Although a quantum attack threat is distant, experts advocate for immediate preparations.
According to Bitcoin exchange River, Microsoft’s latest quantum computing chip, Majorana 1, could accelerate the timeline for making Bitcoin resistant to quantum threats. While the risk of a quantum attack remains distant, experts warn that preparations must begin now. The chip, launched on 19 February, is part of a growing race in quantum technology, with Google’s Willow chip also making headlines in December.
River suggests that if quantum computers reach one million qubits by 2027-2029, they could crack Bitcoin addresses in long-range attacks. Though some argue such a scenario is still decades away, River insists early action is key. The potential threat has reignited discussions on BIP-360, a proposed upgrade to strengthen Bitcoin’s defences against future quantum advancements.
Critics remain sceptical, arguing that quantum computing is still in its infancy, with major technical challenges to overcome. Some believe traditional banking systems, which hold far greater assets than Bitcoin, would be targeted first. Others see quantum developments as an opportunity, suggesting they could help fortify Bitcoin’s security rather than weaken it.
