Haaroon Yousaf, George Kappos, Sarah Meiklejohn

TL;DR
This paper investigates the ability to trace cryptocurrency transactions across multiple ledgers, using data from ShapeShift and various blockchains, to understand patterns and potential illicit activities.
Contribution
It introduces new heuristics and link types for cross-ledger transaction tracing and analyzes cross-currency trade patterns using real-world data.
Findings
Developed heuristics for linking transactions across ledgers
Identified common patterns in cross-currency trades
Assessed the potential for criminal or profit-driven use
Abstract
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…
