The existing processes, techniques, and technologies utilized in the auction system to process the supply chain of commodities are inefficient. They face several challenges in terms of security, dependability, non-modification, traceability, and operational transparency. They also have issues with centralization. Traditional supply chain systems are centralized, vulnerable to single points of failure, and provide ambiguous product information. A decentralized blockchain-based solution was proposed to provide new ideas for the supply chain management process of auction system commodities in a totally secure, transparent, unmodifiable, traceable, and trustworthy manner. This paper combined Ethereum and the interplanetary file system (IPFS) to safely and reliably collect, store, and communicate data pertaining to the auction system's commodity supply chain.
