比特币不受量子计算机的影响吗？专家们敲响了警钟，敦促采取行动，以免为时已晚。让我们来分析一下风险以及可以采取的措施。

Bitcoin vs. Quantum Computing: Mitigating the Looming Threat

比特币与量子计算：减轻迫在眉睫的威胁

Bitcoin, Quantum Computing, Threat Mitigation – these aren't just buzzwords; they represent a potentially seismic shift in the crypto landscape. So, what's the deal? Let's break it down.

比特币、量子计算、威胁缓解——这些不仅仅是流行语；它们代表了加密领域潜在的巨大变化。那么，到底是怎么回事呢？让我们来分解一下。

The Quantum Menace: A Ticking Clock for Bitcoin?

量子威胁：比特币的时钟在滴答作响？

The big worry? Quantum computers. These machines, still largely theoretical, have the potential to crack Bitcoin's core cryptography. As Charles Edwards from Capriole Investments pointed out, a significant chunk of Bitcoin – we're talking potentially 25% – could be vulnerable to a quantum attack if those coins aren't moved to quantum-resistant addresses.

最担心的是什么？量子计算机。这些机器在很大程度上仍处于理论阶段，有可能破解比特币的核心密码学。正如 Capriole Investments 的 Charles Edwards 指出的那样，如果不将比特币转移到抗量子地址，那么很大一部分比特币（我们指的是可能为 25%）可能容易受到量子攻击。

Think of it this way: Bitcoin's security relies on the difficulty of reversing the link between a public key (your Bitcoin address) and a private key (which proves you own the Bitcoin). Regular computers can't really do it but quantum computers, using Shor's algorithm, could theoretically make it a walk in the park.

可以这样想：比特币的安全性依赖于逆转公钥（您的比特币地址）和私钥（证明您拥有比特币）之间的链接的难度。普通计算机确实无法做到这一点，但使用肖尔算法的量子计算机理论上可以让它变得轻而易举。

Address Reuse: A Risky Business

地址重用：一项有风险的业务

Here's where things get a bit technical, but stick with me. Early Bitcoin transactions used a system called “pay to public key” (P2PK), which exposed the public key directly. Later, a new system, “pay to public key hash” (P2PKH), hid the public key until a transaction occurred. However, if you reuse a P2PKH address after a transaction, you're exposing that public key again, creating an opening for a quantum attack.

这是事情变得有点技术性的地方，但请跟着我。早期的比特币交易使用一种称为“公钥支付”（P2PK）的系统，该系统直接暴露公钥。后来，一个新系统“支付公钥哈希”（P2PKH）隐藏了公钥，直到交易发生。但是，如果您在交易后重复使用 P2PKH 地址，则会再次暴露该公钥，从而为量子攻击创造机会。

Deloitte's research estimates that a substantial portion of Bitcoin – about 4 million BTC – is stored in these vulnerable addresses. That's like leaving the keys to your Bentley in the ignition.

德勤的研究估计，很大一部分比特币（约 400 万比特币）存储在这些易受攻击的地址中。这就像把宾利车钥匙留在点火开关里一样。

The Race Against Time: Post-Quantum Solutions

与时间赛跑：后量子解决方案

The good news? This isn't a surprise attack. Developers are already working on post-quantum signature schemes – new cryptographic algorithms that are resistant to quantum cracking. The Bitcoin community needs to prioritize these solutions and figure out realistic migration paths.

好消息？这不是突然袭击。开发人员已经在研究后量子签名方案——抵抗量子破解的新密码算法。比特币社区需要优先考虑这些解决方案并找出现实的迁移路径。

Nic Carter, cofounder of Coin Metrics, stresses the urgency of planning for this. He urges the community to prioritize post-quantum signature schemes and realistic migration paths, framing them as engineering work rather than a distant thought experiment. Basic hygiene, like avoiding address reuse, is also crucial.

Coin Metrics 联合创始人 Nic Carter 强调了为此进行规划的紧迫性。他敦促社区优先考虑后量子签名方案和现实的迁移路径，将其视为工程工作而不是遥远的思想实验。基本卫生（例如避免地址重复使用）也至关重要。

Progress in Quantum Computing: Closer Than We Think?

量子计算的进展：比我们想象的更接近？

Quantum computing is no longer just science fiction. Recent breakthroughs show real progress in hardware precision and control. For example, Quantinuum's H-series system achieved a two-qubit gate fidelity of 99.9%. Researchers at RIKEN and Fujitsu developed a 256-qubit processor and plan to expand to 1,000 qubits by 2026.

量子计算不再只是科幻小说。最近的突破表明硬件精度和控制方面取得了真正的进步。例如，Quantinuum 的 H 系列系统实现了 99.9% 的双量子位门保真度。 RIKEN 和富士通的研究人员开发了一款 256 量子位处理器，并计划到 2026 年扩展到 1,000 量子位。

While a quantum computer capable of breaking Bitcoin's encryption is still some time away, the gap is closing. Steve Tippeconnic, a researcher using IBM’s 133-qubit platform, even used quantum interference to solve a small elliptic curve problem, marking a significant milestone.

虽然能够破解比特币加密的量子计算机还需要一段时间，但差距正在缩小。使用 IBM 133 量子位平台的研究人员 Steve Tippeconnic 甚至使用量子干涉解决了一个小的椭圆曲线问题，标志着一个重要的里程碑。

What’s Next? Preparing for the Inevitable

接下来是什么？为不可避免的事情做好准备

So, what can be done? Experts suggest migrating Bitcoin to a quantum-safe signature scheme, but that could require significant coordinated downtime across the network. The consensus? Start planning now.

那么，可以做什么呢？专家建议将比特币迁移到量子安全签名方案，但这可能需要整个网络的大量协调停机时间。共识？现在就开始计划吧。

Conner Brown, the new Head of Strategy at the Bitcoin Policy Institute, comes from a background of digital asset legislation. The Bitcoin Policy Institute (BPI) is a non-profit, non-partisan think tank working to guide America through the rise of Bitcoin and transformative technologies with research and education. It seems like the BPI is ready to contribute to quantum mitigation.

比特币政策研究所新任战略主管康纳·布朗 (Conner Brown) 拥有数字资产立法背景。比特币政策研究所（BPI）是一个非营利、无党派的智库，致力于通过研究和教育引导美国应对比特币和变革性技术的崛起。 BPI 似乎已准备好为量子缓解做出贡献。

Final Thoughts: Don't Panic, But Pay Attention

最后的想法：不要惊慌，但要注意

Bottom line? Quantum computing poses a real, long-term threat to Bitcoin. But it's not time to sell all your holdings and run for the hills. Instead, it's time for the Bitcoin community to get serious about developing and implementing post-quantum solutions. It’s time to get ahead of the curve. Who knows, maybe quantum-resistant Bitcoin will be the next big thing!

底线？量子计算对比特币构成了真正的长期威胁。但现在还不是卖掉所有财产并逃之夭夭的时候。相反，现在是比特币社区认真开发和实施后量子解决方案的时候了。是时候走在前面了。谁知道呢，也许抗量子比特币将成为下一个大事件！
