Backward Endorsement Reward Propagation

Enforcing Trust Accountability with Backward Propagation

arXiv:2606.08851v1 Announce Type: new Abstract: Trust and reputation management underpins reliable interactions in distributed networks, yet existing trust models rely solely on forward propagation of interaction-based trust signals. They lack robust mechanisms to enforce accountability for the propagated trust signals when negative interactions occur. In addition, such models often fail to initialize newly joined nodes with sparse interaction history, leading to the cold-start problem.
