Blockstream CEO says public panic over quantum threats creates confusion, not preparedness
The debate over quantum computing risks to Bitcoin has intensified after Blockstream CEO Adam Back publicly criticized venture capitalist Nic Carter for amplifying what he called uninformed noise. The disagreement highlights a growing split within the Bitcoin ecosystem over how imminent and serious the quantum threat really is.
Rising Tensions Over Quantum Risk
Back responded sharply after Carter explained his firm’s investment in a startup focused on post-quantum security for Bitcoin. According to Back, the Bitcoin community is already researching safeguards but prefers to do so quietly and methodically, rather than through public alarm. He argued that speculative messaging can distort perception and potentially affect markets.
Carter disagreed, stating that many Bitcoin developers underestimate quantum computing risks. He emphasized that governments worldwide are already preparing for a post-quantum era and warned that Bitcoin’s cryptography could become a high-value target if quantum breakthroughs accelerate.
Opinions across the industry remain divided. Some analysts warn that quantum computers capable of breaking current cryptography could emerge within the next decade, urging Bitcoin to adopt quantum-resistant upgrades sooner rather than later. Others, including Back, maintain that the technology is still far too early-stage to pose an immediate danger.
Back has previously said that making Bitcoin quantum-ready is sensible long-term planning, but he stressed that practical quantum attacks remain decades away due to unresolved engineering challenges.
The discussion underscores a broader issue: how Bitcoin should balance responsible innovation with measured communication. While proactive research continues behind the scenes, leaders remain divided on whether public warnings accelerate readiness—or simply fuel unnecessary fear.
