# QuDAG Protocol 🌐
> The Darkest of Darknets - Built for the Quantum Age
QuDAG is a revolutionary quantum-resistant distributed communication platform built on a Directed Acyclic Graph (DAG) architecture. Unlike traditional blockchain systems that use linear chains, QuDAG uses a DAG structure for parallel message processing and consensus, enabling high throughput while maintaining cryptographic security against quantum computing attacks. **The platform is uniquely suited for distributed agentic systems and swarms**, providing the secure, decentralized infrastructure needed for autonomous AI agents to coordinate and communicate at scale.
The platform creates a decentralized mesh network where messages are processed through a DAG-based consensus mechanism and routed through multiple encrypted layers (onion routing), making communication both scalable and anonymous. **What makes QuDAG truly unique is its built-in dark domain system** - allowing you to register and resolve human-readable `.dark` addresses (like `myservice.dark`) without any central authority, creating your own darknet namespace with quantum-resistant authentication.
Built with an **MCP-first approach**, QuDAG seamlessly integrates with modern AI development workflows through the Model Context Protocol, providing native support for stdio/HTTP transports, comprehensive CLI tools, SDK libraries, and RESTful APIs. This makes it the ideal backbone for next-generation distributed AI systems that require both quantum-resistant security and high-performance communication.
Think of it as combining the anonymity of Tor with the decentralization of Bitcoin, but built for the quantum age and optimized for high-performance communication rather than financial transactions - all while providing first-class support for AI agent coordination and swarm intelligence.
**Key Highlights:**
- 🔒 Post-quantum cryptography using ML-KEM-768 & ML-DSA with BLAKE3
- ⚡ High-performance asynchronous DAG with QR-Avalanche consensus
- 🌐 Built-in `.dark` domain system for decentralized darknet addressing

```
### 🪙 rUv Token Economics
**Resource Utilization Vouchers (rUv)** are the native tokens for computational resource trading:
- **Purpose**: Facilitate trustless exchange of computational resources between agents
- **Quantum Security**: All transfers protected with ML-DSA signatures
- **Precision**: 64-bit integer precision for micro-transactions
- **Supply**: Configurable maximum supply with mint/burn operations
- **Integration**: Native support in QuDAG DAG consensus system
#### Token Operations
```bash
# Create account and manage tokens
qudag exchange create-account --name alice
qudag exchange balance --account alice
qudag exchange transfer --from alice --to bob --amount 1000
qudag exchange mint --account alice --amount 5000
qudag exchange supply
```
### 📊 Dynamic Tiered Fee Model
The exchange implements a sophisticated mathematical fee model that incentivizes agent verification and rewards high-usage participants:
#### Fee Structure
| Agent Type | Base Fee | Maximum Fee | Usage Behavior |
|------------|----------|-------------|----------------|
| **Unverified** | 0.1% | 1.0% | Increases with time and usage |
| **Verified** | 0.25% | 0.50% → 0.25% | Decreases with high usage |
#### Mathematical Formulation
**Unverified Agent Fee:**
```
f_unv(u,t) = F_min + (F_max - F_min) × α(t) × β(u)
where:
α(t) = 1 - e^(-t/T) # Time phase-in (3 months)
β(u) = 1 - e^(-u/U) # Usage scaling (10,000 rUv threshold)
```
**Verified Agent Fee:**
```
f_ver(u,t) = F_min_ver + (F_max_ver - F_min_ver) × α(t) × (1 - β(u))
# Rewards high usage with lower fees
```
#### Fee Examples
| Scenario | Time | Usage | Fee Rate | Description |
|----------|------|-------|----------|-------------|
| New unverified agent | 0 months | 0 rUv/month | 0.100% | Introductory rate |
| Moderate unverified | 3 months | 5,000 rUv/month | 0.324% | Standard progression |
| High-usage unverified | 6 months | 50,000 rUv/month | 0.873% | Penalty for unverified high usage |
| New verified agent | 0 months | 0 rUv/month | 0.250% | Verified base rate |
| High-usage verified | 6 months | 20,000 rUv/month | 0.279% | Reward for verified high usage |
#### Configure Fee Parameters
```bash
# Update fee model parameters
qudag exchange configure-fees \
--f-min 0.002 \
--f-max 0.012 \
--f-min-verified 0.003 \
--f-max-verified 0.006 \
--time-constant-days 90 \
--usage-threshold 10000
# View current fee status and examples
qudag exchange fee-status --examples
# Calculate specific fees
qudag exchange calculate-fee --account alice --amount 1000
```
### 🔒 Immutable Deployment System
The exchange supports optional immutable deployment mode for governance-free operation:
#### Security Features
- **Quantum-Resistant Signatures**: ML-DSA-87 signatures lock configurations
- **Configuration Hashing**: Blake3 hashes ensure integrity
- **Grace Period**: Configurable grace period before enforcement (default 24 hours)
- **Emergency Override**: Optional governance keys for emergency situations
- **Atomic Locking**: All-or-nothing configuration locking
#### Deployment Workflow
```bash
# 1. Configure the exchange
qudag exchange configure-fees --f-min 0.001 --f-max 0.01
# 2. Deploy in immutable mode with 1-hour grace period
qudag exchange deploy-immutable --grace-period 1
# 3. Check deployment status
qudag exchange immutable-status
# During grace period (1 hour):
# - Configuration can still be modified
# - System shows "locked but not enforced"
# After grace period:
# - All configuration changes blocked
# - System operates in governance-free mode
```
#### Status Monitoring
```bash
# Detailed immutable deployment status
qudag exchange immutable-status --format json
```
Example output:
```json
{
"enabled": true,
"locked": true,
"enforced": true,
"in_grace_period": false,
"locked_at": "2025-06-22T15:30:00Z",
"grace_period_seconds": 3600,
"config_hash": "blake3:a1b2c3d4..."
}
```
### 🤖 Agent Verification System
Agents can be verified to receive reduced fees and enhanced privileges:
#### Verification Benefits
- **Lower Fees**: Reduced base fees (0.25% vs 0.1%)
- **Usage Rewards**: High usage decreases fees further
- **Priority Access**: Enhanced access to network resources
- **Trust Signals**: Cryptographic proof of verification status
#### Verification Process
```bash
# 1. Create verification proof file
cat > agent_proof.json << EOF
