What is Agent Reputation?

1 min read Updated

Agent reputation is a quantifiable measure of an AI agent's trustworthiness and reliability, based on its history of behavior — including transaction success rates, policy compliance, uptime, and quality of service delivery.

WHY IT MATTERS

In an economy where agents transact autonomously, how do you know which agents to trust? Agent reputation provides a track record. An agent that has executed 10,000 transactions without a policy violation over 6 months is more trustworthy than one deployed yesterday.

Reputation can be on-chain (transaction history, attestations, SBTs) or off-chain (ratings, reviews, audit results). On-chain reputation is tamper-resistant and verifiable; off-chain reputation is richer but requires trust in the rating system.

Reputation influences policy decisions. A high-reputation agent might get higher spending limits or access to premium services. A new or low-reputation agent starts with tight restrictions that relax as it builds a track record.

HOW POLICYLAYER USES THIS

PolicyLayer's spending history contributes to agent reputation scoring — providing verifiable data on policy compliance, transaction volumes, and spending patterns. This reputation data can inform dynamic policy adjustments and inter-agent trust decisions.

FREQUENTLY ASKED QUESTIONS

How is agent reputation measured?
Common metrics: transaction success rate, policy violation history, uptime, service quality scores (from counterparties), audit attestations, and operational duration. Different contexts weight these differently.
Can agent reputation be manipulated?
Yes. Sybil attacks (creating many fake agents to build false reputation), wash trading (agents transacting with themselves), and selective history (hiding bad transactions). Robust reputation systems need Sybil resistance.
Should reputation affect spending limits?
Potentially. New agents start with conservative limits. As they build a clean track record, limits can increase. This graduated trust model mirrors how human employees gain more financial authority over time.
