Incognito Chain is a monero-style zero knowledge sidechain. You can use for example DAI in a complete private and anonymous way.
If you want to help run the network, secure, and earn fees - there's a deal on the table until 16th of May.
The ready-to-work nodes sold by Incognito are now available for 199 pDAI - note the "p".
That's the privacy version run on the Incognito chain!
The full how-to buy is posted on the incognito forum
Definitely a fun little project if you're interested in the deeper blockchain tech.
