# Arbitrary ZK data certificate (GIP-2)

A **Data Guardian** is an entity or service responsible for verifying various types of data provided by users. Unlike KYC Guardians, Data Guardians can handle a wide range of data types, including one's data from social networks, education diplomas, property ownership documents, attendance certificates, and copyright licenses.

## Data Certificate Inputs

GIP-2 allows any data to be contained in a Galactica zkCert. The data needs to be collected and validated by the Guardian.
