Casper 網路因安全漏洞暫時停止後恢復運行

Casper 網路因安全漏洞而暫時停止後已恢復運作。 UTC 時間 7 月 31 日下午 3:18，64 位驗證者一致同意恢復驗證

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.

在因安全漏洞而短暫暫停後，Casper Network 已恢復營運。世界標準時間 7 月 31 日下午 3:18，64 個驗證者同意恢復驗證，相當於質押在網路上的 CSPR 的 85%。

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

X 上的更新寫道：“網路已完全恢復，現已全面投入運行。”

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

透過驗證者、工程師和其他利害關係人的共同努力，以去中心化的方式解決了安全事件。

Technical challenges in the upgrade

升級中的技術挑戰

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 團隊的更新指出，網路營運的暫停帶來了技術挑戰，特別是因為它發生在活躍時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.

為了解決這個問題，刪除了包含四筆交易的兩個區塊，基本上孤立了這些交易及其對區塊鏈的影響。

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

升級過程涉及部署新的 Casper 節點二進位和標準設定檔。

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.

網路暫停後，驗證者必須手動啟動升級並實施新版本，這個過程需要即時同步。此外，還創建了一個工具來掃描整個區塊鏈從誕生到現在的整個過程，旨在確保沒有發生其他利用情況。

Validators approve node restart

驗證者批准節點重啟

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.

在驗證者的同意下，節點被重新啟動，刪除了兩個有問題的區塊並應用了必要的全域狀態變更。一旦 66.7% 或更多的共識權益達到這一點，網路就會取消暫停並恢復區塊創建。

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.

隨著Casper網路恢復運營，同樣遭受安全漏洞導致約2.3億美元被盜的印度知名加密貨幣交易所WazirX宣布了用戶資金追回策略。

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 7 月 18 日駭客攻擊的初步調查中沒有報告簽署者機器受到損害的證據，與此不同的是，Casper 團隊在確定洩漏的根本原因方面取得了重大進展。

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 月其他著名的加密貨幣駭客受害者包括演算法協議Compound Finance（2,400 萬美元）、橋接協議Li.Fi（1000 萬美元）、去中心化AI 協議Bittensor 和流動性提供商Rho Markets（各800 萬美元）。

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.
