摘要

比特币是中本聪提出的第一个去中心化加密货币。虽然交易是在假名之间进行的,但比特币无法提供强有力的隐私保证。在某种程度上,混合币可以通过不同的技术解决这一缺点,但也会遇到灵活性、存储和匿名性问题。本文提出了一个基于环签名、一次性输出地址、CoinJoin和我们的互认委托策略的去中心化硬币混合方案CoinMingle。我们的互认委托策略简单而有效:当用户准备提交消息时,他将其委托给其他用户以匿名。CoinMingle的用户不需要预先计算。CoinMingle可以容忍不同的输入量,并在洗牌阶段堵塞个人信息的泄露。此外,CoinMingle拥有并行结构,比其他硬币混合方案更高效。

CoinMingle: A Decentralized Coin Mixing Scheme with a Mutual Recognition Delegation Strategy
Bitcoin is the first decentralized cryptocurrency proposed by Satoshi Nakamoto. Although transactions are conducted between pseudonyms, Bitcoin cannot offer strong privacy guarantees. Mixing coins, to some extent, can address this drawback through different technologies, but also meets flexibility, storage and anonymity problems. This paper proposes a decentralized coin mixing scheme CoinMingle, based on ring signature, one-time output address, CoinJoin and our mutual recognition delegation strategy. Our mutual recognition delegation strategy is simple but effective: when a user prepares to submit messages, he will delegate it to other users for anonymity. Users in CoinMingle don’t need pre-compute. And CoinMingle can tolerate different input amounts and plug the leak of personal information in shuffling phase. In addition, CoinMingle owns parallel structure which is more efficient than other coin mixing schemes.
