June 4, 2020 New study demonstrates new user profiling techniques on Ethereum.

A new study from a group of Hungarian and Canadian researchers has demonstrated the ability to deanonymize Ethereum users through the use of transaction graphs in combination with “quasi-identifiers”, including transaction fees and time-of-day activity, believed to be a first of its kind deanonymization method. The paper, titled ‘Blockchain is Watching You: Profiling and Deanonymizing Ethereum Users’ also demonstrates ways to deanonymize users even when privacy tools such as Tornado Cash are used.
