So basically our factory opens our decentralized application and connect with MetaMask account and manufacturer will fill the product information and create QR code and create a hash embedded with QR code. That hash is inserted into the chain and QR code can attach to the product. And basically before when it actually generate the hash, that hash must be signed using the MetaMask account. MetaMask account basically, then our decentralized system will connect with the alchemy provider. It can be any provider, but we use alchemy here. Existing provider and we must need a smart contract to verify or push the hash into the chain. Then It will store in the blockchain, immutable blockchain, which is also transparent. Anyone in the chain can check the product authenticity. So basically the hash will embed it with the QR code. Thats the last step. So in the verification step, anyone can use their device using our application. Through our application, they can scan the QR code and check the product authenticity. It will basically compare the stored hash and the current product information and show the product authenticity results. So in the recycling part, a buyer actually returns the product to Store. When it returns the product to Store, Store will again scan the QR code. At that time, from the product information, the amount of the product will be automatically calculated and the calculated rewards will be sent to the buyers. Accordingly, these are the similar steps. And the last step in the factory, actually government authority here, the government authority can monitor each of the actor, like from manufacturer to buyer. So according to the performance of the manufacturer, government can waive their taxes. |
