论文摘要
BISQ DAO是BISQ的核心组成部分，BISQ是一种分散的加密货币交换。 BISQ DAO的目的是分散交换的治理和财务职能。但是，通过与BISQ DAO进行互动，参与者必然将数据发布到比特币区块链上，并将其他数据广播到BISQ点对点网络。我们检查了参与者共享此数据的隐私成本。具体来说，我们使用一种新颖的地址聚类启发式方法来构建从参与者到比特币区块链上的地址的一对多映射，并使用存储在BISQ点对点网络中的数据来增强地址群集。我们表明，该技术汇总了每个参与者执行的活动：交易，投票，转移等。我们确定参与者在多个别名下运行的实例，其中一些是真实的名称。我们确定了主要的交易剂及其在双面市场中的作用。我们提出了建议，以更好地保护未来参与者的隐私。
The Bisq DAO is a core component of Bisq, a decentralized cryptocurrency exchange. The purpose of the Bisq DAO is to decentralize the governance and finance functions of the exchange. However, by interacting with the Bisq DAO, participants necessarily publish data to the Bitcoin blockchain and broadcast additional data to the Bisq peer-to-peer network. We examine the privacy cost to participants in sharing this data. Specifically, we use a novel address clustering heuristic to construct the one-to-many mappings from participants to addresses on the Bitcoin blockchain and augment the address clusters with data stored within the Bisq peer-to-peer network. We show that this technique aggregates activity performed by each participant: trading, voting, transfers, etc. We identify instances where participants are operating under multiple aliases, some of which are real-world names. We identify the dominant transactors and their role in a two-sided market. We conclude with suggestions to better protect the privacy of participants in the future.
