周五,当全球电脑屏幕变蓝时,航班停飞,酒店无法办理入住手续,货运也停滞不前。企业求助于纸和笔。最初的怀疑是某种网络恐怖袭击。然而,现实情况要平凡得多:网络安全公司CrowdStrike的一次拙劣的软件更新。安全公司Blackpoint Cyber的威胁情报总监尼克·凯悦表示:“在这种情况下,这是一次内容更新。”。由于CrowdStrike拥有如此广泛的客户群,这是全球范围内的内容更新。凯悦说:“一个错误造成了灾难性的后果。这是一个很好的例子,说明我们的现代社会与IT有多么紧密地联系在一起——从咖啡馆到医院再到机场,这样的错误会产生巨大的影响。”。在这种情况下,内容更新与CrowdStrike Falcon监控软件相关联。Hyatt说,Falcon与监控端点(在这种情况下是笔记本电脑、台式机和服务器)上的恶意软件和其他恶意行为有着深厚的联系。Falcon会自动更新以应对新的威胁。凯悦说:“Bug代码是通过自动更新功能推出的,好吧,我们到了。”。自动更新功能是许多软件应用程序的标准配置,并非CrowdStrike独有。凯悦补充道:“只是由于CrowdStrike的所作所为,这里的后果是灾难性的。”。
尽管CrowdStrike很快发现了这个问题,许多系统在几个小时内就恢复并运行了,但对于拥有复杂系统的组织来说,这种全球性的连锁反应并不容易逆转。前联邦调查局反恐和反情报人员、网络安全专家埃里克·奥尼尔说:“我们认为,在事情解决之前,需要三到五天的时间。”。“这对组织来说是一堆停机时间。”奥尼尔说,停机发生在一个夏季的周五,许多办公室都是空的,It部门帮助解决了供应短缺的问题,这并没有帮助。O'Neill说,从全球IT中断中吸取的一个教训是,CrowdStrike的更新应该逐步推出。奥尼尔说:“Crowdstrike正在做的是一次向所有人发布更新。这不是最好的主意。把它发给一个小组进行测试。它应该经过一定程度的质量控制。”。Visual Edge It安全与合规副总裁Peter Avery表示:“在推出之前,它应该在沙箱中的许多环境中进行测试。”他预计需要更多的保护措施来防止未来再次发生此类故障。Avery说:“你需要在公司中进行正确的制衡。可能是一个人决定推动这一更新,也可能是有人选择了错误的文件来执行。”。IT行业称之为单点故障——系统某一部分的错误,在行业、功能和互联通信网络中造成技术灾难;巨大的多米诺骨牌效应。呼吁在IT系统中建立冗余
Cohesity首席执行官在谈到全球技术中断时表示:“我们需要让这些系统‘更有弹性’。”
周五的活动可能会促使公司和个人提高网络准备水平。Avery说:“从更大的角度来看,世界是多么脆弱;这不仅仅是一个网络或技术问题。有很多不同的现象会导致停电,比如太阳耀斑会破坏我们的通信和电子设备。”。约翰·霍普金斯大学凯里商学院信息系统助理教授Javed Abed表示,最终,周五的崩溃不是对Crowdstrike或微软的控诉,而是对企业如何看待网络安全的控诉。Abed表示:“企业主不应再将网络安全服务仅仅视为一种成本,而应将其视为对公司未来的重要投资。”。企业应该通过在系统中建立冗余来做到这一点。阿贝德说:“单点失败不应该阻止一家企业,事实就是这样。”。Abed说:“你不能只依赖一种网络安全工具,即网络安全101。”。虽然在企业系统中建立冗余是昂贵的,但周五发生的事情更昂贵。Abed说:“我希望这是一个警钟,我希望它能改变企业主和组织修改网络安全战略的心态。”。如何处理“内核级”代码纽约大学SPS全球事务中心前国土安全部官员兼讲师Nicholas Reese表示,在宏观层面上,在企业it世界中分配一些系统性责任是公平的,因为企业it通常将网络安全、数据安全和技术供应链视为“有东西就好”而不是必需品,组织内部普遍缺乏网络安全领导力。Reese说,在微观层面上,导致这种中断的代码是内核级代码,影响着每一个计算机硬件和软件通信方面。Reese说:“内核级代码应该得到最高级别的审查。”批准和实施需要是完全独立的流程,并具有问责制。这是一个将持续存在于整个生态系统的问题,充斥着第三方供应商的产品,都有漏洞。里斯说:“我们如何纵观第三方供应商的生态系统,看看下一个漏洞会在哪里?这几乎是不可能的,但我们必须尝试。”。他说:“在我们努力应对潜在漏洞的数量之前,这不是一个可能,而是一个必然。我们需要专注于备份和冗余,并对其进行投资,但企业表示,他们负担不起可能永远不会发生的事情的费用。这是一个很难证明的案例。”

