Smart Contracts on Ethereum for Smart Supply Chain Management

Abstract

Raw materials are manually produced, and data is often stored and managed insecurely, leading to increased overall time and dissatisfaction among clients. Blockchain technology, with its decentralization and robust security, revolutionizes data storage by improving data security, time management, and transaction efficiency. This chapter examines the use of Ethereum-based smart contracts to enhance supply chain management, streamline transactions, safeguard data, and optimize time management. By establishing legally binding agreements, smart contracts reduce ambiguity in operations. However, Smart Contract Management (SCM) tags are costly and have limited lifespans. Supply chain management is inherently sensitive, and logistics require strict confidentiality to protect product information. The study aims to decouple supply chain processes from data security concerns, addressing the challenges posed by outdated systems that have persisted for decades. Key areas of focus include inventory management, product quality, and resolving supply-demand discrepancies, with data security being a critical priority. This proposed solution integrates smart contracts and peer-to-peer encryption, leveraging the immutability of blockchain ledgers to prevent unauthorized access by hackers. Registered users gain secure website access, ensuring controlled data sharing. Cryptographic methods further enhance transaction security, while damaged products can be retained as evidence for dealer compensation. This approach is not only secure and effective but also instills greater customer confidence during transactions. By modernizing supply chain systems, this study demonstrates the potential to transform the industry, making operations more efficient, user-friendly, and reliable.
