Insured Agents: A Decentralized Trust Insurance Mechanism for Agentic Economy

2025-12-09

AI Summary

In open agent networks, LLM-based agents suffer from trustworthiness deficiencies—including hallucination, prompt injection, and tool misuse—while existing protocols lack effective trust mechanisms. Method: We propose a decentralized trust insurance framework that introduces specialized insurance agents to provide TEE-protected staking guarantees and auditing rights for operational agents; we further design a hierarchical underwriting market integrating slashable collateral, on-chain evidence adjudication, and model-drift-resilient dispute resolution. Contribution: This work pioneers the integration of insurance economics into LLM agent governance, enabling economically incentive-compatible trustworthy collaboration. It significantly enhances security and robustness of cross-network, heterogeneous agent interactions, and supports scalable deployment.

Abstract

The emerging "agentic web" envisions large populations of autonomous agents coordinating, transacting, and delegating across open networks. Yet many agent communication and commerce protocols treat agents as low-cost identities, despite the empirical reality that LLM agents remain unreliable, hallucinated, manipulable, and vulnerable to prompt-injection and tool-abuse. A natural response is "agents-at-stake": binding economically meaningful, slashable collateral to persistent identities and adjudicating misbehavior with verifiable evidence. However, heterogeneous tasks make universal verification brittle and centralization-prone, while traditional reputation struggles under rapid model drift and opaque internal states. We propose a protocol-native alternative: insured agents. Specialized insurer agents post stake on behalf of operational agents in exchange for premiums, and receive privileged, privacy-preserving audit access via TEEs to assess claims. A hierarchical insurer market calibrates stake through pricing, decentralizes verification via competitive underwriting, and yields incentive-compatible dispute resolution.
