原标题:吹牛成真?简要复盘Qubic双花攻击事件


一些后续:精彩,这是心理战啊。 自从上周 $XMR 被 Qubic 官宣 51% 攻击之后,社区事后复盘得出了几个结论:

1. Qubic 在上周所谓 51% 攻击时,并不真的拥有 51% 的算力,仅是短时内临时达到 35% 左右。

2. Qubic 连续出了 6 个 XMR 区块,疑似是自私挖矿。

所谓自私挖矿,就是自己挖到了区块,但是先憋着并不公布出来,等到攒到六个一口气出来变成最长链。这样让诚实矿工的 5 个区块(次长链)废掉,实现双花。

PS:我灵魂画手粗略画了个草图凑乎看。

其实,哪怕我只有 1% 的算力,我理论上也可以连挖 6 个区块,只不过概率太小,而 35% 算力概率就蛮大的。

我简单算了一下。这只是自然概率,按照门罗一天 1440 个区块,35% 算力数学期望每天就可以攻击成功 2.6 次。

这还没算自私挖矿的加成,算上就更高,否则 Qubic 未必舍得花钱短时间内租算力冲击 6 块。

为什么这种模式叫自私呢?是因为憋区块的话,为了保证成功率,里面往往不装交易,很多都是空块,浪费了区块空间。

说回正题,而且 Qubic 也没有双花,很多交易所 XMR 充值要 10 个区块确认,当然它是也没动力真的攻击。

所以你可以理解 Qubic 既没有 51% 算力,也没有 51% 攻击,只是浅浅秀了一下肌肉,然后发了宣传稿,号称完成了 51% 攻击。

但是为什么说它是心理战呢? 因为事件一出,很多矿工居然投降真的加入了 Qubic 矿池,导致截至昨天,Qubic 的算力一度真的超过了 50%。

所以这不是算力战,而是心理战。

这是某种对矿工的威慑—— 你不加入 Qubic 的矿池,那么你将来挖的区块就有可能作废掉,影响收成;加入了,虽然属于助纣为虐,非但损失,甚至还能双挖矿工也不全是骨头硬的,有很多还是要算经济账的。

紧接着,它们官宣了下一个目标就是狗狗币。不过我认为,狗狗币基于莱特币矿机,这个是有 Asic 的,未必那么简单,但是它们是玩心理战的高手。 所以这个官宣本身可能就是什么新的心理战。

叹为观止,这叫 Fake it till you make it,很难翻译,直译的话就是:“先假模假样吹起来直到吹着吹着牛逼变成了真的”。

Haiwei Huaxin's Official Seal Seized by Over a Hundred People, High-Stakes Corporate Battle's 'Nuclear Deterrence' in Action Again

On August 18th, Haowei Huaxin, a semiconductor firm specializing in gallium arsenide and gallium nitride wafers, reported that over a hundred individuals forcibly entered its offices and seized the company's official seals from a safe, including the corporate, contract, and party committee seals. The incident is the latest escalation in a protracted control dispute. Haowei Huaxin, established in 2010, was originally a joint venture. Control became contested after 2021 when Zhenwei Financial Holding injected capital, becoming the largest shareholder (34.01%), while former parent Haite High-Tech's stake was diluted to 33.79%. An agreed-upon governance structure collapsed, leading to mutual accusations. Haite claimed it was locked out of the subsidiary's premises, while also alleging improper management like livestock being kept on the chip fabrication site. After state-owned Qingdao Haiyue Holdings took over Zhenwei's stake in 2023, Haite accused it of illegally seizing control. Despite Haite winning several legal battles in 2024-2026, which affirmed its rights to nominate directors and the chairman, it failed to regain physical control or recover the seals. The stakes are high: market valuations for Haite's stake in Haowei Huaxin are estimated between 3.7 to 5 billion USD, yet it is only valued at about 83 million USD on Haite's books. Losing control effectively jeopardizes a significant portion of Haite's value. In response to the seal seizure, Haite framed it as a "shareholder rights protection" action agreed upon by five shareholders. This mirrors a pattern in Chinese corporate disputes where seizing physical seals becomes a tactic to paralyze the opponent's daily operations, seen in past conflicts at companies like Dangdang and Bitmain. However, such actions don't resolve underlying ownership issues; the opposing party can report the seals stolen, declare them void, and apply for new ones, albeit with significant delay. The incident underscores how fragile corporate governance can devolve into physical confrontations over symbols of authority, with control ultimately determined by law and shareholding, not possession of a seal.

Bernstein Interprets MRNA's 177% Surge: What's Fundamentals and What's Hype?

Bernstein's analysis of Moderna's 177% stock surge following positive Phase 3 results for its individualized neoantigen therapy (INT) in melanoma distinguishes fundamental drivers from market speculation. The clinical breakthrough is real: the INTerpath-001 trial met its primary and key secondary endpoints, providing crucial validation for mRNA technology in oncology beyond infectious diseases. However, Bernstein argues the magnitude of the stock move cannot be justified by this single trial's fundamentals alone. The surge was amplified by three key factors: 1) A re-rating of Moderna's mRNA platform potential for expansion into other cancers, 2) A massive short squeeze, given ~15% of shares were sold short pre-announcement, and 3) The compelling "cancer vaccine" narrative that fueled broader investor enthusiasm. While the melanoma success is significant, Bernstein cautions that replication in lung, kidney, and bladder cancers—which have different immunogenicity—is not guaranteed. Furthermore, INT's commercial model faces challenges: it's a personalized treatment, not a mass-market vaccine, implying higher production costs and potential margin pressures despite a projected multi-billion dollar peak sales opportunity. The report also notes sector rotation, with some funds moving from crowded AI/semiconductor trades into defensive healthcare stocks, adding further momentum. In conclusion, Bernstein maintains a "Market-Perform" rating and a $45 price target, far below the post-surge price. It views the current valuation as pricing in an optimistic multi-cancer platform success and efficient commercialization that are yet to be proven. The clinical inflection point is clear, but the earnings inflection point awaits validation across future trials and commercial execution.
