论文摘要
作为支持智能合约的最流行的无许可区块链，以太坊允许任何用户在其上创建帐户。但是，并非所有帐户都很重要。例如，可以删除由于攻击而引起的帐户。在本文中，我们对可删除的帐户进行了首次调查，该调查可以删除，以节省系统资源甚至用户的资金（即ETH或GAS）。特别是，我们提出并开发了一种名为Glaser的新颖工具，该工具分析了以太坊的状态数据库，以发现五种可擦除帐户。实验结果表明，Glaser可以准确透露508,482个可擦除帐户，这些帐户导致用户浪费了超过1.06亿美元。格拉瑟（Glaser）可以帮助停止由这些检测到的账户造成的进一步经济损失。此外，格拉瑟（Glaser）通过图形分析来表征与检测到的可擦除帐户相关的攻击/行为。
Being the most popular permissionless blockchain that supports smart contracts, Ethereum allows any user to create accounts on it. However, not all accounts matter. For example, the accounts due to attacks can be removed. In this paper, we conduct the first investigation on erasable accounts that can be removed to save system resources and even users' money (i.e., ETH or gas). In particular, we propose and develop a novel tool named GLASER, which analyzes the State DataBase of Ethereum to discover five kinds of erasable accounts. The experimental results show that GLASER can accurately reveal 508,482 erasable accounts and these accounts lead to users wasting more than 106 million dollars. GLASER can help stop further economic loss caused by these detected accounts. Moreover, GLASER characterizes the attacks/behaviors related to detected erasable accounts through graph analysis.
