In episode 102, we are joined by Ryan, lead developer of the Mujina firmware, for a debrief on Telehash #3 live demo and the momentum around the 256 Foundation’s fully open Bitcoin mining stack. We walk through the sous vide miner demo that cooked ribeyes while mining on three Ember One hashboards with custom water blocks, controlled by our Libre board prototype running Mujina and pointed at Hydra Pool; an eight-hour, live-streamed showcase of the entire open stack working together. We reflect on why releasing everything on GitHub from day one matters, how modularity in Mujina accelerates chip and board innovation, and why open tooling lowers the barrier for builders from hobbyists to mega-miners. We dig into industry reactions from NEMS, interest from ASIC manufacturers, and the business case for open firmware at fleet scale. We discuss roadmap polish for Mujina (APIs, multipool support, power targets), Hydra Pool enhancements, HashScope share verification, and how open primitives enable better miner management, heating applications, and novel products. We shout out community contributors and hash renters who powered Telehash, preview Heat Punk Summit workshops (including Canaan’s home-mining session), and make the call for companies to support 256 Foundation grants that are already delivering outsized ROI for the entire mining ecosystem.
