Abstract:

Fake products have become a major concern for businesses and consumers alike, resulting in significant economic losses and potential risks to consumers. Traditional methods of product authentication often fall short in the face of sophisticated counterfeit operations. Blockchain technology, with its decentralized and immutable nature, offers a promising solution to tackle this issue. This article provides a comprehensive overview of the use of blockchain for fake product identification. It begins by discussing the prevalence and impact of counterfeit products on various industries, highlighting the urgent need for an effective anti-counterfeiting system. The paper uses the fundamentals of blockchain technology, explaining its core concepts and features that make it suitable for this application. Next, the paper explores the key components of a blockchain-based system for fake product identification, including product registration, supply chain tracking, and consumer verification. It examines how blockchain can provide a tamper-proof and transparent ledger for recording and verifying product information at each stage of the supply chain. Additionally, the paper analyzes various consensus mechanisms and smart contract functionalities that enhance the security and efficiency of the system. The article also addresses the challenges and limitations associated with implementing blockchain-based anti-counterfeiting solutions, such as scalability, interoperability, and user adoption. It discusses potential strategies and emerging technologies that can mitigate these challenges and drive widespread adoption of blockchain for product authentication.
