Ishares比特币信托（IBIT）招股说明书中的贝莱德旗量子计算风险

本周，围绕量子计算和比特币的辩论在加密球体内重新点燃，对领先的数字资产背后的网络是否最终可能面临脆弱性的猜测。

Freshly revised paperwork for BlackRock’s Ishares Bitcoin Trust (IBIT) now includes a cautionary note that the advent of powerful quantum computing—and related developments—could render Bitcoin’s foundational cryptographic safeguards “becoming ineffective.”

贝莱德（BlackRock）的iShares比特币信托基金（IBIT）的新鲜修订的文书工作现在包括一个警示指出，强大的量子计算的出现以及相关的发展可能会使比特币的基础加密保护措施“变得无效”。

This week saw the topic of quantum computing and Bitcoin return to the forefront within the cryptocurrency sphere, sparking renewed speculation over whether the network underpinning the leading digital asset could eventually face vulnerabilities. The discussion was triggered by a new study posted on arxiv.org detailing a method for factoring 2048-bit RSA integers using fewer than a million imperfect qubits.

本周，量子计算和比特币的话题恢复了加密货币领域内的最前沿，引发了人们对领先数字资产基础的网络是否最终可能面临脆弱性的重新猜测。讨论是由在arxiv.org上发布的一项新研究触发的，详细介绍了一种使用少于一百万个不完美量子的方法来考虑2048位RSA整数的方法。

The study, titled "Factoring 2048-bit RSA Integers in 800,000 Imperfect Qubits," presents a blueprint for breaking RSA-2048 in about seven hours using a quantum computer with 800,000 imperfect qubits and performing a single round of modular addition in about 300 time steps. This approach can be applied to any intermediate RSA size and is relevant to cryptocurrencies such as Bitcoin, which use 256-bit elliptic curves.

该研究的标题为“在800,000个不完美的Qubits中分解2048位RSA整数”，它提出了一种蓝图，用于使用800,000个量子计算机在大约七个小时内打破RSA-2048，并使用800,000个不完美的Qubits并在大约300个时间段内执行单一的模块化添加。这种方法可以应用于任何中间RSA大小，并且与使用256位椭圆曲线的比特币等加密货币有关。

In a related development, financial heavyweight BlackRock has revised its IBIT prospectus to include a cautionary note on quantum computing. The IBIT prospectus, as mandated by law, must disclose potential risks tied to investing in bitcoin. It covers aspects such as the asset’s pronounced price volatility and describes scenarios in which a 51% attack might unfold.

在相关的开发中，金融重量级贝莱德（Blackrock）修改了其IBIT招股说明书，其中包括有关量子计算的警示说明。法律规定的IBIT招股说明书必须披露与投资比特币相关的潜在风险。它涵盖了诸如资产明显价格波动之类的方面，并描述了可能展开51％攻击的情况。

These disclosures were already present in previous versions of IBIT’s prospectus, which was last updated in May. The newest addition to IBIT’s prospectus introduces a cautionary note: “In the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users’ personal information and/or resulted in the theft of users’ digital assets.”

这些披露已经存在于IBIT招股说明书的先前版本中，该版本是在5月的最后更新。 IBIT招股说明书的最新成员引入了警告：“过去，数字资产源代码中的缺陷已被暴露和利用，包括为用户提供某些功能，暴露用户的个人信息和/或导致用户盗窃数字资产的缺陷。”

The document then elaborates, warning that advancements in quantum computing could compromise the cryptographic foundation underpinning Bitcoin.

然后该文档详细说明，警告量子计算的进步可能会损害加密基础基础的基础比特币。

“The cryptography underlying Bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry, and quantum computing, could result in such cryptography becoming ineffective,” Blackrock’s IBIT prospectus states.

“加密基础比特币可能被证明是有缺陷或无效的，或数学和/或技术的发展，包括数字计算，代数几何和量子计算的进步，可能会导致这种密码学变得无效，” BlackRock的IBIT招股说明书。

The prospectus adds:

招股说明书补充说：

In any of these circumstances, a malicious actor may be able to compromise the security of the Bitcoin network or take the Trust’s bitcoin, which would adversely affect the value of the Shares.

在这些情况下，恶意演员可能能够损害比特币网络的安全性或采取信任的比特币，这将对股票的价值产生不利影响。

BlackRock’s disclosure continues by suggesting that the Bitcoin network’s functionality could deteriorate to a point where it loses its appeal to users, potentially diminishing overall demand for bitcoin. “Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Shares,” the prospectus notes.

BlackRock的披露继续表明，比特币网络的功能可能会恶化，以使其失去对用户的吸引力，从而有可能减少对比特币的总需求。招股说明书指出：“即使比特币以外的其他数字资产受到类似情况的影响，对源代码或加密资产的信心的任何降低通常都可能对数字资产的需求产生负面影响，从而对股票的价值产生不利影响。”

As quantum computing technology progresses, the crypto community faces the challenge of its potential to destabilize Bitcoin’s security infrastructure. BlackRock’s revised caution highlights the vulnerability of cryptographic protocols in the face of rapid technological shifts. While the threat is still quite speculative, its recognition by major institutional actors marks a critical juncture. The sector needs to balance forward-thinking innovation with the necessity of safeguarding Bitcoin’s durability in a fast-evolving digital epoch.

随着量子计算技术的进步，加密货币社区面临着破坏比特币安全基础架构稳定的挑战。贝莱德（Blackrock）的修订谨慎强调了面对快速技术转变时加密协议的脆弱性。尽管威胁仍然很投机，但主要机构参与者的认可标志着关键时刻。该行业需要在快速发展的数字时代中维护比特币的耐用性，以平衡前瞻性创新。
