论文摘要
区块链用户的一个普遍误解是，化名保证了隐私。现实几乎相反。每个人进行的每笔交易都记录在公共分类帐中，并揭示有关其身份的信息。通过与匿名池中的其他交易“混合”交易来保护隐私的搅拌机（例如龙卷风现金），从而更加困难地将存款和从游泳池提取的撤离。不幸的是，如果用户不小心，仍然可以揭示有关匿名池中的信息。我们介绍了Tutela，这是一个基于专家启发式方法构建的应用程序，以报告以太坊地址的真正匿名性。特别是，图泰拉具有三个功能：首先，它基于相互作用历史记录将以太坊群集成在一起，以至于对于以太坊地址，我们可以确定同一实体可能拥有的其他地址；其次，它向以太坊用户展示了他们的潜在损害交易；第三，图特拉通过排除潜在折衷的交易来计算每个龙卷风现金混合器的匿名池的真实大小。可以在https://github.com/tutelalabs/tutela-app上找到Tutela的公开实现。要使用Tutela，请访问https://www.tutela.xyz。
A common misconception among blockchain users is that pseudonymity guarantees privacy. The reality is almost the opposite. Every transaction one makes is recorded on a public ledger and reveals information about one's identity. Mixers, such as Tornado Cash, were developed to preserve privacy through "mixing" transactions with those of others in an anonymity pool, making it harder to link deposits and withdrawals from the pool. Unfortunately, it is still possible to reveal information about those in the anonymity pool if users are not careful. We introduce Tutela, an application built on expert heuristics to report the true anonymity of an Ethereum address. In particular, Tutela has three functionalities: first, it clusters together Ethereum addresses based on interaction history such that for an Ethereum address, we can identify other addresses likely owned by the same entity; second, it shows Ethereum users their potentially compromised transactions; third, Tutela computes the true size of the anonymity pool of each Tornado Cash mixer by excluding potentially compromised transactions. A public implementation of Tutela can be found at https://github.com/TutelaLabs/tutela-app. To use Tutela, visit https://www.tutela.xyz.
