If You Use Bitcoin, Consider Supporting These Critical Open-Source Projects

The ethos of Bitcoin is enabled by a range of critical open-source software projects. Consider supporting this list of 30 such projects.

Our greatest asset as Bitcoiners is the blossoming open-source community that makes this movement possible. Open-source software empowers individuals around the world while remaining independent of governments and large corporations that continuously attempt to track, censor and control us. Many of these projects are not run for profit and do not have large budgets supporting them. Instead, they rely on an ever-increasing network of individuals worldwide who contribute time and energy to build them out, often without compensation.

So, how can those of us who support Bitcoin help support the imperative work of these projects? With Bitcoin 2022, for instance, our goal has been to throw the largest Bitcoin-focused event in history that is both accessible and welcoming to newcomers, while remaining true to the Bitcoin and open-source ethoses (disclaimer: Bitcoin 2022 is operated by BTC Inc, which also operates Bitcoin Magazine).

With this mission in mind, it has been clear that we must support open-source contributors and projects however we can. For us, this effort started with a dedicated conference hall at our event focused solely on open-source projects and the importance of free and open-source software (FOSS). In October, we launched our free open-source ticket program, providing $1 million worth of conference passes to open-source contributors of select projects. We have since added 24 additional projects now eligible for the free open-source tickets program.

The 30 highlighted projects below are, in our view, among the most critical for the advancement of Bitcoin. Readers should consider supporting these projects in their own ways, and those who have made a commit to their open-source codebase prior to October 1, 2021 can verify those commits and apply for a free, four-day pass to Bitcoin 2022 here.
