The privacy features of Tezos are quite robust and can be used in various ways. The most popular feature is the airgap, which is a method of isolating a computer from any external network or device, thus making it much harder for any malicious actors to gain access to the data stored on the computer. This is particularly useful for storing sensitive information such as cryptocurrency. Additionally, Tezos also has a feature called Sapling which is a privacy-focused smart contract that allows users to send and receive funds without revealing their identity. This is especially useful for those who want to keep their financial activities private. With the recent news of the Tornado Cash BS, it is important to note that the privacy features of Tezos are still intact and can be used to protect user data.
