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.

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

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
