# Qortal Project - Official Repo
# Qortal Data Node
## Important
This code is unfinished, and we haven't had the official genesis block for the data chain yet.
Therefore it is only possible to use this code if you first create your own test chain. I would
highly recommend waiting until the code is in a more complete state before trying to run this.
