Contribution Multiplier

The Contribution Multiplier (CM) enhances a user's voting power by considering their previous contributions to social and environmental impact through donations, volunteering, or paid work.

  • Prevents abuse from fake or inactive accounts
  • Rewards meaningful contributions without letting whales dominate
  • Encourages newcomers to participate and grow their impact over time

Verified accounts benefit from the Contribution Multiplier (CM). For unverified accounts, a factor of 0.1 is used instead of CM. This helps prevent multiple-account manipulation.

How It Works

Impact Points: $10 donated = 10 points. The CM ranges from 1 (base) to 100 (max). Logarithmic growth means early contributions matter more.

Formula

If Impact Points < 5:
    Contribution Multiplier = 1
Else:
    Contribution Multiplier = 1 + 99 × log(Impact Points + 1) / log(1,000,001)

Voting Power Calculation

Voting Power = sqrt(donated amount) × CM

For votes without donation:

Voting Power = 0.25 × CM

Why It's Better

Benefit How
Sybil Resistance Starts at 1.0, giving very low power to new/unused accounts
Fair for Top Contributors Caps at 100, avoiding whale domination
Welcoming to Newcomers Grows quickly for early contributions
Simple & Transparent Easy to explain, based on real-world values ($10 = 10 points)
Fits with Clustering (COCM) Designed to work well with variance-based cluster penalties
