夜幕降临：以太坊区块链的增强隐私协议

在迅速发展的区块链技术世界中，EY的夜幕降临协议已成为一个重大发展。

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.

在迅速发展的区块链技术世界中，EY的夜幕降临协议已成为一个重大发展，尤其是用于增强具有隐私功能的以太坊区块链。该协议为企业提供了一个解决方案，可以通过其公共网络执行机密操作。随着NightFall_4的引入及其零知识汇总技术的集成，该系统带来了大量的性能和保护。此更新标志着EY和更广泛的区块链社区的关键成就，因为它系统地解决了阻碍系统采用的广泛采用的可扩展性和交易安全问题。

What Is Nightfall?

什么是夜幕降临？

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.

夜幕降临平台用作在以太坊区块链基础架构顶部运行的第2层协议。第2层协议可通过在链上执行交易，从而减少以太坊主网上的工作量，从而使交易更快，更便宜。夜幕降临的隐私特征使企业能够根据以太坊的安全标准通过私人交易来维持运营透明度。

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，该协议开始于实施乐观的汇总技术，尽管这需要验证交易的挑战期，并且需要特定的时间范围来进行交易终止，从而为潜在的分歧创造了一个窗口。最新更新删除了以前的乐观卷起，以实现零知识汇总，并提供快速交易终止性而无需等待时间。

Who Is Nightfall For?

谁是夜幕降临？

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.

夜幕降临解决方案针对的是需要数据隐私在区块链技术中的企业。与许多传统区块链一样，以太坊的交易数据库都可以被所有用户查看。这种完整的可见性为处理机密业务信息（例如商业秘密）的组织构成了障碍，以便在区块链上有效运行。

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.

夜幕降临解决方案为机密交易提供了一个环境，使企业能够保持数据隐私，同时享受以太坊区块链的安全功能。该协议为金融服务和供应链管理等领域的公司带来了关键的好处，这些公司处于采用区块链解决方案的最前沿。

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.

最后，NightFall_4是一个可访问的部署平台，因为它提供了直接的使用，使各种规模的公司可以采用它。源代码的公共领域性质还允许较小的公司或初创公司在不需要昂贵的专有解决方案的情况下利用协议。

Milestones and History of Nightfall

里程碑和夜幕降临的历史

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.

将夜幕降临协议放置在公共领域的倡议始于EY于2019年的最初发布。此举是由更广泛的努力驱动的，以引入以太坊交易的隐私协议，以应对公司对交易隐私的需求不断上升。 EY对具有隐私特征的企业区块链解决方案的奉献精神的最早迹象在夜幕降临的发展中变得明确，这是朝着这一目标迈出的重要一步。

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.

自首次发布以来，夜幕降临协议通过多个更新进行了进展，直到夜幕降临_4的发行版，该版本是协议的第四版。每个更新都带来了改进系统的新功能。另一方面，该体系结构的最新版本特别关注交易速度和最终性增强。由于此更新解决了许多传统上阻止组织采用区块链隐私解决方案的隐私问题，因此企业用户可能会更快地采用NightFall_4的采用。
