Bitcoin's Quantum Quandary: Is SHA-384 Security the Answer?

比特幣的量子難題：SHA-384安全是答案嗎？

Bitcoin, the king of crypto, faces a looming threat: quantum computing. While current security measures seem impenetrable, quantum algorithms could shatter the encryption that protects our digital gold. Let's dive into Bitcoin's quantum vulnerability and explore potential solutions, focusing on SHA-384 security.

Bitcoin是加密貨幣之王，面臨著迫在眉睫的威脅：量子計算。儘管當前的安全措施似乎無法穿透，但量子算法可能會破壞保護我們的數字黃金的加密。讓我們研究比特幣的量子漏洞並探索潛在的解決方案，重點是SHA-384安全性。

The Quantum Threat to Bitcoin

對比特幣的量子威脅

Bitcoin relies on elliptic curve cryptography (specifically, the secp256k1 curve) for generating keys. Brute-forcing this encryption would take longer than the universe has existed...or so we thought. Quantum algorithms, like Shor's algorithm, could break this much faster, jeopardizing private keys. The increasing availability of blockchain addresses makes this a present, not just future, worry.

比特幣依賴橢圓曲線密碼學（特別是SECP256K1曲線）來生成密鑰。野蠻的加密需要比宇宙存在的更長的時間……或者我們想。量子算法（例如Shor's算法）可能會損害這一更快，危害私鑰的速度。區塊鏈地址的可用性越來越大，這使得這不僅是將來的擔憂。

Enter Post-Quantum Cryptography (PQC)

輸入量子後加密（PQC）

The solution? Post-Quantum Cryptography (PQC), a new generation of algorithms designed to withstand quantum attacks. PQC uses hard mathematical problems that are resistant to both classical and quantum attacks, like lattice-based cryptography and hash-based signatures. Organizations like the US National Institute of Standards and Technology (NIST) are already testing PQC algorithms.

解決方案？量詞後加密（PQC），一種新一代的算法，旨在承受量子攻擊。 PQC使用對經典和量子攻擊具有抵抗力的硬性數學問題，例如基於晶格的加密和基於哈希的特徵。美國國家標準技術研究所（NIST）等組織已經在測試PQC算法。

Bitcoin.ℏ and SHA-384: A Quantum-Resistant Alternative?

Bitcoin.ℏ和SHA-384：一種抗量子的替代方案？

Implementing PQC on existing blockchains is challenging. Enter Bitcoin.ℏ, built on Hedera Hashgraph, which takes a different approach by adopting SHA-384 cryptography. SHA-384, a truncated version of SHA-512, offers collision resistance. While Grover's algorithm can reduce brute-force search time on hash functions, SHA-384 encryption, even with reduced strength, still provides a robust 192-bit security level.

在現有區塊鏈上實施PQC是具有挑戰性的。輸入基於Hedera Hashgraph的Bitcoin.ℏ，該方法通過採用SHA-384密碼學採用了不同的方法。 SHA-384是SHA-512的截斷版本，具有碰撞阻力。儘管Grover的算法可以減少哈希功能上的蠻力搜索時間，但SHA-384加密即使強度降低，仍然提供了強大的192位安全水平。

Why SHA-384 Matters

為什麼SHA-384很重要

Bitcoin.ℏ’s adoption of Hedera Hashgraph and SHA-384 signifies a forward-thinking approach to security. It works within the limitations of current tech while providing a strong defense against quantum threats. In contrast, Monero is undergoing upgrades to enhance its resistance to quantum technologies, showing a broader trend in the crypto world. Even Bitcoin is seeing transitional periods, as analysts watch key levels to determine future uptrends, highlighting the need for constant vigilance in a rapidly evolving landscape.

Bitcoin.ℏ採用Hedera Hashgraph和SHA-384表示對安全的前瞻性方法。它在當前技術的局限性範圍內起作用，同時為量子威脅提供了強有力的防禦。相比之下，Monero正在進行升級，以增強其對量子技術的抵抗力，顯示出加密世界的更廣泛趨勢。甚至比特幣都在看到過渡期，因為分析師觀察關鍵水平以確定未來的上升趨勢，從而強調了在快速發展的景觀中不斷警惕的必要性。

The Future is Quantum-Resistant (Hopefully!)

未來是抗量子的（希望！）

The crypto world can't afford to ignore the quantum threat. While widespread quantum computing is still on the horizon, the foundation for quantum-resistant blockchains needs to be laid now. Projects like Bitcoin.ℏ, with its SHA-384 security, are leading the charge. With fault tolerance, low energy consumption, and scalability, it presents a compelling alternative.

加密世界無力忽略量子威脅。儘管廣泛的量子計算仍在範圍內，但現在需要奠定抗量子區塊鏈的基礎。像比特幣這樣的項目。具有容錯，低能消耗和可伸縮性，它提出了令人信服的替代方案。

So, is SHA-384 the ultimate answer? Maybe not, but it's a crucial step in the right direction. The race against the quantum clock is on, and it's a wild ride, but hey, at least we're not bored!

那麼，SHA-384是最終的答案嗎？也許不是，但這是朝著正確方向邁出的關鍵步驟。與量子鐘的比賽已經開始，這是一次瘋狂的旅程，但是，嘿，至少我們並不感到無聊！
