Developing a Decentralized Applications (DApps) incorporating the features of smart contracts in blockchain In this task, you will develop a decentralized application with required smart contract(s) and deploy it on blockchain. You also need to create necessary front-end interfaces (as applicable) to interact with the deployed smart contract(s). The application allows a number of friends (maximum 10 and minimum 3) to start a new company. All of the friends must contribute an equal percentage of investment for the company and one of them becomes the manager of the company. Whenever the manager of the company needs any thing to purchase for the company, he requires the approval from his friends. If the manager receives the positive approval from at least 50% (of the total number of friends), then the manager can purchase the required product and make a transaction with the selected store (to complete the purchase). You need to make a video demonstrating each functionalities of this task and submit the video with all source codes (the source codes need to be commented properly).
