Abstract: Counterfeit products are a major problem that affects businesses and consumers worldwide. They pose a threat to public safety, harm legitimate manufacturers, and result in significant economic losses. Authentifi is a decentralised platform that proposes a solution to this challenge by utilising blockchain technology to create a secure and transparent system for verifying product authenticity. The Authentifi platform enables manufacturers, retailers, and consumers to verify the authenticity of products, thereby reducing the prevalence of counterfeit goods. This research paper discusses the technical aspects of the Authentifi platform, including design and implementation. The paper evaluates the feasibility, efficiency, and security of the platform through a series of experiments and simulations. The platform's use of blockchain technology ensures that the information stored on the system is immutable, tamper-proof, and transparent, providing a high level of security. Authentifi's decentralisation also ensures that the system is resistant to single points of failure and malicious attacks. The experiments and simulations conducted demonstrate that Authentifi is an effective solution for counterfeit product identification. The platform's performance is compared with traditional methods of product identification, such as barcodes and QR codes. The simulations assess the platform's resilience to various attacks, including data breaches and denial of service attacks. Authentifi's benefits for manufacturers, retailers, and consumers include an increase in consumer confidence in the products they purchase, protection of legitimate manufacturers from losses due to counterfeiting, and improved public safety. The research suggests that Authentifi has the potential to significantly reduce the negative impact of counterfeit products on the global economy.....
