EY將其以企業為重點的以太坊2層區塊鏈夜幕降臨到零知識匯總設計

四大會計公司EY（以前是Ernst＆Young）已將其專注於企業的以太坊層區塊鏈夜幕降低為零知識匯總設計

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.

四大會計公司EY（以前是Ernst＆Young）透露了其以企業為中心的以太坊2層區塊鏈夜幕降至零知識匯總的設計變化。

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年以來，該公司一直以樂觀的滾動設計進行夜幕降臨，他說，它正在轉向ZK滾動模型，因為它變得更容易被用戶訪問，而夜幕降臨的架構正通過其第四個主要更新“ nightfall_4”來簡化。

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於4月4日宣布，還將在以太坊上看到幾乎即時的交易終結性，並通過添加新的編程語言，Anplomb和新文檔套件來越來越訪問用戶。

“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發言人告訴Cointelegraph：“體系結構的這種變化幾乎意味著最終的終止性，但它也使操作變得更加簡單，因為我們不需要挑戰者節點來保護網絡，該網絡用於檢測和糾正交易中的任何錯誤。”

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，有了樂觀的匯總，在一段時間內，交易受到挑戰，如果認為不正確，挑戰者節點將處理一個競爭障礙。

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，零知識匯總沒有任何此類功能，這意味著一旦將交易添加到夜幕板塊中，交易將立即成為最終，然後將其捲起並包含在以太坊上的單個，較小，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.

擺脫樂觀的匯總還意味著夜幕降臨用戶無需挑戰以太坊上潛在的不正確交易並等待具有挑戰性的時期，從而導致更快的交易結局。

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

自EY於2019年推出了以業務為重點的以太坊第2層以來，這是夜幕降臨的第四次重大更新。

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使公司的業務合作夥伴能夠使用以太坊的安全性私下轉移令牌，同時比基本網絡便宜。它還用於通過數字簽名來識別並將經過驗證的身份綁定到公共密鑰，以減輕對手風險。

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

最近，該公司一直在向香港提供有關如何使用區塊鏈進行跨境支付的建議。

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.

今年早些時候，夜幕降臨是為數不多的對加密貨幣服務龍捲風現金的美國財政部外國資產控制辦公室（OFAC）制裁（OFAC）制裁的區塊鏈之一。

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

當時，布羅迪說，這些制裁對夜幕降臨的合法企業用戶的興趣產生了“令人毛骨悚然的影響”。

“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.”

“我們很久以前就採取了措施使夜幕降臨對不良演員的吸引力，因為不能匿名使用它。但是，刪除OFAC制裁確實會幫助人們感到自在，因為使用隱私技術不會冒險。”

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的代碼是GitHub上的開源代碼，但它仍然是EY客戶群的許可區塊鏈，使其與IBM支持的HyperLeDger Fabric，R3 Corda和Comesensus Buolum Foorum競爭。

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

Brody補充說，EY的區塊鏈團隊現在正在致力於“支持付款，邏輯和合成性的單一環境”。

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，該公司需要夜幕降臨和星光，該工具可以更改智能合約代碼以實現零知識證明“在隱私下啟用複雜的多方商業協議”。

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

“我們將花一些時間支持NightFall_4部署。然後，我們將繼續進行Nightfall_5的開發。”
