论文摘要
作为最大的初始硬币产品项目，Eosio对加密货币市场引起了极大的兴趣。尽管它的知名度和繁荣（例如，从2018年6月8日至2020年8月5日进行了26,311,585,008代币交易），但几乎没有工作调查EOSIO代币生态系统。为了填补这一空白，我们是第一个对EOSIO代币生态系统进行系统研究的人，通过对整个链链EOSIO数据进行全面的图形分析（接近1.35亿个块）。我们构建令牌创建者图形，令牌合同创建者图，令牌持有器图和令牌传输图，以表征令牌创建者，持有者和传输活动。通过图形分析，我们获得了许多有见地的发现，并观察到了一些异常的交易模式。此外，我们提出了一种伪造的检测算法，以识别伪造用户或假交易产生的令牌，并分析其相应的操作行为。评估结果还证明了我们算法的有效性。
Being the largest Initial Coin Offering project, EOSIO has attracted great interest in cryptocurrency markets. Despite its popularity and prosperity (e.g., 26,311,585,008 token transactions occurred from June 8, 2018 to Aug. 5, 2020), there is almost no work investigating the EOSIO token ecosystem. To fill this gap, we are the first to conduct a systematic investigation on the EOSIO token ecosystem by conducting a comprehensive graph analysis on the entire on-chain EOSIO data (nearly 135 million blocks). We construct token creator graphs, token-contract creator graphs, token holder graphs, and token transfer graphs to characterize token creators, holders, and transfer activities. Through graph analysis, we have obtained many insightful findings and observed some abnormal trading patterns. Moreover, we propose a fake-token detection algorithm to identify tokens generated by fake users or fake transactions and analyze their corresponding manipulation behaviors. Evaluation results also demonstrate the effectiveness of our algorithm.
