Quadratic Funding

Protocolo Monetário Descentralizado

A mechanism design protocol for allocating matching funds to public goods, in which the matching amount allocated to each project is proportional to the square of the sum of the square roots of individual contributions. The formula mathematically rewards breadth of support over depth, limiting funder dominance. Prototype: Gitcoin Grants.

Protocolo Monetário Descentralizado Atributos

Origens Mechanism design economics; public goods funding theory; quadratic voting research.
Formatos de Dados Contribution records (donor address, amount, project); matching pool parameters; sybil-resistance metadata.
Termos Permissionless project submission and donation; rounds operated by sponsors.
Fundos Gitcoin has distributed over $50M in matching funds across rounds (cumulative through 2024).
Baseado Em Buterin, Hitzig, and Weyl's Liberal Radicalism paper; quadratic voting theory.
Permissões Permissionless contribution; sybil-resistance via verification mechanisms (Gitcoin Passport).
Contrato Inteligente Yes — Gitcoin implementations use smart contracts for matching pool management and distribution.
Ferramentas de Desenvolvimento Gitcoin Grants Stack; Allo Protocol; supporting Gitcoin Passport for sybil resistance.
Maturidade / Padronização do Protocolo De Facto Standard for matching-fund public goods finance.
Estrutura de Confiança Algorithmic enforcement of QF formula; sybil-resistance through identity verification; community oversight of round administration.
Domínio de Aplicação-Alvo Public goods funding, open source software finance, civic technology grants, community resource allocation.
Posição de Aceitação do Jogo Modify-Additive — operates at public goods allocation layer alongside conventional funding.
Regime de Acumulação Capped via mechanism design — funder dominance limited algorithmically; recipient accumulation per project results.
Mecanismo de Coordenação Algorithmic mechanism design in service of deliberative aim — protocol weights breadth of support.
Modelo de Emissão Sponsor-allocated — matching pool funded by sponsors; allocation determined by QF formula across contributions.
Tipo de Sinal de Valor Single matching-fund unit; algorithmic weighting transforms contribution signal.
Padrão de Federação Cross-network bridge — protocol composable across rounds and ecosystems via Allo Protocol.
Independência de Substrato Substrate-neutral specification; production implementations blockchain-native.
