Zooko：Zcash 為何需要持續更新？

0:00開場

0:00大家好，謝謝各位來到這裡。謝謝你們的到來。我叫 Zooko，今天講的是 Zcash。Zcash 是什麼？Zcash 是貨幣，是給無限文明用的貨幣。Zcash 社群想做出人人都能用、沒人能被拒絕、還能支撐所有人夢想、機會與合作的東西。Hello. Thank you all for being here. Thank you for coming. My name is Zooko, and this is about Zcash. What is Zcash? Zcash is money. Money for an infinite civilization. Zcashers want to make something that everyone can use, that no one can ever be denied, and that can empower everyone's dreams and opportunities and cooperation.

0:32Zcash 也是像 Bitcoin 一樣的加密貨幣。和 Bitcoin 一樣，Zcash 一開始就是 Bitcoin 的複製品，可以說是加了加密的 Bitcoin。我們拿 Bitcoin，把加密做進去。但它在變，而且會持續越變越多。我早年參與 Bitcoin，當時 Bitcoin 之所以長這樣，有一個具體理由：我們想保護And Zcash is a cryptocurrency like Bitcoin. And like Bitcoin, Zcash started as— Zcash just started as a clone of Bitcoin. It was just encrypted Bitcoin. We took Bitcoin, and we added encryption into it. But it's changed, and it continues to change more and more over time. So I was involved in the early days of Bitcoin, and we had a specific reason that Bitcoin is the way it is, which is: we wanted to protect

1:04Bitcoin 的核心價值不被腐化。Bitcoin 的主要目的、價值或原則之一，是貨幣供給的稀缺性。大家都知道 Bitcoin 永遠只會有 2100 萬枚。Bitcoin's essential values from being corrupted. And one of the main purposes, or values, or principles of Bitcoin is scarcity of the money supply. Everyone knows that there's only ever going to be 21 million Bitcoin coins.

1:22Zcash 完全一樣。大家都知道 Zcash 永遠只會有 2100 萬枚，而 Bitcoin 用來保護這種關鍵原則的策略，就是永遠不改。And that's the exact same with Zcash. Zcash. Everyone knows that there will only ever be 21 million Zcash coins, and the strategy they use in Bitcoin to protect this kind of critical principle is never to change.

1:44比特與 Zcash 的升級策略

1:44保護 Bitcoin 的方式，是禁止任何對 Bitcoin 的改動。Zcash 的策略幾乎相反，目標卻一樣：要保護一項核心價值，你就必須不斷改變。The way to protect Bitcoin is to ban any changes to Bitcoin. And the strategy we use in Zcash is almost the opposite strategy for the same goal, which is: in order to protect an essential value, you have to constantly change.

2:02你必須適應使用者需求變化，也適應新威脅與新挑戰。Zcash 上線這 10 年，我們集體升級了很多次。You have to adapt to meet your users' changing needs and to meet new threats and challenges. So in the 10 years that Zcash has been in operation, we have collectively upgraded it many, many times.

2:18每一個點都是又一次，所有 Zcash 使用者集體接受規則改動、讓某方面變好。在開放、分散、誰都能進入的系統裡，你要怎麼允許改動？Each one of these dots is another time that all of the Zcash users collectively accepted a change to the rules that improved something, and how can you allow changes into an open, distributed system that anyone can access?

2:36你要怎麼允許能改善、或能對抗新威脅的改動，同時又不因此開門讓某種改動削弱它、給某人優勢或違反基本原則？How can you allow changes that improve it, or that protect it against a new threat, without thereby opening the door to a change that undermines it, that gives someone an advantage over others or violates its basic principles?

2:53答案是人。大家會保持警覺，只接受能改善 Zcash、符合價值的改動，不接受違反 Zcash 原則的改動。我們用 rough consensus：節點營運者、持幣者、礦工（我們有工作量證明挖礦）和開發團隊，共同認定某次改動有效且值得；只有共識夠，才能改。And the answer is the people. The people are vigilant to accept only changes that improve Zcash and meet their values, and they will not accept changes that violate Zcash's principles. We do this by a rough-consensus policy in which a combination of node operators and coin holders and miners—we have proof-of-work mining—and development teams all collectively agree that a change is valid and worth it, and only if we have sufficient consensus can we make changes.

3:34Ironwood 與量子威脅

3:34最近一次這樣的升級叫 Ironwood，是很好的例子，呼應今天所有頭條：量子電腦、AI、未知新威脅，世界越變越快。Now, the most recent time this happened was called Ironwood, and it's a great example of what's going on today, because you see all the headlines about quantum computers, AIs, unknown new threats—like, the world is changing faster and faster.

3:54我們發現有一項風險威脅每一位 Zcash 使用者，他們的幣可能全部被偷或被毀，就像你現在在媒體上讀到的 Bitcoin 和 Ethereum 一樣。Well, we found one of those risks threatening every Zcash user. They were in danger of all of their coins being stolen or destroyed, same as what you're reading about in the press right now with Bitcoin and Ethereum.

4:13所有 Zcash 開發團隊聚在一起，放下其他事，合作升級 Zcash 修弱點、保護每位使用者，我們成功了。Ironwood 就是今年（2026）夏天發生的事。我們比 AI 早一步，先找到問題、先修好，而很多其他公司、And all of the Zcash development teams got together, set aside everything else, and cooperated to upgrade Zcash to fix the weaknesses and protect every user, which we did successfully. And Ironwood, that was what happened this summer, 2026. We were the ones who got ahead of the AIs, and we found the problem and fixed it before any AIs found it, whereas a lot of other companies and

4:47專案、加密貨幣和軟體包已遭受同樣攻擊。下一關是量子電腦和 AI，Zcash 會再次迎戰，但 Zcash 的強度來自治理流程：它會為挑戰改規則，也會守護原則。projects and cryptocurrencies and software packages have suffered from the same attacks. Now, the next situation we face is quantum computers and AIs, and once again, Zcash is going to rise to meet the challenge, but the strength of Zcash comes from the— the governance process that will make changes to meet challenges, but will also safeguard its principles.

5:21Zcash 的強度來自社群

5:21所以 Zcash 的強度真正來自人。Zcash 就是人。謝謝各位聆聽。So that means the strength of Zcash really comes from the people. Zcash is people. Thank you for listening.
