I would like some help in building a website using solidity with a timed smart contract that manages the transactions and notes the ownership changes of the 4 players (producer, transport, wholesale, consumer) to ensure transparency of object(for instance apple)'s exchange through the supply chain. I am skilled in web-development and am mostly looking for help with how to work with the smart contract and code the smart contract itself. I need to ensure that each of the 4 players have authentication rights to the website that allows each one of them to pass ownership of good to the other player with set time conditions. The time is used against a counter to ensure that our final good doesn't expire before it's sold. Need the work done in 1 day. Thank you!
