POD256 | Bitcoin Mining, Freedom Tech, and Awesome Tangents

In this episode, Tyler and eco hold down the fort while Skot is away and dive deep into the frontier of Bitcoin-powered heating and open-source mining. They walk through a new Home Assistant + Venstar-based dashboard built for a customer that tracks miner-delivered BTUs vs. natural gas, stage changes, outdoor temps, sats earned, and economics—proving a single 5kW miner can carry a 3,000+ sq ft home through shoulder season. We unpack heat pumps versus combustion heat, why furnaces are oversized, the sovereignty trade-offs of remote monitoring, and the promise of “buddy systems” that pair hashrate heat with legacy boilers or even wood-fired hydronic setups. We also discuss policy shifts in Denver County, energy resilience at altitude and in extreme cold, and the real-world business models for small-town installers versus metro markets. Then we shift to the 256 Foundation’s roadmap. They outline funding realities post-Telehash and the near-term plan to keep four core open-source projects moving: Ember One hash boards (next rev targeting Intel BZM2), LibreBoard control board (v3 on deck and designed to orchestrate multiple boards, relays, and sensors), HydraPool (one-click, self-hostable pool with gamified dashboard and future Lightning/eCash payouts, Start9/Umbral packaging, and plugin architecture), and Mujina firmware (a Linux-like, no-dev-fee, open standard that can be flashed onto legacy S19-class hardware and, ultimately, ship on flagship miners). We talk market dynamics, why open source beats closed aftermarket firmware in the long run, and how Ember One serves as a reference platform for builders even if efficiency lags cutting-edge ASICs today. We wrap with community updates, forum plans for better knowledge sharing, shoutouts to our HydraPool supporters, and details on our “Open Sourcing the Bitcoin Mining Ecosystem” panel in Las Vegas on Monday, April 27.

In this live episode from Denver, we rally behind the Samourai Wallet developers, Keonne Rodriguez and William Hill, who are serving federal prison sentences for building noncustodial privacy software. We preview our evening event and planned livestream with Lauren Rodriguez—who then drops in mid-show to share first-hand updates on the case, including SDNY’s aggressive jurisdiction tactics, the judge swap that curtailed their defense, and why Treasury guidance and DOJ memos haven’t protected developers from novel prosecutorial theories. We discuss the broader stakes for Bitcoin, open-source development, Lightning compliance, and how these precedents could chill freedom tech far beyond privacy wallets. We close with concrete ways to help—signing the pardon petition, writing letters to Keonne, spreading awareness—and dive into updates on open-source mining: Mujina community momentum, GrapheneOS shifts, and new Antminer control board hacks enabling USB Wi‑Fi and custom firmware, all powered by rapid AI-enabled development. How to support: Sign the change.org/billandkeonne petition for Bill and Keonne, write letters to Keonne, amplify the case on social channels, and catch the fireside chat replay if you missed the livestream.

In this episode, we go deep on open-source Bitcoin mining firmware and tooling with Tyler, Skot, and eco. Skot shares his hack of running Mujina on stock Bitmain Antminer S19 control boards—no SD card, just Ethernet/USB flashing via LuxOS—unlocking full control of fans, single-board operation, and APW12 PSU management (with a cautionary tale about overheating and tripping a breaker). We discuss writing drivers for temps, fans, and the undocumented APW12 interface, 120V APW12 hardware mods (hat tip to Zach Bomsta and PivotalPlebTech), and why open firmware without dev fees beats closed alternatives. We also cover contribution best practices to Mujina, new CI pipelines, and how AI is accelerating clean, reviewable PRs. From immersion tweaks without fan spoofers to predictive maintenance and service models, we explore how open hardware/firmware/software can shrink repair times, improve reliability, and replace SaaS-style dev fees with real support. We zoom out to industry dynamics: opaque OEM support, warranty pain, and MOQs that stifle innovation—contrasted with community-built tools like HashScope (a Stratum MITM proxy for miner–pool debugging) and HydraPool experiments. We brainstorm miner incentives for 256F’s pool (e.g., shared block rewards or firmware-level hash-splitting), touch on eHash experiments, and celebrate grassroots devices like the Bitaxe Turbo Touch. The takeaway: open-source stacks like Mujina, HydraPool, LibreBoard, and EmberOne are the path to resilience—from home heaters to megawatt farms—and they need community participation now. Support the 256 Foundation, try the tools, file issues/PRs, and help build the mining future together.

