# Pattern 2: Supply Chain Management + Provenance Tracking

<figure><img src="/files/RybuYUlqYW8g2Ze0DZ6g" alt=""><figcaption></figcaption></figure>

**What Connects:** Your existing SCM platform → Blockchain verification layer → Permanent supply chain records

**How It Works:**

1. Supply chain **events occur in your SCM system** (exactly as they do now):
   * Raw material sourcing
   * Manufacturing steps
   * Quality inspections
   * Logistics handoffs
   * Facility transfers
2. For **products requiring verification**, SCM system sends event data to blockchain adapter:
   * Event type (sourcing, manufacturing, inspection, etc.)
   * Location (GPS coordinates or facility ID)
   * Timestamp
   * Certifications/compliance status
   * Party responsible
   * Product batch/serial number
3. Blockchain adapter **writes to blockchain**
4. Each **event receives blockchain transaction ID**
5. Events chain together to create **complete provenance record**
6. **Product packaging includes QR code** linking to full blockchain trail

**Consumer Experience:**

* **Scan product QR code**
* See **complete journey from source to store**
* **Verify** sustainability/ethical claims

**Supply Chain Partner Experience:**

* Each partner records their step on blockchain
* **Everyone sees same immutable records**
* **Disputes eliminated** (shared truth)
* **Automated compliance verification**
* **Instant recall identification**

**Integration Complexity: Medium**

* **SCM system adds:** API calls at key supply chain events
* **Blockchain adapter:** Provided by solution vendor
* **Partner onboarding:** Suppliers add blockchain recording at their steps
* **Typical integration time:** 3-6 months (includes partner coordination)

**Business Value:** Enable **premium pricing** for verifiable sustainability, **reduce counterfeiting** losses, **accelerate recall** response from weeks to minutes.
