Adam Back Responds to Nic Carter's Quantum Threat Concerns in Bitcoin
Bitcoin experts are divided over the timeline of quantum computing risks to the cryptocurrency’s security. Some warn that threats could emerge within years, while others believe the danger remains decades away. The debate highlights differing views on how urgently the network must adopt quantum-resistant measures.
Nic Carter has raised concerns about quantum computing’s potential to break Bitcoin’s cryptographic defences. His worries led him to invest in Project Eleven, a startup focused on quantum-resistant technology. He argues that the risk could become real sooner than many expect.
Charles Edwards shares a similar urgency, suggesting that quantum threats might materialise in two to nine years if Bitcoin does not upgrade its security. His warning contrasts sharply with the views of others in the field. Adam Back, however, disputes these claims. He insists that Bitcoin is still decades away from facing a serious quantum threat. While he acknowledges the need for the network to be 'quantum ready,' he believes the community is already working on solutions behind the scenes. Back also argues that public discussion of the issue has been unnecessarily alarmist. Kevin O’Leary offers a different perspective, stating that quantum computing would not be the most practical way to attack blockchain systems. His comments suggest that other vulnerabilities might pose a greater immediate risk.
The lack of consensus among experts means no clear timeline exists for when quantum risks could become critical. No widely recognised specialists have publicly outlined specific plans to address the issue. For now, Bitcoin’s approach to quantum resistance remains a topic of debate rather than action.
