Contribution Multiplier

Contribution Multiplier (CM)

The Contribution Multiplier boosts a user’s voting power based on their contributions (donations or volunteering). It replaces the old “Impact Score” in voting calculations, offering better Sybil resistance and fairness while staying simple and familiar.

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(100,001)

• 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

Example Values

Impact Points	Contribution ($)	CM (Approx.)
0	$0	1
10	$100	33
100	$1,000	60
1,000	$10,000	80
10,000	$100,000	95
100,000	$1,000,000	100

🗳️ 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.

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.
