Cardano網路緩解DDoS攻擊，持續穩定運行

週二晚間，卡爾達諾網路遭遇了分散式阻斷服務（DDoS）攻擊，這次攻擊的特點是旨在破壞其營運的惡意活動大幅增加。

Cardano (ADA) encountered a distributed denial of service (DDoS) attack on March 14, but the blockchain’s robust mechanisms effectively countered the threat, ensuring the network remained operational and stable throughout the ordeal.

卡爾達諾（ADA）於 3 月 14 日遭遇分散式阻斷服務（DDoS）攻擊，但區塊鏈強大的機制有效地應對了威脅，確保網路在整個過程中保持運作和穩定。

The attack, which began at block 10,487,530, saw each transaction executing 194 smart contracts of the REWARD type and spending 0.9 ADA per transaction, according to Fluid Token Chief Technology Officer @ElRaulito_cnft. This strategy aimed to overload the network by filling each block with these complex transactions, creating a backlog and degrading the network’s performance.

Fluid Token 技術長 @ElRaulito_cnft 表示，這次攻擊從區塊 10,487,530 開始，每筆交易執行 194 個 REWARD 類型的智能合約，每筆交易花費 0.9 ADA。該策略旨在透過用這些複雜的交易填充每個區塊來使網路過載，從而造成積壓並降低網路效能。

“In this way, they can send large transactions while spending the least possible amount,” @ElRaulito_cnft explained.

「透過這種方式，他們可以發送大筆交易，同時花費盡可能少的金額，」@ElRaulito_cnft 解釋道。

Cardano development firm Anastasia founder Philip Disarro, who played a key role in neutralizing the threat, revealed that the attacker’s activities were curtailed after reading Disarro’s public response on X.

卡爾達諾開發公司 Anastasia 創始人 Philip Disarro 在消除威脅方面發揮了關鍵作用，他透露，在閱讀了 Disarro 在 X 上的公開回應後，攻擊者的活動受到了限制。

“DDOSer halted his attack after reading my tweet in an effort to protect his funds. Alas, they were too late and the pillaging of their funds is already in progress. Thanks for the free money moron. Truly iconic that the attacker who presumably wanted to damage the ecosystem actually ended up donating to the open-source smart contract development work we do at Anastasia Labs & funding Midgard,” Disarro explained via X.

「DDOSer 在閱讀我的推文後停止了攻擊，以保護他的資金。可惜的是，他們來得太晚了，對他們資金的掠奪已經在進行中。謝謝白痴的免費錢。真正具有標誌性的是，可能想要破壞生態系統的攻擊者實際上最終捐贈給了我們在 Anastasia Labs 所做的開源智能合約開發工作並資助了 Midgard，」Disarro 透過 X 解釋道。

The Cardano community closely monitored the situation as it unfolded. Big Pey, a prominent content creator within the Cardano ecosystem, reassured the community via X, stating, “Someone tried to DDOS Cardano today. Barely anything happened, and the network didn’t crash. ADA is resilient.” This sentiment was echoed across the community, highlighting confidence in the network’s stability and security measures.

卡爾達諾社區密切關注事態的發展。卡爾達諾生態系統中著名的內容創作者 Big Pey 透過 X 向社群保證，他表示：「今天有人試圖對卡爾達諾進行 DDOS。幾乎沒有發生任何事情，網路也沒有崩潰。 ADA 具有彈性。這種情緒得到了整個社區的回應，突顯了人們對網路穩定性和安全措施的信心。

The Art of Selling Art founder Jason Matias visually described the impact of the DDoS attack on network operations.

Art of Selling Art 創辦人 Jason Matias 直觀地描述了 DDoS 攻擊對網路運作的影響。

“This is what the DDoS attack on Cardano looks like right now. The grey gear icons are the spam transactions that someone is sending, creating larger, more difficult to process blocks,” Matias noted, clarifying how the transactions visually appeared within network monitoring tools.

「這就是卡爾達諾現在遭受的 DDoS 攻擊。灰色齒輪圖示是某人發送的垃圾郵件交易，會創建更大、更難以處理的區塊。

The impact of the DDoS attack was further mitigated by Cardano’s use of the extended Unspent Transaction Output (eUTxO) model, which differs significantly from the account-based models used by other major blockchains like Ethereum.

卡爾達諾使用擴展的未花費交易輸出（eUTxO）模型進一步減輕了 DDoS 攻擊的影響，該模型與以太坊等其他主要區塊鏈使用的基於帳戶的模型有很大不同。

In the eUTxO model, each transaction output contains not only a value but also a script defining how the funds can be used next, which allows the protocol to handle each transaction output independently.

在eUTxO模型中，每筆交易輸出不僅包含一個值，還包含一個定義資金下一步如何使用的腳本，這使得協議能夠獨立處理每筆交易輸出。

This architectural choice enables better scalability and security, as it prevents transactions from interfering with each other, thereby isolating potential issues like those introduced by the DDoS attack. The independent processing of each transaction ensures that malicious activity affecting one does not compromise the integrity of others, allowing the network to maintain high throughput and reliability even under duress.

這種架構選擇可實現更好的可擴展性和安全性，因為它可以防止事務相互幹擾，從而隔離 DDoS 攻擊等潛在問題。每筆交易的獨立處理確保影響一個交易的惡意活動不會損害其他交易的完整性，從而使網路即使在脅迫下也能保持高吞吐量和可靠性。

Following the attack, the ADA price was not affected. The ADA price is up 5% in the last 24 hours, trading at $0.39.

攻擊發生後，ADA 價格沒有受到影響。 ADA 價格在過去 24 小時內上漲了 5%，交易價格為 0.39 美元。
