Contribution Multiplier

Contribution Multiplier (CM)

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

Why We Use It

• Prevents abuse from fake or inactive accounts.

• Rewards meaningful contributions without letting whales dominate.

• Encourages newcomers to participate and grow their impact over time.

How It Works

Formula

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

• Impact Points = $10 donated or equivalent volunteering = 1 point

• The CM ranges from 1 (base) to 100 (max)

• Logarithmic growth means early contributions matter more

🗳️ Voting Power Calculation

With donation:

Voting Power = √(donated amount) × CM

Without donation:

Voting Power = 0.25 × CM

This discourages fake accounts from voting without contribution but still allows participation.

Verified accounts benefit from the Contribution Multiplier (CM). For unverified accounts, a factor of 0.1 is used instead of CM. This measure helps prevent the creation of multiple accounts to manipulate voting results.

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 = 1 point)
Fits with Clustering (COCM)	Designed to work well with variance-based cluster penalties

Optional Anti-Abuse Features

By using the Contribution Multiplier, we ensure fair, transparent, and Sybil-resistant voting—rewarding real contributors without excluding new or small participants.
