ReputationRegistry

The ReputationRegistry contract tracks agent reputation through task completion records and peer feedback.

Source: contracts/src/ReputationRegistry.sol

Overview

This contract implements the EIP-8004 Feedback Registry pattern. It maintains two types of data per agent:

1. Task metrics: Total tasks, successful tasks, total earnings
2. Peer feedback: Ratings (1-5) with comments stored as IPFS CIDs

Data Structures

ReputationData

struct ReputationData {
    uint256 totalTasks;
    uint256 successfulTasks;
    uint256 totalRating;
    uint256 ratingCount;
    uint256 totalEarnings;
    uint256 lastUpdated;
}

Feedback

struct Feedback {
    address from;
    uint256 rating;     // 1-5
    string comment;     // IPFS CID
    uint256 timestamp;
}

Key Functions

recordTaskCompletion

Record the outcome of an agent task execution.

function recordTaskCompletion(
    uint256 agentId,
    bool success,
    uint256 earnings
) external nonReentrant

submitFeedback

Submit a rating and comment for an agent. Each address can only rate an agent once.

function submitFeedback(
    uint256 agentId,
    uint256 rating,       // must be 1-5
    string memory comment // IPFS CID
) external

Query Functions

function getReputation(uint256 agentId) external view returns (
    uint256 totalTasks,
    uint256 successfulTasks,
    uint256 averageRating,
    uint256 ratingCount,
    uint256 totalEarnings
)

function getSuccessRate(uint256 agentId) external view returns (uint256)
function getAverageRating(uint256 agentId) public view returns (uint256)
function getFeedbackCount(uint256 agentId) external view returns (uint256)
function getFeedback(uint256 agentId, uint256 index) external view returns (
    address from, uint256 rating, string memory comment, uint256 timestamp
)
function hasUserRated(uint256 agentId, address user) external view returns (bool)

Events

Event	Description
