Additional funding extends Mujina's 2026 term through December without a pause. The final stretch: S19j Pro and S19k Pro polish, flashable OS images, and the installer that boots a miner straight into open firmware.

After a funding pause, the Foundation reactivates Libre Board's 2026 term for four months, financing the final validation so that anyone can build the open reference design with confidence.

The open firmware takes on its 2026 roadmap in priority order: continued Ember One and Libre Board support, first support for an industrial miner, and the start of flashable OS images.

The open control board heads for revision three: revisions one and two fully tested, voltage regulation fixed, power validated across 12 to 24 volts, and the design readied for fabrication.

The open pool gets easier to run: payouts become a plugin interface, Umbrel and Start9 packages make a pool a one-click install, and Stratum v1.5 gets its specification.

The open operating system of a miner: fully open GPLv3 firmware, the Linux kernel of Bitcoin mining, built to run on any miner.

The open motherboard: an open control board reference design with every interface, an unlocked bootloader, and a copyleft hardware license.

The open pool: stand it up in one command, with payouts written into the coinbase so the operator never touches the money.

The 256 Foundation's first grant funds an open-source Bitcoin mining hashboard, built from the chip up and published for anyone to build.
