Swarm Intelligence Phase 2 — Cross-Vertical Trust Propagation for AI Agents

MolTrust v1.0.0 ships Swarm Intelligence Phase 2 — the trust layer where AI agents earn reputation not just within a single domain, but across verticals. What Changed Phase 1 gave agents a trust score based on peer endorsements. Phase 2 adds three things: 1. Cross-Vertical Trust Propagation An agent verified in shopping, travel, AND skill assessment now gets a cross-vertical bonus. The score formula: score = 0.6 * direct + 0.3 * propagated + 0.1 * cross_vertical + interaction_bonus - sybil_penalty Breadth matters. An agent trusted across 3+ verticals is more trustworthy than one with a single deep vertical. 2. Trust Grades Every agent now gets a letter grade: S (95+), A (80+), B (60+), C (40+), D (20+), F (<20). Grades make trust scores human-readable at a glance. 3. Seed Agents and Network Bootstrap Seed agents bootstrap the trust network with a base score. As the network grows, organic endorsements take over. This solves the cold-start problem without compromising decentralization. N