In this episode, we debrief the second annual Heatpunk Summit from the legendary Hashtub in Denver. We recap how builders from HVAC, hydronics, and home mining came together to advance hashrate heating—complete with live hardware demos, workshops, and a brutally constructive critique of our boiler setup from a pro hydronics engineer. We dig into galvanic corrosion gotchas, smarter system design, and why practical, hands-on education is the real unlock for bringing Bitcoin miners back into homes and businesses as useful heaters.We also break down the big development with Canaan’s openness to support the home-mining and heat reuse market, what a “willing partner” ASIC manufacturer could mean for decentralization, and how small improvements—docs, APIs, and integrations—can catalyze a whole ecosystem. From workshop highlights (Home Assistant control, hydronics integration, open-source mining OS, and regulatory/insurance insights) to the industry’s AI pivots and the investability of open source, this is a high-signal builder’s recap with clear next steps and renewed momentum for hashrate heating.

In episode 105, we finally get the stream dialed and dive straight into hands‑on Bitcoin mining and open-source hardware updates. We share the latest on Ember One: a sneaky IO voltage domain bug uncovered by Mujina dev Ryan led to a desk‑side hardware fix that’s now pushing ~2 TH/s (target is 3.6 TH/s across 12 chips with proper cooling). We unpack chip and hashboard design lore—from stacked voltage domains and reliability in long chains to the insider politics at big silicon shops like Intel. We talk why selling chips openly matters, how spec sheets unlock real builder momentum, and why third‑party system builders (think Epic Blockchain) can grease the skids between chipmakers and end products.We cover Mujina’s trajectory toward a universal, Linux‑first, open firmware for miners—auto‑detect dreams vs config realities—and near‑term support for Ember One’s Intel boards and existing Antminers. We riff on home‑miner UX, remote monitoring, and agent/LLM tooling (cron‑job‑with‑superpowers, heartbeats, MCP integrations) to tune, alert, and manage miners. There’s buzz around FutureBit’s Apollo 3 (likely Auradine chips), open vs lawyered licenses, and the path from FPGA teaching rigs to community‑designed ASICs. We celebrate community hashing on the 256F HydroPool hash‑dash, solo‑block wins, and Heat Punk Summit prep (immersion hot tub included). Plus, a call to action: support developer freedom at change.org/billandkeonne. It’s a dense, builder‑first session on chips, firmware, agents, and bringing practical hashrate‑heat products to life.

In this live episode of POD256 (Ep. 104), eco is joined by Scott and Tyler—freshly minted 256 Foundation board members—for a fast-paced tour through open-source Bitcoin mining, DIY heat reuse, and the growing role of AI in hardware and firmware. We showcase D++’s new livestream overlay and the public monitoring dashboard at dash.256f.org/monitor.html, experiment with zap-based chat, and talk through the recent major difficulty drop and what it means for home miners. We revisit the 2021 China mining ban, S9 nostalgia, power and noise hacks, and the rise of an open mining stack—LibreBoard, HydraPool, and Mujina—aimed at dismantling proprietary control. From hot-tub immersion builds to sous vide steak with miner heat, we explore practical heat reuse, the need for reusable open components, and how AI agents can automate dashboards, tuning, and reverse-engineering—while warning about SaaS surveillance, Ring cameras, in-car spyware, and AI skill-store malware. If you want to support or learn, point hash to the 256 Foundation when we’re live, or spin up your own pool with HydraPool. Privacy, sovereignty, and open hardware are the path forward—bring your hash and your curiosity.

In this episode, eco & Tyler Stevens, CEO and founder of Exergy Heat, to dig into why open-source hardware and firmware are critical for the future of Bitcoin mining, especially for heat reuse in homes and businesses. We had a surprise visit from Skot and Joe Nakamoto dialing in from El Salvador, providing us with updates from the Plan B conference. We talk candidly about the constraints of closed, proprietary miners, shifting hardware trends (hydro-only, three‑phase, fewer 240V options), and how that undermines innovation, safety certification, and reliable product planning. We highlight the emerging open-source mining stack from the 256 Foundation, Mujina (firmware), open hash boards, control boards, and Hydra Pool, plus thriving communities (OSMU Discord, Hashrate Heatpunks, Jua Kali) that are lowering the barrier to actually build hardware with pick-and-place machines. We also cover real-world reference designs like a fully integrated sous vide heater driven by Miner power management and sensor feedback, the Heatpunk Summit bridging HVAC pros and mining devs, and Tether’s open-sourced MOS fleet platform. We close with mining-for-heat deployments (from buildings to towns), new pool dashboards, and how anyone can support decentralization by pointing hashrate to our donation-only Hydra Pool instance for the 256 Foundation. 

