How It Works:

Every voter is given a budget of credits or tokens. 

They can cast multiple votes on any option or issue. 

But the cost of each additional vote increases quadratically. 

Formula:

If you cast n votes for an option, it costs you n² credits.



✅ Benefits:

Captures preference intensity – People who care more can spend more to show it. 

Reduces tyranny of the majority – Prevents majority voters from drowning out passionate minorities. 

Balances influence – Richer or more powerful voices don’t dominate as easily if everyone has the same credits. 



🧠 Used In:

Blockchain governance (e.g., Gitcoin Grants) 
Corporate governance experiments 
Political decision-making simulations
