[**dVIN Labs** ](https://www.dvinlabs.com)has deployed a production blockchain system for wine that demonstrates these digital product passport concepts at scale:

#### Digital Cork™ NFTs:

* Each physical bottle is paired with a **unique digital twin NFT**—the Digital Cork—recorded on blockchain
* Records origin, production details, authenticity, and complete custody history
* Functions as **certificate of authenticity** that buyers, distributors, and insurers can instantly verify

#### Decentralized Physical Infrastructure (DePIN):

* **Hardware layer:** RFID/NFC tags, temperature and humidity sensors, and decentralized scanning nodes track bottles at every custody point—vineyard, bonded warehouse, shipping, retail, and cellar
* **Blockchain anchoring:** Verified events and sensor data are anchored to blockchain, creating **immutable, timestamped records** of chain of custody and environmental conditions
* **Economic incentives:** Infrastructure operators, validators, and logistics partners earn **$VIN tokens** when they contribute verified data, aligning economic interests with supply chain visibility

#### Condition Tracking with Quality Signals:

* System continuously monitors **temperature, humidity, and handling quality**
* Flags deviations and produces simple **quality indicators ("Green/Yellow/Red")** that signal risk points to stakeholders in real-time
* Reduces spoilage losses by **highlighting quality threats during transit and storage**

#### Lifecycle Engagement & Data Monetization:

* When a bottle is opened, the Digital Cork is **"uncorked" (burned on blockchain)** and replaced with **Tasting Tokens™**
* Captures consumption events and unlocks rich consumer engagement data
* Producers and distributors gain granular insights into where, how, and by whom wines are consumed, enhancing marketing, inventory planning, and consumer loyalty programs

#### Component 3: Loyalty Certificate Functionality

* Consumers can **donate to support specific farmers, companies, or projects**
* Receive **loyalty certificate in app** as proof of support
* Can show friends and family their support for specific producers
* Example: Supporting vineyard's project building schools in community
* Creates **direct economic relationships** between conscious consumers and producers

### Consumer Experience: Pre-Consumption and Post-Consumption Engagement

#### Pre-Consumption Verification (dVIN Digital Cork Example):

1. **Scan RFID/NFC tag or QR code** on bottle
2. **Access Digital Cork NFT** showing complete verified history:
   * Vineyard GPS coordinates and microclimate data
   * Exact harvest date and grape quality metrics
   * Fermentation temperatures and aging duration
   * Bottling date and handling history
   * **Real-time quality indicator (Green/Yellow/Red)** based on storage conditions throughout entire distribution chain
   * Every custody handoff (all 7-10 transfers) with timestamps
   * Cryptographic proof of authenticity via blockchain

#### Post-Consumption Engagement (dVIN Tasting Tokens Example):

3\. **When bottle is opened:** Digital Cork is "uncorked" (burned on blockchain)

4\. **Tasting Tokens™ are issued:** Capture consumption event and unlock consumer engagement

5\. **Data flows back to producer:**

* Where wine was consumed (geography)
* When it was consumed (timing insights)
* Consumer can rate and provide direct feedback
* Producers gain granular insights for marketing, inventory planning, and loyalty programs

**Business Value:** Capture **full premium pricing** for quality products by providing verifiable proof. **Eliminate counterfeit competition**. Build consumer trust that translates directly to revenue.
