Blockchain-Based Supply Chain Tracking System Implementation of a Decentralized Smart Contract on Ethereum

In today’s global economy, effective supply chain management is essential for product transparency, traceability, and security. Traditional products often rely on centralized data, which leads to drawbacks such as errors, fraud, and inefficiency. This project offers an on-chain solution using Ethereum smart contracts to overcome these challenges. Using blockchain technology, our system records all transactions of products in an immutable ledger, increasing accountability and transparency of the owners without the need for an intermediary. Unlike existing platforms that incur high operating costs, our solutions are designed to be lightweight and flexible, suitable for use by small and medium-sized businesses (SMEs). The approach includes the creation of smart contracts, real-time data integration via QR codes, and rigorous testing to ensure the accuracy and usability of the system. Conceptually, our approach is designed to improve product quality, reduce the risk of fraud, and ensure compliance with business regulations. Finally, the project aims to redefine supply chain management by leveraging blockchain technology to create a more secure, efficient and reliable system that will benefit all stakeholders. This innovation not only addresses current limitations but also paves the way for increased use of blockchain solutions in the supply chain environment.
