Arrayan

Arrayan is a Food Supply Chain application built on the blockchain fabric of Resilient DB that tracks the products, by-products, and process history through the Food Supply Chain.

Modifications

We have modified the existing Resilient DB GraphQL APIs catering the needs of a blockchain-based food supply chain and added a new API to fetch the products in the forked repo
