# Other Privacy Enhancing Technologies (PETs) used by Panther In addition to [Zero-Knowledge proofs](/docs/learn/cryptographic-primitives/zero-knowledge-proofs.md), Panther uses [*differential privacy*](https://web.cs.ucdavis.edu/~franklin/ecs289/2010/dwork_2008.pdf), [*homomorphic encryption*](https://arxiv.org/abs/2101.07078), [*Secure Multi-Party Computation*](https://www.cs.virginia.edu/~evans/pragmaticmpc/pragmaticmpc.pdf), and [*selective disclosure schemes*](https://hal.inria.fr/hal-01586575/document). Each of these mathematical and technical building blocks plays different roles in supporting the enablement of privacy, anonymity, and scalability. By drawing upon these technologies, Panther facilitates a shift in trust from regulatory frameworks and organizational practices to trustless mathematical proofs and their interpretation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.pantherprotocol.io/docs/learn/cryptographic-primitives/other-privacy-enhancing-technologies-pets-used-by-panther.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
