Casper 网络因安全漏洞暂时停止后恢复运行

Casper 网络因安全漏洞而暂时停止后已恢复运行。 UTC 时间 7 月 31 日下午 3:18，64 名验证者一致同意恢复验证

After a brief pause in response to a security breach, The Casper Network has resumed operations. On July 31 at 3:18 pm UTC, 64 validators agreed to resume validation, representing 85% of the CSPR to staked on the network.

在因安全漏洞而短暂暂停后，Casper Network 已恢复运营。世界标准时间 7 月 31 日下午 3:18，64 个验证者同意恢复验证，相当于质押在网络上的 CSPR 的 85%。

“The network has fully recovered and is now fully operational,” an update on X reads.

X 上的更新写道：“网络已完全恢复，现已全面投入运行。”

The security incident was resolved through a concerted effort involving validators, engineers and other stakeholders in a decentralized fashion.

通过验证者、工程师和其他利益相关者的共同努力，以去中心化的方式解决了安全事件。

Technical challenges in the upgrade

升级中的技术挑战

The pause in network operations presented a technical challenge, especially since it occurred in the middle of an active era rather than at the end, the Casper team’s update noted.

Casper 团队的更新指出，网络运营的暂停带来了技术挑战，特别是因为它发生在活跃时代的中期而不是末期。

To address this, two blocks containing four transactions were removed, essentially orphaning these transactions and their effects on the blockchain.

为了解决这个问题，删除了包含四笔交易的两个区块，基本上孤立了这些交易及其对区块链的影响。

The upgrade process involved deploying a new Casper-node binary and standard configuration files.

升级过程涉及部署新的 Casper 节点二进制文件和标准配置文件。

Following the network pause, validators had to manually initiate the upgrade and implement the new version, a process that required real-time synchronization. Additionally, a tool was created to scan the entire blockchain from its inception to the present, aiming to ensure that no other instances of exploitation had occurred.

网络暂停后，验证者必须手动启动升级并实施新版本，这个过程需要实时同步。此外，还创建了一个工具来扫描整个区块链从诞生到现在的整个过程，旨在确保没有发生其他利用情况。

Validators approve node restart

验证者批准节点重启

With the validators’ consent, the nodes were restarted, removing the two problematic blocks and applying the necessary global state changes. Once 66.7% or more of the consensus stake reached this point, the network was unpaused and block creation resumed.

在验证者的同意下，节点被重新启动，删除了两个有问题的块并应用了必要的全局状态更改。一旦 66.7% 或更多的共识权益达到这一点，网络就会取消暂停并恢复区块创建。

As the Casper network resumes operations, WazirX, a well-known Indian cryptocurrency exchange that also suffered a security breach that resulted in the theft of approximately $230 million, has announced a strategy for user fund recovery.

随着Casper网络恢复运营，同样遭受安全漏洞导致约2.3亿美元被盗的印度知名加密货币交易所WazirX宣布了用户资金追回策略。

Unlike WazirX, which reported no evidence of compromised signer machines in its preliminary investigation of the July 18 hack, the Casper team has made significant progress in identifying the root cause of the breach.

WazirX 在对 7 月 18 日黑客攻击的初步调查中没有报告签名者机器受到损害的证据，与此不同的是，Casper 团队在确定泄露的根本原因方面取得了重大进展。

Other prominent crypto hack victims in July include algorithmic protocol Compound Finance ($24 million), bridging protocol Li​.Fi ($10 million), decentralized AI protocol Bittensor and liquidity provider Rho Markets ($8 million each).

7 月份其他著名的加密货币黑客受害者包括算法协议 Compound Finance（2400 万美元）、桥接协议 Li​.Fi（1000 万美元）、去中心化 AI 协议 Bittensor 和流动性提供商 Rho Markets（各 800 万美元）。

Cointelegraph reached out to the Casper network team for more information on its root cause analysis but had yet to receive feedback at the time of publication.

Cointelegraph 联系了 Casper 网络团队，以获取有关其根本原因分析的更多信息，但截至发稿时尚未收到反馈。
