentially affecting investor confidence and institutional adoption. In contrast, Ethereum has been proactive in addressing this issue through its post-quantum upgrade roadmap.
Ethereum's flexibility in adapting to future quantum threats may give it an edge over Bitcoin in the long term. The Pectra upgrade is one of several initiatives aimed at implementing quantum-resistant cryptography by 2029.
