Food suppliers in the U.S. must comply with U.S. Food and Drug Administration (FDA) Foreign Supplier Verification Program regulatory requirements before they can ship their products to market. Regulatory compliance is a high-focus area in which developers are looking to build applications that automate and standardize processes used to enforce and execute compliance. Blockchain presents an opportunity to do just that. For this use case, imagine that a supplier is transferring the food products to an importer who verifies that the supplier, country, and food type all match the correct identifiers. At the port of entry, the supplier is again checked against a list of known suppliers in a database (managed by the regulator). If the supplier is of type exempt, then the products are transferred to the retailer. If the supplier is non-exempt, the products are checked against a list of known food products in a database (managed by the regulator). If the food is an exempt product, then it is transferred to the retailer. If the food is non-exempt, the importer must conduct the hazard analysis (either independently or by using a third party). The supplier provides the hazard analysis report to the regulator. The regulator reviews compliance and transfers the products to the retailer. This pattern captures the regulatory compliance logic for the FDA Foreign Supplier Verification Program in a smart contract that’s deployed on a business network.

Provenance Tracking
It is difficult for big companies to keep track of every record, especially when it is a multi-national operation. This demeans every aspect of the company’s reliability and reputation. Blockchain-based solutions for provenance tracking makes it easy to access product information on demand using embedded sensors and RFID tags. The product can be tracked all the way back to its origins and traced from every point on the chain.
Inventory management
Companies often lose track of their inventory, how much room they have for storage, how much of their product is for sale on what shelf. This opens the doors for fraudulent behavior and poor data analytics. The distributed ledger is an ideal environment to manage products in multiple locations and share that data across all involved parties.
Identity verification
Blockchain identity verification is a popular use case for the technology. With universal blockchain identity, we don’t need a third-party to handle global business interactions and enter contracts that rely on trust alone that someone is who they say they are. A big part of the supply chain is not only the verification of goods and services but the person behind the promise. The immutable ledger can help to authenticate identity.
Shipping logistics
To operate a global supply chain, shipments need to move on time, and all parties should be in the know about where the materials are in the chain. Blockchain brings real-time tracking to all supply chain participants to view that accurate, tamper-proof data as it is automatically realized by GPS trackers. More efficient shipping routes can be constructed the more data the blockchain is able to securely manage. Distributed ledger technology makes for an ideal platform for managing every aspect of shipping logistics.
Procure-to-pay gap reduction
It is expensive and time intensive to get customers to pay for products that have already arrived in many cases. Blockchains can use smart contract technology to connect delivery logistics and payment into digital contracts that act as a financial service. Smart contracts can be written so that terms are payable upon receipt. Proof of delivery from a carrier will trigger the contract to invoice the customer automatically. In many cases, smart contracts can be used to hold funds in escrow and then are automatically released once the goods have been verified. Smart contract escrow can eliminate the procure-to-pay gap and create more trustless interactions.
Food Supply Chain
Foodborne illness would be easier to stop in its tracks thanks to the blockchain as a traceability platform. It would be simple to identify where all of the food goods had been distributed and what communities have consumed the contaminated goods. Without data and traceability, there is a lack of accountability in current models and a lack of trust as a result. Food source traceability could be potentially lifesaving for some consumers.
Automotive Supply Chain
An entire vehicle history could be stored on the immutable, tamper-proof blockchain to make purchasing a used vehicle trustless or preserve the resale value of your new vehicle. Being able to document all repairs on a car via public ledger helps future buyers know the value and for owners to receive the exact value of the vehicle. Counterfeiting is also a significant issue in the automotive industry. Counterfeit spare parts are a costly occurrence that ruins brand reputations and can put drivers in dangerous situations. Digital identification for spare parts can up the transparency ante.
