The dydx network was down for nine hours and 32 minutes, according to dYdX’s status page, after which it resumed block production following the developers deploying a fix to the issue.

根据 dYdX 的状态页面，dydx 网络停机了 9 小时 32 分钟，之后在开发人员部署了针对该问题的修复程序后，该网络恢复了区块生产。

The developer team said it had made a critical update to the network after a bug was discovered in the v4.0 code base.

开发团队表示，在 v4.0 代码库中发现错误后，他们对网络进行了重要更新。

The community voted almost unanimously to approve the v4.0 upgrade, which introduced protocol improvements, new features, and the ability for community proposals to slash validators for misconduct.

社区几乎一致投票批准了 v4.0 升级，该升级引入了协议改进、新功能以及社区提案削减不当行为验证者的能力。

“This would enable the MEV [Maximal Extractable Value] Slashing Committee to create a governance proposal to slash validators engaged in malicious MEV,” stated the proposal.

该提案表示：“这将使 MEV [最大可提取价值] 削减委员会能够制定一项治理提案，以削减参与恶意 MEV 的验证者。”

Dimitar Petkov, the DeFi technical project lead in dYdX’s operations subDAO, told Blockworks that the chain halt was caused by a corruption in the network’s state during the upgrade because the wrong version of a bug fix in Cosmos’ IAVL library was included in the software release.

dYdX 运营 subDAO 的 DeFi 技术项目负责人 Dimitar Petkov 告诉 Blockworks，链停顿是由于升级期间网络状态损坏造成的，因为软件版本中包含了 Cosmos IAVL 库中错误修复的错误版本。

It is worth noting that the dYdX DEX remained functional through the chain halt, but some users encountered issues while making transfers. 

值得注意的是，dYdX DEX在断链期间仍然保持功能，但部分用户在转账时遇到了问题。

dYdX’s native token also remained surprisingly resilient to news of the outage, gaining 3.44% in the last 24 hours.

dYdX 的原生代币也对中断消息保持了惊人的弹性，在过去 24 小时内上涨了 3.44%。

Last year, dYdX announced that it would be building v4 of its protocol as a standalone Cosmos chain. The network entered its beta mainnet in November, and in January began to offer liquid staking to token holders.

去年，dYdX 宣布将构建其协议 v4 作为独立的 Cosmos 链。该网络于 11 月进入测试版主网，并于 1 月开始向代币持有者提供流动性质押。
