As mentioned in the weekly report:
"CCTime
The version 2.0.1 of CCTime was in development.
The front-page was reconfigured, the channel was created, and the topic was gradually published.
The reward mode and betting return model of the back-end was in development.
CCTime was expected to be tested at the end of the month."
I just want to know what is the reward mode and betting return model of the back-end, any details about that? I have read the whitepaper, but I do not understand what it is, can anyone give me some explanation?
