# Supply Chain

> Use Aqua Protocol for transparent and verifiable supply chain tracking

# Supply Chain

Aqua Protocol provides comprehensive supply chain tracking and verification capabilities that ensure transparency, authenticity, and traceability throughout the entire supply chain process.

## Overview

Supply chain tracking with Aqua Protocol enables:

* **End-to-end traceability** of products and materials
* **Tamper-proof verification** of supply chain events
* **Transparent audit trails** for compliance and reporting
* **Decentralized verification** without centralized authorities
* **Real-time tracking** and monitoring capabilities

## Use Cases

### Food and Agriculture

* **Food safety** and traceability
* **Organic certification** and verification
* **Farm-to-table** tracking
* **Recall management** and safety

### Pharmaceuticals

* **Drug authenticity** and verification
* **Cold chain** monitoring and compliance
* **Regulatory compliance** and reporting
* **Counterfeit prevention** and detection

### Manufacturing

* **Component tracking** and verification
* **Quality control** and assurance
* **Supplier verification** and compliance
* **Production monitoring** and optimization

### Logistics and Transportation

* **Package tracking** and verification
* **Route optimization** and monitoring
* **Delivery confirmation** and proof
* **Cargo security** and protection

## Implementation Examples

### Basic Supply Chain Tracking

```javascript theme={null}
import { AquaClient } from '@aqua-protocol/sdk';

const client = new AquaClient({
  apiKey: process.env.AQUA_API_KEY,
  endpoint: 'https://api.aqua-protocol.org/v3'
});

// Track product through supply chain
const trackProduct = async (productId, location, status, handler) => {
  const trackingData = {
    productId,
    location,
    status,
    handler,
    timestamp: new Date().toISOString()
  };
  
  // Notarize tracking data
  const notarization = await client.notarize({
    content: JSON.stringify(trackingData),
    metadata: {
      type: 'supply_chain_tracking',
      productId: productId,
      location: location,
      status: status
    }
  });
  
  return notarization.verificationHash;
};

// Verify product authenticity
const verifyProduct = async (productId) => {
  // Get all tracking records for product
  const trackingRecords = await getTrackingRecords(productId);
  
  const verificationResults = [];
  
  for (const record of trackingRecords) {
    const verification = await client.verify({
      verificationHash: record.verificationHash,
      content: JSON.stringify({
        productId: record.productId,
        location: record.location,
        status: record.status,
        handler: record.handler,
        timestamp: record.timestamp
      })
    });
    
    verificationResults.push({
      record,
      verification
    });
  }
  
  return verificationResults;
};
```

### Product Creation and Tracking

```javascript theme={null}
// Create product in supply chain
const createProduct = async (productData) => {
  const product = {
    productId: productData.productId,
    name: productData.name,
    category: productData.category,
    manufacturer: productData.manufacturer,
    created: new Date().toISOString()
  };
  
  // Notarize product creation
  const notarization = await client.notarize({
    content: JSON.stringify(product),
    metadata: {
      type: 'product_creation',
      productId: product.productId,
      category: product.category
    }
  });
  
  return {
    product,
    verificationHash: notarization.verificationHash
  };
};

// Track product movement
const trackMovement = async (productId, fromLocation, toLocation, handler) => {
  const movement = {
    productId,
    fromLocation,
    toLocation,
    handler,
    timestamp: new Date().toISOString(),
    status: 'in_transit'
  };
  
  const notarization = await client.notarize({
    content: JSON.stringify(movement),
    metadata: {
      type: 'product_movement',
      productId: productId,
      fromLocation: fromLocation,
      toLocation: toLocation
    }
  });
  
  return notarization.verificationHash;
};
```

### Quality Control Integration

```javascript theme={null}
// Quality control verification
const qualityControl = async (productId, qualityData) => {
  const qualityRecord = {
    productId,
    qualityData,
    inspector: qualityData.inspector,
    timestamp: new Date().toISOString(),
    status: qualityData.passed ? 'passed' : 'failed'
  };
  
  const notarization = await client.notarize({
    content: JSON.stringify(qualityRecord),
    metadata: {
      type: 'quality_control',
      productId: productId,
      status: qualityRecord.status
    }
  });
  
  return notarization.verificationHash;
};

// Temperature monitoring
const temperatureMonitoring = async (productId, temperatureData) => {
  const temperatureRecord = {
    productId,
    temperature: temperatureData.temperature,
    location: temperatureData.location,
    timestamp: new Date().toISOString(),
    status: temperatureData.temperature < 4 ? 'safe' : 'unsafe'
  };

## Analytics and Reporting

### Supply Chain Analytics

```javascript theme={null}
// Supply chain analytics
class SupplyChainAnalytics {
  constructor(aquaClient) {
    this.client = aquaClient;
  }

  async getProductJourney(productId) {
    const journey = await this.getTrackingRecords(productId);
    
    return {
      productId,
      totalEvents: journey.length,
      duration: this.calculateDuration(journey),
      locations: this.extractLocations(journey),
      quality: this.analyzeQuality(journey)
    };
  }

  async getQualityMetrics(productId) {
    const qualityRecords = await this.getQualityRecords(productId);
    
    return {
      productId,
      totalTests: qualityRecords.length,
      passedTests: qualityRecords.filter(r => r.passed).length,
      failedTests: qualityRecords.filter(r => !r.passed).length,
      averageScore: this.calculateAverageScore(qualityRecords)
    };
  }

  async getTemperatureAnalysis(productId) {
    const temperatureRecords = await this.getTemperatureRecords(productId);
    
    return {
      productId,
      averageTemperature: this.calculateAverageTemperature(temperatureRecords),
      minTemperature: Math.min(...temperatureRecords.map(r => r.temperature)),
      maxTemperature: Math.max(...temperatureRecords.map(r => r.temperature)),
      violations: temperatureRecords.filter(r => r.temperature > 8).length
    };
  }
}
```

### Compliance Reporting

```javascript theme={null}
// Compliance reporting
class ComplianceReporter {
  constructor(aquaClient) {
    this.client = aquaClient;
  }

  async generateComplianceReport(productId, startDate, endDate) {
    const report = {
      productId,
      period: { startDate, endDate },
      totalEvents: 0,
      qualityEvents: 0,
      temperatureEvents: 0,
      violations: 0,
      compliance: 'COMPLIANT'
    };
    
    const events = await this.getEventsInPeriod(productId, startDate, endDate);
    
    report.totalEvents = events.length;
    report.qualityEvents = events.filter(e => e.type === 'quality_control').length;
    report.temperatureEvents = events.filter(e => e.type === 'temperature_monitoring').length;
    report.violations = events.filter(e => e.violation).length;
    
    if (report.violations > 0) {
      report.compliance = 'NON_COMPLIANT';
    }
    
    return report;
  }

  async generateAuditTrail(productId) {
    const auditTrail = await this.getAuditTrail(productId);
    
    return {
      productId,
      totalRecords: auditTrail.length,
      records: auditTrail.map(record => ({
        timestamp: record.timestamp,
        event: record.event,
        handler: record.handler,
        verificationHash: record.verificationHash
      }))
    };
  }
}
```
