尽管担心，比特币（BTC）已经可以免受量子计算攻击

比特币（BTC -0.65％）所有者通常将最大的硬币不变品质吹捧为主要卖点。但是，如果比特币的技术平台永远不会改变，它如何应对意外的挑战并适应新的安全威胁？

Some cryptocurrency investors are concerned about data security in the future. Bitcoin (BTC -0.65%) owners often highlight the largest coin’s unchanging qualities as a major selling point. But if Bitcoin’s technical platform never changes, how will it meet unexpected challenges and adapt to new security threats? In particular, won’t Bitcoin’s encryption crumble rapidly when faced with the assault of quantum computing systems?

一些加密货币投资者将来关心数据安全。比特币（BTC -0.65％）的所有者通常会突出最大的硬币不变的品质作为主要的卖点。但是，如果比特币的技术平台永远不会改变，它将如何应对意外的挑战并适应新的安全威胁？特别是，当面对量子计算系统的攻击时，比特币的加密不会迅速崩溃吗？

There’s something you should know before you write off Bitcoin entirely, or dive into it head first. Bitcoin can have the system stability cake and eat incoming threats too.

在您完全注销比特币之前，您应该知道一些问题，或者先浏览它。比特币可以具有系统稳定性蛋糕，也可以吃进来的威胁。

Bitcoin is indeed changing over time, and should be safe from quantum computing attacks in the long run. It’s just very unlikely to make sudden turns into dangerous or economically unsound moves, such as changing its inflation-proof coin-minting process.

比特币的确随着时间的推移而变化，从长远来看，应该可以防止量子计算攻击。突然转变为危险或经济上不健全的举动，例如改变其防通胀的硬币造成过程，这是非常不可能的。

The imagined threat

想象中的威胁

Quantum computers are expected to disrupt many industries eventually. A powerful system of this type is perfect for finding patterns in seemingly random data. They will crack the genetic code of genetic diseases, provide the most accurate weather forecasts ever, and bring clarity to the chaos of financial markets.

预计量子计算机最终会破坏许多行业。这种类型的强大系统非常适合在看似随机的数据中查找模式。他们将破解遗传疾病的遗传守则，提供有史以来最准确的天气预报，并为金融市场的混乱带来清晰度。

And of course, they will be able to crack the encryption algorithms at the heart of Bitcoin and other cryptocurrencies.

当然，他们将能够破解比特币和其他加密货币核心的加密算法。

If and when that happens, that must be the end of Bitcoin as you know it. Scoundrels and miscreants will be able to change, delete, or insert data into Bitcoin’s blockchain ledger, moving billion-dollar fortunes with the click of a quantum-powered mouse.

如果发生这种情况，那一定是比特币的终结。无人群和不法行为将能够更改，删除或将数据插入比特币的区块链分类帐中，单击量子驱动的鼠标，将数据移动了十亿美元的命运。

The “feature” that surely leaves the data security door open

肯定会使数据安全门打开的“功能”

This wouldn’t be such a scary situation if Bitcoin’s technology wasn’t so unchangeable. You often hear crypto bulls touting the firm cap of 21 million Bitcoins as an immovable guard against inflation. Once the last fraction of the 21-millionth digital coin has been minted, there simply won’t be any more production. With 19.83 million Bitcoin already created, that’s 94.4% of all Bitcoin that ever will exist.

如果比特币的技术不那么改变，这将不是令人恐惧的情况。您经常听到加密公牛吹捧2100万比特币的公司盖，以防止通货膨胀。一旦铸造了2100万个数字硬币的最后一部分，根本就不会再有生产了。由于已经创建了1983万比特币，这是所有将存在的比特币的94.4％。

So Bitcoin isn’t changing. When the bad actors finally get their hands on game-changing quantum computers, Bitcoin’s data security must fall.

因此，比特币没有改变。当坏演员最终动手改变游戏规则的量子计算机时，比特币的数据安全必须下降。

The end.

How Bitcoin’s updates actually work

比特币的更新实际上是如何工作的

Hold your horses, dear investor.

