Warning for the Quantum Computing Era — 5 to 10 Years Needed for Large-Scale Bitcoin Upgrade

A new warning has been issued in the Bitcoin industry. Jameson Lopp, co-founder of the blockchain storage company Casa, has once again highlighted the long-term threats that quantum computing technology poses to Bitcoin. His insights go beyond mere technical concerns, shedding light on fundamental challenges that the entire industry must prepare for.

The Threat of Quantum Computing to Bitcoin

Lopp has been publicly discussing the potential risks that quantum computing could pose to the Bitcoin network for over 18 months. His conclusions are very straightforward: “I strongly hope that the development of quantum computing technology stalls or declines,” encapsulating the seriousness of the issue.

Why do these concerns arise? At the core is the reality that adapting the Bitcoin network to the post-quantum era is “extremely difficult for many reasons.” The technical and practical hurdles involved in significantly overhauling existing security systems are higher than many imagine.

However, regarding the immediate threat level, an optimistic outlook is currently maintained. Lopp points out that the likelihood of quantum computers breaking through the Bitcoin network in the near term is low, and it is important for the industry to continue monitoring technological developments.

Large-Scale Technical Overhaul Taking 5 to 10 Years

The most notable aspect of Lopp’s warning is his estimate of the time required for response. He indicates that a comprehensive review of the Bitcoin network and an unprecedented scale of fund and asset migration could take between 5 and 10 years.

This timeline does not merely refer to technological development; it encompasses the entire process of reaching consensus across the network, phased migration, and user adaptation—an extensive transformation that can only be achieved through industry-wide cooperation.

Proactive Measures as an Industry Challenge

In response to this situation, Lopp offers a balanced recommendation: “While hoping for the best, we should also prepare for the worst.” This means that although controlling the development of quantum computing technology is impossible, the Bitcoin industry must actively prepare for its advancement.

Currently, what is needed are in-depth technical research, the establishment of cross-industry review frameworks, and user education activities. Considering a long-term timeline of 5 to 10 years, a planned and phased approach will be key to maintaining the long-term stability of the Bitcoin ecosystem.
