│ ALPENGLOW PROTOCOL CLAIMS │
│ │
│ ✓ 100-150ms finalization (100x faster) │
│ ✓ Dual-path consensus (80% / 60% quorums) │
│ ✓ 20+20 resilience (Byzantine + Crash faults) │
│ ✗ No machine-checked proofs (until now) │
│ │
│ ───────────────────────────────────────────────── │
│ │
│ OUR TASK: PROVE IT FORMALLY │
│ │
│ • Safety: No conflicting finalizations │
│ • Liveness: Guaranteed progress │
│ • Resilience: 20+20 fault tolerance │

│ NETWORK COMPOSITION: │
│ ┌────────────────────────────────────────────┐ │
│ │ ████████████████ Correct: 80% │ │
│ │ ████ Byzantine: 20% │ │
│ └────────────────────────────────────────────┘ │

│ BLOCK A: >40% Correct Stake │
│ ┌────────────────────────────────────┐ │

│ BLOCK B: ≥60% Total → ≥40% Correct Minimum │
│ ┌────────────────────────────────────┐ │
│ │ ████████████ Block B Voters (≥40%) │ │
│ └────────────────────────────────────┘ │
│ │
│ PIGEONHOLE PRINCIPLE: │
│ • Total correct stake: 80% │
│ • Block A needs: >40% │
│ • Block B needs: ≥40% │
│ • Cannot fit: 40% + 40% = 80% (exactly all) │
│ │
│ ∴ ANY TWO QUORUMS OVERLAP BY ≥20% │
│ ∴ NO CONFLICTING FINALIZATIONS POSSIBLE │
│ │
│ This is the foundation of Byzantine Fault Tolerance. │

│ │
│ MATHEMATICAL EQUIVALENCE: │
│ ∀ node, slot: │
│ votorState[node][slot] ≡ votorState_flat[<<node,slot>>] │

│ └────────────────────────────────────────────────┘ │
│ 0% 50% 100% │
│ │
│ QUORUM MATH: │
│ • 60% responsive → CAN achieve 60% quorum ✓ │
│ • 20% Byzantine → CANNOT achieve 60% quorum ✗ │
│ • Intersection: 60% + 60% = 120% → ≥20% overlap ✓ │
│ │
│ PROGRESS GUARANTEE: │
│ • Honest leader (60% probability) → 60% votes → Finalize │
│ • Byzantine leader → Timeout → 60% skip → Advance │
│ • Expected: 1.67 slots to honest leader │
│ • Worst case: 19Δ bounded finalization │
│ │
│ ∴ PROTOCOL MAKES PROGRESS DESPITE MAXIMUM FAULTS │

│ WHY FORMAL VERIFICATION MATTERS │
│ │
│ BLOCKCHAIN STAKES: │
│ • Solana TVL: ~$6 Billion (2024) │
│ • Alpenglow: Mainnet upgrade candidate │
│ │
│ THE RISK: │
│ ONE BUG = Network halt or double-spend │
│ │
│ THE SOLUTION: │
│ ONE PROOF = Mathematical certainty │

Tools You Can Use:
- PowerPoint/Keynote: Simple, fast for text slides
- Google Slides: Free, collaborative
- Canva: Beautiful templates (free tier sufficient)
- LaTeX Beamer: For mathematical precision (if time permits)
- Even simpler: White text on black PNG images (high contrast)
Recommended Approach:
- Use consistent dark background (black or dark blue)
- White text, high contrast
- Sans-serif font (Arial, Helvetica) for readability
- 1920x1080 resolution
- Export as PNG images
- Insert into OBS as "Image" sources
