It turns out that they have 2 types of tokens? And what are they used for?
I was at first confused with this too. It seems like the UCC token is used inside the system as a reward, and the UNS token is to use for exchange trading
And how can I earn UCC tokens?
You need to participate in their bug bounty program. Then you will become a "hunter" and you will be looking for vulnerabilities in the systems with other "hunters". Frankly, I cannot say exactly how much you will get for it
The hunter discovering the vulnerability will be given 10,000 UCC tokens unique to the platform, whilst the hunters who checked the validity of the vulnerability will be given 1500 UCC tokens each, which can be converted on our platform to tradeable UNC tokens which can be exchanged for Ethereum on a public exchange.
