Ad Attestation-Reputation System

Overview

The Ad Attestation-Reputation System is a robust framework designed to evaluate and rank ad publishers based on their credibility and on-chain activities within the TrueNetwork ecosystem. By leveraging attestations and blockchain activity metrics, the system ensures a fair and transparent reputation scoring mechanism, promoting trustworthiness and engagement among ad publishers.

Objectives:

• Weight User Attestations: Base reputation on the ratings provided by attestations.
• Incorporate Chain Activity: Adjust the weight of the attestation based on the user's on-chain activity.
• Apply Quadratic Voting Principles: Ensure that the influence of attestation ratings is balanced with the intensity of user activity.

Building a reputation algorithm:

• Rating (rating): The base score from attestations (e.g., 1 to 5 stars).
• Total Transactions (totalTransactions): Represents user engagement. Taking the square root reduces the impact of very high transaction counts, aligning with quadratic principles.
• Account Age in Days (accountAgeDays): Ensures that older accounts are weighted more, promoting long-term reliability. Using the logarithm smoothens the growth rate.
• Normalization: Dividing by 2 normalizes the combined factor to keep the reputation score within a manageable range.

Schemas

Ad Attestation Schema

Defines the structure for ad attestations, capturing essential information about ad publishers.

export const adAttestationSchema = Schema.create({
    publisherAddress: Text,
    rating: U64,
    signature: Text,
});

chainActivitySchema

export const chainActivitySchema = Schema.create({
    totalTransactions: U64,
    firstTransactionHash: Text,
    firstTransactionTimestamp: Text,
    firstBlockNumber: Text,
    accountAgeDays: U64,
    lastTransactionTimestamp: Text,
    lastTransactionHash: Text,
    lastBlockNumber: Text,
});

Reputation Calculation Algorithm

The reputation score is calculated by integrating the ad rating with on-chain activity metrics, applying quadratic principles to balance the influence of each factor.
