What this diagram shows

This diagram illustrates a complete agricultural supply chain, detailing the steps and interactions for farmers, distributors, retailers, and customers. It highlights the integration of blockchain technology for product registration, tracking, and verification at each stage, from adding crop details and generating QR codes to scanning, updating blockchain records, and finally, customer verification and purchase.

When to use it

Use this diagram to understand or design a transparent and traceable supply chain system, especially for agricultural products. It's suitable for projects involving blockchain for provenance, quality assurance, and consumer trust. Ideal for stakeholders needing to visualize the flow of goods and information across multiple parties.

How to adapt it for your project

To adapt this diagram, you can modify specific stages to fit different industries (e.g., pharmaceuticals, luxury goods). Add more detailed sub-processes within each role (e.g., quality checks, payment processing). Integrate other technologies like IoT sensors for environmental data or AI for demand forecasting. Adjust the blockchain interaction points based on the specific smart contract logic or platform used.
