In this episode, the 256 Foundation crew and developer d++ go deep on HydraPool, our open‑source Bitcoin mining pool stack, and the new HashDash and upcoming TeleDash dashboards powering the Telehash fundraiser stream. We unpack how HydraPool fits into the broader plan to open‑source the entire mining stack (hashboard, control board, firmware, and pool), its Rust-based design inspired by CKPool and P2Pool v2, and flexible payout models (solo, PPLNS, and multi-address coinbase). We also talk user experience tweaks for Telehash, like smoothing hash rate visualization, displaying best shares, units for difficulty, leaderboard ideas, and integrating Nostr npubs for social profiles. D++ walks through the HashDash visualizer and plans for TeleDash: real-time overlays for stream viewers and a separate jumbotron view showing total hash rate, active workers, funds raised (on-chain and Lightning), block height, BTC price, donation messages, odds, leaderboards, and instructions to point hash rate. We discuss stress-testing the pool to 10,000 workers, Prometheus data, and potential features like miner-type fingerprinting via user agents. We also touch on industry rumors around Bitmain’s S23 air-cooled units, shifting manufacturer focus to hydro/data-center gear, hand‑me‑down hardware implications, and why open source is crucial as proprietary vendors change course. Finally, we preview Telehash (join at pool.256foundation.org:33303 with a valid BTC address), celebrate contributions to Samourai dev families, and tease hardware progress on Ember One, Mujina firmware, water-cooled blocks, Heat Punk Summit plans, and more; all with an open-source-first ethos to dismantle the closed mining monopoly.

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 today’s POD256, we opened with a timely update on the Change.org petition to pardon Samourai Wallet developers Bill and Keonne. We dug into confusing verification flows, the low conversion rate from views to valid signatures, why pseudonyms and disposable emails are allowed, and why donations on Change.org don’t reach the families; direct support should go to GiveSendGo. We also covered the growing media push, the reported acknowledgment from President Trump, and counter-narratives forming in the broader media. From there, we pivoted into mining: BitCrane and Addit boards for S19/Whatsminer control, Mujina support, 120V PSU unlocks, and heat-reuse projects. We previewed our Telehash fundraiser and HydraPool setup for NEMS, discussed pool trust and verification (including scam pools and coinbase-checking tools), OCEAN’s decentralization claims, and why share-chain style P2Pool v2 matters. We wrapped with open hardware manufacturing updates (pick-and-place triumphs and solder paste woes), Heatbit’s new radiant “Canvas” miner, and practical self-hosting lessons; closing with a call to action to sign the Samourai petition and keep the pressure on while the window remains open.

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 episode of POD256, Tyler and eco catch up on winter in Colorado, project trucks, and then dive deep into the latest in Bitcoin mining and freedom tech. We recap last week’s conversation with Keonne Rodriguez of Samourai Wallet, the urgent push for signatures on the pardon petition, and practical ways to support; while clarifying privacy-friendly ways to sign. We also discuss GrapheneOS stepping back from France amid regulatory pressure, the broader trend of governments targeting toolmakers, and why freedom tech from Bitcoin mining to open hardware matters now more than ever.On the mining front, we showcase Hydra Pool, our open-source non-custodial pool software, now running in our lab and soon to be public for Telehash #3 and beyond. We walk through the Grafana dashboard, PPLNS accounting for up to 100 addresses per coinbase, and our goal to migrate community hash over for solo mining support. We also update on Ember One and Libre Board: open-source hashboard and controller hardware moving through v5 prototyping on our pick-and-place, aiming for developer kits before fully assembled plug‑and‑play units. We hit Bitmain’s reported federal probe, solo block wins by small hashers, and the path to open hardware parity. We close with hasher shoutouts and a call to action: sign the Samourai petition and join Telehash to help fund open mining R&D.

