"Btrust
Btrust is a non-profit organization with a dedicated mission to decentralize the development of Bitcoin software. Our focus is on fostering developer talent in the global south and supporting the free and open-source Bitcoin ecosystem.

Founded in 2021 with a generous 500 BTC donation from Jack Dorsey and Jay-Z, we believe that decentralization of the people building for and on Bitcoin enhances its resilience, reach, and relevance as a global currency."
