Abstract - Blockchain innovations have gained significant
crucial role in efficiency and decision-making. Blockchain technology is well suited for this purpose because it enables fast, shared, and transparent access to data stored on an immutable ledger. Access to this data is restricted to authorized participants within the network. A blockchainbased system can track orders, payments, documents, manufacturing details, and many other activities. Since all participants share a single, consistent view of the data, every stage of a transaction can be monitored from start to finish, increasing trust, improving efficiency, and creating new opportunities for optimization.
interest in recent years. One of the most widely discussed applications is in currency exchange; however, blockchain technology is not limited to digital currency alone and has the potential to influence various business sectors. It offers greater transparency and efficiency in large-scale transactions and can be effectively used to detect counterfeit products. In today’s market, a major concern for consumers is determining whether a product is genuine or counterfeit. The widespread presence of counterfeit goods has had a serious negative impact on economic growth. To address this issue, it is essential to provide transparency about products and make this information accessible to consumers. The increasing circulation of counterfeit and unsafe products worldwide is a growing concern, and blockchain technology represents a significant step toward eliminating this problem.
Blockchain also enables end-to-end visibility within supply chain management. Organizations can digitize physical assets and record them on a decentralized and permanent ledger, allowing assets to be traced from production through delivery and final use by the customer. This increased transparency improves visibility for both businesses and consumers.
The use of blockchain can reduce the production and distribution of counterfeit goods, but public awareness is also crucial. By ensuring proper manufacturing and packaging, each product can be assigned a unique digital code that serves as its identity. Through a package implementation process, the product code is scanned using an application, which then verifies whether the product is genuine or counterfeit.

1.INTRODUCTION Blockchain is a technique for storing cryptographically linked records across multiple parties within a shared network, making data tampering extremely difficult. Originally developed to support Bitcoin transactions, blockchain technology has since evolved into a powerful tool for many other applications. Each block contains a collection of verified transactions or records, along with a timestamp and a cryptographic hash. This hash is generated from the contents of the current block and the hash of the previous block, forming a secure and continuous chain.