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 this episode, we go deep on the shifting landscape of Bitcoin mining hardware, open-source firmware, and why trustless stacks matter for miners big and small. Fresh off the local Bitcoin++ in Durham, we recap the vibe: a developer-heavy crowd, real collaboration between devs and miners, and our announcement of the Mujina developer preview—an open-source mining firmware now publicly accessible for hands-on testing. We discuss practical demo plans for the HeatPunk Summit, creative power ideas (from inverter gens to EVs like the F-150 Lightning/Cybertruck), and what it takes to stage quiet, controlled mining demos. From secure boot cat-and-mouse games to aftermarket control boards, we unpack why closed firmware is antithetical to Bitcoin’s trust-minimized ethos, the history from CGMiner and GPL violations, and how LibriBoard, Hydro Pool, and Start9 packaging can radically reduce friction for at-home and pro operators. We also cover Stratum v2 progress, open-source community wins (Home Assistant integrations, config-first setups), and tangible on-ramps for developers—including free Auradine chips from 256 Foundation for reverse engineering and Bitaxe-based Mujina dev workflows. We close with a candid segment on Freedom Tech, the chilling effects of targeting software developers, and why building and supporting open-source tools is essential for a free society.

In this episode of POD256, we go deep on open-source Bitcoin mining with live updates from TabConf. We kick off with some tax-day banter and quickly shift into the real meat: the imminent release of Mujina; an open-source, Rust-based, modular mining firmware designed for flexibility (think hot-swappable hashboards, per-chip capability-aware work assignment, and embedded Linux distro ambitions). We discuss the Ember One hashboard iterations, pragmatic scope control, and why a community-driven, iterative approach matters. Then we dive into HydraPool, our open-source, one-click, low-friction Stratum v1 pool initiative: why we moved from a CKPool fork to a fresh Rust stratum server, PPLNS design trade offs, verifiable share accounting via API streams, and breaking legacy limitations like coinbase output caps imposed by vendor firmware. From the floor at TabConf, Skot and AverageGary join to showcase Stratum v2 progress packaged for Start9, NAT traversal via hole-punching (Iroh), and the vision that every meetup can host its own pool. We explore encrypted, binary Stratum v2; coinbase privacy; integrating Rust tooling (BDK/LDK/ASIC-RS); and practical features like dummy work for heat reuse and load management. We compare payout mechanics (Ocean, Datum/TIDES, DMND SliceJD with job-declared fees), custody nuances, and eCash/eHash concepts for flexible, local pool accounting. We wrap with real-world updates: home-assistant-driven solar-aware mining control, shout-outs to our hasher community, Telehash plans, and why smaller, faster nodes and decentralized pools will birth more economic nodes. It’s a dense, nerdy, forward-looking tour of the open mining stack becoming reality.

In this episode, I host a deep dive on open-source Bitcoin mining hardware and network policy. We kick off with updates on the Ember One v5 hashboard design: a modern, smarter voltage regulator with digital telemetry and over-temp safeguards, header breakouts for optional fan-control daughterboards, and the tradeoff of dropping 24V input in favor of better performance up to 17V. We talk real-world cooling scenarios from hardwired desk fans to immersion, water blocks, and the dream of a fully passive, fanless space-heater miner, and how firmware can target room temperature using external thermostats or Home Assistant, including hashing on dummy work for heat when the network’s down. We also cover system builds with S9 chassis reuse, USB hub scaling, and the open-source release on the 256 Foundation’s GitHub.Then we zoom out to software and network sovereignty: IPv6 support work on Bitaxe and why testing the full chain (ISP to router to device) matters; the merits of self-hosting vs cloud IoT, dynamic DNS, and why more economic nodes will matter as home mining grows. We wade into Bitcoin Core vs Knots relay/mempool policy drama, argue for keeping “the knobs” and user choice, and explore a BIP proposing a scriptable mempool policy. Finally, we unpack copyleft vs MIT licensing for hardware and software, what “preferred format for modification” means for open hardware (use real CAD source, e.g., KiCad), how legal enforcement has played out (Cisco/Linux precedent), and why open-source accelerates development, decentralizes control, and creates durable ecosystems using Bitaxe’s rapid growth as a case study.

In this episode, the crew reunites post-ImagineIF to debrief an energizing week across Bitcoin, AI, energy, and Freedom Tech. Rod thanks the team and presenters for delivering high-signal talks within tight constraints, and we reflect on why keeping events intimate translates into more action at the community level.
