U°OS Referral System

Design and implementa a referral system for U°OS network.

Key terms:

REFERRER — an account registered at u.community REFERRAL — an account that is registered through REFERRER's link

Core mechanics:

Any account registered on the U°OS network with a non-zero Importance can generate a referral link.
The maximum amount of referral links that a REFERRER generates depends on the amount of resources the REFERRER has on the U°OS network. Basically, the referral links must be backed by resources
A REFERRAL can only have one referral connection. And consequently, a REFERRAL can only have one referral connection with one REFERRER
A referral link can only be used once
A referral link has a time-to-live period
A referral reward is a set percent from UOS emission for REFERRAL based on REFERRAL's Importance
The referral system has levels. The reward amount based on the previous bullet decreasing on the distance from the REFERRER
A fee to the system account is dedcued from the referral reward
REFERRER can set up a refback — an option to issue part of the referral reward to REFERRAL
REFERRAL and REFFERER accounts automatically set a mutual FOLLOW
With the refback option enabled, REFERRAL and REFFERER accounts automatically set a mutual TRUST
REFERRER allocates additional resources to REFERRAL on registration. This incentivizes using the ref system

Impact

A ref system naturally induces the network growth.
