A Post Quantum Migration Proposal

The discussion initiated by Ethan Heilman revolves around the significant challenges posed by advancements in quantum computing to cryptographic security, particularly highlighting the vulnerability of cryptographic primitives to being compromised at a considerably lower cost due to these advancements. The crux of the matter lies in the unpredictability of the pace at which quantum computing might evolve, spurred by substantial investments in the field. This development stirs a legitimate concern within the community regarding protecting itself against potential security threats, acknowledging that the perspectives on addressing these concerns can both be valid.

Heilman further delves into the responsibilities of protocol developers towards Bitcoin holders, suggesting that developers may not have a fiduciary duty or any obligation to the users, especially since Bitcoin has not yet achieved the status of a unit of account. The fluctuating purchasing power of satoshis is underscored as a critical factor for the ecosystem's health and sustainability. Heilman posits that while developers might not actively need to intervene, the incentives for various groups within the Bitcoin community would naturally align with protective measures against such quantum threats.

The dialogue also touches upon the inherent human tendency to procrastinate, which could hinder the timely adoption of quantum-secure schemes. This procrastination, coupled with insufficient incentives, might lead to a scenario termed "Q-Day," potentially resulting in significant disruptions. Heilman points out the conflicting properties within Bitcoin, such as conservatism versus the necessity for upgrades to counter new challenges, including quantum computing advancements. This conflict could perpetuate ongoing disagreements between those resistant to changes (ossifiers) and proactive developers.

Lastly, Heilman contrasts two possible responses to the threat posed by quantum computing: a stoic acceptance of the threat under the belief that the system would inherently survive versus a proactive stance where the community collaborates to neutralize the threat before it causes extensive damage. He argues for the latter, implying that a collaborative effort to address and mitigate threats preemptively would instill greater confidence in the resilience of the system. This perspective eschews the idea of confiscating old coins as a solution, advocating instead for a more inclusive and preventative approach to securing the Bitcoin ecosystem against quantum computing threats.
