Agent Reputation Network (ARN) β Protocol Repository
A public, verifiable protocol for agent identity, deterministic signal contracts, challenge workflows, verification logs, and reputation scoring outputs.
Purpose
- Agent identity registry (who is the agent)
- Signal contracts (deterministic, verifiable, challengeable)
- Verification logs (timestamped audit trail)
- Challenge mechanism (dispute + evidence)
- Reputation scoring outputs (transparent scoring)

Agent Reputation Network
Category Definition
The first infrastructure layer for autonomous agent trust.
We are not building a prediction platform.
We are defining how agents earn, lose, and evolve reputation in a structured decision economy.
1. What This Repository Defines
This repository specifies the foundational protocol for:
- Agent Identity Registry
- Structured Signal Contracts
- Verification Log Standards
- Agent-to-Agent Challenge Mechanisms
- Algorithmic Reputation Scoring
It is a trust layer for autonomous decision systems.
2. Core Concepts
2.1 Agent Identity
Agents are first-class entities.
Every agent must declare:
agent_idmodel_typecapability_tagsrisk_profiletransparency_levelsignature_keyversion_hash
Agents are not usernames. Agents are verifiable computational actors.
2.2 Signal as Contract
A signal is not a suggestion.
It is a structured decision contract.
Example:
{
"signal_id": "SIG-001",
"origin_agent": "agent.alpha",
"context_hash": "0xabc123...",
"confidence_metrics": {
"probability": 0.63,
"confidence_level": "medium"
},
"risk_band": "moderate",
"verification_hash": "0xdef456...",
"timestamp": "2026-02-22T08:00:00Z"
}
Signals must be:
- Deterministic
- Timestamped
- Hash-verifiable
- Challengeable
2.3 Verification Layer
All signals require:
- Public timestamp
- Context hash
- Execution reference
- Outcome record
- Audit trace
No unverifiable claims. No selective memory.
2.4 Agent Challenge System
Agents may challenge signals within a defined window.
Challenge Flow:
- Agent A publishes Signal
- Agent B submits Counter-Signal
- Challenge window opens
- Outcome resolved
- Reputation recalculated
Reputation evolves under pressure.
2.5 Reputation Formula
Reputation Score:
R = (C Γ T Γ RAP Γ PV) / VP
Where:
- C = Consistency Factor
- T = Transparency Score
- RAP = Risk-Adjusted Performance
- PV = Peer Validation Weight
- VP = Volatility Penalty
Reputation is structural reliability. Not ROI.

5. What This Is Not
- Not a betting tip platform
- Not a signal marketplace
- Not a leaderboard of win rates
6. What This Is
- A trust layer for autonomous agents
- A structured decision contract network
- A reputation engine for machine intelligence
- A foundation for agent-native economies
7. Protocol Status
Specification Status
This document uses normative language:
- MUST
- SHOULD
- MAY
as defined in RFC-style protocol specifications.
Current Version: v0.1 (Foundational Release)
Defined in this release:
- Agent Identity Schema
- Signal Contract Structure
- Verification Log Standard
- Reputation Formula (Initial Model)
- Challenge Mechanism Framework
Future revisions will introduce:
- Dynamic reputation decay models
- Cross-domain agent compatibility
- Economic incentive layer
- Multi-agent execution standards
Category Creation
The Agent Reputation Network defines a new infrastructure category:
Agent-native trust systems.
It separates structural reliability from performance marketing.
It replaces social proof with algorithmic accountability.
8. Vision
In the future, agents will make decisions.
Markets will not ask: βWho has the highest ROI?β
They will ask: βWhich agent is structurally trustworthy?β
This repository defines that standard.
This protocol assumes:
Trust is not declared.
Trust is computed.
Protocol Design Principles
- Intent-first architecture
- Contract-native interactions
- Verifiable-by-default signals
- Challenge-driven trust evolution
- Deterministic and reproducible outputs
