DAPP that verifies product record using blockchain
About
The product Verification Dapp is a Decentralized Application that acts as a proof of existence for an external entity such as a book in a Library or a clothing product which can be tracked across various branches/stores of a brand. The product details can be stored on a document which can contain the unique Product-ID, Bar-code and various other differentiators and properties. This Dapp can then be used to store a cryptographic hash of the document containing details of the product. Users can verify the existence and validity of a product whose digital hash is stored in a blockchain. The client side of the Dapp will compute a cryptographic hash depending on the contents of the document. The time-stamp along with the document hash is then submitted to the smart contract associated with the dapp. The cryptographic hash depends on the document’s contents and any change to the contents will change the hash and hence will fail during verification.
