Public Philanthropy Logistics Platform Based on Blockchain Technology for Social Welfare Maximization

Focusing on the overlapping areas of the logistics industry with a large number of mature blockchain applications and the public welfare industry that requires high transparency and credibility, this paper designs and implements an innovative philanthropy logistics platform based on blockchain technology through the Ethereum platform. Our platform makes use of the open, transparent, and irrevocable features of the blockchain, combined with a unique Responsibility Relay System and Evaluation and Reporting Mechanism, and can achieve the consistency of the data on the chain with real-world status, as well as the authenticity and transparency of philanthropy logistics data. This paper also establishes a model for evaluating philanthropy material donations for social welfare based on the classic network maximum flow algorithm. After four months of empirical analysis, we have concluded that the blockchain platform can greatly increase the user's trust in the project, enhance the system's cleanliness coefficient and increase the quality of philanthropically raised materials, thereby improving the public welfare of charitable donations. The paper draws the conclusion that this blockchain platform is a technical solution for maximizing social welfare.
