跨区块链追踪加密货币资金流
文章 arXiv papers · 作者: Haaroon Yousaf et al.
总结
本文探讨能否跨不同区块链账本关联加密货币交易，拓展了在单一货币内部追踪活动的研究。研究聚焦于将一种加密货币兑换成另一种的交易服务，这类服务可能在原本彼此独立的交易历史之间建立联系。研究开发了识别跨账本关联的启发式方法，并考察跨币种兑换活动的模式。
研究证据结合了从 ShapeShift 收集的十三个月活动数据和八条区块链的信息。作者利用这些数据研究平台使用情况，并探讨相关服务是否与犯罪活动或逐利行为有关。所提供的说明没有报告具体的关联规则、测得的模式，也未说明对用户身份和动机的结论。由于区块链上的可见信息本身不能证明某个地址由谁控制，对推断出的关联和意图解释应保持不确定。
核心观点
- 跨币种兑换服务可以为追踪资金在不同区块链账本之间的流动提供路径。
- 研究开发了用于关联不同加密货币交易记录的启发式方法。
- 研究分析了为期十三个月的 ShapeShift 活动和八条区块链的数据。
- 研究考察兑换模式和平台使用情况，包括可能的犯罪动机或逐利动机。

# Tracing Transactions Across Cryptocurrency Ledgers # Tracing Transactions Across Cryptocurrency Ledgers One of the defining features of a cryptocurrency is that its ledger, containing all transactions that have evertaken place, is globally visible. As one consequenceof this degree of transparency, a long line of recent re-search has demonstrated that even in cryptocurrenciesthat are specifically designed to improve anonymity it is often possible to track money as it changes hands,and in some cases to de-anonymize users entirely. With the recent proliferation of alternative cryptocurrencies, however, it becomes relevant to ask not only whether ornot money can be traced as it moves within the ledgerof a single cryptocurrency, but if it can in fact be tracedas it moves across ledgers. This is especially pertinent given the rise in popularity of automated trading platforms such as ShapeShift, which make it effortless to carry out such cross-currency trades. In this paper, weuse data scraped from ShapeShift over a thirteen-monthperiod and the data from eight different blockchains to explore this question. Beyond developing new heuristics and creating new types of links across cryptocurrency ledgers, we also identify various patterns of cross-currency trades and of the general usage of these platforms, with the ultimate goal of understanding whetherthey serve a criminal or a profit-driven agenda.
