# Cassiopeia Release Notes

## Status

Cassiopeia is Galactica's third testnet. It is an Arbitrum Orbit L2 chain with EVM smart contracts and settlement to Ethereum Sepolia.

The main goals of the Testnet are:

* Give users and developers simple access to [learn](https://docs.galactica.com/galactica-developer-documentation/) about and [build](https://github.com/Galactica-corp) on the new possibilities offered by Galactica. Get experience to leverage zero-knowledge disclosures, sybil resistance and  compliant privacy for your use-cases and business ideas.
* Users can experience the zero-knowledge KYC solution.
* Collect [community feedback](https://www.youtube.com/watch?v=BZNBlpTGjSc\&t=2208s) to figure out how Galactica works best for it's users.
* Test Galactica's technology and user experience
* Decentralize validation and block building
* Benchmark the system

## Disclaimer

There is still a lot to be learned about unlocked possibilities, limitations, usability, technical implications and use cases. The feedback from the testnet will accelerate this process and focus it on the users' needs.\
The concept, code and documentation of Galactica will change accordingly to iterate and improve towards the best Galactica can become.
