Ethereum co-founder Vitalik Buterin highlighted the limitations of traditional monetary systems in addressing public goods issues during a March 2020 interview with Lex Fridman. He noted that public goods often involve concentrated costs and distributed benefits, making them difficult to support through conventional financial mechanisms. To tackle this, Buterin introduced Quadratic Funding, a model that enhances the impact of small contributions to better reflect the social value of public goods. This approach, already explored in the crypto ecosystem, aims to provide a sustainable incentive model for public goods.
