Since the start of Blockchain technology in 2008, its application has expanded across various sectors to ensure reliable and secure data transmission, from its use in Bitcoin to the rise of Blockchain as a Service (BaaS), a modern trend enabling organizations to develop applications on cloud-based networks. Notably, blockchain has been crucial in developing robust applications, with its popularity steadily increasing. It not only addresses the doublespending problem but also independently verifies the accuracy of transactional data. Serving as the foundation of all applications, blockchain technology guarantees data integrity. This study demonstrates the integration of decentralized blockchain technology and supply chain methodologies, showing that end-users no longer solely rely on intermediaries or third parties to confirm product authenticity. This implementation significantly impacts revenue, brand reputation, and profitability. Through a distributed ledger, genuine and counterfeit products can be distinguished. The study introduces an anti-counterfeiting decentralized blockchain solution, empowering manufacturers to deliver authentic goods without direct oversight. This is achieved by authenticating products at each stage of the supply chain. For every product added, a unique QR code is generated and stored in the database, ensuring transparency and traceability throughout the supply chain.
