Samson Mow, CEO of JAN3, has advised against rushing Bitcoin's transition to post-quantum (PQ) security measures in response to potential quantum computing threats. Mow highlighted that premature adoption of PQ signature schemes could expose Bitcoin to classical computing attacks, as these signatures are significantly larger, potentially reducing network throughput and sparking scaling debates reminiscent of past block size controversies. Mow emphasized that quantum computing threats are a medium- to long-term concern, likely 10 to 20 years away, and advocated for continued research over hasty implementation. He also pointed out that Coinbase's wallet is vulnerable to quantum attacks due to address reuse, urging for infrastructure improvements to mitigate such risks.
