比特币准备抵御量子计算的生存威胁

量子计算无与伦比的处理能力源于其利用量子物理原理以以前认为不可能的速度执行计算的能力。

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.

量子计算因其彻底改变包括金融在内的各个行业的潜力而成为头条新闻。其无与伦比的处理能力是由量子物理原理实现的，有一天可能会破解密码算法。鉴于加密货币的安全性严重依赖密码学，这种功能引起了比特币爱好者的担忧。

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:

不过，业内人士和专家认为，比特币的架构和适应性可以帮助其抵御量子计算带来的威胁。方法如下：

Bitcoin's Robust Defense Mechanisms

比特币强大的防御机制

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.

比特币的安全性以加密签名为基础，可验证交易并防止未经授权的更改。这些签名是使用私钥生成的，作为所有权的数学证明。

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，比特币的设计允许通过后量子（PQ）密码学集成新的密码技术。随着量子计算的进步，这种能力在未来可能变得至关重要。

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 联合创始人、著名密码学家 Adam Back 表示，比特币可以通过 PQ 密码学来适应量子挑战。 Back 发明了 Hashcash（比特币工作量证明机制的前身），他解释说，更紧凑、更安全的 PQ 签名方案最终将会出现。

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.

比特币可以将这些进步作为可选功能整合起来，确保网络能够抵御未来的量子威胁。 Back 强调网络的灵活性和保守的升级方法是关键优势。

“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 帖子中写道：“比特币可以将这些方案作为另一种选择。”他补充说，更紧凑、更安全的后量子签名方案最终将会出现。

Ethereum's Proactive Measures for a Quantum-Resistant Future

以太坊为抗量子未来而采取的积极措施

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.

以太坊联合创始人 Vitalik Buterin 也认识到为后量子世界做好准备的重要性。他最近提出了一个简单的硬分叉来保护以太坊免受量子威胁，展示了保护区块链生态系统所需的适应性。

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.

虽然量子计算对加密安全带来了不可否认的风险，但它也有望增强比特币等区块链网络。 Adam Back 等专家引领加密创新，Vitalik Buterin 等思想领袖为抗量子的未来做准备，加密货币领域似乎已经做好了应对未来挑战的准备。