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 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 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.

In this episode, we dive into Canaan’s surprising GitHub drop and what it could mean for open-source mining, license tangles and all. We unpack the inclusion of CGMiner, the BSD-3 vs GPLv3 conflict, and Canaan’s RISC-V K230 SDK. We also explore the Nano 3/Nano 3S design, home-mining momentum, and the practical realities of certification (FCC/UL/CE/RoHS) for miners and heater-integrations. From local vs remote control to insurance implications, we discuss the gauntlet that open hardware must run and why decentralization requires openness. We spotlight Intel BZM2 progress: Bitaxe Bonanza’s lessons, the new BIRDS dev board, nine-bit serial hurdles, and a call for builders to leverage upcoming chip availability. Hydra Pool hits a milestone with public Dockerized releases and coinbase payout flexibility, while we test live at test.hydropool.org (and note Bitmain firmware limits). We cover Pluto’s HRF grant for fleet management, ESPminer stewardship funding, and D++’s Lightning-powered gamification for community builds. We also discuss Support for the Samourai Wallet devs, including context around sentencing and broader implications for open-source freedom. We preview Bitcoin++ Durham on Nov 15, share updates on the Samurai Wallet developers’ impending sentencing, and talk product integrity, copying, and the push to re-shore manufacturing. Finally, we tee up HeatPunk Summit 2026; bringing HVAC pros and open-source miners together, and have fun with Lightning “thermo-zaps” for live heating control.

In this episode, we range from ice-cold mornings and sunny Colorado skies to a deep dive on home mining, heat reuse, open hardware, and sovereign home automation. We recap getting featured in Forbes on Heat Punk projects and how mainstream coverage is finally grokking mining-as-heat, Canon’s heating-first designs, and Bitmain’s market dominance risks. We share real-world progress: integrating Canaan home miners with Home Assistant via APIs and Node-RED, using Zigbee sensors for room-aware thermostatic control, solar and TOU-aware automations, and the vision for a sovereign “miner control hub” box built on Raspberry Pi 5. We get nerdy on RISC‑V vs ARM, open firmware, and the Libre Board + Mujina roadmap, with detours through customs-destroyed SMD parts, packaging HydroPool for Docker, and the power of public, self-hosted pools after a solo-Block win with a NerdQAX. We also cover privacy and the surveillance creep: doorbells, cars, app signing, and why self-hosted tools (Pi-hole, PFsense, Mullvad, Signal, Proton/Tutanota) matter. We discuss HPC pivots by large miners, grid vs. heat-reuse economics, Canaan’s momentum in home heating, and the imminent Telehash on HydroPool with StartOS packaging on deck. Plus, the Stealth Miner enclosure, Bitaxe-powered heat projects, and shoutouts to the open-source crew making sovereignty practical at home, one sensor, miner, and Docker container at a time.

In this episode, we go deep on two fronts: protecting open-source projects from trademark hijacking and advancing real-world hash rate heating. We share the ongoing battle to oppose fraudulent USPTO filings on the BitAxe mark, why “TM” vs. registered matters, and how we’re navigating opposition, Madrid Protocol options, and the broader goal of keeping open hardware open without enabling scammers. We then switch to practical engineering: Tyler walks us through immersion mining powering radiant floor heat, dynamic performance scaling, control loops with Home Assistant, thermostats and dry coolers, and why tight software control beats expensive hardware band-aids. We unpack LibreBoard and Mujina plans, APIs, Stratum v1/v2 quirks, Intel vs. Bitmain chip behaviors, and how PyASIC/ASIC-RS standardize miner control. We also touch on FreeCAD pains, open-source CAD needs, educational content plans, and a wild idea: launching a BitAxe to low Earth orbit for space-mining experiments. The throughline: building a sustainable, open-source mining ecosystem where entrepreneurs can profit while dismantling proprietary roadblocks, especially for heat reuse at home and in buildings.Resources we discussed or referenced include: USPTO trademark process and oppositions, Madrid Protocol for international marks, Home Assistant integrations with open thermostats/APIs, LibreBoard and Mujina firmware architecture, BrainsOS and DPS/ATM concepts, PyASIC and ASIC-RS (standardizing miner APIs), FreeCAD/KiCad vs. proprietary CAD, and Dyson Labs’ BitAxe-in-space concept. We wrap with shout-outs to community hashers supporting 256 Foundation and an invitation to contribute, test, and build on these open platforms.

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.
