Bloxchain Protocol Security Documentation

Purpose: Comprehensive knowledge base of security threats and test coverage
Last Updated: February 21, 2026
Status: Production Ready

---

Overview

This documentation serves as both a security knowledge base and test reference guide for the Bloxchain Protocol. It consolidates attack vector analysis, security mitigations, and comprehensive test documentation into an organized, expandable structure.

Documentation Structure

📚 Attack Vectors Codex

Purpose: Knowledge library of security threats relevant to this project

A comprehensive catalog of attack vectors organized by category, including:

• Attack descriptions with detailed scenarios
• Current protections and mitigations
• Severity classifications (Critical, High, Medium, Low)
• Code locations where protections are implemented
• Verification requirements for each vector

Categories Covered:

1. Access Control & Authorization
2. Meta-Transaction Security
3. State Machine & Transaction Lifecycle
4. Reentrancy Attacks
5. Input Validation & Data Manipulation
6. Payment & Economic Security
7. Composite & Multi-Vector Attacks
8. Cryptographic & Signature Attacks
9. Time-Based Attacks
10. Role Management

How to Use:

• For Security Audits: Reference specific attack vectors and verify protections
• For Development: Understand security requirements when adding features
• For Testing: Identify test coverage gaps and required test scenarios
• For Learning: Study attack patterns and mitigation strategies

---

🔮 Test Documentation

Purpose: Complete documentation of all existing tests

A comprehensive reference of all test functions with:

• Test descriptions and purposes
• Attack vectors covered by each test
• Test file organization and structure
• Execution instructions and patterns
• Test status and coverage metrics

Test Categories:

1. Comprehensive Fuzz Tests (148 tests in 14 files; 309 total tests in 37 suites)
2. Unit Tests
3. Integration Tests
4. Security Tests
5. Invariant Tests

How to Use:

• For Test Execution: Understand what each test verifies
• For Test Maintenance: Know which tests cover which attack vectors
• For Test Development: Identify gaps and required new tests
• For Coverage Analysis: Map tests to attack vectors

Protocol-vulnerabilities-index-derived vectors are documented in the Codex: see §18 Protocol-Vulnerabilities-Index-Derived Vectors.

🚀 Test Execution Guide

Purpose: Complete guide for running the test suite

A practical guide for executing tests with:

• Quick start commands for common scenarios
• Detailed command reference for Foundry test options
• Execution strategies for different testing phases
• Troubleshooting common issues
• CI/CD configuration examples

How to Use:

• For Running Tests: Follow execution commands and strategies
• For CI/CD Setup: Use provided configuration examples
• For Troubleshooting: Reference common issues and solutions

Adding New Content

Adding New Attack Vectors

When a new attack vector is identified:

1. Add to Codex: Document in ATTACK_VECTORS_CODEX.md under the appropriate category
2. Include:
   • Attack description and scenario
   • Code locations affected
   • Current protections (if any)
   • Severity classification
   • Verification requirements
3. Update Index: Add to the table of contents

Adding New Tests

When a new test is created:

1. Add to Test Documentation: Document in TEST_DOCUMENTATION.md
2. Include:
   • Test function name and purpose
   • Attack vectors covered
   • Test file location
   • Execution notes
3. Link to Codex: Reference the attack vectors it covers
4. Update Coverage: Update test coverage metrics

Maintenance Guidelines

Regular Updates

• After Security Audits: Update codex with new findings
• After Test Additions: Update test documentation
• After Code Changes: Verify protections still apply
• After New Features: Assess new attack vectors

Version Control

• Keep documentation synchronized with code
• Document changes in commit messages
• Maintain changelog for significant updates

Core Documentation Files

This documentation folder contains the essential security and testing documentation:

• Attack Vectors Codex - Comprehensive catalog of all security threats and mitigations (includes §18 Protocol-Vulnerabilities-Index-derived vectors)
• Test Documentation - Complete reference of all test functions
• Test Execution Guide - Guide for running the test suite
