This repository containts an Ethereum DApp that demonstrates a Supply Chain flow between a Seller and Buyer. The user story is similar to any commonly used supply chain process. A Seller can add items to the inventory system stored in the blockchain. A Buyer can purchase such items from the inventory system. Additionally a Seller can mark an item as Shipped, and similarly a Buyer can mark an item as Received.
The coffee beans are harvested by the farmers, are then sold to the distributors, and the distributors then distribute them to the retailers, and finally, the consumer purchases them.
