Permission System Architecture
The Torus v0.5 implements a flexible recursive delegation system called Permission0 that enables fine-grained control over emission distribution, agent capability access, and governance functions.
Permission Architecture Overview
The permission system operates through Permission Contracts that define delegation relationships between delegators and recipients. Each contract encapsulates the authority, scope, duration, and enforcement mechanisms for specific permission delegations.
Permission Contract Structure
pub struct PermissionContract { pub delegator: AccountId, // Authority delegator pub recipient: AccountId, // Authority recipient pub scope: PermissionScope, // Delegation boundaries pub duration: PermissionDuration, // Temporal constraints pub revocation: RevocationTerms, // Termination conditions pub enforcement: EnforcementAuthority, // Third-party governance pub parent: Option<PermissionId>, // Recursive delegation chain}Permission Scope Categories
The system supports three fundamental permission types that enable comprehensive coordination:
pub enum PermissionScope { Emission(EmissionScope), // Token delegation permissions Curator(CuratorScope), // Governance function delegation Capability(CapabilityScope), // Off-chain service access control}Recursive Delegation Architecture
The permission system enables recursive delegation through hierarchical permission trees, creating natural incentive alignment across agent networks.
Hierarchical Permission Trees
Recursive Delegation Properties:
- Unlimited Depth: Delegation trees can extend to arbitrary depth
- Permission Inheritance: Child permissions derive authority from parent permissions
- Validation Chains: Each level validates the delegator has rights from the level above
- Economic Incentives: Rational agents delegate when it increases their own emissions
Delegation Validation
Each delegation level undergoes strict validation to ensure proper authorization:
- Parent Validation: Child permissions must reference valid parent permissions
- Authority Checking: Each delegation level validates proper authorization chain
- Scope Consistency: Child permissions cannot exceed parent permission scope
- Temporal Constraints: Child permissions cannot exceed parent permission duration
Enforcement Authority System
The enforcement system creates a sophisticated bridge between on-chain permissions and off-chain verification, allowing builders to create custom enforcement mechanisms.
