To promote value growth and to ensure secure transactions between users, the RUBI community should consist of only real people with verified identities. RUBI relies on existing users to bring in only trusted people you know in real life to participate in RUBI mining.

This is why new users can only join RUBI through referral codes sent from existing users. In addition, RUBI encourages users to constantly verify the trustworthiness of the referrer by giving more performance mining with the setting of a "Trust Circle" (You can add up to 05 trusted people you know in fact enter your circle).

By adopting these measures, we strive to make RUBI secure from both technical aspects and interpersonal interactions.
