區塊鏈、可追溯性和 Zashi 錢包：探索隱私的細微差別

探索 Zashi 錢包、區塊鏈可追溯性的最新發展及其對加密貨幣交易隱私的影響。

The world of blockchain is constantly evolving, and the intersection of privacy, traceability, and user experience is becoming increasingly important. Let's dive into the recent buzz around Zashi wallet and how it interacts with blockchain traceability.

區塊鏈世界在不斷發展，隱私、可追溯性和用戶體驗的交集變得越來越重要。讓我們深入了解一下最近圍繞 Zashi 錢包的熱門話題，以及它如何與區塊鏈可追溯性交互。

Zashi Wallet: A Double-Edged Sword for Privacy?

Zashi錢包：保護隱私的雙刃劍？

Zashi wallet, developed by Electric Coin Co. (the team behind Zcash), aims to provide users with a way to transact ZEC privately. However, recent findings by blockchain investigator ZachXBT have highlighted a potential vulnerability in Zashi's integration with NEAR Intents. This integration, designed for cross-chain transactions, was found to have a flaw that could compromise user anonymity. ZachXBT's experiment revealed that refund transactions were being sent to the same transparent address from which the funds were initially shielded, creating a visible link between shielded and unshielded addresses.

Zashi錢包由Electric Coin Co.（Zcash背後的團隊）開發，旨在為用戶提供一種私下交易ZEC的方式。然而，區塊鏈調查員 ZachXBT 最近的發現凸顯了 Zashi 與 NEAR Intents 集成中的潛在漏洞。這種專為跨鏈交易而設計的集成被發現存在可能損害用戶匿名性的缺陷。 ZachXBT 的實驗表明，退款交易被發送到最初屏蔽資金的同一個透明地址，從而在屏蔽地址和未屏蔽地址之間創建了可見的鏈接。

Traceability Trade-offs

可追溯性權衡

The core issue lies in how NEAR Intents handles refunds for cross-chain transactions. Because the NEAR Intents Zcash address is publicly visible, refund transactions are processed transparently. This means anyone could potentially match the timing and amounts between the NEAR Intents system and the refund itself, deanonymizing the user's t-address.

核心問題在於NEAR Intents如何處理跨鏈交易的退款。由於 NEAR Intents Zcash 地址是公開可見的，因此退款交易的處理是透明的。這意味著任何人都可以匹配 NEAR Intents 系統和退款本身之間的時間和金額，從而使用戶的 T 地址去匿名化。

This incident highlights a critical tension between the desire for privacy and the inherent traceability of blockchain transactions. While Zcash aims to offer shielded transactions, the integration with other systems can sometimes create unforeseen vulnerabilities.

這一事件凸顯了對隱私的渴望與區塊鏈交易固有的可追溯性之間的嚴重緊張關係。雖然 Zcash 的目標是提供屏蔽交易，但與其他系統的集成有時會產生不可預見的漏洞。

Zashi's Response and the Future of Privacy

Zashi 的回應與隱私的未來

The good news is that the Zashi development team has acknowledged the issue and plans to introduce ephemeral addresses, which are temporary wallet addresses that disappear after each transaction to reduce traceability. They also plan to include shielded refunds within NEAR Intents in a future update. These updates are essential for maintaining the privacy that Zcash users expect.

好消息是，Zashi 開發團隊已經承認了這個問題，併計劃引入臨時地址，這些地址是臨時錢包地址，在每次交易後都會消失，以減少可追溯性。他們還計劃在未來的更新中將屏蔽退款納入 NEAR Intents 中。這些更新對於維護 Zcash 用戶期望的隱私至關重要。

NEAR Intents: Powering Cross-Chain Activity

NEAR 意圖：推動跨鏈活動

NEAR Intents is a multichain transaction protocol that automates cross-chain actions. It's been experiencing a surge in activity, with transaction volumes nearly doubling month-on-month and user counts climbing. The appeal of NEAR Intents lies in its ability to simplify cross-chain transactions, allowing users to state their desired outcome (e.g., swapping tokens across chains) without manually bridging assets or confirming multiple steps.

NEAR Intents 是一種多鏈交易協議，可自動執行跨鏈操作。它的活動量激增，交易量環比幾乎翻倍，用戶數量不斷攀升。 NEAR Intents 的吸引力在於它能夠簡化跨鏈交易，允許用戶陳述他們想要的結果（例如，跨鏈交換代幣），而無需手動橋接資產或確認多個步驟。

The Zashi–Intents Loop: A Template for Privacy Wallets?

Zashi-意圖循環：隱私錢包的模板？

The integration of Zashi with NEAR Intents offers a glimpse into the future of privacy wallets. By leveraging intents to handle the heavy lifting of cross-chain transactions, Zashi provides a cleaner user experience for everyday participants, making private ZEC more usable. This model could potentially be replicated by other privacy wallets.

Zashi 與 NEAR Intents 的集成讓我們得以一睹隱私錢包的未來。通過利用意圖來處理繁重的跨鏈交易，Zashi 為日常參與者提供了更清晰的用戶體驗，使私有 ZEC 更可用。這種模式可能會被其他隱私錢包複製。

Immutable's IMU: A Mascot for Blockchain Gaming

Immutable 的 IMU：區塊鏈遊戲的吉祥物

While not directly related to privacy, it's worth noting the efforts of other blockchain projects to enhance user experience. Immutable has unveiled a new mascot, IMU, to create a stronger connection with players and developers in the blockchain gaming space. This move reflects a broader trend of making blockchain technology more approachable and community-driven.

雖然與隱私沒有直接關係，但值得注意的是其他區塊鏈項目在增強用戶體驗方面所做的努力。 Immutable 推出了一個新的吉祥物 IMU，旨在與區塊鏈遊戲領域的玩家和開發者建立更緊密的聯繫。此舉反映了一種更廣泛的趨勢，即使區塊鏈技術變得更加平易近人且由社區驅動。

Final Thoughts

最後的想法

The recent findings regarding Zashi wallet and NEAR Intents serve as a reminder of the ongoing challenges in achieving true privacy on the blockchain. However, the quick response from the Zashi team and the potential for future improvements offer hope for a more private and user-friendly future. The interplay between traceability and privacy will continue to shape the evolution of blockchain technology. So, keep your eyes peeled, folks – the future of blockchain is anything but boring!

最近有關 Zashi 錢包和 NEAR Intents 的調查結果提醒人們，在區塊鏈上實現真正的隱私所面臨的持續挑戰。然而，Zashi 團隊的快速響應和未來改進的潛力為更加私密和用戶友好的未來帶來了希望。可追溯性和隱私之間的相互作用將繼續影響區塊鏈技術的發展。所以，伙計們，請擦亮眼睛——區塊鏈的未來絕不會無聊！
