比特幣準備抵禦量子運算的生存威脅

量子計算無與倫比的處理能力源自於其利用量子物理原理以以前認為不可能的速度執行計算的能力。

Quantum computing has been making headlines for its potential to revolutionize various industries, including finance. Its unparalleled processing power, enabled by the principles of quantum physics, could one day break cryptographic algorithms. This capability has raised concerns among Bitcoin enthusiasts, given the cryptocurrency's heavy reliance on cryptography for its security.

量子運算因​​其徹底改變包括金融在內的各個行業的潛力而成為頭條新聞。其無與倫比的處理能力，由量子物理原理實現，有一天可能會破解密碼演算法。鑑於加密貨幣的安全性嚴重依賴密碼學，這種功能引起了比特幣愛好者的擔憂。

However, industry insiders and experts believe that Bitcoin's architecture and adaptability could help it withstand the threat posed by quantum computing. Here's how:

不過，業內人士和專家認為，比特幣的架構和適應性可以幫助其抵禦量子運算帶來的威脅。方法如下：

Bitcoin's Robust Defense Mechanisms

比特幣強大的防禦機制

Bitcoin's security is underpinned by cryptographic signatures that validate transactions and prevent unauthorized alterations. These signatures are generated using private keys, serving as mathematical proof of ownership.

比特幣的安全性以加密簽名為基礎，可驗證交易並防止未經授權的更改。這些簽名是使用私鑰產生的，作為所有權的數學證明。

Moreover, Bitcoin's design allows for the integration of new cryptographic techniques through post-quantum (PQ) cryptography. This capability could become crucial in the future as quantum computing advances.

此外，比特幣的設計允許透過後量子（PQ）密碼學整合新的密碼技術。隨著量子運算的進步，這種能力在未來可能變得至關重要。

According to Adam Back, co-founder of Blockstream and a renowned cryptographer, Bitcoin can adapt to quantum challenges through PQ cryptography. Back, who invented Hashcash—a precursor to Bitcoin's proof-of-work mechanism—explained that more compact and secure PQ signature schemes will eventually emerge.

Blockstream 聯合創始人、著名密碼學家 Adam Back 表示，比特幣可以透過 PQ 密碼學來適應量子挑戰。 Back 發明了 Hashcash（比特幣工作量證明機制的前身），他解釋說，更緊湊、更安全的 PQ 簽名方案最終將會出現。

Bitcoin could integrate these advancements as optional features, ensuring the network's resilience against future quantum threats. Back highlighted the network's flexibility and conservative approach to upgrades as key strengths.

比特幣可以將這些進步作為可選功能整合起來，確保網路能夠抵禦未來的量子威脅。 Back 強調網路的靈活性和保守的升級方法是關鍵優勢。

“Bitcoin can add those schemes as another option,” Back wrote in a Dec. 21 post on X, adding that more compact and secure post-quantum signature schemes will eventually emerge.

Back 在 12 月 21 日的 X 貼文中寫道：「比特幣可以將這些方案作為另一種選擇。」他補充說，更緊湊、更安全的後量子簽名方案最終將會出現。

Ethereum's Proactive Measures for a Quantum-Resistant Future

以太坊為抗量子未來所採取的積極措施

Ethereum co-founder Vitalik Buterin has also recognized the importance of preparing for a post-quantum world. He recently proposed a simple hard fork to protect Ethereum from quantum threats, demonstrating the adaptability required to secure blockchain ecosystems.

以太坊聯合創始人 Vitalik Buterin 也意識到為後量子世界做好準備的重要性。他最近提出了一個簡單的硬分叉來保護以太坊免受量子威脅，展示了保護區塊鏈生態系統所需的適應性。

While quantum computing poses undeniable risks to cryptographic security, it also holds the promise of strengthening blockchain networks like Bitcoin. With experts like Adam Back leading the charge in cryptographic innovation and thought leaders like Vitalik Buterin preparing for a quantum-resistant future, the cryptocurrency space appears well-positioned to tackle the challenges ahead.

雖然量子運算對加密安全帶來了不可否認的風險，但它也有望增強比特幣等區塊鏈網路。 Adam Back 等專家引領加密創新，Vitalik Buterin 等思想領袖為抗量子的未來做準備，加密貨幣領域似乎已經做好了應對未來挑戰的準備。
