EY将其以企业为重点的以太坊2层区块链夜幕降临到零知识汇总设计

四大会计公司EY（以前是Ernst＆Young）已将其专注于企业的以太坊层区块链夜幕降低为零知识汇总设计

Big Four accounting firm EY, formerly Ernst & Young, has disclosed a change in the design of its enterprise-focused Ethereum layer-2 blockchain Nightfall to a zero-knowledge rollup.

四大会计公司EY（以前是Ernst＆Young）透露了其以企业为中心的以太坊2层区块链夜幕降至零知识汇总的设计变化。

The firm, which has been running Nightfall with an optimistic rollup design since 2019, says it is now switching to a ZK-rollup model as it becomes more accessible to users and Nightfall’s architecture is being streamlined with its fourth major update, “Nightfall_4.”

自2019年以来，该公司一直以乐观的滚动设计进行夜幕降临，他说，它正在转向ZK滚动模型，因为它变得更容易被用户访问，而夜幕降临的架构正通过其第四个主要更新“ nightfall_4”来简化。

Announced on April 4, Nightfall_4 will also see nearly instant transaction finality on Ethereum and it is becoming more accessible to users with the addition of a new programming language, Aplomb, and a new documentation suite.

NightFall_4于4月4日宣布，还将在以太坊上看到几乎即时的交易终结性，并通过添加新的编程语言，Anplomb和新文档套件来越来越访问用户。

“This change in architecture means nearly instant finality, but it also makes operations simpler since we don’t need a challenger node to secure the network, which is used to detect and correct any errors in transactions,” an EY spokesperson told Cointelegraph.

EY发言人告诉Cointelegraph：“体系结构的这种变化几乎意味着最终的终止性，但它也使操作变得更加简单，因为我们不需要挑战者节点来保护网络，该网络用于检测和纠正交易中的任何错误。”

However, with optimistic rollups, there is a period where transactions are challenged and if they are deemed incorrect, a challenger node will process a competing block.

但是，有了乐观的汇总，在一段时间内，交易受到挑战，如果认为不正确，挑战者节点将处理一个竞争障碍。

But no such feature is present with zero-knowledge rollups, meaning that a transaction becomes final as soon as it is added into a Nightfall block, which is then rolled up and included in a single, smaller and more efficient batch on Ethereum.

但是，零知识汇总没有任何此类功能，这意味着一旦将交易添加到夜幕板块中，交易将立即成为最终，然后将其卷起并包含在以太坊上的单个，较小，更有效的批次中。

The move away from optimistic rollups also means Nightfall users won’t need to challenge potentially incorrect transactions on Ethereum and wait out the challenging period, leading to faster transaction finality.

摆脱乐观的汇总还意味着夜幕降临用户无需挑战以太坊上潜在的不正确交易并等待具有挑战性的时期，从而导致更快的交易结局。

It is the fourth major update to Nightfall since EY launched the business-focused Ethereum layer 2 in 2019.

自EY于2019年推出了以业务为重点的以太坊第2层以来，这是夜幕降临的第四次重大更新。

Nightfall enables the firm’s business partners to transfer tokens privately using the security of Ethereum while being cheaper than the base network. It is also used to identify and bind a verified identity to a public key through digital signatures in a bid to mitigate counterparty risk.

NightFall使公司的业务合作伙伴能够使用以太坊的安全性私下转移令牌，同时比基本网络便宜。它还用于通过数字签名来识别并将经过验证的身份绑定到公共密钥，以减轻对手风险。

Recently, the firm has been advising firms in Hong Kong on how to use blockchain for cross-border payments.

最近，该公司一直在向香港提供有关如何使用区块链进行跨境支付的建议。

Earlier this year, Nightfall was one of the few blockchains to remain unaffected by the US Treasury’s Office of Foreign Assets Control (OFAC) sanctions on crypto mixing service Tornado Cash.

今年早些时候，夜幕降临是为数不多的对加密货币服务龙卷风现金的美国财政部外国资产控制办公室（OFAC）制裁（OFAC）制裁的区块链之一。

At the time, Brody said the sanctions had a “chilling effect” on legitimate business user interest in Nightfall.

当时，布罗迪说，这些制裁对夜幕降临的合法企业用户的兴趣产生了“令人毛骨悚然的影响”。

“We long ago took steps to make Nightfall unattractive to bad actors, since it cannot be used anonymously. But the removal of OFAC sanctions will really help people feel comfortable that using a privacy technology will not be risky.”

“我们很久以前就采取了措施使夜幕降临对不良演员的吸引力，因为不能匿名使用它。但是，删除OFAC制裁确实会帮助人们感到自在，因为使用隐私技术不会冒险。”

Nightfall’s code is open source on GitHub but it remains a permissioned blockchain for EY’s customer base, placing it in competition with the likes of the IBM-backed Hyperledger Fabric, R3 Corda and the Consensus-built Quorum.

NightFall的代码是GitHub上的开源代码，但它仍然是EY客户群的许可区块链，使其与IBM支持的HyperLeDger Fabric，R3 Corda和Comesensus Buolum Foorum竞争。

Brody added that EY’s blockchain team is now working toward “a single environment that supports payments, logic, and composability.”

Brody补充说，EY的区块链团队现在正在致力于“支持付款，逻辑和合成性的单一环境”。

Currently, the firm requires Nightfall and Starlight, a tool that can change smart contract code to enable zero-knowledge proofs “to enable complex multiparty business agreements under privacy.”

目前，该公司需要夜幕降临和星光，该工具可以更改智能合约代码以实现零知识证明“在隐私下启用复杂的多方商业协议”。

“We’ll spend some time supporting Nightfall_4 deployments initially. Then we’ll move on to the development of Nightfall_5.”

“我们将花一些时间支持NightFall_4部署。然后，我们将继续进行Nightfall_5的开发。”
