的采访，后者称，投资者应警惕量子计算在未来 3 至 4 年内对现代密码学构成挑战。Cramer 认为，量子计算可能在相近时间内威胁比特币网络。不过，目前尚无人独立确认其持有多少 BTC，或其是否已经完成出售。其表态后，比特币仍在 63,764 美元附近正常交易，部分市场参与者则再次将其观点视为“反向 Cramer”信号。比特币使用基于 secp256k1 曲线的 ECDSA 签名机制，理论上，足够强大的量子计算机可利用 Shor 算法从公钥推导私钥。风险主要集中在已暴露公钥的地址，包括重复使用地址、早期钱包格式，以及交易广播后尚未确认的短暂时间窗口。研究人员估计，约 600 万至 700 万枚 BTC、占供应量约 30%，可能处于该类别。Google Quantum AI 今年 3 月估计，破解相关密码机制可能需要少于 50 万个物理量子比特，较此前预测降低约 20 倍。但当前量子系统通常仅拥有数百至数千个物理量子比特，具备更高可靠性的逻辑量子比特数量更少。多数研究人员预计，真正具备密码破解能力的量子计算机可能要到 2030 年代甚至 2040 年代出现，因此 Cramer 的 3 年预测明显早于多数技术预期。

年内因量子计算而消失。他称，一旦量子计算机能够快速解决保护比特币私钥的数学问题，“那将是比特币的终结”。\n\n不过，McAlvany 随后承认，自己无法确定相关突破究竟会在 4 年、5 年后，还是两个月后出现。截至 2026 年中，尚不存在能够破解比特币加密算法的量子计算机。其观点主要基于对量子计算未来发展速度的担忧，而非已经发生的安全事件。\n\nGalaxy Digital 估计，约 700 万枚 BTC 所在地址已在链上暴露公钥，价值约 4700 亿美元；Glassnode 的估计为 604 万枚，占比特币供应量的 30.2%。公钥暴露并不等同于资产已被盗，只有当量子计算机能够根据公钥反推出私钥后，这些地址才可能面临实际盗取风险。\n\nMcAlvany 还将比特币与黄金进行比较，并质疑比特币能否持续存在 5000 年。他表示，自己相对确信黄金届时仍会存在，但比特币“可能存在，也可能不存在”。\n\n比特币开发者目前对解决方案存在分歧。BIP-360 提议增加抗量子地址类型；BIP-361 则计划分阶段停止支持旧式签名，未及时迁移的资产可能被永久冻结，其中包括被认为属于中本聪的比特币。支持者认为，冻结资产优于让量子攻击者盗取并抛售，批评者则将其视为没收。\n\nBOLTS Technologies、American Fortress 等公司也在开发跨链抗量子方案。American Fortress 于 5 月完成 800 万美元种子轮融资，并声称其技术无需用户迁移地址即可保护资产，但相关技术论文尚未公布，设计也未接受公开审计。
