Proof of Bags - On-chain behavioral reputation layer for Bags-launched tokens

Overview

PoB (Proof of Bags) provides transparent, explainable reputation scores for tokens launched via the Bags platform. The system uses real Solana on-chain activity data to differentiate builders from extractors without censorship.

Key Features

  • Transparent 0-100 reputation scoring
  • Behavioral badges: Fresh, Growing, Extractive, Trusted
  • Real on-chain data from Solana blockchain
  • No black box algorithms - every score is explainable
  • Enhanced by Ethos Network when available

Scoring Components

Ethos Reputation (0-30 points)

Creator credibility score from Ethos Network, normalized to 0-30 points. When unavailable, points are redistributed proportionally.

Creator History (0-20 points)

Based on number of previous launches, average token lifespan, and early extraction patterns.

Activity Consistency (0-20 points)

Measures on-chain transaction patterns using tiered thresholds and activity recency. Derived from real blockchain data, not market prices.

Supply Concentration (0-15 points)

Evaluates token supply distribution among holders using on-chain data. Based on actual token holdings, not trading activity.

Fee Behavior (0-15 points)

Analyzes frequency and timing of fee claims relative to fees accrued.
