论文摘要
自从Nakamoto于2009年首次推出比特币以来，分散的数字货币长期以来一直对学术界和行业引起了重大兴趣。直到今天，互联网上有3000多个不同的加密货币。除了确保基本的正确性外，每个人都依靠数学音质和加密智慧来提供独特的属性。对加密货币的普遍不信任是，它们通过在付款中使用随机生成的钱包地址替换人们的现实身份来提供完全匿名。但是，在公共分类账的下，这种“化名”很容易爆发。许多攻击都通过观察交易模式或网络交互来展示使人们脱颖而出的方法。因此，加密货币的可及性已成为研究界的流行话题。本报告回顾了现有方案的一部分列表，并描述了替代实现Eth-Tumbler。 Eth-Tumbler使用分层加密和多个签名，因此有效地将用户隐藏在K匿名性下。
Since the initial launch of Bitcoin by Satoshi Nakamoto in 2009, decentralized digital currencies have long been of major interest in both the academia and the industry. Till today, there are more than 3000 different cryptocurrencies over the internet. Each one relies on mathematical soundness and cryptographic wit to provide unique properties in addition to securing basic correctness. A common misbelief for cryptocurrencies is that they provide complete anonymity by replacing people's real-life identity with a randomly generated wallet address in payments. However, this "pseudonymity" is easily breakable under the public ledger. Many attacks demonstrate ways to deanonymize people through observing the transaction patterns or network interactions. Thus, cryptocurrency fungibility has become a popular topic in the research community. This report reviews a partial list of existing schemes and describes an alternative implementation, Eth-Tumbler. Eth-Tumbler utilizes layered encryption and multiple signatures and thus efficiently hides a user under k-anonymity.
