儘管擔心，比特幣（BTC）已經可以免受量子計算攻擊

比特幣（BTC -0.65％）所有者通常將最大的硬幣不變品質吹捧為主要賣點。但是，如果比特幣的技術平台永遠不會改變，它如何應對意外的挑戰並適應新的安全威脅？

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?

一些加密貨幣投資者將來關心數據安全。比特幣（BTC -0.65％）的所有者通常會突出最大的硬幣不變的品質作為主要的賣點。但是，如果比特幣的技術平台永遠不會改變，它將如何應對意外的挑戰並適應新的安全威脅？特別是，當面對量子計算系統的攻擊時，比特幣的加密不會迅速崩潰嗎？

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.

在您完全註銷比特幣之前，您應該知道一些問題，或者先瀏覽它。比特幣可以具有系統穩定性蛋糕，也可以吃進來的威脅。

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.

比特幣的確隨著時間的推移而變化，從長遠來看，應該可以防止量子計算攻擊。突然轉變為危險或經濟上不健全的舉動，例如改變其防通脹的硬幣造成過程，這是非常不可能的。

The imagined threat

想像中的威脅

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.

預計量子計算機最終會破壞許多行業。這種類型的強大系統非常適合在看似隨機的數據中查找模式。他們將破解遺傳疾病的遺傳守則，提供有史以來最準確的天氣預報，並為金融市場的混亂帶來清晰度。

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

當然，他們將能夠破解比特幣和其他加密貨幣核心的加密算法。

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.

如果發生這種情況，那一定是比特幣的終結。無人群和不法行為將能夠更改，刪除或將數據插入比特幣的區塊鏈分類帳中，單擊量子驅動的鼠標，將數據移動了十億美元的命運。

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

肯定會使數據安全門打開的“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.

如果比特幣的技術不那麼改變，這將不是令人恐懼的情況。您經常聽到加密公牛吹捧2100萬比特幣的公司蓋，以防止通貨膨脹。一旦鑄造了2100萬個數字硬幣的最後一部分，根本就不會再有生產了。由於已經創建了1983萬比特幣，這是所有將存在的比特幣的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，比特幣沒有改變。當壞演員最終動手改變遊戲規則的量子計算機時，比特幣的數據安全必須下降。

The end.

結尾。

How Bitcoin’s updates actually work

比特幣的更新實際上是如何工作的

Hold your horses, dear investor.

親愛的投資者，握住你的馬。

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.

比特幣背後的計算平台確實可以隨著時間的流逝而改變。如今，管理區塊鏈分類帳和比特幣挖掘程序的比特幣核心軟件如今已達到28.1版。最新更新修復了一些錯誤，並添加了一些對開發人員友好的功能。它於2024年10月2日發布，隨後在2025年春季發布了更為實質性的“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.

這些更改可能包括非常重要的功能和軟件位，包括2100萬個硬幣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.

而且已經有一些加密方法很難使用量子計算系統破解。美國國家標準技術研究所（NIST）宣布了2022年量子硬化加密的第一個聯邦標準。針對這一目標的發展努力始於2016年。IBM（IBM -1.73％）包括這些Quantum對量子的算法的Z16 Mainfame Systems中的這些抗量子算法，並將使這些納入量化的算法超過時間。 Microsoft（MSFT -1.00％）也通過量子安全算法悄悄地推出數據安全性。

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.

絕對沒有理由相信比特幣開發人員社區會讓整個系統陷入基於量子的黑客問題。在量子計算機生長足夠強大以構成真正的威脅之前，老式的SHA-256哈希功能將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.

要記住的關鍵是，只有大多數批准才會發生更新。運行比特幣區塊鏈的系統中，有一半以上需要安裝新版本，以便在批准公共分類帳中的每筆交易方面達成共識。可能發生的51％攻擊是可能的，但前提是您控制了世界上超過一半的比特幣採礦能力 - 即使對於萬億美元的技術巨頭或政府來說，這是一個艱鉅的任務。在此之前，每個軟件更新都經歷了計劃，開發，測試和安裝的細緻過程。

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.

採用具有不必要功能的軟件版本並不符合社區的最大利益。 2100萬硬幣上限是安全的，因為加大該限制將立即降低比特幣持有量和採礦系統的價值，從而使該特定數量成為可能。

Bitcoin owners shouldn’t worry about quantum hackers

比特幣所有者不必擔心量子黑客

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，比特幣開發人員可以自由應對技術挑戰，包括用量子計算機造成的黑客威脅。該系統也足夠複雜，可以抵抗不需要的軟件更改。沒有任何項目，系統或組織對每一個威脅都有100％安全，而且在陌生的加密貨幣市場中，這只是更真實的。比特幣投資者應該
