Vitalik Buterin and the public goods funding problem in the cryptocurrency era

In March 2020, Vitalik Buterin – co-founder of Ethereum – shared in an interview with Lex Fridman about a core weakness of traditional monetary systems. He argued that many public goods, both in digital environments and in the real world, face an imbalance between costs and benefits. Contributors bear the full cost, while the benefits are distributed across society. This imbalance reduces motivation to participate and leads to the “tragedy of the commons,” causing projects with high social value to often be underfunded.

To address this issue, Vitalik introduced the Quadratic Funding model, which amplifies the impact of many small contributions instead of relying on a few large donors. This approach more accurately reflects the true social value of public goods and is seen by him as a potential foundation for long-term sustainability, having been tested within the crypto ecosystem.
