夜幕降臨：以太坊區塊鏈的增強隱私協議

在迅速發展的區塊鏈技術世界中，EY的夜幕降臨協議已成為一個重大發展。

In the rapidly evolving world of blockchain technology, EY's Nightfall protocol has emerged as a significant development, particularly for enhancing the Ethereum blockchain with privacy features. The protocol provides enterprises with a solution to perform confidential operations across its public network. With the introduction of Nightfall_4 and its integration of zero-knowledge roll-up technology, the system brought substantial performance and protection enhancements. This update marks a key achievement both for EY and the broader blockchain community as it systematically solves the scalability and transaction security issues that had hindered broader adoption of the system.

在迅速發展的區塊鏈技術世界中，EY的夜幕降臨協議已成為一個重大發展，尤其是用於增強具有隱私功能的以太坊區塊鏈。該協議為企業提供了一個解決方案，可以通過其公共網絡執行機密操作。隨著NightFall_4的引入及其零知識匯總技術的集成，該系統帶來了大量的性能和保護。此更新標誌著EY和更廣泛的區塊鏈社區的關鍵成就，因為它系統地解決了阻礙系統採用的廣泛採用的可擴展性和交易安全問題。

What Is Nightfall?

什麼是夜幕降臨？

The Nightfall platform functions as a layer-2 protocol that operates on top of the Ethereum blockchain infrastructure. Layer-2 protocols serve to reduce the workload on the Ethereum mainnet by performing transactions off-chain, enabling faster and less expensive transactions. The privacy features of Nightfall enable businesses to maintain operational transparency in accordance with Ethereum's security standards through private transactions.

夜幕降臨平台用作在以太坊區塊鏈基礎架構頂部運行的第2層協議。第2層協議可通過在鏈上執行交易，從而減少以太坊主網上的工作量，從而使交易更快，更便宜。夜幕降臨的隱私特徵使企業能夠根據以太坊的安全標准通過私人交易來維持運營透明度。

Initially, the protocol began by implementing optimistic roll-up technology, although this required a challenge period to validate transactions, and a specific time frame was needed for transaction finality, creating a window for potential disagreements. The latest update removes the previous optimistic roll-up to enable zero-knowledge roll-up and provides fast transaction finality without requiring any wait times.

最初，該協議開始於實施樂觀的匯總技術，儘管這需要驗證交易的挑戰期，並且需要特定的時間範圍來進行交易終止，從而為潛在的分歧創造了一個窗口。最新更新刪除了以前的樂觀捲起，以實現零知識匯總，並提供快速交易終止性而無需等待時間。

Who Is Nightfall For?

誰是夜幕降臨？

The Nightfall solution is targeted at businesses that require data privacy in their operational use of blockchain technology. Ethereum, like many traditional blockchains, has its transaction databases viewable by all users. This complete visibility poses an obstacle for organizations handling confidential business information, such as trade secrets, to operate efficiently on the blockchain.

夜幕降臨解決方案針對的是需要數據隱私在區塊鏈技術中的企業。與許多傳統區塊鏈一樣，以太坊的交易數據庫都可以被所有用戶查看。這種完整的可見性為處理機密業務信息（例如商業秘密）的組織構成了障礙，以便在區塊鏈上有效運行。

The Nightfall solution provides an environment for confidential transactions, enabling businesses to maintain data privacy while enjoying the security capabilities of the Ethereum blockchain. This protocol delivers critical benefits to companies in domains like financial services and supply chain management, which are at the forefront of adopting blockchain solutions.

夜幕降臨解決方案為機密交易提供了一個環境，使企業能夠保持數據隱私，同時享受以太坊區塊鏈的安全功能。該協議為金融服務和供應鏈管理等領域的公司帶來了關鍵的好處，這些公司處於採用區塊鏈解決方案的最前沿。

Finally, Nightfall_4 exists as an accessible platform for deployment because it offers straightforward use that enables companies of varying sizes to adopt it. The public domain nature of the source code also allows smaller companies or startups to leverage the protocol without the need for costly proprietary solutions.

最後，NightFall_4是一個可訪問的部署平台，因為它提供了直接的使用，使各種規模的公司可以採用它。源代碼的公共領域性質還允許較小的公司或初創公司在不需要昂貴的專有解決方案的情況下利用協議。

Milestones and History of Nightfall

里程碑和夜幕降臨的歷史

The initiative to place the Nightfall protocol in the public domain began with its initial release by EY in 2019. This move was driven by a broader effort to introduce privacy protocols for Ethereum transactions in response to the rising corporate demand for transaction privacy. The earliest indication of EY's dedication toward enterprise blockchain solutions with privacy features became clear through Nightfall's development as the first significant step towards this goal.

將夜幕降臨協議放置在公共領域的倡議始於EY於2019年的最初發布。此舉是由更廣泛的努力驅動的，以引入以太坊交易的隱私協議，以應對公司對交易隱私的需求不斷上升。 EY對具有隱私特徵的企業區塊鏈解決方案的奉獻精神的最早跡像在夜幕降臨的發展中變得明確，這是朝著這一目標邁出的重要一步。

Since its initial release, the Nightfall protocol progressed through multiple updates until the release of Nightfall_4, which is version four of the protocol. Each update brought new features that improved the system. On the other hand, the most recent version of the architecture saw a particular focus on transaction speed and finality enhancement. Enterprise users will likely embrace the adoption of Nightfall_4 more rapidly as this update solves many of the privacy issues that have traditionally deterred organizations from adopting blockchain privacy solutions.

自首次發布以來，夜幕降臨協議通過多個更新進行了進展，直到夜幕降臨_4的發行版，該版本是協議的第四版。每個更新都帶來了改進系統的新功能。另一方面，該體系結構的最新版本特別關注交易速度和最終性增強。由於此更新解決了許多傳統上阻止組織採用區塊鏈隱私解決方案的隱私問題，因此企業用戶可能會更快地採用NightFall_4的採用。
