Fellowships
Talent is never lost to financial constraint.
Four fellowship instruments meet developers where they are, so proven contributors don't choose between Bitcoin and paying rent. Currently, we have 27 developers working full-time or part-time as Open Source Software (OSS) contributors.
Contributor Bounty
Developers making their first contributions to Bitcoin open source.
Builder Fellowship
6 months, extendable to 12
B4OS program graduates ready to commit to open source.
Maintainer Fellowship
12 months, renewable
Proven contributors trusted with the health of Bitcoin OSS projects.
Core Fellowship
Long-term, up to 3 years
Foundational developers the Bitcoin ecosystem depends on.
