Cardano 发布 Node 9.0，Chang 硬分叉前的最后开发步骤

Cardano开发团队于7月8日发布了Cardano验证器节点软件的最新版本“Node 9.0”。根据Cardano创始人Charles Hoskinson于7月7日发布的YouTube视频，新软件是允许验证器节点软件的最后开发步骤。即将发生的 Chang 硬分叉。

The Cardano development team released “Node 9.0,” the newest version of the Cardano validator node software, on July 8. The new software is the final development step needed to allow the upcoming Chang hard fork to occur, according to a YouTube video released by Cardano founder Charles Hoskinson on July 7.

Cardano开发团队于7月8日发布了“Node 9.0”，这是Cardano验证器节点软件的最新版本。根据Cardano发布的YouTube视频，新软件是允许即将到来的Chang硬分叉发生所需的最后开发步骤7 月 7 日，卡尔达诺创始人查尔斯·霍斯金森 (Charles Hoskinson)。

The software was released at approximately 7 pm UTC. It “is the first node that can support crossing the 9.0 hard fork (Chang) boundary on mainnet and long-running testnets, such as PreProd,” according to its notes.

该软件于世界标准时间晚上 7 点左右发布。根据其注释，它“是第一个可以支持在主网和长期运行的测试网上（例如 PreProd）跨越 9.0 硬分叉（Chang）边界的节点”。

Hoskinson announced in a YouTube video the previous day that the software's release was imminent, stating that it would be available “next week.” He also said that “probably Monday or Tuesday, the signal for mass upgrades will come.” 70% of nodes will need to vote to upgrade to the new software in order for a hard fork to occur, according to Hoskinson.

Hoskinson 前一天在 YouTube 视频中宣布该软件即将发布，并表示将在“下周”推出。他还表示，“大概周一或周二，大规模升级的信号就会到来。” Hoskinson 表示，70% 的节点需要投票升级到新软件才能发生硬分叉。

The Chang hard fork is the first step in giving Cardano fully decentralized governance, according to the development team. It begins the “Age of Voltaire” on Cardano's roadmap, a period that will see massive changes to the network's political system.

开发团队表示，Chang 硬分叉是卡尔达诺完全去中心化治理的第一步。它开启了卡尔达诺路线图上的“伏尔泰时代”，在这个时期，网络的政治体系将发生巨大变化。

These changes are outlined by the developers in Cardano Improvement Proposal 1694 (CIP 1694). According to the proposal, Chang will ultimately allow for the introduction of Delegate Representatives (DReps), who will be elected by ADA tokenholders.

开发人员在卡尔达诺改进提案 1694 (CIP 1694) 中概述了这些变化。根据该提案，Chang 最终将允许引入代表 (DReps)，该代表将由 ADA 代币持有者选举产生。

These representatives will draft a Cardano Constitution, which will become the supreme governing law of the network. After a Constitution is drafted and approved, DReps will continue to propose changes to the network in accordance with this constitution.

这些代表将起草卡尔达诺宪法，该宪法将成为网络的最高管理法律。在宪法起草并获得批准后，DReps将继续根据该宪法提出对网络的修改建议。

The Node 9.0 notes state that it will not yet “enable DRep voting and all governance actions,” as the full voting protocol will only be provided in version 10.0. However, it “supports entering the bootstrap phase of CIP-1694 in production environments.”

Node 9.0 指出，它尚未“启用 DRep 投票和所有治理操作”，因为完整的投票协议仅在 10.0 版本中提供。但是，它“支持在生产环境中进入 CIP-1694 的引导阶段”。

Block explorer Cardanoscan shows that exchanges and stake pools had not yet prepared for the hard fork at the time of publication.

Hoskinson stated in the YouTube video that he expects the hard fork to begin on “Monday or Tuesday,” indicating that the process will start on July 8-9.

Hoskinson 在 YouTube 视频中表示，他预计硬分叉将于“周一或周二”开始，这表明该过程将于 7 月 8 日至 9 日开始。

Hoskinson had previously stated that he expected the fork to occur in June, but that deadline passed about a week ago. After an attacker attempted to crash the network with a distributed denial-of-service attack, Cardano performed another node upgrade on June 26.

Hoskinson 此前曾表示，他预计分叉将于 6 月发生，但该截止日期大约一周前就过去了。在攻击者试图通过分布式拒绝服务攻击使网络崩溃后，卡尔达诺于 6 月 26 日进行了另一次节点升级。
