Fictitious Merchandise Detection Using Blockchain

Nowadays we are seeing that the merchandise (product) we are buying can have (20-25) % chances that it can be fictitious merchandise. And this also affects the sales of the company. This paper discusses an application called "Fictitious Merchandise Detection Using Blockchain" to avoid the situation of Fake Products. Blockchain is a decentralized distributed ledger, any updating cannot be a part of this ledger. Blockchain consists of blocks that have their own hash value produced by an algorithm known as SHA-512 or SHA-256. This is an independent ledger I.e., it does not depend upon third parties. So here we are using a QR code scanner that will scan the QR code provided by the user then, it will match that QR code with the blockchain database. If it is matched, a popup message will be generated "Concrete Merchandise" otherwise "Fictitious Merchandise" will be generated as a popup message.
