Bitcoin mining will be open-source, or Bitcoin remains permissioned.

Ember One
Open hashboard reference design
Libre Board
Open control board reference design
Mujina
Open mining firmware, the Linux OS of Bitcoin mining
Hydrapool
One-click open-source mining pool
Together, the four form the Development Kit.

In 2026, miners around the world pointed hashrate at our pool and found Bitcoin block 881423. Nine months later, our four projects ran together as a complete open-source mining kit. Real work, in public.
We fund the builders.
Grants for open-source Bitcoin mining work. Money from anyone, influence from no one.
A community, in code and out of it.
The forum is where the work gets argued out. The group chat is where it starts. Builders, miners, and advocates, worldwide.
