比特幣 BTC/USD 可能需要經歷昂貴且耗時的更新過程，以抵禦未來量子運算的威脅

Bitcoin (CRYPTO: BTC) might need to undergo a costly and time-consuming update process to ward off the threat from quantum computing in the future, according to a report.

一份報告稱，比特幣（CRYPTO：BTC）可能需要經歷昂貴且耗時的更新過程，以抵禦未來量子運算的威脅。

What Happened: A study, led by the University of Kent's School of Computing, estimated that a protocol update to protect Bitcoin from quantum computing threats would require taking the cryptocurrency offline for about 76 days — provided 100% of the bandwidth is committed to the process, Forbes reported.

發生了什麼：由肯特大學計算機學院領導的一項研究估計，保護比特幣免受量子計算威脅的協議更新需要使加密貨幣離線大約 76 天——前提是該過程需要 100% 的頻寬。 》報道。

However, if 25% of the bandwidth is allowed, which would enable users to continue mining and trading at a slower pace, the update would take nearly 305 days or 10 months.

然而，如果允許25%的頻寬，這將使用戶能夠以較慢的速度繼續挖礦和交易，那麼更新將需要近305天或10個月的時間。

In the scenario of 76 days of downtime, the update could cost around $912 million, the report estimated.

報告估計，在停機 76 天的情況下，更新可能花費約 9.12 億美元。

The more feasible 305-day downtime would lead to increased transaction fees and slower transaction confirmation times, leading to decreased market confidence.

更可行的305天停機時間將導致交易費用增加和交易確認時間變慢，從而導致市場信心下降。

The study found that Bitcoin had no other option but to replace the currently used cryptographic algorithm with the so-called "post-quantum" technology, which is immune to quantum attacks, and not doing so would be “devastating.”

研究發現，比特幣別無選擇，只能用所謂的「後量子」技術取代目前使用的密碼演算法，這種技術不受量子攻擊的影響，不這樣做將是「毀滅性的」。

Why It Matters: The increase in threat perception to Bitcoin’s encryption comes in the wake of Google’s new “Willow” quantum computing chip, which can perform computations in five minutes that would take supercomputers 10 septillion years to complete.

重要性：隨著Google新型「Willow」量子運算晶片的推出，人們對比特幣加密的威脅認知增加，該晶片可以在五分鐘內完成超級電腦需要 10 億年才能完成的運算。

However, some experts believe that the threat to Bitcoin’s security is still a distant one. Himanshu Maradiya, the CEO of CIFDAQ, a blockchain ecosystem company, stated that the chip was “lightyears away” from breaking Bitcoin’s security.

然而，一些專家認為，對比特幣安全的威脅仍然遙遠。區塊鏈生態系統公司 CIFDAQ 的執行長 Himanshu Maradiya 表示，該晶片距離破壞比特幣的安全性「還差很遠」。

Well-known technologist Jameson Lopp had said earlier that the inviolable properties of Bitcoin would eventually be violated.

知名技術專家詹姆森·洛普先前曾表示，比特幣不可侵犯的屬性最終會受到侵犯。
