Counterfeit or replicate goods and commodities production and selling risk customers' finances, safety, and health. It further impacts the original manufacturer's economic growth through such things as loss of revenue, defamation of product, downtime, replacement cost, compelling brands to incur funds to fight fakes, compromising business partners' trust, robbery of sales, etc. In response to this, we outline an SHA-256 algorithm-secured blockchain system that verifies products with QR codes and barcodes. The method uses a camera scanner to verify the product's serial code, which is on a tamper-proof blockchain, authenticating every item's authenticity by the cryptographic strength of SHA-256. If the code in a scanned product is identical with the blockchain entry, the customer is notified of its authenticity; inconsistencies notify the customer and, with permission, the manufacturer of the counterfeit state. This method greatly minimizes reliance on merchant guarantees, offering customers direct validation powers while ensuring manufacturers' interests with an open, secure, and impenetrable confirmation process against forged products.
