BlockBeats 消息，12 月 31 日，ElizaOS 创始人 Shaw 针对「量子计算威胁比特币」发表观点，它的实现比媒体当前报道的要遥远得多，对于 SHA-256 等哈希函数，Grover 算法仅将搜索空间从 2²⁵⁶减至 2¹²⁸，但 2¹²⁸仍不可能攻破。Shor 算法理论上可破解 RSA/ECDSA 加密，但当前量子计算机通常依赖于预处理或事先知道因素进行的优化，并非纯 Shor 算法的通用实现。想要破解比特币这个实时运行的网络，需要快速反复执行，如果可行，所有的加密数据都将暴露，到时比特币只是小问题。现代密码学从一开始就假设了未来的计算增长，二次加速也早在几十年前就被预期并被考虑在内。每当你看到围绕量子计算的恐惧或炒作时，请记住：这些人根本一无所知。
