StockAppps Financial analyst, Edith Reads, says,” As control and surveillance of traditional finance tightens, the allure of digital assets will only grow. Decentralized protocols like Tornado Cash offer a powerful way to keep transactions private, and we expect their usage will continue to increase.”

Tornado Cash is a decentralized protocol that allows users to send ETH and ERC20 tokens without revealing their identity. The protocol uses zero-knowledge proofs to allow users to mix their assets in a completely trustless manner. Tornado Cash is the most popular mixing service currently available.

There are a number of protocols vying for a share of the market for private transaction services. The six protocols that have processed the most value are:

Messier 87
