Bitcoin Quantum Risk: Jameson Lopp Warns Post-Quantum Overhaul Could Take 5 to 10 Years

COINOTAG News reports that Jameson Lopp, co-founder of Casa, has spent 18 months publicly outlining quantum computing risks to Bitcoin. He argues the shift to a post-quantum era would demand a highly technical retooling, with multiple structural and governance considerations to address.

He notes that quantum computers are unlikely to break the network in the near term, but a comprehensive network overhaul and unprecedented fund migration could unfold over a five-to-ten year window. The framing is cautious optimism: ongoing monitoring paired with deliberate contingency planning.

For market participants and custodians, the takeaway is to bake risk management and post-quantum readiness into investment theses and security architectures, ensuring resilience as the ecosystem evolves toward a potential post-quantum era.
