Gitcoin Quadratic Funding · interactive mechanism simulation

Many small donations get amplified by a shared matching pool: match ∝ (Σ√c)² − Σc. Breadth of support beats depth — until Sybil clusters try to game it, and Passport + COCM discounting pushes back.

Illustrative simulation. Match is computed each round as (Σ√c)² − Σc, capital-constrained to the matching pool, mirroring Gitcoin's capital-constrained Liberal Radicalism (CLR) formula and Allo Protocol's on-chain settlement. Sybil-cluster donations still land as direct funds but have their match credit discounted by the Passport + COCM slider, echoing Gitcoin's real anti-fraud stack. Donation timing, sizes, and round length are randomized for visualization — not live onchain data. Part of The Onchain Experiment Atlas.
