【慢雾余弦：Qubic控制门罗币算力比例仍存疑，且不易于求证】金色财经报道，慢雾创始人余弦评价门罗币遭 51% 攻击事件表示，社区对到底是不是真正意义上的 51% 攻击存在不少质疑，但对重组区块（比如 6 个）没有质疑。Qubic 矿池自称控制 51% 算力，但不少社区成员认为大约控制 33% 算力。该争论并不容易求证，要实锤 51% 只能发起双花攻击测试。 此前报道，IOTA 联创 Sergey Ivancheglo 的项目 Qubic 通过“有用工作量证明（uPoW）”机制，迅速积累大量门罗币（Monero）算力，8 月 12 日，Qubic 短暂控制了门罗网络 52.72% 的哈希率（约 3.01 GH/s）。一旦超过 51%，Qubic 可以拒绝其他矿池的区块，导致链重组、双花或交易审查。门罗社区已展开抵制和防御行动，Qubic 方面称此举为技术演示，非恶意攻击。
