Definition ∞ In digital economics, a Public Good refers to a non-excludable and non-rivalrous service or resource that benefits the entire community, regardless of individual contribution. Examples in the blockchain space include open-source protocol development, foundational research, and shared infrastructure. Funding and maintaining these goods often pose a challenge due to the free-rider problem.
Context ∞ The funding and sustainability of public goods within the cryptocurrency ecosystem are a recurring topic in news and community discussions, particularly concerning decentralized autonomous organizations and grant programs. Debates center on effective mechanisms to incentivize contributions to shared infrastructure and research that benefits all users without direct profit motives. Innovative funding models, such as retroactive public goods funding and quadratic funding, are actively explored to address this challenge.
