In recent years, corporate social responsibility has become an integral part of business strategies. In food supply chains, adhering to ethical principles and paying attention to social and environmental issues at all stages of production and distribution can help strengthen brand credibility, attract loyal customers, and achieve sustainable success in the market. Additionally, to ensure food safety and control the spread of foodborne diseases, implementing an efficient tracing system for food products is essential. At the same time, the coordination of food supply chains has gained significant importance due to the substantial reduction in costs and improvement in profitability. To this end, in this research, three proposed models for coordinating a two-stage food supply chain with a focus on corporate social responsibility under stochastic demand with partial information are introduced. Due to financial, ethical, and environmental scandals involving some manufacturers who have failed to meet social responsibility commitments, consumers often doubt the validity of these claims. In this regard, the first proposed model explores the impact of consumer distrust on the validity of social responsibility claims, taking into account the information asymmetry of the associated costs. The second proposed model addresses the challenge of distrust and establishes a food product tracing system using blockchain technology, examining information asymmetry through the new concept of access levels in a private blockchain. The third proposed model examines the role of the government as a distinct and independent stage by considering reward tokens to support a socially responsible manufacturer and a smart contract based on a reward/penalty mechanism to mandate and encourage the supply chain to establish and improve the tracing system through blockchain technology. Finally, the accuracy and validity of the proposed models are eva‎luated through numerical examples and sensitivity analysis regarding key parameters. The results indicate that using blockchain technology to build trust and trace food products increases market demand and, consequently, the profitability of supply chain members. Additionally, the two-part tariff coordination contract encourages the manufacturer to adopt greater social responsibility and leads to reach profitability in centralized decision-making. Furthermore, government intervention effectively strengthens corporate social responsibility initiatives and the blockchain-based tracing system, enhancing the profitability of supply chain members.
