ChainCatcher 消息，JAN3 首席执行官 Samson Mow 在 X 平台发文表示，当前围绕比特币量子计算（QC）威胁的应对不应操之过急，如果盲目仓促从现有签名机制切换至抗量子（PQ）方案，反而可能使比特币在短期内暴露于传统计算攻击（classical computing attacks ）风险，PQ 签名体积可能扩大 10 至 125 倍，将显著降低网络吞吐量，甚至可能引发类似早年“区块战争”的扩容争议重演。
此外，Samson Mow 警告部分 PQ 方案或存在潜在后门风险。量子计算威胁仍处于中长期阶段（或需 10 至 20 年），当前更合理路径是持续研究而非仓促部署，同时还点名 Coinbase，称其钱包因地址复用存在量子攻击隐患，建议优先修复相关基础设施问题。
