ABSTRACT
This document indexes every identified structural attack against
Bitcoin and maps each to its formal proof, defense, and falsification
condition. Attack closure means: every identified attack has a defense
showing it fails structurally.
TABLE OF CONTENTS
SUPPORTS
This document provides the complete attack index for:
- [BGT-0001] Attacks A1, A2, A3, A4 (Attack Survival table)
- [BGT-0001] Claims P1-P7 (Properties defended against attacks)
ATTACK CLASSES
Four attack classes test Bitcoin's structural properties.

DEFENSE METHODOLOGY
Defense structure varies by TYPE. Classify first, then apply appropriate
method.
DEFENSE TYPES
TYPE DESCRIPTION EXAMPLES ---------- ----------------------------------- ------------------------- TECHNICAL Protocol property argument A1.1 Ossification, A1.7 Supply EMPIRICAL Data-driven refutation A1.4 Energy, A1.3 Hashrate ECONOMIC Market dynamics analysis A1.2 Fee Security, A4.x STRATEGIC Actor incentive game A2.x State, A3.x Capture HYBRID Multiple component types A1.5 Quantum
REQUIREMENTS BY TYPE
TECHNICAL EMPIRICAL ECONOMIC STRATEGIC
Steelman Required Required Required Required L3 Analysis Required Optional Optional See L4 L4 Analysis (L1-L4) No No No Required Game Matrix Optional No Optional Required Counter-Equilibrium No No No Required Evidence Optional Required Required Optional Falsification Required Required Required Required
UNIVERSAL SECTIONS (all types)
1. Steelman - Strongest form of the attack, attributed
2. Falsification - Observable, bounded condition that would invalidate defense
3. Confidence - High / Medium-High / Medium / Low
STRATEGIC DEFENSE SECTIONS (A2.x, A3.x, some A4.x)
1. Steelman
2. L4 Analysis - Full L1-L4 for each actor class
3. Game Matrix - 2x2 payoff structure
4. Nash - Equilibrium identification
5. Counter-check - Test for stable (Stay, Stay)
6. Evidence - Empirical support
7. Falsification
8. Confidence
TECHNICAL/EMPIRICAL/ECONOMIC SECTIONS
1. Steelman
2. L3 Analysis - Meta-motivation of critic (or skip if not needed)
3. [Type-specific analysis: logical derivation / data / economics]
4. Evidence - Required for EMPIRICAL, optional for others
5. Falsification
6. Confidence
CLOSURE CLAIM
Attack closure: Every structural attack maps to a defense showing Nash
equilibrium favors Bitcoin.
To challenge closure:
1. Identify attack not in index, OR
2. Show defense equilibrium is wrong, OR
3. Provide falsification condition that has been met

If a criticism does not appear above, classify it using
[BGT-DISPUTE] Section 3 (Dispute Taxonomy) and route to the
appropriate defense document.
