Outline & Notes​

Round Rock Bitcoiners Meetup #30: Decentralized Mining Workshop

Community​

  • Mission: "Share bitcoin knowledge, tools, and resources while creating a peer to peer network"
  • Guidelines: Bitcoin only, Chatham House Rules
  • Initiatives: #HashTheTorch (1-month S-19 loaner), #RunWithHal (Satoshi Trail Run for ALS)

Mining Fundamentals & Evolution​

  • CPUs to GPUs to FPGAs to ASICs to Industrial Facilities
  • Workshop advocates return to Home Mining for network security and open-source innovation

Payout Schemas​

  • PPS: fixed payout per share, stable, no tx fees
  • PPLNS: based on recent shares when block found, more volatile
  • FPPS: includes transaction fees (Braiins, Foundry)
  • TIDES (Ocean.xyz): transparent, predictable

Solo Mining​

  • Mining alone for full block reward
  • 12 blocks solo mined in 2024

Hardware Comparison​

| Feature | BitAxe 401 Supra | Antminer S19j Pro+ | | Hash Rate | 733 GH/s | 120 TH/s | | Power Consumption | 15-18 Watts | 3,250-4,080 Watts | | Efficiency | 20-25 J/TH | 27-34 J/TH | | Monthly Cost | ~$1.26-$1.51 | ~$326.59-$411.84 |

Noise & Heat Solutions​

  • AC Infinity: Cloudline 8" Fan, Inline Duct Silencers
  • Fruition Designs: 3D-printed ASIC silencing/cooling kits
  • Njord Fan Control PCB: allows Bitmain miners to control AC Infinity fans automatically

Software & Protocols​

  • StratumV2: improves security/efficiency; miners control block templates (Dmnd.work, Braiins.com)
  • DATUM: custom templates directly on node; integrates with Ocean.xyz for pooled or solo mining
  • AxeOS: custom Bitaxe firmware to minimize latency
  • Bitcoin Knots: enhanced privacy/decentralization

Setup Guides​

BitAxe to Solo Pool​

  1. Power on, access IP on screen
  2. Settings > Network > WiFi
  3. Stratum URL: public-pool.io, Port: 21496

  • Default: pool mine on OCEAN, switch to Lottery if pool offline
  • Disable "Pooled Mining Only"

Lightning Payouts (Bolt 12)​

  • Use C-Lightning on StartOS
  • Enable Bolt 12 to generate offer
  • Import configuration into Ocean.xyz for automated Lightning payouts
