How it's made

Challenges we ran into 1. Efficient data structure solidity does not have a set data structure that allows O(1) lookup, inserts and deletes of approved addresses. - Map each address to a struct whose boolean flag facilitates constant time lookup, inserts and deletes. 2. Storing sensor readings Choosing a long-term storage with reasonable pricing and transaction fees to supply chain members. - Ethereum events are lightweight, persistent and may be indexed to expedite search by product id. 3. Styling the frontend It is difficult and time-consuming to manually create css styles. - Use tailwindcss to quickly apply modern and minimalistic designs to enhance user experience.
