Blockchain can help address counterfeiting, because it ensures the origins of products. Blockchain offers a secure and trusted system for tracking materials from the beginning of the manufacturing process to your doorstep. Blockchain essentially helps identify where items come from, so with this technology law enforcement can more easily establish if products are counterfeit, as well as companies can better protect their intellectual property. QR codes can be scanned to view the block on the blockchain that contains the product information. If you scan the QR code on a product using your smartphone, it will search for matches in the Blockchain database. If there is a match, it will let you know whether or not the product is authentic. For privacy reasons, there is no information storage outside of the Blockchain database.
