1. Tornado Cash

Tornado Cash is a private transaction tool that uses zero-knowledge proof (ZKP) technology, especially zk-SNARKs, to achieve transaction anonymity. The basic working principle is currency mixing. Due to its private transaction characteristics, Tornado Cash is often associated with hacking attacks and money laundering. SlowMist reported last year that Tornado Cash received nearly 75% of the total money laundered on the Ethereum network.

Tornado Cash has also been involved in regulatory troubles recently. On August 24, the US Department of Justice arrested Roman Storm, the co-founder of Tornado Cash, and Roman Storm and Roman Semenov, another co-founder of Tornado Cash, were charged with conspiracy to launder money, violating sanctions, and operating without a license.
