Issue #8: Access Control & Permission System

[PeterOche]

Description

Develop a comprehensive access control system with role-based permissions, modular access rights, and security features.

Tasks

• Create Role model with permission levels:
  • role_id (u32)
  • role_name (felt252)
  • permissions (u256 bitmask)
  • min_reputation_required (u256)
• Create UserRole mapping system
• Implement permission checking functions
• Build role assignment and revocation system
• Create admin role management
• Add emergency access controls
• Implement time-based permissions (temporary roles)
• Create permission inheritance system
• Add multi-signature requirements for critical operations

Acceptance Criteria

• Role-based permissions are properly enforced
• Admin functions require appropriate authorization
• Emergency controls can be activated when needed
• Temporary permissions expire correctly
• Multi-signature requirements work for critical operations
• Permission changes are properly logged
• System is resilient against privilege escalation attacks

Dependencies

• Issue Backend Scaffold: Node.js with NestJs and TypeScript #4 (Reputation Scoring System)
