Mining with Rented Hashrate: Braiins Hashpower + DATUM

Pared-down outline for ~45 min: 20 min content + 25 min demos & Q&A.

Slide 1: Connect with Us​

Title: Round Rock Bitcoiners Body:

  • Telegram / Keet / SimpleX — links on the table
  • Stay on topic (bitcoin only), respect privacy (Chatham House Rules)
  • Next month: TBD — volunteer speakers & sponsors always welcome

Slide 2: Circular Economy​

Title: Circular Economy Body:

  • Local peer-to-peer exchange of goods, services, and sats
  • Supporting bitcoin-accepting businesses in Round Rock
  • Keeping value within the community

Slide 3: Title — Mining Like the Big Players​

Slide 4: Why We're Here Tonight​

  • You don't need a warehouse in West Texas to mine Bitcoin
  • New hash marketplaces let you rent PH/s-scale hashrate on-demand
  • Combine rented hash with DATUM and own your block templates
  • We'll show you the tools, then demo them live

Slide 5: The Centralization Problem​

  • 3–4 pools control >50% of Bitcoin's hash rate
  • Pool operators choose which transactions make it into blocks
  • Geographic centralization = regulatory capture risk
  • How do we participate at scale without feeding the machine?

Slide 6: Two Solutions — Rent Hash + Control Templates​

Rent Hash (no hardware)

  • Braiins Hashpower (beta): live order book, instant delivery
  • Minimum order: 10,000 sats (~$9)

Control Templates (your rules)

  • DATUM + Stratum V2: miner-controlled block templates from your own node
  • Pool only handles difficulty + reward coordination

Together: Industrial-scale hash, your transactions, your rules.

Slide 7: Braiins Hashpower — Overview​

  • Launched Jan 2026 (public beta)
  • On-demand SHA-256 hashrate
  • Live order book: bid/ask in BTC per EHs/day
  • Current market: ~3.15 EH/s total, ~45% utilized
  • 0% service fees during beta
  • Telegram: @braiinshashpower

Slide 8: How the Market Works​

Bids (You Buy):

  • Place bid at your price (e.g. ₿0.49 / EHs/day)
  • Delivers continuously while balance covers it
  • Cancel anytime; no contracts

Asks (Miners Sell):

  • Cheapest liquidity: ₿0.47–0.48 range
  • Real-time charting: 5M/15M/1H/4H/1D timeframes

Slide 9: Solo Mining & Hashrate Autopilot​

One-Click Solo (Lottery Mode)

  • Fixed cost, fixed duration, all-or-nothing
  • 10,000 sats → 1.95 PH/s for ~2 hours (0.0025% win chance)
  • Provably fair; full block reward if you hit

Hashrate Autopilot

  • Set rules: "Buy hashrate when price < X, route to my DATUM node"
  • Auto-rebalancing between pools based on payout models
  • Demo: http://<AUTOPILOT-HOST>:<PORT>/

Slide 10: Template Control — Two Paths​

Path A: DATUM + Ocean.xyz

  • Run your own node (Core or Knots) with DATUM
  • Build templates from your mempool
  • Route rented hashrate to your DATUM endpoint

Path B: Stratum V2 + dmnd.work

  • Open protocol for template negotiation
  • Miner proposes template; pool approves or rejects
  • Works with Slush Pool (Braiins) and others

Either way: You decide what transactions get mined.

Slide 11: Node Choice — Core vs. Knots (BIP-110 / RDTS)​

Bitcoin Core (default, permissive)

  • Accepts nearly all valid transactions (Ordinals, inscriptions)
  • Neutral mempool — doesn't judge transaction "purpose"

Bitcoin Knots (restrictive, BIP-110 / RDTS)

  • Limits data pushes >256 bytes, large scriptPubKeys
  • Goal: filter non-monetary data
  • Controversy: Censorship vs. protecting Bitcoin-as-money

Our take: You choose. Both work with template-control protocols.

Slide 12: Our Stack​

Braiins Hashpower (rented PH/s)
    ↓
DATUM endpoint (your node)
    ↓
Bitcoin Knots (mempool + templates)
    ↓
Ocean.xyz or Solo Pool (rewards)
    ↓
C-Lightning (Bolt 12 payouts)

Physical layer: StartOS on Dell OptiPlex 9020M

  • 2TB SSD, 16GB RAM — runs Knots + CLN + DATUM proxy

Slide 13: Hermes Agent — Privacy-Tiered AI​

The Problem: Most AI sends everything to the cloud. Your configs, keys, addresses → someone else's server.

Our Tiers:

TierModelLocationUse Case
T1Local QwenAgentorange (home)API keys, configs, wallet data
T2TryMapleE2E encrypted cloudFinancial CSVs, analytics
T3Opus / CloudOrchestration onlyPublic data, slide outlines

Rule: Raw sensitive data never touches T3. Keys live in Bitwarden, injected at runtime.

Slide 14: Live Demo — Hashrate Autopilot​

What you'll see:

  • Autopilot dashboard at http://<AUTOPILOT-HOST>:<PORT>/
  • Real-time market depth from Braiins Hashpower API
  • Automated bid placement when price crosses threshold
  • Routing logic: rented hash → DATUM endpoint → our node
  • (If time) One-click solo package spin-up

Slide 15: Economics & Risks (Quick)​

Costs: ₿0.47–0.62 / EHs/day ($47–62 at $100k/BTC)

Risks:

  • Bid may sit unfilled if price spikes
  • Solo mining = lottery, not investment
  • API key compromise → rotate immediately

Mitigations: Start small (10k sats). Use DATUM failover. Monitor locally.

Slide 16: Call to Action​

Tonight:

  • Sign up at hashpower.braiins.com (10k sats min)
  • Try a one-click solo package
  • If you run a node, spin up DATUM

This Month:

  • Join @braiinshashpower on Telegram
  • Read the wiki on agentorange: <WIKI-HOST>:/path/to/wiki/>

Long Term: More hash rate under miner-controlled templates. Less pool centralization. Bitcoin wins.

Slide 17: Resources​

Slide 18: Q&A​

Title: Questions? Subtitle: Let's talk hash markets, node setups, and keeping AI out of your wallet.

Appendix: Speaker Notes​

Slide 5 (Centralization): Mention Foundry/DMND dominance. Reference Ocean.xyz as the exception. Slide 11 (Core vs Knots): Keep brief and neutral. Acknowledge debate exists; both paths work for template control. Slide 13 (Hermes): Emphasize this isn't theoretical — we use this every session. Slide 14 (Demo): If Autopilot is unreachable (Tailnet), fall back to screenshots of market.braiins.com + terminal DATUM logs. Slide 11 (BIP-110): RDTS = proposed temporary softfork. 0% miner signaling currently. Ideological debate: money vs. platform.
