In a cryptocurrency with privacy e.g., zcash, where does proof generation take place? Can it happen in the client's device every time a transaction is performed?

If it happens in client's device, are there possibilities of malware compromising the privacy?

If the proof generated is compromised, then it will fail verification by anyone who tries to verify it - so it won't matter

Taking Zcash as an example, the proof is generated on the spender side. If the running environment is not trusted, two things will happen.

Malware could extract private information, such as payment value, wallet address, from the device's storage or memory.
Malware could tamper with the input of pre-compiled circuits, e.g., recipient address, public keys.

In major privacy currencies, such as haircomb, the proof generation (hashing) occurs on the client device. It is not believed a malware could compromise this in a meaningful way.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
