POD256 | Bitcoin Mining, Freedom Tech, and Awesome Tangents

In this episode, we sat down with Skot and Ryan to unpack Ryan’s trip to BTC++ Nairobi, where he represented the 256 Foundation and shared our open-source mining mission with builders from across Africa. Ryan talked about the incredible energy of the local Bitcoin community, the real-world use of Lightning and mobile payments across borders, and why Africa offers such a powerful glimpse into Bitcoin’s practical value. We also dug into the strong interest in open-source mining, from Ryan’s main-stage talk on the 256 Foundation’s mining stack to the many conversations he had with developers excited to contribute, experiment, and build without the barriers of closed hardware and firmware.We also went deep on Ryan’s hands-on mining workshop, where attendees learned Bitcoin mining from first principles, CPU-mined on a classroom Signet, assembled Bitaxes, and watched the network shift as ASICs came online. From there, we explored what Ryan saw at Gridless’s biomass-powered mining site in Kenya, the technical realities of balancing power generation with mining load, and promising local projects like BitShaka and Juakali. Throughout the conversation, one theme kept coming up: open-source mining is becoming a practical path for education, experimentation, decentralization, and entirely new energy use cases—and the momentum behind Mugena and the broader 256 Foundation mission is clearly growing.

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.

In our 100th episode, we celebrate three years of POD256 and almost two years of building the open-source Bitcoin mining stack. We share behind‑the‑scenes stories from our first Telehash block find and chart what’s coming for 2026. We walk through how the 256 Foundation allocated over $400k in grants across Ember One (open hashboard design), Libre Board (open control board), Mujina (open miner firmware), and Hydra Pool (self‑hosted pool), and how these projects are already flipping the closed “black box” mining model on its head. We dive into progress updates: Mujina running on Bitaxe Gamma, early Ember One integrations and cooling, Hydra Pool one‑command spin‑ups, plus community contributions like Stratum v2 support and Home Assistant control; and preview our plan to run Telehash #3 on a fully open stack live. We also invite miners and devs to point hashrate, contribute code, and join us at Telehash and NEMS as we turn this momentum into a product-style demo of open mining in action.We revisit the wild Telehash night when an Apollo-powered solo pool briefly wrangled an exahash and struck block 881423 (shout-out to Megawatt!), reflect on building the 256 Foundation and this pod from the early “Hash Cast” days, and outline how anyone from heatpunks to large farms can plug into the stack. Finally, we highlight community calls to action: spin up Hydra Pool, hack on Mujina, help us evangelize at meetups and campuses, and support free and open-source mining. Last but certainly not least: Code is not crime, support the Samourai devs’ families and sign the pardon petition here: https://billandkeonne.org

In this episode, eco & Tyler welcome back Skot who was at the African Bitcoin Conference, this year hosted in Mauritius, where he spoke on open-source Bitcoin mining. We swap travel tales (including Scott’s chaotic Paris layover) and impressions of Mauritius, the conference venue, and side events focused on Bitcoin education. We dig into mining headlines: Bitdeer’s missed ASIC roadmap and investor lawsuit, Bitmain’s history (Antbleed) and why open-source mining matters, and MicroBT’s M70-series lineup pushing industrial-scale, three-phase miners. Skot explains the theory behind Bitdeer’s hyped “adiabatic charge recovery logic,” why it’s hard to scale, and how thermal and power density realities define miner design. We go deep on open hardware and firmware progress: Braiins’ open control board, Secure Boot obstacles, and Mujina’s modular path to safe, customizable, dev-fee-free mining; plus Skot’s BitCrain control board concept for USB‑controlled fleets. We share shop-floor lessons building AddIt boards and Ember One prototypes (solder paste, tombstoning, reflow profiles) and celebrate practical innovation like Gridless’s open-source JuaKali direct-DC solar mining kit. On home-mining UX, Tyler demos new Home Assistant integrations for Canaan Avalons and WhatsMiner, and we preview Hydra Pool deployments (Grafana/Prometheus dashboards) for the upcoming Telehash. Finally, we update the community on the Samourai Wallet case: Keonne’s facility designation, the continuing push for a presidential pardon, and how to support via petition and donations. #PardonSamourai.

In this urgent and heartfelt conversation, we sit down with Keonne Rodriguez, cofounder of Samourai Wallet, to unpack his prosecution and five-year federal sentence for building noncustodial Bitcoin privacy software. From the government’s shifting theory of “unlicensed money transmission” to conspiracy charges built on out-of-context tweets and slides, Keonne details how a noncustodial wallet was framed as a financial institution, even after FinCEN itself reportedly said it was not. We dig into Whirlpool’s design (no custody, blinded coordination), the difference between mixers and CoinJoin, and how broad prosecutorial language threatens developers, node operators, and even miners. Keonne walks us through the pretrial gauntlet, denied motions, the plea calculus that cut risk from 25 years to 5, and why truth often can’t reach a jury. He shares practical digital hygiene tips, why open source kept Samourai’s work alive (Ashigaru, RoninDojo), and how the community can help by amplifying the petition and supporting families. This episode is a call for builders and Bitcoiners to rally, defend open-source freedom tech, and stand against precedent that endangers everyone who values privacy. Resources and how to help: Sign and share the petition for clemency and support families at billandkeonne.org. If donating, use the non-crypto options listed until the dev's surrender date to avoid any bail-condition issues. Keep learning about CoinJoin, Dojo, and community forks like Ashigaru and advocate for legal defense infrastructure to protect open-source builders going forward.

In episode 94 of POD256, we cover a full slate of Bitcoin mining and freedom tech updates from Nashville to Denver. We recap the Bitcoin Veterans telehash fundraiser that briefly peaked near 98.5 PH, discuss PPLNS dynamics at Ocean and Slush/Brains, and explore Square’s new Lightning payments rollout. We share a field report from installing an immersion-based hashrate heating system on subsidized power in Buena Vista, the pros/cons of immersion (including an oil-leak mishap), and how recapturing heat favors small, distributed miners. We dive deep into 256 Foundation progress: Ember One hashboard prototyping on the pick-and-place, the Libre control board, Ant Hat and Edit boards, Hydra Pool’s PPLNS design with a public shares API, and the imminent open-sourcing of Mujina firmware. We also preview January’s Telehash at Bitcoin Park where we’ll “eat our own dog food” by running Ember One + Libre + Mujina against our self-hosted Hydra Pool instance. Finally, we break down the Samourai Wallet sentencing, why the “unlicensed money transmitter” framing is dangerous despite Samourai’s non-custodial design, the realities around “restricted markets,” and why broad community action (including a pardon push and better anonymity for devs) is critical. Plus: Start9 VPN tunneling in Alpha 12, packaging Hydra Pool for StartOS, and listener hash-rate shoutouts across Lincoin, Solo CK, Public Pool, and Ocean.
