allowing them to check product details and establish a level of trust in the product's legitimacy. Counterfeit items must be identified in the supply chain since, in the pharmaceutical industry, if this is not done, the customer may be put at grave risk.
in recent years, as we all know. Counterfeiting is a global problem that affects social and economic growth worldwide, accounting for 3.3% of global commerce, according to OECD figures. These items are sometimes referred to as "first copies," and they can be marketed in place of original products. We have various online purchasing platforms such as Flipkart, Amazon, and others where customers buy things, which are then sent by the manufacturer and delivered to the consumer. However, many third parties are engaged in the process between manufacturing and delivery, such as warehouses. Because these third parties are engaged, unlawful product tampering may occur, resulting in losses for both the corporation and the customer. The primary goal of this project is to identify counterfeit items and ensure efficient product delivery processes. Counterfeiting may be dangerous in some businesses, such as the medical industry, thus identifying counterfeit items and stopping them from being sold is critical. A blockchain is a decentralized ledger that records all peer-topeer transactions. Participants can confirm transactions without the requirement for a centralized authority using this technology. Fund transfers, trade settlement, voting, and a variety of other challenges are all possible uses. We are attempting to introduce this immutable technology to identify counterfeit products in this project. QR codes are also used to store hash codes and determine their authenticity.
To avoid this, we are employing blockchain technology, which is immutable and decentralized and may be very useful in detecting fake products. If a third party is involved in tampering with the data, we can easily identify it using this technology. We also implemented a QR code that the consumer scans to evaluate if the product is genuine or counterfeit. 1.1 Blockchain: A blockchain is a continual record, known as a block, that is cryptographically linked together. A cryptographic hash of the preceding block, a timestamp, and transaction data are all included in each block. The timestamp verifies that the transaction data existed at the moment the block was released, allowing the hash to be calculated. Because each block contains information about the one before it, they create a chain, with each new block strengthening the preceding ones. As a result, blockchains are resistant to data tampering since the data in any one block, once recorded, cannot be changed retrospectively without affecting all subsequent blocks.

1. INTRODUCTION Fake products have a significant detrimental influence on the market for both consumers and sellers. The sellers fail to provide the goods as per the buyers' expectations, and the consumers begin to suspect the company's quality and standards, resulting in poor marketing of the brand whose counterfeit items are being distributed in the market. The most dangerous aspect of counterfeit items is that they may be extremely detrimental to users. Because fake or counterfeit items are not limited to any single area of the market, we must recognize these products and find a strategy to keep them out of the market. When we examine dominating sectors like pharmaceuticals and food supplies, these items may be quite risky. To address such issues, we
