Cardano网络缓解DDoS攻击，继续稳定运行

周二晚间，卡尔达诺网络遭遇了分布式拒绝服务（DDoS）攻击，此次攻击的特点是旨在破坏其运营的恶意活动大幅增加。

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.

卡尔达诺（ADA）于 3 月 14 日遭遇分布式拒绝服务（DDoS）攻击，但区块链强大的机制有效地应对了威胁，确保网络在整个过程中保持运行和稳定。

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 首席技术官 @ElRaulito_cnft 表示，这次攻击从区块 10,487,530 开始，每笔交易执行 194 个 REWARD 类型的智能合约，每笔交易花费 0.9 ADA。该策略旨在通过用这些复杂的交易填充每个块来使网络过载，从而造成积压并降低网络性能。

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

“通过这种方式，他们可以发送大笔交易，同时花费尽可能少的金额，”@ElRaulito_cnft 解释道。

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.

卡尔达诺开发公司 Anastasia 创始人 Philip Disarro 在消除威胁方面发挥了关键作用，他透露，在阅读了 Disarro 在 X 上的公开回应后，攻击者的活动受到了限制。

“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 在阅读我的推文后停止了攻击，以保护他的资金。可惜的是，他们来得太晚了，对他们资金的掠夺已经在进行中。谢谢白痴的免费钱。真正具有标志性的是，可能想要破坏生态系统的攻击者实际上最终捐赠给了我们在 Anastasia Labs 所做的开源智能合约开发工作并资助了 Midgard，”Disarro 通过 X 解释道。

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.

卡尔达诺社区密切关注事态的发展。卡尔达诺生态系统中著名的内容创作者 Big Pey 通过 X 向社区保证，他表示：“今天有人试图对卡尔达诺进行 DDOS。几乎没有发生任何事情，网络也没有崩溃。 ADA 具有弹性。”这种情绪得到了整个社区的响应，突显了人们对网络稳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 创始人 Jason Matias 直观地描述了 DDoS 攻击对网络运营的影响。

“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.

“这就是卡尔达诺现在遭受的 DDoS 攻击。灰色齿轮图标是某人发送的垃圾邮件交易，会创建更大、更难以处理的区块。”Matias 指出，并澄清了交易在网络监控工具中的视觉呈现方式。

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.

卡尔达诺使用扩展的未花费交易输出（eUTxO）模型进一步减轻了 DDoS 攻击的影响，该模型与以太坊等其他主要区块链使用的基于账户的模型有很大不同。

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，每笔交易输出不仅包含一个值，还包含一个定义资金下一步如何使用的脚本，这使得协议能够独立处理每笔交易输出。

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.

这种架构选择可实现更好的可扩展性和安全性，因为它可以防止事务相互干扰，从而隔离 DDoS 攻击等潜在问题。每笔交易的独立处理确保影响一个交易的恶意活动不会损害其他交易的完整性，从而使网络即使在胁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.

攻击发生后，ADA 价格没有受到影响。 ADA 价格在过去 24 小时内上涨了 5%，交易价格为 0.39 美元。
