The Relative Trust Score measures how well-connected an address is to a target set (by default, the Backers group members) through the Circles trust network.
Formula
relative_score = (penetration × 0.2 + quality × 0.8) × 100
Components
Penetration Rate: What percentage of the target set can be reached?
penetration = targets_reached / total_targets
Quality Score: How close are the connections? Closer connections (fewer hops) are weighted higher.
quality = Σ(targets_at_hop_h × decay_factor_h) / targets_reached
Hop Decay Factors
Connections at different distances are weighted differently:
- Hop 0: 1.0 (direct connection)
- Hop 1: 0.9 (one step away)
- Hop 2: 0.8 (two steps away)
- Hop 3: 0.6 (three steps away)
- Hop 4: 0.4 (four steps away)
- Hop 5: 0.2 (five steps away)
