Quantum Computing Threatens Bitcoin Security: Experts Urge Transition to Quantum-Safe Solutions
July 21, 2025
Quantum computers leverage qubits that can exist in multiple states, enabling them to perform calculations exponentially faster than classical computers, particularly for tasks like large number factorization.
Investors are advised to move their Bitcoin holdings to quantum-safe wallets and keep their software updated to mitigate emerging risks.
Currently, around 100 quantum systems are in operation globally, with forecasts suggesting this could rise to 5,000 by 2030, increasing the urgency of addressing quantum vulnerabilities.
Major financial institutions like BlackRock and Tether are beginning to recognize the quantum threat, acknowledging the potential impact on Bitcoin and other cryptocurrencies.
Monitoring developments such as error-corrected quantum processors and updates from organizations like NIST and the NSA is crucial as timelines for post-quantum cryptography evolve.
Tech giants like IBM, Google, and Microsoft are developing quantum processors with ambitious goals, some aiming for millions of qubits within the next decade, raising concerns about their potential to exploit blockchain vulnerabilities.
Governments and federal agencies are increasingly aware of the urgency to implement quantum-resistant algorithms, with U.S. agencies advising contractors to transition by 2035 amid rapid technological advancements.
Quantum computing poses an imminent threat to Bitcoin and blockchain security, with experts warning that current cryptographic foundations are outdated and vulnerable to future attacks.
David Carvalho, CEO of Naoris Protocol, emphasizes that adversaries are already employing a 'harvest now, decrypt later' strategy, collecting encrypted blockchain data for potential future decryption.
Carvalho, a former hacker turned cybersecurity expert, highlights that the cryptography underpinning current blockchains is susceptible to quantum attacks, especially as quantum systems rapidly advance.
To combat these threats, developers are working on quantum-safe solutions like quantum-resistant wallets and zero-knowledge proofs to protect users without sacrificing usability.
A phased approach is recommended for organizations and governments to adopt quantum-safe infrastructure, emphasizing collaboration and education to prevent fragmentation.