Gold Price Achieves Strongest Rally in 46 Years, Tokenized Gold Trading Volume Already Exceeds Full-Year 2025

Gold is experiencing its strongest rally since 1979, with prices reaching a record high near $5,600 per ounce in January. This surge is driven primarily by central banks, not retail investors. In 2025, central banks net purchased 863 tonnes of gold, with a similar increase expected in 2026. Traditional gold investment methods—physical bullion and ETFs—present trade-offs like storage issues, limited access, or management fees. Tokenized gold emerges as a third option: digital tokens representing ownership of physical bars stored in professional vaults. These tokens are globally transferable in seconds, divisible, and redeemable for physical metal. The potential impact mirrors that of dollar stablecoins. Stablecoins digitized the dollar, enabling cheap, instant, global transfers and driving adoption from $27 billion in 2020 to over $3 trillion today. Similarly, tokenized gold solves gold's "form problem"—its lack of divisibility, portability, and accessibility. Adoption is accelerating. In Q1 2026, tokenized gold trading volume hit $90.7 billion, surpassing the $84.6 billion for all of 2025. Its market cap exceeded $6 billion, growing 5.5 times faster than physical gold holdings in the quarter. While concerns about counterparty risk exist, tokenized gold represents a direct claim on allocated bars, with major issuers providing regular attestation reports. Just as stablecoins placed dollars on a digital, global rail, tokenized gold now offers a more practical form for this ancient asset, potentially expanding access to billions.

Japanese Rates Return to 1996 Levels, Can Bitcoin Withstand the September Rate Hike?

Japanese borrowing costs have hit their highest levels since 1996, with yields on 30-year bonds reaching 4.185%. This marks a significant shift for a country long reliant on negative rates. Concurrently, Bitcoin surged 22% past $80,000, seemingly decoupled from the bond market turmoil. Historically, the massive yen carry trade has fueled global risk assets, predicated on near-zero Japanese rates. This assumption is now challenged. A potential rate hike by the Bank of Japan in September could strengthen the yen, forcing carry trade unwinds and potentially triggering a global deleveraging event, as seen in August 2024 when Bitcoin fell sharply. Conversely, if the yen weakens further, Bitcoin could attract Japanese investors as a hedge against currency depreciation and the country's massive debt burden. Institutional adoption in Japan is growing, with regulatory changes paving the way for potential crypto ETFs by 2027. The key variable is the BoJ's September policy signal. If it hints at a rapid tightening cycle to combat inflation and support the yen, risk assets like Bitcoin may face selling pressure from carry trade liquidation. However, if debt sustainability concerns limit its hawkishness, leading to a weaker yen, Bitcoin could benefit. Currently, the market is betting on a slow-motion debt crisis, not a sudden collapse. While Bitcoin shows resilience, its fate remains tied to the direction of the yen and the scale of any carry trade unwind.

How Can Bitcoin Resist Quantum Computers? A Comparison of Three Lattice-Based Signature Schemes

"Bitcoin's Quantum Defense: A Comparison of Three Lattice-Based Signature Schemes" by the Blockstream Research Team explores how Bitcoin can transition to quantum-resistant digital signatures, as current schemes like Schnorr and ECDSA are vulnerable to quantum computers. The report evaluates three lattice-based signature candidates—Dilithium, Falcon, and Hawk—against criteria like on-chain cost (key/signature size), implementation complexity, deployment risks, and support for Bitcoin's key derivation standard (BIP-32). The analysis recommends a minimum Security Level 3 for Bitcoin due to its long-term security needs. Dilithium (ML-DSA) is praised for its simplicity and integer-only operations, making it easier to implement securely, but it has the largest signature size (~5.3 KB for Level 3). Falcon (FN-DSA) offers the most compact signatures (e.g., ~3.1 KB for Level 5) and the fastest verification, though its signing requires complex floating-point sampling—a solvable engineering challenge. Hawk, despite its small size, was withdrawn from NIST standardization after a security vulnerability was discovered, highlighting the importance of conservative security margins. Currently, neither Dilithium nor Falcon has a fully viable, production-ready BIP-32 key derivation method. The report concludes that if a lattice-based scheme had to be chosen now, Falcon-1024 would be the preferred option for its balance of size, speed, and mature security assumptions. However, the short-term recommendation remains hash-based signatures (like SPHINCS+) for their lower risk, with a potential future hybrid or full transition to Falcon once its standard (FN-DSA) is finalized and well-supported.
