Brink is proud of our grantees' contributions to Bitcoin Core!
While Brink chooses specific grantees to fund, the source of our funds is *entirely* from the community.
So in reality, funding is even more decentralized than this chart indicates...
[1/2] Who funds Bitcoin Core?
Based on the number of developers with over 10 commits in the last 12 months,
@bitcoinbrink
is the top funder of Bitcoin Core. The data shows that the funding is now quite well diversified.

Bitcoin’s value rests on its security and stability. Everything we build on top of Bitcoin depends on the base protocol and reference implementation being rock solid. One critical bug in the protocol or implementation has the potential to crash the entire Bitcoin economy.

That stability of the base layer depends on skilled developers vetting new proposals, reviewing changes, and fixing bugs. Yet there are few developers who have the experience to make impactful contributions, and the path to become a Bitcoin developer is notoriously difficult.
