Multi-Trust-Incentives

Multi-Trust-Incentives

The major problem of private history based incentive systems is their coverage. Resolving it requires leveraging other reputable peers’ history which leads directly to the EigenTrust mechanism. Multi-Trust-Incentives try to mix both mechanisms.

Mathematical View

One-Step-Matrix

The Evaluation of Trust between peers is measured in a Matrix M. This N * N matrix defines a one-step rank among peers. All values are measured as the normalized download volume that a peer i has received from a peer j during a period of time.

Two-Step-Matrix

A two-step-matrix $M^{2}$ describes the relation in 3 levels.
