Insured Agents: A Decentralized Trust Insurance Mechanism for Agentic Economy

TL;DR

This paper introduces a decentralized trust insurance mechanism for autonomous agents in open networks, using insurer agents and a hierarchical market to improve reliability and verification of agent behavior.

Contribution

It proposes insured agents with stake posting and privileged audits, offering a novel, decentralized approach to trust and misbehavior verification in agentic economies.

Findings

Hierarchical insurer market calibrates stake effectively.

Privileged audits via TEEs enhance privacy and verification.

Decentralized dispute resolution incentivizes honest behavior.

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.
