比特币 BTC/USD 可能需要经历昂贵且耗时的更新过程，以抵御未来量子计算的威胁

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.

一份报告称，比特币（CRYPTO：BTC）可能需要经历昂贵且耗时的更新过程，以抵御未来量子计算的威胁。

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.

发生了什么：由肯特大学计算机学院领导的一项研究估计，保护比特币免受量子计算威胁的协议更新需要使加密货币离线大约 76 天——前提是该过程需要 100% 的带宽。 ，《福布斯》报道。

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，如果允许25%的带宽，这将使用户能够以较慢的速度继续挖矿和交易，那么更新将需要近305天或10个月的时间。

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

报告估计，在停机 76 天的情况下，更新可能花费约 9.12 亿美元。

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天停机会导致交易费用增加和交易确认时间变慢，从而导致市场信心下降。

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.”

研究发现，比特币别无选择，只能用所谓的“后量子”技术取代目前使用的密码算法，这种技术不受量子攻击的影响，不这样做将是“毁灭性的”。

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：随着谷歌新型“Willow”量子计算芯片的推出，人们对比特币加密的威胁认知有所增加，该芯片可以在五分钟内完成超级计算机需要 10 亿年才能完成的计算。

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，一些专家认为，对比特币安全的威胁仍然遥远。区块链生态系统公司 CIFDAQ 的首席执行官 Himanshu Maradiya 表示，该芯片距离破坏比特币的安全性“还差很远”。

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

知名技术专家詹姆森·洛普此前曾表示，比特币不可侵犯的属性最终会受到侵犯。
