Ev-Trust: A Strategy Equilibrium Trust Mechanism for Evolutionary Games in LLM-Based Multi-Agent Services

This paper introduces Ev-Trust, a novel trust mechanism designed to enhance secure and cooperative interactions within LLM-based multi-agent systems. Grounded in evolutionary game theory, Ev-Trust dynamically adjusts trust levels based on direct and indirect feedback, guiding agents towards stable, high-quality interaction equilibria. It effectively mitigates malicious behaviors like deception and fraud in decentralized agentic service webs, significantly improving collective revenue and system robustness without requiring central authority. The mechanism is proven theoretically stable and validated experimentally across various scenarios.

Executive Impact: Enhancing Trust & Performance in LLM Agents

Ev-Trust offers a robust solution for fostering trustworthy interactions in emerging LLM-based multi-agent ecosystems, ensuring system resilience and efficiency while combating malicious behaviors. Its decentralized nature aligns with the future of autonomous AI, reducing reliance on manual oversight.

Trust Mechanisms

Ev-Trust redefines trust as a dynamic, self-organizing process within LLM-based multi-agent systems. It integrates direct and indirect trust into agents' expected revenue functions, creating a bidirectional feedback loop that drives strategic adaptation. Unlike traditional static or centralized reputation systems, Ev-Trust ensures that even if malicious agents emerge, the dominant cooperative strategy remains stable, ensuring long-term system robustness.

Evolutionary Game Theory

The core of Ev-Trust is its foundation in evolutionary game theory, capturing population-level strategy evolution. The mechanism utilizes replicator dynamics equations to prove the existence and stability of cooperative equilibria, where malicious agents are naturally eliminated through long-term evolution. This theoretical underpinning ensures that the system guides agents toward stable, high-quality interaction equilibria without relying on centralized arbitration.

Decentralized Multi-Agent Systems

Ev-Trust is designed for open, decentralized LLM-based multi-agent environments, where autonomous agents interact, reason, and plan. It addresses critical challenges like deception, fraud, and misinformation by providing a mechanism for agents to evaluate reliability and capabilities of their peers. The system supports dynamic group formation and agent mobility, allowing agents to adaptively adjust strategies and reinforce high-quality collaboration.

Ev-Trust Workflow

Agents Form Groups & Define Objectives
Requestor Publishes Service Request (with Trust-based Payment)
Provider Chooses Strategy (HQ/LQ/F/D based on Trust & Revenue)
Service Execution & Mutual Evaluation (Trust Update)
Agents Choose to Join/Leave Groups
System Returns to Next Round

Comparison of Trust Mechanisms

Feature Ev-Trust Traditional Systems (e.g., EigenTrust, BRS)
Trust Model Dynamic, Evolutionary Game Theory based (Direct + Indirect Trust, Expected Revenue) Static, Reputation-based (Transitive Aggregation, Bayesian)
Malicious Behavior Mitigation Naturally eliminated through strategy evolution, strong suppression Struggles to recover trust, weaker suppression effects
Equilibrium Locally asymptotically stable fixed points, high-quality interactions Often unstable, susceptible to manipulation
Central Authority Decentralized, no central arbitration needed Often requires manual control or centralized arbitration
Collective Revenue Steadily increases and stabilizes towards optimal No discernible upward trend, unstable

Case Study: Agentic Service Web

In a simulation of a decentralized 'Request-Response-Payment-Evaluation' service framework with 200 agents (25% initially malicious), Ev-Trust demonstrated superior performance. Over 100 rounds, it led to a 70% reduction in malicious strategies and a 25% increase in collective revenue. Normal agents exhibited the longest survival period and highest trust levels, while fraudulent agents faced severe penalties and reduced interaction opportunities, confirming the mechanism's efficacy in real-world LLM-driven open service interactions.

Key Takeaway: Ev-Trust successfully guides LLM agents towards cooperative, high-trust environments, even with initial malicious presence, proving its practical utility for the Agentic Web.
