论文摘要
拒绝服务（DOS）攻击是网络服务中日益增长的威胁。 DOS攻击的频率和强度每天都在迅速增加。加密货币市场的巨大财务潜力是DOS攻击的普遍目标。 DOS攻击事件一直在加密货币和区块链生态系统中发生。据我们所知，没有关于DOS攻击区块链生态系统的任何研究。在本文中，我们确定了区块链生态系统中的十个实体，并仔细检查了对它们的DOS攻击。我们还提供了适用于区块链服务的DOS缓解技术。此外，我们通过使用可验证的延迟功能（VDF）提出了DOS缓解技术。
Denial of Service (DoS) attacks are a growing threat in network services. The frequency and intensity of DoS attacks are rapidly increasing day by day. The immense financial potential of the Cryptocurrency market is a prevalent target of the DoS attack. The DoS attack events are kept on happening in cryptocurrencies and the blockchain ecosystem. To the best of our knowledge, there has not been any study on the DoS attack on the blockchain ecosystem. In this paper, we identify ten entities in the blockchain ecosystem and we scrutinize the DoS attacks on them. We also present the DoS mitigation techniques applicable to the blockchain services. Additionally, we propose a DoS mitigation technique by the use of verifiable delay function (VDF).
