數以百萬計的加密貨幣在區塊鏈橋樑上陷入困境

區塊鏈情報公司Arkham 發現了多個加密地址，其中大量資金被「卡在」或「遺忘」在橋接合約中，其中包括與以太坊聯合創始人Vitalik Buterin、加密貨幣交易所Coinbase 和DeFi 鯨魚相關的錢包。 Arkham 的分析顯示，屬於 Buterin 的價值超過 100 萬美元的以太幣以及與 Bofur Capital 相關的價值 180 萬美元的打包比特幣已長時間無法訪問。此外，Coinbase 試圖將 75,000 美元的 USDC 轉入以太坊，但至今無人認領。

Cryptomillions Languish in Limbo on Blockchain Bridges, Arkham Intelligence Reveals

阿卡漢情報公司透露，區塊鏈橋樑上的加密貨幣百萬美元陷入困境

Blockchain intelligence firm Arkham Intelligence has uncovered a startling revelation: millions of dollars worth of cryptocurrency assets are currently "stuck" or "forgotten" in two major bridge contracts on the Ethereum blockchain.

區塊鏈情報公司 Arkham Intelligence 發現了一個驚人的消息：價值數百萬美元的加密貨幣資產目前被「卡在」或「遺忘」在以太坊區塊鏈上的兩個主要橋樑合約中。

Arkham's findings, published in an April 22 X post, shed light on a significant issue affecting the rapidly growing decentralized finance (DeFi) ecosystem. Cross-chain bridges, which enable the transfer of assets between different blockchains, have emerged as essential infrastructure for the interconnectedness of Web3. However, Arkham's research exposes the potential pitfalls associated with these bridges.

Arkham 的研究結果發表在 4 月 22 日的一篇文章中，揭示了影響快速增長的去中心化金融 (DeFi) 生態系統的一個重大問題。跨鏈橋能夠實現不同區塊鏈之間的資產轉移，已成為 Web3 互連的重要基礎設施。然而，阿卡姆的研究暴露了與這些橋樑相關的潛在陷阱。

According to Arkham, multiple identified crypto addresses hold substantial sums of money, ranging from six to seven figures, that have been trapped in bridge contracts for extended periods. These accounts include wallets linked to notable figures in the crypto industry, such as Ethereum co-founder Vitalik Buterin and cryptocurrency exchange Coinbase.

據 Arkham 稱，多個已識別的加密地址持有大筆資金，金額從六位數到七位數不等，這些資金已長期被困在橋樑合約中。這些帳戶包括與加密行業知名人士相關的錢包，例如以太坊聯合創始人 Vitalik Buterin 和加密貨幣交易所 Coinbase。

To substantiate their findings, Arkham provided screenshots of fund transfers to and from the Arbitrum and Optimism bridges. One particularly striking example is a wallet that received 50 Ether (ETH) from Buterin, which has had $1.05 million stuck in the Optimism bridge for seven months. If the address is indeed owned by Buterin, it would represent a small fraction of his vast cryptocurrency portfolio, estimated at $789 million by Arkham.

為了證實他們的發現，Arkham 提供了 Arbitrum 和 Optimism 橋之間資金轉帳的螢幕截圖。一個特別引人注目的例子是一個從 Buterin 收到 50 以太幣 (ETH) 的錢包，該錢包已在 Optimism 橋上滯留了 7 個月，價值 105 萬美元。如果該地址確實為 Buterin 所有，那麼它只佔他龐大的加密貨幣投資組合的一小部分，Arkham 估計該投資組合為 7.89 億美元。

However, it is important to note that the owners of these trapped funds may still possess control over their assets and have deliberately chosen to leave them there for the time being.

然而，值得注意的是，這些被困資金的所有者可能仍然擁有對其資產的控制權，並故意選擇暫時將其留在那裡。

Cross-chain bridges play a pivotal role in modular blockchain networks like Ethereum by facilitating data availability and security on the base layer while offloading transaction responsibilities to layer 2 solutions. However, bridges have also become attractive targets for malicious actors, particularly due to potential vulnerabilities in their automated smart contracts or highly centralized validator sets.

跨鏈橋在以太坊等模組化區塊鏈網路中發揮關鍵作用，它促進基礎層的資料可用性和安全性，同時將交易責任轉移到第 2 層解決方案。然而，橋樑也成為惡意行為者的有吸引力的目標，特別是由於其自動化智慧合約或高度集中的驗證器集中的潛在漏洞。

One infamous example of this threat is the $650 million Ronin bridge hack in March 2022, orchestrated by North Korea's state-backed Lazarus Group. The hack was made possible by the group's successful acquisition of five of the nine private keys held by transaction validators on the bridge.

這種威脅的一個臭名昭著的例子是 2022 年 3 月由北韓國家支持的 Lazarus Group 策劃的價值 6.5 億美元的 Ronin 橋駭客攻擊事件。該駭客組織成功取得了橋上交易驗證器持有的九個私鑰中的五個，從而使這次駭客攻擊成為可能。

Arkham Intelligence's findings serve as a wake-up call to the blockchain industry, highlighting the urgent need for enhanced security measures and awareness of the potential risks associated with bridge contracts. As the DeFi ecosystem continues to expand, it is imperative that stakeholders, including users, developers, and bridge operators, prioritize the safety of their assets and collaborate to mitigate these vulnerabilities.

Arkham Intelligence 的調查結果為區塊鏈產業敲響了警鐘，強調迫切需要加強安全措施並提高對與橋接合約相關的潛在風險的認識。隨著 DeFi 生態系統的不斷擴展，包括用戶、開發者和橋樑營運商在內的利害關係人必須優先考慮其資產的安全，並合作緩解這些漏洞。
