# Guardian Guide

This is a guide on how to become a Guardian. A Guardian is a provider operating on the Galactica blockchain. In contrast to traditional KYC and data providers, Guardians

* Empower using personal data on a blockchain
* While preserving user privacy with zero-knowledge technology
* And offering a compliance on-ramp not available on other blockchains.

This guide covers how the concept of [Zero-Knowledge KYC](/galactica-developer-documentation/galactica-concepts/zero-knowledge-kyc.md) works in practice.

This guide provides examples of both KYC and arbitrary ZK certificates. As the Galactica network grows, types of ZK certificates can cover education diplomas, property ownership, attendance certificates, copyright licences, etc.Changelog\