亲爱的投资者，握住你的马。

The computing platform behind Bitcoin can indeed change over time. The Bitcoin Core software that manages the blockchain ledger and the Bitcoin mining procedure is up to version 28.1 these days. The latest update fixed a few bugs and added some developer-friendly features. It was released on October 2, 2024, to be followed by a more substantial “major version” in the spring of 2025.

比特币背后的计算平台确实可以随着时间的流逝而改变。如今，管理区块链分类帐和比特币挖掘程序的比特币核心软件如今已达到28.1版。最新更新修复了一些错误，并添加了一些对开发人员友好的功能。它于2024年10月2日发布，随后在2025年春季发布了更为实质性的“主要版本”。

These changes could include very important features and software bits, including the limit of 21 million coins and the encryptions methods in use.

这些更改可能包括非常重要的功能和软件位，包括2100万个硬币的限制和使用的加密方法。

And there are already encryption methods that are hard to crack with quantum computing systems. The National Institute of Standards and Technology (NIST) announced the first federal standards for quantum-hardened encryption in 2022. Development efforts toward this goal started in 2016. IBM (IBM -1.73%) included these quantum-resistant algorithms in the z16 mainframe systems the same year, and will make these encryption solutions mandatory over time. Microsoft (MSFT -1.00%) is quietly rolling out data security with quantum-safe algorithms, too.

而且已经有一些加密方法很难使用量子计算系统破解。美国国家标准技术研究所（NIST）宣布了2022年量子硬化加密的第一个联邦标准。针对这一目标的发展努力始于2016年。IBM（IBM -1.73％）包括这些Quantum对量子的算法的Z16 Mainfame Systems中的这些抗量子算法，并将使这些纳入量化的算法超过时间。 Microsoft（MSFT -1.00％）也通过量子安全算法悄悄地推出数据安全性。

There’s absolutely no reason to believe that the Bitcoin developer community will let the whole system run into quantum-based hacking issues. Long before quantum computers grow powerful enough to pose a real threat, the old-school SHA-256 hash function will be replaced by a quantum-safe alternative.

绝对没有理由相信比特币开发人员社区会让整个系统陷入基于量子的黑客问题。在量子计算机生长足够强大以构成真正的威胁之前，老式的SHA-256哈希功能将被量子安全的替代方法取代。

The key thing to remember is that updates only happen with a proper majority approval. More than half of the systems running the Bitcoin blockchain need to install the new version in order to achieve consensus on approving each transaction on the public ledger. A so-called 51% attack is possible, but only if you control more than half of the world’s Bitcoin mining power — a tall order even for trillion-dollar tech giants or governments. And before that, every software update goes through a meticulous process of planning, development, testing, and installation.

要记住的关键是，只有大多数批准才会发生更新。运行比特币区块链的系统中，有一半以上需要安装新版本，以便在批准公共分类帐中的每笔交易方面达成共识。可能发生的51％攻击是可能的，但前提是您控制了世界上超过一半的比特币采矿能力 - 即使对于万亿美元的技术巨头或政府来说，这是一个艰巨的任务。在此之前，每个软件更新都经历了计划，开发，测试和安装的细致过程。

And it would not be in the community’s best interest to adopt software versions with unwanted features. The 21-million coin cap is safe, because upping that limit would immediately lower the value of the Bitcoin holdings and mining systems that made it possible to change that particular number.

采用具有不必要功能的软件版本并不符合社区的最大利益。 2100万硬币上限是安全的，因为加大该限制将立即降低比特币持有量和采矿系统的价值，从而使该特定数量成为可能。

Bitcoin owners shouldn’t worry about quantum hackers

比特币所有者不必担心量子黑客

So Bitcoin developers have the freedom to tackle technical challenges, including the future threat of hackers with quantum computers. The system is also sophisticated enough to resist unwanted software changes. No project, system, or organization is ever 100% safe against every threat, and that’s only more true in the unfamiliar cryptocurrency market. Bitcoin investors shouldn

因此，比特币开发人员可以自由应对技术挑战，包括用量子计算机造成的黑客威胁。该系统也足够复杂，可以抵抗不需要的软件更改。没有任何项目，系统或组织对每一个威胁都有100％安全，而且在陌生的加密货币市场中，这只是更真实的。比特币投资者应该
