Blockstream 創辦人認為量子運算可能使比特幣區塊鏈受益

儘管人們普遍擔心量子運算的可怕潛力，但 Blockstream 創辦人認為這實際上有利於區塊鏈的安全。

Google recently made a breakthrough in quantum computing technology that has left the crypto community spooked.

谷歌最近在量子計算技術方面取得了突破，令加密社群感到震驚。

The major tech advancement came with a remarkable increase in the computational power of chips, leading some to believe that hackers could now attack the cryptographic keys that secure Bitcoin.

主要的技術進步伴隨著晶片運算能力的顯著提高，導致一些人相信駭客現在可以攻擊保護比特幣安全的加密金鑰。

If dormant wallets, like Satoshi’s, were liquidated, it could cause a mass destabilising event for the coin.

如果像中本聰這樣的休眠錢包被清算，可能會導致代幣出現大規模不穩定事件。

But, according to prominent blockchain developer Adam Back, quantum computing might actually help secure the protocol.

但是，根據著名的區塊鏈開發人員 Adam Back 的說法，量子運算實際上可能有助於保護協議的安全。

Prominent blockchain developer Adam Back has argued that Bitcoin can leverage recent upgrades like Taproot to become quantum computing resistant without needing to make drastic changes to the blockchain.

著名的區塊鏈開發商 Adam Back 認為，比特幣可以利用最近的升級（例如 Taproot）來抵抗量子運算，而無需對區塊鏈進行大幅改變。

Responding to an X (formerly Twitter) thread, Back suggested that a Bitcoin Improvement Proposal to defend against quantum computers like Willow may not be needed.

Back 在回覆 X（以前的 Twitter）貼文時表示，可能不需要比特幣改進提案來防禦像 Willow 這樣的量子電腦。

maybe not needed. you can be quantum ready using a taproot leaf committing to a future soft-forkable PQ signature opcode, and a hash-based key scheme. then you can migrate to that PQ ready Schnorr signature, while only paying current signature sizes. then people will calm down.

也許不需要。您可以使用提交未來可軟分叉 PQ 簽章操作碼的主根葉子和基於雜湊的金鑰方案來做好量子準備。那麼您可以遷移到 PQ 就緒的 Schnorr 簽名，同時只需支付目前的簽名大小。然後人們就會平靜下來。

Okay, that’s a lot of complicated words.

好吧，說了這麼多複雜的話。

As simply as possible, Back is implying that Bitcoin could leverage the Taproot leaf upgrade and create an operation code designed to stand up against quantum computing attacks.

Back盡可能簡單地暗示比特幣可以利用主根葉升級並創建旨在抵禦量子運算攻擊的操作程式碼。

By ensuring it is “soft-forkable”, the code could then be updated intermittently depending on flaws exposed by quantum computing without requiring a complete overhaul of the Bitcoin blockchain.

透過確保它是「可軟分叉」的，程式碼可以根據量子計算暴露的缺陷間歇性地更新，而不需要對比特幣區塊鏈進行徹底檢修。

Then, moving to an updated Schnorr signature (a more efficient and secure way of digitally signing transactions on the blockchain) could help defend the protocol to an ever greater level.

然後，轉向更新的 Schnorr 簽章（一種在區塊鏈上對交易進行數位簽章的更有效率、更安全的方式）可以幫助將協議保護到更高的水平。

The current state of quantum computing is decades away from actually posing a threat to Bitcoin’s blockchain.

量子運算的當前狀態距離真正對比特幣區塊鏈構成威脅還有幾十年的時間。

But, the fact that this threat exists could spur developers into action, leading them to create a quantum-resistant, inherently more secure network.

但是，這種威脅存在的事實可能會促使開發人員採取行動，導致他們創建一個抗量子的、本質上更安全的網路。

And because the industry has several years before a compromise could become a reality, Bitcoin can be well-prepared for a post-quantum world while other networks suffer.

而且由於該行業距離妥協成為現實還有幾年的時間，因此當其他網路遭受損失時，比特幣可以為後量子世界做好充分準備。

Essentially, he’s implying this is an opportunity for Bitcoin to be proactive, rather than reactive.

從本質上講，他暗示這是比特幣主動而非被動的機會。
