Samson Mow Warns Rushed Post-Quantum Cryptography Fix Could Backfire for Bitcoin
Samson Mow says a rushed post-quantum cryptography upgrade for Bitcoin could introduce new vulnerabilities. He pushed back on Coinbase executives’ calls for faster preparation against future quantum computing threats.
Mow argues that post-quantum cryptography may protect Bitcoin from quantum computers, but implementing it too quickly could create compatibility problems and reduce network efficiency due to much larger signature sizes. He warns a “poorly timed transition” could leave Bitcoin weaker against today’s risks before it addresses future ones.
A key concern is performance: post-quantum cryptography signatures could be 10–125x larger than current ones, potentially cutting throughput dramatically. Mow links the likely impact on block size and transaction capacity to a renewed risk of “Blocksize Wars 2.0,” echoing past community splits over scaling and control.
Still, he says preparation work should continue. Mow notes quantum computers may not arrive for another 10–20 years, making “rushing the fix” the worst option. The debate was reignited by new research discussed alongside Google and Caltech’s findings.

这条新闻的直接交易含义偏中性。核心是“比特币后量子加密（post-quantum cryptography）升级不应仓促推进”。短期内，这可能降温市场对“立刻采取量子防御措施”的预期：若社区认为实施会引入签名膨胀、吞吐下降与潜在兼容性风险，可能削弱围绕量子叙事的买盘情绪，并强化对网络性能与治理分裂的担忧。
但它并非简单的“反量子”信息。莫明确表示准备工作仍应持续，且他认为量子计算机可能在10–20年内才可能形成真实威胁。这样的表态通常会让市场将该主题更多视为长期风险管理，而不是立刻需要的硬行动，从而减轻对立刻波动的推动。
对照历史，类似的“技术路线争议—性能权衡—治理分歧”往往会在短期带来叙事波动（例如过去的区块大小讨论引发社区拉扯与市场分歧），但只要没有明确的链上升级时间表，价格通常更受宏观流动性与整体风险偏好主导。长期来看，如果后量子加密确实带来吞吐压力，未来的扩容/架构选择可能影响比特币生态的竞争格局与投资者的长期预期。
