To address these challenges, blockchain-based transaction models proposed. lack system integrity fail fully meet user requirements while ensuring adequate security. overcome limitations, this paper presents an Ethereum-based model that establishes a comprehensive secure system. The aims provide users with more convenient, secure, professional services. Through utilization smart contracts, can efficiently match negotiate prices online delivery through encryption technologies. Additionally, introduces trusted third-party entity offers evaluation services actively safeguards ownership event disputes. implementation includes development contracts necessary machine learning code, followed by rigorous testing validation. experimental results validate effectiveness reliability our proposed model, demonstrating its potential ensure effective
