## Galactica web application

The [web application](https://cassiopeia.galactica.com/) can currently be used to get your TestNet zkKYC and generate a zkProof proving its existence. On the TestNet no real data is required to pass the KYC, please use mock data where needed.

This application will be extended to support upcoming features: reputation, citizenship and governance.
