Supply Chain Quality Certification System
This real-world example demonstrates how to use IOTA Hierarchies to create a comprehensive supply chain quality and compliance certification system that enables global verification of product certifications, regulatory compliance, and quality standards across international borders.
Business Context
Global supply chains require verifiable quality certifications and compliance attestations to ensure product safety and regulatory compliance. The hierarchical structure enables:
- International standards organizations to establish certification frameworks
- Regional certifiers to delegate authority to local testing laboratories
- Testing labs to delegate to qualified inspectors
- Manufacturers and retailers to verify product certifications instantly
Trust Hierarchy
International Standards Consortium (Root Authority)
├── ISO Europe (Root Authority)
│ ├── German Testing Institute (Regional Certifier)
│ │ ├── Berlin Lab (Testing Lab)
│ │ │ └── Senior Inspector (Inspector)
│ │ └── Munich Lab (Testing Lab)
│ └── French Testing Institute (Regional Certifier)
└── ISO Americas (Root Authority)
├── US FDA Regional Office (Regional Certifier)
└── Canadian Health Authority (Regional Certifier)
Properties Defined
The system defines comprehensive certification properties covering:
- ISO Standards:
iso.9001(Quality Management),iso.14001(Environmental),iso.22000(Food Safety) - Product Certifications:
product.organic,origin.verified,batch.tested - Regional Compliance:
compliance.eu,compliance.fda,compliance.halal - Time Management:
expiry.datefor certification lifecycle - Quality Assurance: Batch-specific testing results with pass/fail/pending status
Prerequisites
- A funded IOTA account
- Access to an IOTA network (testnet, devnet, or local)
- Hierarchies client SDK installed
