比特币的加密韧性正面临着更新的问题

在Google研究人员建议量子计算机可能能够破坏其加密后，比特币的加密韧性正面临着更新的问题

Bitcoin’s cryptographic resilience is facing renewed questions after a Google researcher suggested that quantum computers may be capable of breaking its encryption far sooner than expected.

在Google研究人员建议量子计算机可能能够比预期的要早得多，比特币的加密韧性正面临着更新的问题。

Craig Gidney, a leading quantum computing researcher at Google, has published new findings suggesting that the hardware requirements to break 2048-bit RSA encryption, a key mathematical element similar to that of Bitcoin, have dropped significantly.

Google领先的量子计算研究人员Craig Gidney发表了新的发现，表明打破2048位RSA加密的硬件要求，这是一种与比特币相似的关键数学元素，已经大大降低。

Earlier estimates placed the threshold at 20 million noisy qubits, but the new projection requires fewer than one million.

较早的估计使该门槛处于2000万个嘈杂的Qubits，但新的预测需要不到一百万。

The reduced computational burden marks a significant leap in quantum capability, although it might take several days instead of a few hours.

减少的计算负担标志着量子能力的显着飞跃，尽管可能需要几天而不是几个小时。

The Google researcher attributes the advancement to more refined quantum algorithms and enhanced error correction techniques that reduce the number of physical qubits needed by encoding logical qubits more efficiently.

Google研究人员将进步归因于更精致的量子算法和增强的误差校正技术，从而减少了通过更有效地编码逻辑量子的物理量子数的数量。

The revelations come as concerns grow over the pace of quantum computing development. Last year, Google unveiled its Willow chip, a next-generation quantum processor that many believe brought real-world threats to digital security closer than previously assumed.

随着量子计算开发的速度不断增长的担忧，启示成朗。去年，Google推出了其Willow Chip，这是一个下一代量子处理器，许多人认为，对数字安全的现实威胁比以前的假设更加接近。

In response, major financial institutions are updating their disclosures. For instance, BlackRock recently flagged quantum computing as a material risk for its Bitcoin ETF product, IBIT.

作为回应，主要的金融机构正在更新其披露。例如，贝莱德最近将量子计算作为其比特币ETF产品IBIT的物质风险。

According to the firm:

根据公司的说法：

“If quantum computing technology is able to advance and significantly increase its capacity relative to the capacity of today’s leading quantum computers, it could potentially undermine the viability of many of the cryptographic algorithms used across the world’s information technology infrastructure, including the cryptographic algorithms used for digital assets like Bitcoin.”

“如果量子计算技术能够相对于当今领先的量子计算机的能力提高并显着提高其能力，那么它可能会破坏世界信息技术基础架构中使用的许多加密算法的生存能力，包括用于比特币等数字资产的加密算法。”

This shift reflects growing awareness that technological breakthroughs could challenge Bitcoin’s foundational encryption earlier than anticipated.

这种转变反映了人们对技术突破可能比预期的要早挑战比特币的基础加密的认识。

Despite the concern, some experts believe the crypto sector still has time to adapt to the potential risks.

尽管担心，一些专家认为加密货币部门仍然有时间适应潜在的风险。

Today’s logical-qubit demos top out at dozens (e.g., Quantinuum’s 12 logical qubits). Gidney’s 1,000,000-qubit figure is about physical (noisy) qubits, not logical. We’re three orders of magnitude away in sheer qubit count, and need major error-rate breakthroughs.

当今的逻辑量表演示是数十个（例如Quantinuum的12个逻辑量子）。 Gidney的1,000,000 Quitighigh数字是关于物理（嘈杂）的Qubits，而不是合乎逻辑的。我们在纯粹的量子数中距离三个数量级，需要重大的错误率突破。

Even the physical-qubit goal is likely 8–12 years out, and a true million-logical-qubit machine is decades away.

即使是物理问题的目标也可能是8 - 12年，而且几十年来真正的百万个逻辑机器机器也是如此。

Meanwhile, Bitcoin analyst Fred Krueger anticipates the emergence of a “quantum-resistant” version of the top crypto.

同时，比特币分析师弗雷德·克鲁格（Fred Krueger）预计，顶级加密版的“量子抗性”版本的出现。

He envisions a network split between a newly fortified Bitcoin and a legacy version, similar to how Ethereum split into ETH and Ethereum Classic.

他设想了一个新的强化比特币与旧版版本之间的网络，类似于以太坊分为ETH和以太坊经典的网络。

According to Krueger:

根据克鲁格：

“Ulimately there will be a fork. ‘Quantum Resistant Bitcoin (QRB)’ and ‘Bitcoin Classic.’ The big money will recognize and push QRB. Some will fight it. Bitcoin Classic (BTC) will become the new Ethereum Classic.”

“乌尔将有一个叉子。'量子比特币（QRB）和'比特币经典'。大笔资金将承认并推动一些比特币经典赛。

Still, if Bitcoin becomes vulnerable in eight years, the network will not have long to adopt a quantum-resistant upgrade. Mentioned in this article

尽管如此，如果比特币在八年内变得容易受到伤害，那么该网络将不会长时间采用抗量子的升级。在本文中提到
