Counterfeiting in footwear a very big issue in the industry. This is a prevalent problem in sneakers due to the popularity and rarity of these footwear, this practice undermines consumer trust and brand reputation. In response, this blockchain-based sneaker authentication system proposes to solve this problem by using technologies such as decentralization and QR Codes embedded in sneakers to ensure that each step of the process from manufacturer to consumer is transparent and open. Manufacturers use the Ethereum blockchain to add sellers and their product. Each serial number of their products are mapped to a seller which then, using this secure platform can make a sale and map each pair of shoes to a consumer. This project utilizes advanced authentication algorithms, signature validation and Solidity contracts to enhance the system&s;s integrity. This proof of concept aims to instill confidence among consumers and the stakeholders (sellers, manufacturers) by identifying counterfeit products.
