Counterfeiting of goods has been a nightmare to manufacturers. Not only does it reduce returns for a manufacturing company, it also tarnishes the name of a company and their product, as counterfeits are less durable than authentic goods made by the manufacturers. This might in the long run make customers start loosing faith in the product. Blockchain is the ultimate answer to this. when a goods is manufactured, a block should be addled to the chain. on this block would be recorded important details of the product like name of product, manufacturer, production date expiring date etc. attached to the product would be a scan-able QR code (hash of its block). as the product moves through the supply chains more transactions are recorded on the blockchain. This way when a buyer wants to buy the product, he can validate if the product is coming from the authentic manufacturer OR NOT.
